AB  - Background The emergence of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in early 2020 and subsequent implementation of public health and social measures (PHSM) disrupted the epidemiology of respiratory viruses. This work describes the epidemiology of respiratory syncytial virus (RSV) observed during two winter seasons (weeks 40–20) and inter-seasonal periods (weeks 21–39) during the pandemic between October 2020 and September 2022. Methods Using data submitted to The European Surveillance System (TESSy) by countries or territories in the World Health Organization (WHO) European Region between weeks 40/2020 and 39/2022, we aggregated country-specific weekly RSV counts of sentinel, non-sentinel and Severe Acute Respiratory Infection (SARI) surveillance specimens and calculated percentage positivity. Results for both 2020/21 and 2021/22 seasons and inter-seasons were compared with pre-pandemic 2016/17 to 2019/20 seasons and inter-seasons. Results Although more specimens were tested than in pre-COVID-19 pandemic seasons, very few RSV detections were reported during the 2020/21 season in all surveillance systems. During the 2021 inter-season, a gradual increase in detections was observed in all systems. In 2021/22, all systems saw early peaks of RSV infection, and during the 2022 inter-seasonal period, patterns of detections were closer to those seen before the COVID-19 pandemic. Conclusion RSV surveillance continued throughout the COVID-19 pandemic, with an initial reduction in transmission, followed by very high and out-of-season RSV circulation (summer 2021) and then an early start of the 2021/22 season. As of the 2022/23 season, RSV circulation had not yet normalised.

AB  - One consequence of the ongoing coronavirus disease pandemic was the rapid development of both in-house and commercial serological assays detecting anti-SARS-CoV-2 antibodies, in an effort to reliably detect acute and past SARS-CoV-2 infections. It is crucial to evaluate the quality of these serological tests and consequently the sero-epidemiological studies that are performed with the respective tests. Here, we describe the set-up and results of a comparative study, in which a laboratory contracted by the European Centre for Disease Prevention and Control offered a centralised service to EU/EEA Member and pre-accession Member States to test representative serum specimens with known serological results, with the gold standard technique (virus neutralisation tests) to determine the presence of neutralising antibodies. Laboratories from 12 European countries shared 719 serum specimens with the contractor laboratory. We found that in-house serological tests detecting neutralising antibodies showed the highest percent agreement, both positive and negative, with the virus neutralisation test results. Despite extensive differences in virus neutralisation protocols neutralisation titres showed a strong correlation. From the commercial assays, the best positive percent agreement was found for SARS-CoV-2 IgG (sCOVG) (Siemens - Atellica IM Analyzer). Despite lower positive percent agreement of LIAISON SARS-CoV-2 TrimericS IgG kit (Diasorin Inc.), the obtained results showed relatively good correlation with neutralisation titres. The set-up of this study allowed for high comparability between laboratories and enabled laboratories that do not have the capacity or capability to perform VNTs themselves. Given the variety of in-house protocols detecting SARS-CoV-2 specific neutralising antibodies, including the virus strain, it could be of interest to select reference isolates for SARS-CoV-2 diagnostic to be made available for interested EU Member States and pre-accession countries.

AB  - Background: Recent literature data highlights metabolic changes in amyotrophic lateral sclerosis (ALS). To explore possible early metabolic changes, we aimed to analyse the fatty acids (FA) composition of erythrocytes in newly diagnosed als patients and to see whether fatty acid levels correlate with the ALSFRS-R score or disease duration. Methods: The severity of motor function involvement was assessed by the ALSFRS-R scale at the initial evaluation. The fatty acid profile of erythrocyte membranes was analysed by gas-liquid chromatography. The study comprised 26 clinically diagnosed als patients, with mean ALSFRS-R 38±8. The control group included 26 healthy volunteers. Results: Significantly higher levels of palmitic acid and total saturated FAs were detected in als patients. In als patients, total monounsaturated FA, palmitoleic, vaccenic, and oleic acid were also significantly increased. The levels of eicosapentaenoic acid, docosapentaenoic acid, total polyunsaturated FA (PUFA) and n-6 PUFA were significantly lower in als patients. Additionally, a-linolenic acid, the precursor of the n-3 PUFA family, was not detected in als patients. We found no significant correlation between the ALSFRS-R score and the abundance of individual FAs analysed. A moderate negative correlation was found between disease duration and DHA level, and a positive correlation was detected with MUFA. Conclusion: Experimental evidence presented may contribute to shaping a beneficial nutritional intervention.

AB  - The size of circulating immune complexes (CICs) in rheumatoid arthritis (RA) could be an emerging criterion in disease diagnosis. This study analyzed size and electrokinetic potential of CICs from RA patients, healthy young adults, and RA patients age-matched controls aiming to establish their unique CIC features. Pooled CIC of 30 RA patients, 30 young adults, and 30 RA group's age-matched controls (middle-aged and oldеr healthy adults), and in vitro IgG aggregates from pooled sera of 300 healthy volunteers were tested using dynamic light scattering (DLS). Size distribution of CIC in healthy young adults exhibited high polydispersity. RA CIC patients and their age-matched control showed distinctly narrower size distributions compared with young adults. In these groups, particles clustered around two well-defined peaks. Particles of peak 1 were 36.1 ± 6.8 nm in RA age-matched control, and 30.8 ± 4.2 nm in RA patients. Particles of peak 2 of the RA age-matched control's CIC was 251.7 ± 41.2 nm, while RA CIC contained larger particles (359.9 ± 50.5 nm). The lower zeta potential of RA CIC, compared to control, indicated a disease-related decrease in colloidal stability. DLS identified RA-specific, but also age-specific distribution of CIC size and opened possibility of becoming a method for CIC size analysis in IC-mediated diseases.

AB  - Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, affecting motor neurons, which is characterized by the progressive loss of motor function. Sufficient evidence has been gathered, either in the form of experimental results from animal disease models or from the assessment of affected human subjects, which implicates metabolic changes in the course of ALS. Hypermetabolism, abnormal glucose tolerance and dyslipidaemia were reported to have high incidence in ALS patients. In fact, according to published studies, BMI is significantly and inversely associated with ALS progression. Here, we discuss basic principles of fatty acid metabolism, composition and the existing knowledge of metabolic and fatty acid composition changes in ALS patients. Literature data suggest that ALS patients have unfavorable changes in the fatty acid profile, especially because of the low level of long-chain polyunsaturated fatty acids. Nutritional interventions and supplementation with various foods or food supplements are currently not showing conclusive results, implying there is more to learn about potential ways to modify this illness.

AB  - Poskok (Vipera ammodytes) predstavlja najzastupljeniju zmiju otrovnicu u Srbiji i na Balkanu, kako po brojnosti tako i po arealu rasprostranjenosti. U poređenju sa venomima ostalih otrovnica iz familije Viperidae na Balkanu, toksičnost venoma poskoka je najveća. Neurotoksičnost sirovog venoma poskoka smo ispitivali u in vitro uslovima na osnovu kontrakcija preparata dijafragme izazvanih poljnom električnom stimulacijom i aktivnosti enzima: acetilholinesteraze (AChE) i ukupnih ATP-aza u dijafragmi.Formirano je 5 grupa pacova (n=5): kontrola (dijafragma bez venoma), dijafragma sa venomom, dijafragma sa smešom venom/antivenom („Viekvin“, Torlak, Srbija) u odnosima 1:2, 1:10 i 1:20 (m/m). Kontrakcije dijafragme su opale na 50% kontrolnih kontrakcija: pod uticajem venoma za 62,00±2,31minuta, a sa smešom venom/antivenom 1:2 za 78,50±7,51 minuta, 1:10 za 150,00±17,32 minuta, 1:20 za 307,50±2,89 minuta. Statistička razlika (p0,05) pod dejstvom venoma. Venom inhibira aktivnost ukupnih ATP-aza dijafragme za 51,81% u odnosu na kontrolu.

AB  - Vipera ammodytes is the most common venomous snake in Serbia and the Balkans, both in terms of numbers and area of distribution. Compared to the venoms of other poisonous snakes from the family Viperidae in the Balkans, the toxicity of the V. ammodytes venom is the highest. We investigated the neurotoxicity of crude venom in vitro using contractions of the diaphragm preparation induced by electric field stimulation and enzyme activity: acetylcholinesterase (AChE) and total ATPases in the diaphragm. Five groups of rats were formed (n=5): control (diaphragm without venom), diaphragmwith venom, diaphragm with mixture of venom/antivenom ("Viekvin", Torlak, Serbia) in the ratio 1:2, 1:10 and 1:20 (m/m). Diaphragmatic contractions decreased to 50% of control contractions: under the influence of venom for 62.00±2.31 minutes, and with venom/antivenom mixture 1:2 for 78.50±7.51 minutes, 1:10 for 150.00±17.32 minutes, 1:20 for 307.50±2.89 minutes. A statistical difference (p 0.05) under the influence of the venom. Venom inhibits the total ATPases activity of the diaphragm by 51.81% compared with control.The venom of V. ammodytes does not act on AChE and nicotinic receptors in the neuromuscular synapse of the diaphragm, but interferes with mitochondrial energy metabolism.

AB  - Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its resulting coronavirus disease 2019 (COVID-19) has caused a fast-moving pandemic. Diagnostic testing, aimed to identify patients infected with SARS-CoV-2, plays a key role in controlling the COVID-19 pandemic in different populations. (2) Methods: This retrospective cohort study aimed to investigate predictors associated with positive polymerase chain reaction (PCR) SARS-CoV-2 test results in hospitalized patients, healthcare workers (HCWs), and military personnel (MP) during 2020, before the widespread availability of COVID-19 vaccines. Persons with a positive test result were compared with persons with a negative test result in three cohorts during the study period. (3) Results: A total of 6912 respondents were tested, and 1334 (19.3%) of them had positive PCR SARS-CoV-2 test results. Contact with a known COVID-19 case within 14 days (p < 0.001; OR: 1.48; 95% CI: 1.25–1.76), fever (p < 0.001; OR: 3.66; 95% CI: 3.04–4.41), cough (p < 0.001; OR: 1.91; 95% CI: 1.59–2.30), headache (p = 0.028; OR: 1.24; 95% CI: 1.02–1.50), and myalgia/arthralgia (p < 0.001; OR: 1.99; 95% CI: 1.65–2.42) were independently associated with positive PCR SARS-CoV-2 test results in the cohort of MP. Furthermore, fever (p < 0.001; OR: 2.75; 95% CI: 1.83–4.13), cough (p < 0.001; OR: 2.04; 95% CI: 1.32–3.13), headache (p = 0.008; OR: 1.76; 95% CI: 1.15–2.68), and myalgia/arthralgia (p = 0.039; OR: 1.58; 95% CI: 1.02–2.45) were independently associated with positive PCR SARS-CoV-2 test results in the cohort of HCWs. Moreover, independent predictors of positive PCR SARS-CoV-2 test results in hospitalized patients were contact with a known COVID-19 case within 14 days (p < 0.001; OR: 2.56; 95% CI: 1.71–3.83), fever (p < 0.001; OR: 1.89; 95% CI: 1.38–2.59), pneumonia (p = 0.041; OR: 1.45; 95% CI: 1.01–2.09), and neurological diseases (p = 0.009; OR: 0.375; 95% CI: 0.18–0.78). (4) Conclusions: According to data gathered from cohorts of hospitalized patients, HCWs, and MP, before the widespread availability of COVID-19 vaccines in Serbia, we can conclude that predictors of positive PCR SARS-CoV-2 test results in MP and HCWs were similar. Accurate estimates of COVID-19 in different population groups are important for health authorities.

AB  - The study was aimed to examine putative contribution of thymic involution to ageing-associated increase in susceptibility of Albino Oxford (AO) rats to the development of clinical EAE, and vice versa influence of the disease on the progression of thymic involution. To this end we examined (i) the parameters of thymocyte negative selection efficacy, the thymic generation of CD4+CD25+Foxp3+ T regulatory cells (Tregs) and thymic capacity to instruct/predetermine IL-17-producing T-cell differentiation, and thymopietic efficacy-associated accumulation of “inflammescent” cytotoxic CD28- T cells in the periphery, and (ii) the key underlying mechanisms in young and old non-immunised AO rats and their counterparts immunised for EAE (on the 16th day post-immunisation when the disease in old rats reached the plateau) using flow cytometry analysis and/or RT-qPCR. It was found that thymic involution impairs: (i) the efficacy of negative selection (by affecting thymocyte expression of CD90, negative regulator of selection threshold and the expression of thymic stromal cell integrity factors) and (ii) Treg generation (by diminishing expression of cytokines supporting their differentiation/maturation). Additionally, the results suggest that thymic involution facilitates CD8+ T-cell differentiation into IL-17-producing cells (previously linked to the development of clinical EAE in old AO rats). Furthermore, they confirmed that ageing-related decrease in thymic T-cell output (as indicated by diminished frequency of recent thymic emigrants in peripheral blood) resulted in the accumulation of CD28- T cells in peripheral blood and, upon immunisation, in the target organ. On the other hand, the development of EAE (most likely by increasing circulatory levels of proinflammatory cytokines) contributed to the decline in thymic output of T cells, including Tregs, and thereby to the progression/maintenance of clinical EAE. Thus, in AO rats thymic involution via multi-layered mechanisms may favour the development of clinically manifested autoimmunity, which, in turn, precipitates the thymus atrophy.

AB  - Introduction: Brevibacillus laterosporus is a promising microbiological agent that can be used to prevent and control destructive diseases affecting honey bee colonies. In the presentstudy, the short-termeffect of the B. laterosporus BGSP11 bee diet on microbiota and mycobiota was investigated.Methods: The honey bee diet was supplemented with spores of B. laterosporus BGSP11 at a concentration of 1×108 CFU/mL in sucrose solution. Metabarcoding analysis of the bee microbial community profile was performed based on 16S RNA (bacteriobiota) and Internally Transcribes Spacer (ITS) region(mycobiota) obtained using MiSeq Illumina sequencing. The QIIME2 v2021.4 pipeline was used to analyze the obtained amplicon data library.Results: The results show that the BGSP11 bee diet slightly altered the bee microbiota and did not leadto potentially harmful changes in the bacterial microbiota. Moreover, it can potentially induce positivechanges, mainly reflected in the reduction of opportunistic bacteria. On the other hand, the treatmenthad a greater effect on mycobiota. However, the changesin the bee mycobiome caused by the treatmentcannot be considered a priori as beneficial or harmful,since the interaction between the bee and its mycobiome is not sufficiently studied. The observed positive changes in the bee mycobiome are mainlyreflected in the reduction of phytopathogenic fungi that may affect the organoleptic and techno-functional properties of honey.Conclusion: This pilot study suggests that the introduction of BGSP11 in beekeeping practice as a biological agent could be considered due to no harmful effects observed on the microbiota of bees.

AB  - Introduction: Resurrection plants (such as Ramonda serbica) can survive a long desiccation period andfully resume their metabolism upon watering. The hallmark of desiccation tolerance (DT) is the accumulation of protective, intrinsically disordered proteins(IDPs), called late embryogenesis abundant proteins (LEAPs). Although their high structural plasticity allows them to interact with various partners, nospecific cellular targets of LEAPs have been identified so far.Methods: To identify LEAPsinvolved in DT, differential transcriptome and proteome analyses of hydratedand desiccated R. serbica leaves were performed. The identified LEAPs were structurally characterisedand classified. To evaluate theirstructural propertiesin vitro and their potential functionsin vivo, the representative RsLEA proteins, were produced in Escherichia coli using recombinant DNA technology.Results: Members of the LEA4 protein family represent the majority of desiccation-inducible LEAPs. Even17 proteins belonging to the LEA4 protein family group were induced by desiccation. They show high disorder propensity (82 %), and at the same time, a high tendency to form α-helices (>80%). Although recombinant DNA technology has traditionally been used to overexpress and purify various globularproteins, the production of IDPsis challenging due to their high susceptibility to proteolytic cleavage andaggregation. Nevertheless, the representative LEAPs containing hexa-Histagsimmunoglobulin G-binding protein and a proteolytic TEV site were produced, purified and cleaved by TEV protease.Conclusion: The combination of in silico and in vitro results will be crucial for the identification of endogenous partners of LEAPs, providing further insight into their role in DT.

AB  - Introduction: Lactolisterin BU (LBU) is a potent bacteriocin derived from Lactococcuslactis subsp. lactis
bv. diacetylactis BGBU1-4. It exhibits antimicrobial properties against Gram-positive food spoilage and
foodborne pathogens. This research aimed to explore the impact of amino acid substitution in LBU on
its antimicrobial activity by utilizing in silico prediction of LBU’ssecondary structure and amino acid substitutions.
Methods: The secondary structure of LBU was predicted using Phyre2 software. Five variants of LBU
were selected and chemically synthesized, along with unaltered LBU and BHT-B,serving as controls. Peptides were twofold diluted in distilled water, resulting in final concentrations ranging from 1000 µg/ml
to 0.5 µg/ml. An agarspot test, employing 5 µl of the dilution, was conducted on three indicatorstrains:
Lactococcus lactis BGMN1-596, Listeria monocytogenes ATCC19111, and Staphylococcus aureus
ATCC25923. The presence of inhibition zones was analyzed after overnight incubation at 37°C (S. aureus)
and 30°C (L. lactis and L. monocytogenes).
Results: Phyre2 analysis unveiled the presence of two α-helices in LBU’s structure. The majority of LBU
variants displayed altered antimicrobial activity, with some changes being genusspecific, potentially attributable to variances in cell wall composition. Some variants completely lost their activity, underscoring the significance of native amino acids or their physicochemical properties in the corresponding
positions within LBU’s structure. Furthermore, it was confirmed that chemically synthesized LBU effectively retains its antimicrobial activity.
Conclusion: Changesin amino acid composition give insight on structure-function relationship of LBU.

AB  - Introduction: Ankyrin Repeat Domain 2 (ANKRD2) is expressed in skeletal muscle, where plays a role inmuscle development, differentiation and adaptation to stress. Human skeletal muscle consists of threemajor fiber types: type 1 (slow-twitch, oxidative), type 2A (fast-twitch, oxidative) and type 2X (fast-twitch,glycolytic). ANKRD2 is reported to be primarily expressed in type 1 myofibers. However, recent findingson human single myofibers and our study of chicken muscles have shown that this protein may also beexpressed in type 2A fibers. Hence, our objective was to examine whether ANKRD2 is present in humanfast, type 2A muscle fibers using immunohistochemistry.Methods: Samples of large leg musclessoleus, gastrocnemius, vastusintermedius and vastuslateralis wereobtained from human cadaveric tissue. Serial cryosections were independently stained with anti-ANKRD2and antibodies for different myosin heavy chain isoforms (6H1 for type 2X, BF35 for type 1 and 2A, antiMHCs for type 1 and anti-MHCf for type 2A and 2X fibers). Immunostained tissues were analyzed by fluorescent microscopy.Results: In addition to slow, type 1, ANKRD2 wasfound expressed in fast, type 2A myofibers, which bothhave oxidative metabolism. Further, we did not observe ANDRD2 expression in glycolytic, type 2Xmyiofibers. This pattern of ANKRD2 expression was consistent across all examined muscles.Conclusion: Our resultsimplicate that the regulatory mechanism of ANKRD2 expression in human skeletal muscle is associated with oxidative metabolism, rather than muscle contraction speed.

AB  - Introduction: Quorum quenching (QQ) isthe enzymatic degradation of cell-to-cellsignaling molecules.
In this study, the potential of the novel YtnP lactonase, the quorum quenching enzyme derived from S.
maltophilia, to reduce P. aeruginosa quorum sensing and virulence factor gene expression was investigated.
Methods: MMA83 culture (adjusted to 1.5x105 CFU/ml) was treated with recombinant YtnP lactonase
(final concentration 50 μg/ml) at 37°C for 12 hours under aeration. RNA isolation of the treated and untreated MMA83 culture was performed using the RNeasy Mini Kit (Qiagen, Germany) according to the
protocol. Quantitative reverse transcription-polymerase chain reaction (RT-qPCR), was used to analyze
the effect ofYtnP lactonase on the relative mRNA levels of the LasI/LasR, RhiI/RhiR, and PQS signaling network genes of P. aeruginosa MMA83 and virulence factor genes. The rpsL was used as an endogenous
control to normalize obtained data following the 2-ΔΔCt method.
Results: The QS genes belonging to three QS networks – LasI/LasR, RhiI/RhiR, and PQS of P. aeruginosa
MMA83 treated with YtnP lactonase were significantly downregulated. The RT -qPCR results show that
treatment with YtnP-lactonase decreased the relative mRNA levels of genes involved in the production
of elastase (lasB approximately 2-fold), alginate (algK approximately 2.2-fold), pyocyanin (phzM approximately 3.5-fold), pyoverdin (pvdS approximately 2-fold), and rhamnolipid (rhlC approximately 4-fold).
These results suggest that YtnP lactonase exerts an antivirulence effect at the transcription level.
Conclusion: YtnP lactonase, a quorum quenching (QQ) enzyme, has the potential to be used as an innovative enzyme-based antivirulence therapeutic to combat infections caused by P. aeruginosa.

AB  - Thermally processed peanuts are ideal plant models for studying the relationship between allergenicity and antioxidant capacity of protein-rich foods, besides lipids, carbohydrates and phytochemicals. Peanut is highly praised in the human diet; however, it is rich in allergens (>75% of total proteins). One-third of peanut allergens belong to the products of genes responsible for the defence of plants against stress conditions. The proximate composition of major peanut macromolecules and polyphenols is reviewed, focusing on the identity and relative abundance of all peanut proteins derived from recent proteomic studies. The importance of thermal processing, gastrointestinal digestion (performed by INFOGEST protocol) and their influence on allergenicity and antioxidant properties of protein-rich plant food matrices is elaborated. Antioxidant properties of bioactive peptides from nuts were also considered. Moreover, there are no studies dealing simultaneously with the antioxidant and allergenic properties of protein- and polyphenol-rich foods, considering all the molecules that can significantly contribute to the antioxidant capacity during and after gastrointestinal digestion. In summary, proteins and carbohydrates are underappreciated sources of antioxidant power released during the gastrointestinal digestion of protein-rich plant foods, and it is crucial to decipher their antioxidant contribution in addition to polyphenols and vitamins before and after gastrointestinal digestion.

AB  - Food allergies have increased dramatically in the last decade, especially in developedcountries. Food tolerance requires strict maintenance of a specific microbial portfolio inthe gastrointestinal tract, as changes in the gut microbiome can lead to its disruption,which in turn causes inflammation and pathogenic gut conditions leading to thedevelopment of food allergies. Any environmental factors that lead to a disturbanceand/or malfunction of the gastrointestinal tract and digestive performance favor thedevelopment of food allergies.Based on that, what do we know about the role of increasing anthropogenic chemicals,including emerging ones, resulting from the new global situation?There is awareness that their effects are multifaceted, e.g., chemicals affect the growth ofplants and animals and thus the quality of the food produced. In addition, chemicals affectour food during its production and processing, but also affect our body andgastrointestinal tract. It is time to fill the knowledge gaps and understand how theseinteractions between environmental triggers such as industrial and traffic pollution,transition and heavy metals, pesticides, chemtrails, etc., affect food allergens and theirallergenicity, adjuvant effects, and the increasing prevalence of food allergies.Some improvements in this area are already being made through advances in ‘omics’technologies (i.e., proteomics, genomics, metabolomics) and systems biology approachesthat will hopefully provide a scientific understanding of the relationship betweenincreasing food allergies and the increasingly present wide variety of anthropogenicchemicals in our environment.

AB  - Allergen immunotherapy (AIT) is currently the only disease-modifying treatment for
allergies. Pre-clinical models for the evaluation of novel therapeutics are crucial for
ensuring their efficacy and safety. While cell culture models are cost-effective and
efficient, they cannot fully replicate the cellular interactions in vivo. Therefore, it is
essential to use more sophisticated model systems, such as co-cultures, to assess the
potential of new therapeutics more accurately. Immunomodulatory protein banana lectin
(BLwt) is an attractive candidate for adjuvant in AIT. Its mutant BLH84T was developed to
reduce its potential mitogenicity. The aim of this study was the development of the coculture model system for testing the immunomodulatory effect of chimeras composed of
the major birch pollen allergen (Bv1a) and BLwt (Bv1a-BLwt, Cwt), the hypoallergenic
isoform of Bv1a (Bv1l) and BLH84T (Bv1l-BLH84T, C1 and BLH84T-Bv1l, C2). Chimeric
structures were designed in silico, fully minimized, and relaxed without van der Waals
atomic clashes. Afterward, proteins were successfully expressed in Escherichia coli and
purified by IMAC yielding around 0.4 mg per 1L of expression medium. The IgE binding
capacity was assessed using ELISA inhibition with birch pollen allergic patients’ sera.
Caco-2 intestinal epithelial cells and THP-1 differentiated macrophages were used for the
co-culture model system development. After protein application on the apical side of the
co-culture, the integrity of the epithelial monolayer was not disturbed. The
immunomodulatory potential of antigens was tested by measuring the gene expression
levels for pro- and anti-inflammatory cytokines in both cell lines from co-culture. The
obtained results indicate that the best anti-inflammatory response was favored after
treatment with Cwt. Additionally, to further confirm the immunomodulatory effect of the
recombinant chimeras, PBMCs obtained from individuals allergic to birch pollen were
employed and treated with recombinant proteins. Only after treatment with Cwt, PBMCs
secreted the anti-inflammatory cytokine IL-10. Obtained results suggest that Cwt chimera
could have a therapeutic effect in AIT in birch pollen allergy.

AB  - Lactic acid bacterium Lactococcus lactis BGBU1-4 produces 43 amino acids (aa) long bacteriocin, lactolisterin BU (LBU), a 5.161 kDa peptide with potent antibacterial activity against many Gram-positive pathogens. In addition, BGBU1-4 produces an additional unknown product of 3.642 kDa with antibacterial activity. Here, we determined that the significant amount of naturally produced LBU breaks down to create a 3.642 kDa truncated form of LBU bacteriocin consisting of 31 N-terminal aa (LBU1-31) that exhibits 12.5% the antibacterial activity of the full-length LBU. We showed that chemically synthesized LBU is stable and 50% less active than native LBU, and so we used the synthetic peptides of LBU and its variants to further study their activities and antibacterial potential. Deletion analysis of LBU revealed that the 24 N-terminal aa of LBU (LBU1-24) are responsible for antibacterial activity, while downstream aa (25–43) determine the species-specific effectiveness of LBU. Although LBU1-31 contains aa 1–24, the truncation at position 31 is predicted to change the structure within aa 15–31 and might impact on antibacterial activity. Intriguingly, whole genome sequencing and genome mining established that BGBU1-4 is abundant in genes that encode potential antibacterials, but produces LBU and its breakdown product LBU1-31 exclusively.

Deletion analysis of LBU revealed that the 24 N-terminal aa of LBU (LBU1-24) are responsible for antibacterial activity, while downstream aa (25–43) determine the species-specific effectiveness of LBU. Although LBU1-31 contains aa 1–24, the truncation at position 31 is predicted to change the structure within aa 15–31 and might impact on antibacterial activity. Intriguingly, whole genome sequencing and genome mining established that BGBU1-4 is abundant in genes that encode potential antibacterials, but produces LBU and its breakdown product LBU1-31 exclusively.",

AB  - The combination of b-oligosaccharides from enzymatically hydrolysed barley b-glucan has attracted interest recently due to its positive effects on human health. This study aimed to assess the impact of the
endo-b-1,3-1,4-glucanase enzyme from Bacillus subtilis 168 on improving the nutritional and bioactive
properties of barley b-glucan. A new procedure for the isolation of b-glucan was developed, at a lower
temperature (45 °C), enabling purity from starch contamination, without affecting the yield (6 g b-glucan
from 100 g of barley flour). The endo-b-1,3-1,4-glucanase is cloned into E. coli pQE_Ek enables the high
production and purification (82% yield, 1.8 mg mL 1 and 440 U mg 1
) of an enzyme identical to the
natural one (25.5 kDa). The enzymatic reaction showed high efficiency of b-glucan degradation by recombinant enzyme, giving a mixture of products (of which 3-O-b-cellobiosyl-D-glucose and 3-O-b-cellotriosylD-glucose are the most abundant), the reduction of viscosity (17%) and increase in antioxidant capacities
by 15.2%, 30.9% and 44.0% assessed by ABTS, DPPH and ORAC, respectively. These results indicate
the possible application of endo-b-1,3-1,4-glucanase enzyme in improving the properties of barley bglucan used as functional foods.

AB  - α-Amylase from the thermophilic bacterial strain Anoxybacillus vranjensis ST4 (AVA) was cloned into the pMALc5HisEk expression vector and successfully expressed and purified from the Escherichia coli ER2523 host strain. AVA belongs to the GH13_5 subfamily of glycoside hydrolases and has 7 conserved sequence regions (CSRs) distributed in three distinct domains (A, B, C). In addition, there is a starch binding domain (SBD) from the CBM20 family of carbohydrate binding modules (CBMs). AVA is a monomer of 66 kDa that achieves maximum activity at 60–80 °C and is active and stable over a wide pH range (4.0–9.0). AVA retained 50 % of its activity after 31 h of incubation at 60 °C and was resistant to a large number of denaturing agents. It hydrolyzed starch granules very efficiently, releasing maltose, maltotriose and maltopentaose as the main products. The hydrolysis rates of raw corn, wheat, horseradish, and potato starch, at a concentration of 10 %, were 87.8, 85.9, 93.0, and 58 %, respectively, at pH 8.5 over a 3 h period. This study showed that the high level of expression as well as the properties of this highly stable and versatile enzyme show all the prerequisites for successful application in industry.

AB  - This review summarizes recent findings related to the role of the sympathetic nervous system (SNS) in pathogenesis of multiple sclerosis (MS) and its commonly used experimental model – experimental autoimmune encephalomyelitis (EAE). They indicate that noradrenaline, the key end-point mediator of the SNS, acting through β-adrenoceptor, has a contributory role in the early stages of MS/EAE development. This stage is characterized by the SNS hyperactivity (increased release of noradrenaline) reflecting the net effect of different factors, such as the disease-associated inflammation, stress, vitamin D hypovitaminosis, Epstein-Barr virus infection and dysbiosis. Thus, the administration of propranolol, a non-selective β-adrenoceptor blocker, readily crossing the blood-brain barrier, to experimental rats before the autoimmune challenge and in the early (preclinical/prodromal) phase of the disease mitigates EAE severity. This phenomenon has been ascribed to the alleviation of neuroinflammation (due to attenuation of primarily microglial activation/proinflammatory functions) and the diminution of the magnitude of the primary CD4+ T-cell autoimmune response (the effect associated with impaired autoantigen uptake by antigen presenting cells and their migration into draining lymph nodes). The former is partly related to breaking of the catecholamine-dependent self-amplifying microglial feed-forward loop and the positive feedback loop between microglia and the SNS, leading to down-regulation of the SNS hyperactivity and its enhancing influence on microglial activation/proinflammatory functions and the magnitude of autoimmune response. The effects of propranolol are shown to be more prominent in male EAE animals, the phenomenon important as males (like men) are likely to develop clinically more severe disease. Thus, these findings could serve as a firm scientific background for formulation of a new sex-specific immune-intervention strategy for the early phases of MS (characterized by the SNS hyperactivity) exploiting anti-(neuro)inflammatory and immunomodulatory properties of propranolol and other relatively cheap and safe adrenergic drugs with similar therapeutic profile.

AB  - Diazinon is an organophosphate pesticide (OP) that has significant potential for accidental and intentional poisoning of wildlife, domestic animals and humans. The aim of the study is to investigate the correlation between cholinesterase activity and oxidative stress parameters in liver and diaphragm by continuous monitoring as a function of time during prolonged use of diazinon. Wistar rats were treated orally with diazinon (55 mg/kg/day): 7, 14, 21 and 28 days. At the end of each period, blood, liver and diaphragm were collected to examine cholinesterase activity and enzymatic/non-enzymatic oxidative stress parameters: superoxide dismutase 1 (SOD1), catalase (CAT), thiobarbituric acid substances (TBARS), protein carbonyl groups. In all four time periods, there was a significant change in acetylcholinesterase (AChE) in erythrocytes and butyrylcholinesterase (BuChE) in blood plasma, CAT in liver and diaphragm and SOD1 in diaphragm. Parameters significantly altered during the cholinergic crisis included: cholinesterases and TBARS in liver and diaphragm and partially SOD1 in liver. Protein carbonyl groups in liver and diaphragm were significantly altered outside the cholinergic crisis. In the liver, there was a very strong negative correlation between BuChE and TBARS in all four time periods and BuChE and CAT on day 7. In the diaphragm, a very strong negative correlation was found between AChE and TBARS at days 7 and 14, and a very strong positive correlation between AChE and SOD1 at days 14, 21 and 28. A better understanding of the relationship between cholinergic overstimulation and oxidative stress may help to better assess health status in prolonged OPs intoxication.
