AB  - Objective: Haliotis discus (Japanese abalone), mollusks among various shellfish, is a highlynutritive food resource in the world, but also among the eight allergic food groups accounting forapproximately 90% of all immunoglobulin E food allergies worldwide. The general objective of ourresearch is to comprehensively investigate stability and structures of pepsin-resistant allergens, oftheir larger fragments, and of short digestion resistant peptides (SDRPs) released by pepsindigestion of whole raw and extract of shellfish, under standardized and physiologically relevantgastric conditions.Materials and Methods: Extract of raw whole shellfish (eRSS) and whole raw shellfish (wRSS),were pepsin digested according to standardized static digestion protocol. Controls were treated in asame manner without adding pepsin. Supernatant of samples and its counterpart controls wereprecipitated with TCA/acetone. Obtained proteins were assessed by 2D SDS PAGE and 1D SDS-PAGE, under reducing and non-reducing conditions. 1D SDS-PAGE of RSS were analyzed byncLC-MS/MS (Orbitrap LTQ) shot-gun proteomics. Relative quantification was performed by LFQalgorithm within Peaks 8.5 software package Bioinformatics Solutions Inc. (BSI), Waterloo,Canada.Results and Conclusion: 1D SDS-PAGE analysis of eRSS and wRSS, and its controls showed arange of proteins in varied concentrations between 10-250 kDa. In extracted and whole rawshellfish, approximately 22 prominent protein bands were observed including the distinct bandscorresponding with the molecular weights of recognized shellfish allergen, tropomyosin (37-39kDa). Fewer high molecular weight proteins were observed followed by protein smearing,specifically around the low molecular weight protein bands. The smearing could possibly be due tothe breakdown products and the glycation. There were slight differences between the proteinprofiles under reducing and non-reducing conditions as well. Nevertheless, there was the retentionof a band in the 37kDa molecular weight marker in all 4 samples, likely consistent with heat stabletropomyosin (TM). Mass spectrometry showed allergens that are characterized (Hal d 1 and Hal di1), with 90% of sequence homology with main tropomyosin allergens from seafood.Scientific impact and relevance: The results will highlight effects of food matrix on shellfishallergens digestibility proving its relevancy in molecular allergology. Moreover, an insight will beobtained on the differences in digestibility of allergenic versus non-allergenic tropomyosins in thereal food matrix.

AB  - Objective: to create method for unrestrictive deep, relative quantification of post translationalmodifications (PTMs) within different proteomes. Pollution field studies of bio indicators such aspollen are valuable because of realistic situation of target contamination, however they carry thegreat extent of uncertainty in attributing and delineating the polluting effect from multiple sources.Holistic research platform focusing on comprehensively characterized and quantified PTMs ofcomparable bio-indicator proteomes could help and overcome these obstacles of field pollutionstudies.Material and Methods: Scanning electron and light microscopy assessed surface and sub pollenparticle (SPP) releasing features of timothy grass (TG) pollen. Inductively coupled atomic emissionspectrometry revealed metal elemental content in pollen while in solution trypsin digested pollenproteomes analysed with high resolution Orbitrap mass tandem spectrometry and PEAKS Suite 8.5brought quantitative information on protein expression level and its PTM profiling.Results: TG polluted pollen samples (P2) collected along regional road and chemical plant,exposed to air contaminants from road traffics and chemical plants showed 4.5 times higher SPPreleasing capacity, with notable surface changes, as well as significantly higher contents of Mn, Hgand Cd. Antioxidative enzymes (oxidoreductases, superoxide dismutases and peroxidases),including actin, were upregulated several times in polluted sample compared to ecologicallypreserved pollen (P1). While the level of spontaneous and physiological PTMs includingmethylation, acetylation, deamidation and formylation, was similar without significant changes inP1 and P2 pollens, oxidative PTMs including oxidation of Met, Lys, His, Pro and HNE and hexoseadducts showed several times higher and significant increase in abundancy of P2 compared to P1.PTMs connected to road traffic such as tyrosine nitration were very rare and low abundant.Conclusion: Results suggest prominent role of chemical pollution compared to effect of road trafficpollution, with primary consequences from oxidative properties of mercury (Hg) and cadmium(Cd).

AB  - Major green tea catechin, epigallocatechin-3-gallate (EGCG), binds non-covalently to numerous dietary proteins, including beta-lactoglobulin of cow's milk. The effects of glycation of proteins via Maillard reaction on the binding capacity for polyphenols and the antiradical properties of the formed complexes have not been studied previously. Binding constant of BLG glycated by milk sugar lactose to EGCG was measured by the method of fluorophore quenching. Binding of EGCG was confirmed by CD and FTIR. The antioxidative properties of the complexes were examined by measuring ABTS radical scavenging capacity, superoxide anion scavenging capacity and total reducing power assay. Glycation of BLG does not significantly influence the binding constant of EGCG for the protein. Conformational changes were observed for both native and glycated BLG upon complexation with EGCG. Masking effect of polyphenol complexation on the antioxidative potential of the protein was of the similar degree for both glycated BLG and native BLG.

AB  - Background: Short ragweed (Ambrosia artemisiifolia) allergies affect more than 36 million people annually. Ragweed pollen grains release subpollen particles (SPP) of respirable size upon hydration or a change in air electrical conditions. The aim of this study was to characterize the proteomes and allergomes of short ragweed SPP and total pollen protein extract (TOT), and compare their effects with those of standard aqueous pollen protein extract (APE) using sera from short ragweed pollen-sensitized patients. Methods: Quantitative 2D gel-based and shotgun proteomics, 1D and 2D immunoblotting, and quantitative ELISA were applied. Novel SPP extraction and preparation protocols enabled appropriate sample preparation and further downstream analysis by quantitative proteomics. Results: The SPP fraction contained the highest proportion (94%) of the allergome, with the largest quantities of the minor Amb a 4 and major Amb a 1 allergens, and as unique, NADH dehydrogenases. APE was the richest in Amb a 6, Amb a 5 and Amb a 3, and TOT fraction was the richest in the Amb a 8 allergens (89% and 83% of allergome, respectively). Allergenic potency correlated well among the three fractions tested, with 1D immunoblots demonstrating a slight predominance of IgE reactivity to SPP compared to TOT and APE. However, the strongest IgE binding in ELISA was noted against APE. New allergenic candidates, phosphoglycerate mutase and phosphoglucomutase, were identified in all the three pollen fractions. Enolase, UTP-glucose-1-phosphate uridylyltransferase and polygalacturonase were observed in SPP and TOT fractions as novel allergens of the short ragweed pollen, as previously described. Conclusion and Clinical Relevance: We demonstrated that the complete major (Amb a 1 and 11) and almost all minor (Amb a 3, 4, 5, 6, 8 and 9) short ragweed pollen allergen repertoire as well as NADH oxidases are present in SPP, highlighting an important role for SPP in allergic sensitization to short ragweed.

APE was the richest in Amb a 6, Amb a 5 and Amb a 3, and TOT fraction was the richest in the Amb a 8 allergens (89% and 83% of allergome, respectively). Allergenic potency correlated well among the three fractions tested, with 1D immunoblots demonstrating a slight predominance of IgE reactivity to SPP compared to TOT and APE. However, the strongest IgE binding in ELISA was noted against APE. New allergenic candidates, phosphoglycerate mutase and phosphoglucomutase, were identified in all the three pollen fractions. Enolase, UTP-glucose-1-phosphate uridylyltransferase and polygalacturonase were observed in SPP and TOT fractions as novel allergens of the short ragweed pollen, as previously described. Conclusion and Clinical Relevance: We demonstrated that the complete major (Amb a 1 and 11) and almost all minor (Amb a 3, 4, 5, 6, 8 and 9) short ragweed pollen allergen repertoire as well as NADH oxidases are present in SPP, highlighting an important role for SPP in allergic sensitization to short ragweed.",

AB  - Bovine alpha-lactalbumin (ALA) is an important Ca-binding protein of milk. Epigallocatechin-3-gallate (EGCG) is the major and the most biologically active catechin of green tea, which has the highest binding affinity to whey proteins due to galloyl functional group. In this study experimental and computational methods were used to investigate noncovalent interactions of EGCG and ALA. Binding affinity of EGCG for ALA, determined by fluorescence quenching analysis, was in the range described for complexes of EGCG and other dietary proteins, and lower than affinity of some phenolic compounds to ALA. Based on circular dichroism and Fourier transform infrared spectroscopy spectra, binding of EGCG change ALA conformation inducing alpha-helix to beta-structures transition. The isothermal titration calorimetry results suggest that the binding of EGCG to ALA is enthalpically favorable. The docking analysis shows that EGCG binds in the hydrophobic pocket at the entrance of cleft between alpha-helical and beta-sheetrich domains and includes residues of aromatic cluster II. Uptake of ALA by monocytes proceeds at a slower rate in the presence of EGCG suggesting that EGCG binding may impair uptake of ALA by antigen-presenting cells. ALA, being of low cost and widely available protein, can serve as suitable delivery system for EGCG, as well as for food fortification with this bioactive catechin. (C) 2016 Elsevier Ltd.

AB  - Modified allergens are a safer and more efficient alternative to natural allergens for specific immunotherapy. As the modification of an allergen can diminish its immunogenicity due to the alteration of T-cell epitopes, in this paper we study the effects of a reversible chemical modification of Art v 1, the main allergen of mugwort pollen, on its allergenicity and immunogenicity. Modification of Art v 1 by cis-aconitylation into a polyanionic derivative (CAA) did not result in any significant structural alteration. However, IgE-binding epitopes on CAA were blocked, resulting in a reduced IgE-binding and basophil activation. Both proteins induced proliferation of CD3(+)CD4(+) T-cells in mugwort-allergic patients, but only unmodified allergens increased IL-4, IL-5 and IL-10 production. Rabbit and mouse anti-CAA antibodies exhibited cross-reactivity with native allergens and blocked human IgE-binding to Art v 1. Degradation of CAA by lysosomal fraction enzymes resulted in a similar set of peptides, harboring MHC class II-binding peptides, as unmodified proteins. Thus, cis-aconitylation modified Art v 1 had a significantly reduced allergenicity, whereas its immunogenicity was completely preserved. Acid-environment-responsive modification, which releases a full repertoire of native allergen epitopes within a particular site, can be considered a smart drug delivery system, which is able to deliver a therapeutically-effective dose in a controlled manner, and minimizes adverse side effects.

AB  - Phenolic composition of Ambrosia artemisiifolia L. pollen and sub-pollen particles (SPP) aqueous extracts was determined, using a novel extraction procedure. Total phenolic and flavonoid content was determined, as well as the antioxidative properties of the extract. Main components of water-soluble pollen phenolics are monoglycosides and malonyl-mono- and diglycosides of isorhamnetin, quercetin and kaempferol, while spermidine derivatives were identified as the dominant polyamides. SPP are similar in composition to pollen phenolics (predominant isorhamnetin and quercetin monoglycosides), but lacking small phenolic molecules ( lt 450 Da). Ethanol-based extraction protocol revealed one-third lower amount of total phenolics in SPP than in pollen. For the first time in any pollen species, SPP and pollen phenolic compositions were compared in detail, with an UHPLC/ESI-LTQ-Orbitrap-MS-MS approach, revealing the presence of spermidine derivatives in both SPP and pollen, not previously reported in Ambrosia species.

AB  - Sonication is a new processing technology in the dairy industry. The aim of this study was to test glycation of beta-lactoglobulin (BLG) in Maillard reaction (MR) induced by high-intensity ultrasound in aqueous solution under neutral conditions at 10-15 degrees C, which is not favourable for the MR. BLG was sonicated in the presence of glucose, galactose, lactose, fructose, ribose and arabinose. Formation of Maillard reaction products (MRPs) was monitored by mass spectrometry, spectrophotometry and fluorimetry. Ultrasound treatment resulted in formation of MRPs with all tested carbohydrates. Ribose induced the highest degree of modification resulting in 76% of BLG modified and an average of three anhydroribose units attached. Circular dichroism spectra analyses indicated only minor alterations in secondary and tertiary structures. MRP obtained by ultrasound exhibited 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and possessed increased iron-chelating activity and reducing power. High-intensity ultrasound efficiently promotes BLG-glycoconjugates formation by MR in aqueous solutions under non-denaturing conditions.

AB  - Non-covalent interactions between beta-lactoglobulin (BLG) and polyphenol extracts of teas, coffee and cocoa were studied by fluorescence and CD spectroscopy at pH values of the gastrointestinal tract (GIT). The biological implications of non-covalent binding of polyphenols to BLG were investigated by in vitro pepsin and pancreatin digestibility assay and ABTS radical scavenging activity of complexes formed. The polyphenol-BLG systems were stable at pH values of the GIT. The most profound effect of pH on binding affinity was observed for polyphenol extracts rich in phenolic acids. Stronger non-covalent interactions delayed pepsin and pancreatin digestion of BLG and induced beta-sheet to alpha-helix transition at neutral pH. All polyphenols tested protected protein secondary structure at an extremely acidic pH of 1.2. A positive correlation was found between the strength of protein-polyphenol interactions and (a) half time of protein decay in gastric conditions (R-2 = 0.85), (b) masking of total antioxidant capacity of protein-polyphenol complexes (R-2 = 0.95).

AB  - Plant proteinase inhibitors are considered important defense molecules against insect and pathogen attack. The cysteine proteinase inhibitor (CPI) from green kiwifruit (Actinidia deliciosa) belongs to the cystatin family and shows potent antifungal activity (in vitro and in vivo). However, the low abundance of this molecule in fruit (6 μg/g of fresh fruit) seems to limit further investigations on the interaction between phytocystatin and photopathogenic fungi. In this paper the cDNA of the kiwi CPI was expressed in Escherichia coli. Fifteen N-terminal amino acids were identified by Edman degradation, and 77% of the rCPI primary structure was confirmed by mass fingerprint. The structural homology of recombinant CPI (rCPI) to its natural counterpart has been clearly demonstrated in immunological assays (immunoblot and ELISA inhibition). Biological activity of rCPI was demonstrated in inhibition assay with cysteine proteinase papain (EC50 2.78 nM). In addition, rCPI reveals antifungal properties toward pathogenic fungi (Alternaria radicina and Botrytis cinerea), which designates it as an interesting model protein for the exploration of plant phytocystatins - pathogen interactions. Understanding the molecular mechanisms of natural plant resistance could lead to the development of ecologically safe fungicides for controlling postharvest diseases and maintaining food quality.

AB  - Canine atopic dermatitis (CAD) is an immune system disorder that affects 10-15% of the canine population. Short ragweed (Ambrosia artemisiifolia) pollen represents one of the major seasonal sources of allergenic pollen proteins in Europe, particularly in the Pannonian valley of the Balkan region. In Serbia, about 66% of atopic dogs showed a positive intradermal skin test with its pollen extract, which is second to house dust mites. Therefore, characterization of Ambrosia artemisiifolia pollen components, in terms of defining major and minor allergens that induce clinically manifested allergic reaction in dogs, is important for valid diagnosis and efficient therapy. This study has, for the first time, characterized and identified major Ambrosia artemisiifolia allergens in CAD, using an immunoproteomic approach. To assess the prevalence of specific IgE in electrophoretically separated ragweed pollen proteins, individual reactivity of sera from dogs with CAD was analyzed and compared to the reactivity of sera from healthy dogs in the non-reducing conditions, which were found optimal for specific canine IgE detection. A specific IgE band (38 kDa) was recognized as the most dominant allergen in CAD, occurring in 81% of positive dog's sera. 2-D immunoblotting followed by a mass spectrometry peptide fingerprint analyses with pooled canine and human atopic sera, revealed that 38 kDa major Ambrosia atremisiifolia allergens in CAD were all five isoallergens of the Amb a 1 group (antigen E), including the previously named Amb a 2 (antigen K). In contrast to canine sera, human atopic sera also recognized lower mass allergens such as the 13 fragment of Amb a 1 and profilins (Amb a 8 variants). The most prominent ragweed proteins in CAD, represent, as in humans, variants of all five isoallergens of the Amb a 1 group (pectate lyase): Amb a 1.0101 and its natural variant E1XUL2, Amb a 1.0202, 1.0304, 1.0402 and the natural variant of Amb a 1.0501, E1XUM0, as well as the a fragment of pollen allergen Amb a 1.0201.

AB  - The in vitro gastric digestion of several food allergens (beta-lactoglobulin (BLG), alpha-lactalbumin (LA) and peanut allergens (PE)) in the presence of a catechin-enriched polyphenol extract of green tea (GTC), oxidized polyphenols and phenol oxidase processed food allergens and GTC was investigated. Pepsin-resistant proteins, such as BLG, major peanut allergens, Ara h 1 and Ara h 2, degrade faster in the presence of catechin-enriched green tea polyphenols. Phenol oxidase polymerized GTC affected adversely protein digestion of BLG and LA, but not digestion of PE proteins. Protecting effect of polyphenols correlated well with the ability of proteins to form insoluble complexes with oxidized catechins. Cross-linking of proteins and polyphenols further extended the half-lives of BLG and LA in the in vitro digestion by pepsin. Catechin-enriched green tea polyphenols of food supplements facilitate pepsin digestion of major food allergens, but hamper their digestion if oxidized and polymerized by phenol oxidase.

AB  - BACKGROUND: The major whey protein beta-lactoglobulin (BLG) has been widely studied for its functional properties. The aim of this study was to develop an efficient, inexpensive and rapid one-step method for the isolation and purification of BLG while preserving its native structure. RESULTS: BLGwas purified fromdefattedwheyobtainedfromrawcow's milkbyanionexchangechromatography. Protein purity and identitywere determined using reverse phase high-performance liquid chromatography andmass spectrometry. Total BLG yield was 80% with protein purity from 97 to 99%. BLG isoforms A and B were separated into fractions of 91 and 99% purity respectively. The structure and native conformation of the isolated BLGwere compared with those of standard commercial BLG by circular dichroism spectrometry, susceptibility to various crosslinking enzymes and enzyme-linked immunosorbent assay inhibition. CONCLUSION: Theproposedmethodis veryuseful for the rapid preparationofBLGsuitable for studying antigenicandmolecular characteristics of this protein, aswell as the effect of food processing on these properties. The procedure requires only 1 day for the purification of about 300 mgof BLG from a single run using a small column (2.5 cmx20 cm) of diethylaminoethyl Sephadex and has potential for scaling up.

BLG isoforms A and B were separated into fractions of 91 and 99% purity respectively. The structure and native conformation of the isolated BLGwere compared with those of standard commercial BLG by circular dichroism spectrometry, susceptibility to various crosslinking enzymes and enzyme-linked immunosorbent assay inhibition. CONCLUSION: Theproposedmethodis veryuseful for the rapid preparationofBLGsuitable for studying antigenicandmolecular characteristics of this protein, aswell as the effect of food processing on these properties. The procedure requires only 1 day for the purification of about 300 mgof BLG from a single run using a small column (2.5 cmx20 cm) of diethylaminoethyl Sephadex and has potential for scaling up.
