AB  - Novel allergen immunotherapy (AIT) approaches necessitate the use of more effective and safe therapeutics, which can be accomplished by employing novel adjuvants for improved innate immune cell activation, as well as hypoallergenic allergen forms. In this study, we investigate the immunomodulatory effects of a chimera rBet v 1a-BanLecwt (rBv1a-BLwt; Cwt) composed of the major birch pollen allergen Bet v 1a and banana lectin (BanLecwt; BLwt) and two novel chimeras, rBv1l-BLH84T (rBet v 1l-BanLecH84T; C1) and rBLH84T-Bv1l (rBanLecH84T-Bet v 1l; C2), both composed of BLH84T and hypoallergenic birch pollen allergen Bv1l in the co-culture model Caco-2/THP-1, and PBMCs from donors with birch pollen allergy. The chimeric molecules rBv1l-BLH84T (C1) and rBLH84T-Bv1l (C2) were created in silico and then produced in E. coli using recombinant DNA technology. Real-time PCR analysis of gene expression following compound treatment in the co-culture model revealed that all three chimeras have the potential to induce the anti-inflammatory cytokine IL-10 gene expression in Caco-2 cells and IFN-γ gene expression in THP-1 cells. Sandwich ELISA revealed that Cwt increased IL-10 secretion and IFN-/IL-4 levels in PBMCs from birch pollen allergic donors, whereas C1 and C2 were less effective. The findings suggest that Cwt should be analyzed further due to its potential benefit in AIT.

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  - Common ragweed (Ambrosia atremisiifolia) is one of the most frequent causes of pollen-induced allergic reactions both in humans and dogs. It has not been defined yet, what is the major allergen(s) to which most dogs allergic to ragweed show a positive result on intradermal skin test (IDST). In the present study sensitization to Ambrosia artemisiifolia pollen allergens in dogs with atopic dermatitis was examined with both in vivo and in vitro tests, including IDST and serum allergen specific IgE test. Detection of specific-IgE antibodies against ragweed allergens by immunoblotting in the sera of allergic dogs was optimized, as well. Dogs that were positive, as judged by IDST reactions to ragweed pollen allergens, also had alergen specific IgE antibodies in their sera. Results indicate that major allergens of A. artemisifolia pollen in dogs are Amb a 1 and Amb a 2. Further characterization of ragweed allergens is needed before they could potentially be used in intradermal testing or allergen immunotherapy in affected dogs. Also, we evaluated new Favrots diagnostic criteria for canine atopic dermatitis in dogs allergic to Ambrosia atremisiifolia pollen. It might be concluded that proposed criteria are of great assistance for seting up suspected diagnosis of canine atopic dermatitis, after ruling out other pruritic dermatoses.

AB  - Introduction. In spite of the wide usage of corticosteroids for the treatment of a plethora of diseases, sometimes they can induce immediate hypersensitivity reactions, which are however uncommon. Case Outline. We report a case of immediate allergic reaction induced by intravenous methylprednisolone given before operation for surgical repair of an arm contracture as a sequel of burns, which the child had tolerated a month before. Six weeks later the patient repeated the anaphylactic reaction during skin testing to methylprednisolone. In addition, basophile activation test with methylprednisolone (BAT) was positive. Conclusion. This case report describes a patient who experienced intraoperative anaphylaxis and anaphylactic reaction induced by skin testing. This is the first report on induction of both anaphylactic reactions by methylprednisolone in the same child. Clinical findings, positive BAT and positive skin tests with methylprednisolone imply that the child developed type-I hypersensitivity. The lack of cross-reactivity with other corticosteroids emphasizes that the reactions were caused by the steroid molecule.
AB  - Uvod. Uprkos širokoj primeni kortikosteroida u lečenju od različitih bolesti, oni ponekad mogu izazvati ranu alergijsku reakciju. Prikaz bolesnika. Kod dvanaestogodišnjeg dečaka došlo je do rane alergijske reakcije izazvane intravenskom primenom metilprednizolona neposredno pre hirurške intervencije, tačnije, korekcije kontrakture šake koja se javila kao komplikacija opekotine. Mesec dana pre pojave alergijske reakcije dete je primalo metilprednizolon i dobro ga podnosilo. Šest nedelja posle operacije ponovo se javila anafilaktička reakcija tokom kožnog testiranja metilprednizolonom. Primenjen je i test aktivacije bazofila (BAT) ovim lekom, čiji je nalaz bio pozitivan. Zaključak. Ovo je prvi prikaz dve vrste anafilaktičke reakcije izazvane metilprednizolonom kod iste osobe. Klinička slika, pozitivni nalaz BAT i pozitivne kožne probe na metilprednizolon pokazuju da se kod deteta razvio prvi tip hipersenzitivne reakcije. Nedostatak unakrsne reaktivnosti s ostalim kortikosteroidima ukazuje na to da je alergijska reakcija izazvana steroidnim molekulom.
