Demonstration of the ability of native products of lactobacteria to bind mannose containing N-glycans as a display of one of the mechanisms of probiotic behavior of these symbiont microorganism in gastrointestinal tract (GIT). Materials and methods. Lactobacillus plantarum 30 grown on selective medium (MRS-agar) and their ultrasound lysates were used in the study. Standard technique ofdelayed type hypersensitivity (DTH) reaction was used with inactivated Listeria monocytogenes culture as a priming agent. Results. DTH reaction in vivo has demonstrated that oligomannoside N-glycan of egg albumin is a general acceptor for adhesins that are present in the native preparations ofcertain L.plantarum strains, as well as for phosprenyl (PHP) immunomodulator - an inhibitor of cell IL-2 reception. Conclusion. The data obtained give evidence that mannose specific adhesins that are conserved in lactobacteria preparations have the same binding sites in egg albumin as PHP and, therefore, IL-2.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Демонстрация способности нативных продуктов лактобактерий связывать маннозосодержащие N-гликаны как проявление одного из механизмов пробиотического поведения этих микроорганизмов-симбионтов в желудочнокишечном тракте (ЖКТ). Материалы и методы. В работе использованы бактерии Lactobacillus plantarum 30, выращенные на селективной среде (MRS-агар) и их ультразвуковые лизаты. Постановку реакции гиперчувствительности замедленного типа (ГЗТ) проводили по стандартной методике с использованием в качестве примирующего антигена инактивированную культуру Listeria monocytogenes. Результаты. С помощью реакции ГЗТ in vivo показано, что олигоманнозид N-гли-кан яичного альбумина служит общим акцептором для адгезинов, присутствующих в нативных препаратах определенных штаммов L. plantarum, а также для иммуномодулятора фоспренил (ФП) - ингибитора клеточной рецепции ИЛ-2. Заключение. Полученные данные свидетельствуют, что сохраняющиеся в препаратах лактобактерий маннозоспецифические адгезины имеют в яичном альбумине те же сайты связывания, что и ФП, а следовательно, и ИЛ-2.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Lactobacillus plantarum</kwd><kwd>Lactobacillus plantarum</kwd><kwd>phosprenyl</kwd><kwd>delayed type hypersensitivity</kwd><kwd>IL-2</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фоспренил</kwd><kwd>гиперчувствительность замедленного типа</kwd><kwd>ИЛ-2</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Николаева Т.Н., Зорина В.В., Бондаренко В.М.
