Работа выполнена на крысах линии Вистар, которым один раз в сутки ректально вводили коктейль бактериофагов против патогенных бактерий (основная группа, n=6) или стерильный физиологический раствор (контрольная группа, n=6). Через 10 сут животных выводили из эксперимента, различные участки тонкой кишки замораживали на сухом льду и готовили криостатные срезы для иммуногистохимического выявления локализации А-син в клетках стенки кишечника. В предварительно отобранных пробах крови животных определяли концентрацию А-син в плазме при помощи иммуноферментного метода.</p></sec><sec><title>Результаты</title><p>Результаты. Иммунопозитивные к А-син лимфоциты локализовались в собственной пластинке слизистой оболочки и подслизистой основе. Их общая численная плотность на стандартной площадке в подвздошной кишке достоверно превышала таковую в дистальном отделе тощей кишки. Через 10 сут ректального введения бактериофагов во всех изученных отделах тонкой кишки обнаруживалось достоверное количественное увеличение лимфоцитов, иммунопозитивных к А-син, и усиление экспрессии этого белка в нейронах межмышечных и подслизистых нервных сплетений. Измерение уровня А-син в плазме крови крыс экспериментальной группы показало достоверное увеличение концентрации этого белка относительно контроля.</p></sec><sec><title>Выводы</title><p>Выводы. Бактериофагальное инфицирование микробиоты оказывает выраженное стимулирующее влияние на содержание А-син в нейронах, локализованных в нервных сплетениях стенки тонкой кишки и увеличивает количество инфильтрирующих слизистую оболочку лимфоцитов экспрессирующих А-син. Более высокие уровни А-син в плазме крови животных экспериментальной группы могут быть следствием его повышенной продукции в стенке кишечника как лимфоцитами, так и нейронами ЭНС в условиях повышения кишечной проницаемости, вызванной дисбалансом микробиоты.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to identify the effect of bacteriophage microbiota infection on the expression of alpha-synuclein (A-syn) in rat small intestinal wall cells.</p><sec><title>Material and methods</title><p>Material and methods.
