У женщин с ановуляторным синдромом и нарушением репродуктивной функции персистирующая ациклическая гипоэстрогенемия и недостаточность прогестерона связаны с нарушением морфологической структуры эндометрия, повышенной экспрессией рецепторов эстрогенов, прогестерона, перераспределением NK-клеток с преобладанием CD16+NK-клеток в эндометрии, при этом сниженное количество CD16+NK-клеток и цитотоксических CD8+Т-лимфоцитов в крови сочеталось с повышением уровнем IFNγ в сыворотке и увеличением спонтанной продукции TNFα.</p></abstract><trans-abstract xml:lang="en"><p>Abstract. Persisting acyclic hypoestrogenemia and progesterone insufficiency in the women with anovulatory syndrome and altered reproductive functions are associated with disturbed endometrial morphology, increased expression of receptors for estrogenes, progesterone, redistribution of NK cells with predominance of CD16+NK cells in endometrium. Meanwhile, decreased number of CD16+ NK cells and cytotoxic CD8+ T cells in blood was accompanied by increased serum IFNγ levels, and enhanced spontaneous production of TNFα. (Med.
