ORIGINAL ARTICLE: Cell‐Surface CD200 May Predict Efficacy of Paternal Mononuclear Leukocyte Immunotherapy in Treatment of Human Recurrent Pregnancy Loss

Abstract: The number of CD200(+) paternal mononuclear leukocytes may be an important determinant of subsequent reproductive outcome in a subset of patients. A lower % CD200(+) cell number may also reflect hitherto unappreciated paternal factors bearing on reproductive success. It is feasible to recruit women to enter observational studies and to obtain useful data as a foundation for further studies. More complete patient characterization in a larger study is needed.

“…Though none of these approaches have shown benefit overall, [17][18][19] some investigators are still attempting to identify a target, approach or clinical subgroup that may benefit from immunomodulatory therapy. 20,21 In normal pregnancy, one of the ways in which maternalfetal interaction occurs is through the exchange of cells. Maternal-fetal exchange results in microchimerism, defined as small amounts of foreign cells or DNA detectable in a genetically distinct individual.…”

“…This complicates the sufficient pre-implantation microenvironment which influences the survival of trophoblastic cells and modifies the maternal Treg/T ratio of effector lymphocytes in favor of maternal tolerance. Transfused host leukocytes induced activity of TGF-B suppressor cells, and the surface molecule of CD200 cell that signals the tolerance of mononuclear dendritic cells involved in this discovered effect (11). In fact, the number of CD200 cells granted, were considerably higher in women who achieved gestation and the same was observed in women who achieved a live birth.…”

“…Большинство авторов подчеркивают высокую эффективность АИЛ в лечение ПНБ [9,13,15,16,19,23,29]. В то же время в ряде исследований не выявлено достоверного увеличения числа ро-дов на фоне АИЛ [30,37].…”

“…В целом причина данных разночтений объясняется, по-видимому, исполь-зованием различных протоколов и принципов отбора пациентов [26]. Причиной недостаточной эффективности АИЛ может быть также исполь-зование в некоторых исследованиях криоконсер-вированных лимфоцитов, отличающихся низкой экспрессией толерогенных молекул CD200 в свя-зи с процедурой замораживания и разморажива-ния клеток [9]. Проведенные нами ранее исследования, на-правленные на поиск биомаркеров, ассоцииро-ванных с бесплодием неясного генеза, проде-монстрировали, что среди ряда параметров (ответ в СКЛ, активность БФ, оценка активированных НК клеток, Treg и цитокинового баланса), дефи-цит БФ являлся наиболее частым нарушением, выявляемым у преобладающего большинства женщин как при вторичном, так и при первич-ном бесплодии.…”
