Роль регуляторных Т-клеток в системном воспалительном ответе
Системный воспалительный ответ - сложный мультисиндромный, фазоспецифичный патологический процесс, развивающийся при системном повреждении. Исход во многом зависит от баланса разнонаправленных последовательных стадий: гипервоспалительной реакции и компенсаторного антивоспалительного механизма. Регуляторные T-клетки (Tregs) способны ограничивать адаптивные и врожденные иммунные реакции и вносить свой вклад в различные этапы системного воспалительного ответа. На начальной гипервоспалительной стадии Tregs способны ограничивать аутогенное повреждение. Однако в последующем Tregs способствуют развитию компенсаторного антивоспалительного механизма и формированию индуцированной иммуносупрессии, которая предрасполагает к высокой восприимчивости к нозокомиальным и оппортунистическим инфекциям с последующим переходом в полиорганную недостаточность. Регуляторные Т-клетки и их функциональные изменения рассматриваются как диагностические и прогностические маркеры осложнений системного воспалительного ответа.
