Аннотация
Экзосомы и микровезикулы, совместно называемые малые экстраклеточные везикулы (мЭВ), представляют собой везикулы со средним размером около 100-150 нм. В настоящее время активно исследуется роль мЭВ в самых разных аспектах сигналинга в организме, кроме того, часто мЭВ могут служить маркерами разных патологий. Продолжается активное изучение состава мЭВ. В данной работе мы показали, что в мЭВ можно определить концентрацию холестерина и триглицеридов с помощью коммерческих наборов, предназначенных для сыворотки крови. Методика была опробована на мЭВ из крови пациентов с диагнозом депрессия и на здоровых добровольцах. Различий в концентрации холестерина и триглицеридов в мЭВ из сыворотки крови пациентов с депрессией и контрольной группы найдено не было. Концентрация холестерина и триглицеридов в образцах в несколько раз превосходит порог чувствительности методов, установленный производителем наборов.
