ЧТО ОЗНАЧАЕТ СЛОВО OPSONIN
опсонин
Опсонин - любая молекула, которая усиливает фагоцитоз, отмечая антиген иммунного ответа. Однако этот термин обычно используется в отношении молекул, которые действуют как усилитель связывания для процесса фагоцитоза, особенно антител, которые покрывают отрицательно заряженные молекулы на мембране. Молекулы, которые активируют систему комплемента, также считаются опсонинами. Фагоцитарные клетки не имеют рецептора Fc для IgM, что делает IgM неэффективным в содействии фагоцитозу. Однако IgM чрезвычайно эффективен при активации комплемента и поэтому считается опсонином. Опсонины могут также относиться к молекулам, которые нацелены на клетку для разрушения посредством действия естественных киллерных клеток.
