[греч. kytos — сосуд, здесь — клетка, lysis — разложение, распад, растворение и лат. - in(e) — суффикс, обозначающий "подобный"]1) вещества, вызывающие цитолиз (см. цитолиз);2) антитела (см. антитела), вызывающие растворение различных клеток организма (эритроцитов — гемолизины, лейкоцитов — лейколизины, сперматозоидов — сперматолизины и т.д.) и бактерий (бактериолизины). Действие Ц. связано с частичным разрушением клеточной мембраны и выходом содержимого клетки в окружающую среду. Цитолитическое действие Ц. проявляется только в присутствии комплемента. Ц. впервые обнаружены в 1898 г. Ж. Борде в сыворотках животных после повторных введений им чужеродных эритроцитов. Ц. человека относятся к иммуноглобулинам классов М (IgM) и G (IgG2 и IgG3).Толковый биотехнологический словарь. Русско-английский. > цитолизины
