WebMar 13, 2024 · In the case of LP, MASP-1 auto-activates “on site”, when its associated collectin pattern recognition molecule (PRM) binds to a target surface; activated MASP-1 will then activate MASP-2. The CP pathway proceeds quite similarly, with a first step of C1r auto-activation and C1s activation by activated C1r in a second step. WebMay 30, 2024 · Significance. IgM antibodies protect mammals against humoral microbial infection and mediate clearance of cellular debris. IgM activates the immune complement system only after binding to cell-surface antigens.
