Complement system - Alternative pathway · Step 1: Activation of C3(H2O) and factorB (C3(H2O)+B complex) by binding of non-specific activators like endotoxins,

1 Nov 2018 Complement system is an important component of innate immunity and can be activated through the classical, alternative, and lectin pathways.

Factor B then combines with the cell -bound C3b to form C3bB. Factor D then splits the bound Factor B into Bb and Ba, forming C3bBb . Absent complement alternative pathway (AH50) in the presence of a normal total hemolytic complement (CH50) suggests an alternative pathway component deficiency. Normal AH50 with absent CH50 suggests an early (C1, C2, C4) classic pathway deficiency. Absent AH50 and CH50 suggests a late (C3, C5, C6, C7, C8, C9) component deficiency or complement 2016-03-31 The complement system can be activated through three pathways: the classical pathway, the alternative pathway, and the lectin pathway.

Key Points • Immune-complex kidney disease in systemic lupus erythematosus (SLE) is associated with activation of the classical, lectin, and alternative complement pathways This pathway involves complement components C1, C2 and C4. The pathway is triggered by antibody-antigen complexes binding to C1, which itself has three subcomponents C1q, C1r and C1s. C3 is the main component of the whole complement system. It can be activated by all the complement pathways (classical, lectin, and alternative). Spontaneous activation of C3 can occur by hydrolysis of C3 that disrupts an internal thioester bond (to generate C3 (H 2 O)) and changes the conformation of C3 so that it can bind factor B. The alternative pathway of compliment is activated by LPS and other lipopolysaccharides found on the surface of invading pathogens. The alternative pathways always active at a very low level.

AH50 : Complement proteins are components of the innate immune system. There are 3 pathways to complement activation: (1) the classical pathway, (2) the alternative (or properdin) pathway, and (3) the lectin (or mannose-binding lectin, MBL) pathway.
