Complement Anaphylatoxins (C5a, C3a, C4a)

The video tutorial explains the three pathways of complement activation, focusing on the role of C3 convertase in the lectin and classical pathways. It highlights the importance of anaphylatoxins, particularly C3A and C5A, in promoting inflammation, chemotaxis, and phagocytosis. The tutorial also covers how these components enhance the immune response by guiding white blood cells to infection sites and facilitating mast cell degranulation, which releases histamine to increase blood flow and vascular permeability.
