Factor H Autoantibodies and Complement-Mediated Diseases [PDF]

open access: yesFrontiers in Immunology, 2020
Factor H (FH), a member of the regulators-of-complement-activation (RCA) family of proteins, circulates in human plasma at concentrations of 180–420 mg/L where it controls the alternative pathway (AP) of complement in the fluid phase and on cell surfaces.

Hijacking Factor H for Complement Immune Evasion [PDF]

open access: yesFrontiers in Immunology, 2021
The complement system is an essential player in innate and adaptive immunity. It consists of three pathways (alternative, classical, and lectin) that initiate either spontaneously (alternative) or in response to danger (all pathways). Complement leads to
