The Sez6 Family Inhibits Complement by Facilitating Factor I Cleavage of C3b and Accelerating the Decay of C3 Convertases

Frontiers in Immunology, 2021
The Sez6 family consists of Sez6, Sez6L, and Sez6L2. Its members are expressed throughout the brain and have been shown to influence synapse numbers and dendritic morphology. They are also linked to various neurological and psychiatric disorders.

The Complement System and ANCA Associated Vasculitis in the Era of Anti-Complement Drugs

Frontiers in Immunology, 2022
ANCA (anti-neutrophil cytoplasmic antibody)-associated vasculitis (AAV) is the condition in which ANCA, as an autoantibody, is associated with the pathogenesis of vasculitis in small blood vessels, mainly in the ear, nose, throat, kidney, lung, and ...

The contribution of the alternative pathway in complement activation on cell surfaces depends on the strength of classical pathway initiation [PDF]

, 2023
OBJECTIVES: The complement system is an important component of innate immunity. The alternative pathway (AP) amplification loop is considered an essential feed forward mechanism for complement activation. However, the role of the AP in classical pathway (

COMPLEMENT-MEDIATED ADIPOCYTE LYSIS BY NEPHRITIC FACTOR SERA [PDF]

, 1993
Recent data indicate a previously unsuspected link between the complement system and adipocyte biology. Murine adipocytes produce key components of the alternative pathway of complement and are able to activate this pathway.

Biochemical and functional studies of a novel complement inhibitor, CRIT, with its interaction partners [PDF]

, 2005
Complement C2 receptor trispanning (CRIT), a three transmembrane receptor, was first discovered on the surface of the parasite Schistosoma haematobium and formerly termed Schistosoma trispanning orphan receptor (Sh-TOR). This receptor acts as decoy C2-
