Scheme of the complement system. The complement system, also known as complement cascade, is a part of the humoral, innate immune system and enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.

Two studies, conducted in the four European Union countries, involving 2,000 participants (1,000 men and 1 000 women) concluded that females are 74 - 92% as strong as males, as many women (211 of 1,000) are still physically stronger than average men. [29] [30] The differences is smaller in lower body strength and higher in upper body strength. [27]
H. Harris, publishing in the British Journal of Dermatology in 1947, wrote Native Americans have the least body hair, Han Chinese people and black people have little body hair, white people have more body hair than black people and Ainu have the most body hair. [18] Anthropologist Arnold Henry Savage Landor described the Ainu as having hairy ...
The protein encoded by this gene is a type I membrane protein and is a regulatory part of the complement system. The encoded protein has cofactor activity for inactivation (through cleavage) of complement components C3b and C4b by serum factor I, which protects the host cell from damage by complement. [8]
Three biochemical pathways activate the complement system: the classical complement pathway, the alternate complement pathway, and the mannose-binding lectin pathway. [9] These processes differ only in the process of activating C3 convertase, [10] which is the initial step of complement activation, and the subsequent process are eventually the ...
The classical complement pathway is one of three pathways which activate the complement system, which is part of the immune system. The classical complement pathway is initiated by antigen-antibody complexes with the antibody isotypes IgG and IgM .

The complement system is tightly regulated by a network of proteins known as "regulators of complement activation (RCA)" that help distinguish target cells as "self" or "non-self." A subset of this family of proteins, complement control proteins (CCP), are characterized by domains of conserved repeats that direct interaction with components of ...
