Component of the membrane attack complex which groups the complement plasma glycoproteins C5b, C6, C7, C8 and polymeric C9 on biological membranes. The complex forms transmembrane channels which displace lipid molecules and other constituents, thus disrupting the phospholipid bilayer of target cells leading to cell lysis by osmotic leakage.

Occurrence of peripheral blood leukocytes from patients with systemic lupus erythematosus. Arthritis Rheum 21: 177 A set of proteins in the complement system that lyses invading bacteria by producing lesions in their cell membranes. The membrane-attack complex formed by complement activation can lyse gram-negative bacteria, parasites, viruses, erythrocytes, and nucleated cells.

However, it is not known whether the administration of eculizumab in pregnant patients with end-stage renal disease due to aHUS may cause reduced membrane-attack-complex formation also in the fetal circulation.

Synonyms: MAC (initialism), terminal complement Choriocapillaris Loss in Advanced Age-Related Macular Degeneration Following the complement cascade, C5b with C6-C9 forms the " membrane attack complex " (MAC), capable of lysing infected cells and pathogens [17, 18].

A membrane attack complex attached to a pathogenic cell The membrane attack complex ( MAC ) or terminal complement complex ( TCC ) is a complex of proteins typically formed on the surface of pathogen cell membranes as a result of the activation of the host's complement system , and as such is an effector of the immune system .

Here, we show that anti-PEG IgG and IgM antibodies bind to PEG molecules on the surface of PEG-coated liposomal doxorubicin (Doxil, Doxisome, LC-101, and Lipo-Dox), resulting in complement activation, formation of the membrane attack complex (C5b-9) in the liposomal membrane, and rapid release of encapsulated doxorubicin from the liposomes.

C5b initiates the membrane attack pathway, which results in the membrane attack complex (MAC), consisting of C5b, C6, C7, C8, and polymeric C9. Complement system - Wikipedia The complement system is part of the innate immune system and has a variety of functions, from destroying invading microorganisms by opsonization to direct destabilization by the membrane attack complex.
