Abstract

Complement activation unleashes powerful effector mechanisms against which host cells are protected by homologous restriction factors. These factors are glycolipid-anchored membrane proteins that either induce C3 convertase dissociation (for example decay-accelerating factor) or prevent the full development of the membrane attack complex (for example homologous restriction factor and CD59). In this article Peter Lachmann explores the biology and biochemistry o f these important and intriguing molecules.

      Complement activation, physiologically triggered in circumstances where the innate immune system senses ‘foreign invasion’ or ‘self-injury,’ is regulated by negative feedback mechanisms to avoid over-activation and collateral damage to healthy host tissues.19 This is achieved by the expression of several ‘protective’ complement pathway regulatory proteins (CPRPs) on the vascular endothelial cells,20 for example, decay accelerating factor (CD55); membrane cofactor protein (CD46), and membrane-attack-complex-inhibitory protein (CD59). CPRPs are relatively species-specific,21 and pig CPRPs are less effective in controlling human complement-mediated injury than are human CPRPs.

      Why AMD, a slow disease that progresses over life time, is so strongly defined by polymorphisms in the innate immune system, a system that has been historically linked with a very fast and direct activation, and why those changes increase disease risk in the eye, remains currently unresolved but might be linked to the particular characteristics of the eye. CD59, also called membrane inhibitor of reactive lysis or protectin, is a glycosylphosphatidylinositol (GPI) anchored membrane-bound protein (Kieffer et al., 1994) that protects host tissue by blocking the assembly of the membrane-attack complex through binding to C9, thus inhibiting its integration into the C5b-9 complex (Lachmann, 1991). In human, it is widely expressed on cells of all tissues (Meri et al., 1991).

      Because vRCAs display both DAA (for CP and AP C3 convertases) and CFA (for C3b and C4b), it became apparent from the deletion and swapping studies that CCP modules 1–2 are critical for the DAA and CCP modules 2–3 are critical for the CFA. Similarly, ‘homologous restriction’ or functioning of hRCAs in a species-specific manner has been known for a long time (Lachmann, 1991; Zipfel and Skerka, 2009) but the molecular basis for this phenomenon was not identified. Characterization of species specificity determinants in SPICE and VCP revealed that a simple charge reversal in the central modules can result in switch of RCA specificity (Yadav et al., 2012).
