Complement activation in bullous skin diseases.
Pemphigus, bullous pemphigoid, cicatricial pemphigoid, dermatitis herpetiformis, and herpes gestationis are members of the chronic vesiculobullous skin diseases of man. The complement system, including both the classical and alternative pathways, may be important in the pathogenesis of these diseases. In pemphigus, early complement components ( C1, C4, and C2) appear to be activated in addition to later components (C3 and C5), suggestive of classical pathway activation. Participation of properdin in addition to early complement components suggests local activation of both complement pathways in bullous pemphigoid and cicatricial pemphigoid. Herpes gestationis and dermatitis herpetiformis may be bullous skin diseases entirely mediated by the alternate or properdin pathway. The specific immunopathologic findings in these diseases are discussed.[1]References
