Parasite-derived anti-inflammatory immunomodulatory protein

摘要

A protein with anti-inflammatory, and immunomodulatory functions was identified and isolated from the excretory/secretions of a human parasite Schistosoma mansoni. This protein, designated herein as Sm 16.8, is released by schistosomes upon entry into human skin. Under in vitro conditions Sm 16.8 is shown to stimulate the production of anti-inflammatory cytokine Interleukin-1 receptor antagonist (IL-1ra) in human keratinocytes and transciptionally down regulate the production of proinflammatory cytokines IL-1 alpha and IL-1 beta.
