Purified capsular polysaccharide of Cryptococcus neoformans induces interleukin-10 secretion by human monocytes

A Vecchiarelli et al. Infect Immun. 1996 Jul.

Abstract

In this study, we demonstrated that purified capsular polysaccharide of Cryptococcus neoformans is a potent inducer of interleukin-10 (IL-10) secretion by human monocytes. Endogenous IL-10 was involved in regulating tumor necrosis factor alpha and IL-1beta secretion by human monocytes in response to encapsulated C. neoformans strains. Our results suggest a new immunosuppressive effect exerted by glucuronoxylomannan through the induction of IL-10, a potent downregulator of proinflammatory cytokines.
