Enteroglial-derived S100B protein integrates bacteria-induced Toll-like receptor signalling in human enteric glial cells

Abstract

Human EGC interact with bacteria and discriminate between pathogens and probiotics via a different TLR expression and NO production. In EGC, NO release is impaired in the presence of specific inhibitors of the TLR and S100B pathways, suggesting the presence of a novel common pathway involving both TLR stimulation and S100B protein upregulation.
