It also stimulates the production of proinflammatory mediators : nitric oxide, interleukin 1 (IL-1), IL-6, IL-8, and tumor necrosis factor ?.
FliC (flagellin) can activate the innate immune system by TLR5 (toll like receptor 5) and is an important proinflammatory molecule. FliC also induces the production of antibodies and is identified as an antigen by CD4+ T cells.
General description
