Critical role of IL-15–IL-15R for antigen-presenting cell functions in the innate immune response

Activation of dendritic cells (DCs) and macrophages by infectious agents leads to secretion of interleukin 12 (IL-12), which subsequently induces interferon-γ (IFN-γ) production by multiple cell types that include DCs and macrophages. In turn, IFN-γ acts on macrophages to augment IL-12 secretion and to produce nitric oxide (NO), which eradicates infected… CONTINUE READING
