Abstract:
To investigate the cellular origin and the mechanisms of multinucleated giant cell (MGC) formation in the CNS, various cytokines were applied to isolated murine microglia. All the single cytokines failed to induce MGC. However, interleukin (IL)-13 and IL-4 induced microglial MGC formation in the presence of colony stimulating factors, which was inhibited by either anti-IL-13 or anti-fms antibody. T helper 2 (Th2)-derived cytokines can induce MGC formation even in the absence of infectious agents.
