Schematic representation of how microglia affect neurite generation of human NPCs and differentiating neurons. Microglia stimulated either with proinflammatory agents, such as IFNγ and LPS, or with anti-inflammatory cytokines, such as IL-4 and Il-13, promote neurite outgrowth in human neural progenitor cells. Proinflammatory activated microglia augment dendritic development, but inhibits axon generation in differentiating hippocampal DG granule cells. Microglia stimulated with anti-inflammatory cytokines supposedly support axon generation in granule cells.
