Abstract Microglia are innate immune cells of myeloid origin that take up residence in the central nervous system CNS during embryogenesis. While classically regarded as macrophage-like cells it is becoming increasingly clear that reactive microglia play more diverse roles in the CNS. Microglial activation is often used to refer to a single phenotype however in this review we consider that a continuum of microglial activation exists with phagocytic response innate activation at one end and antigen presenting cell function adaptive activation at the other. Where activated microglia fall in this spectrum seems to be highly dependent on the type of stimulation provided. We begin by addressing the classical roles of peripheral innate immune cells including macrophages and dendritic cells which seem to define the edges of this continuum. We then .
