Abstract Microglia are perhaps the most underestimated cell type of our immune system. Not only were immunologists unaware of their capabilities until recently, but also, some neuroscientists denied their actual existence until the late 20th century. Nowadays, their presence is confirmed extensively, as demonstrated by numerous reports describing their involvement in virtually all neuropathologies. However, despite distinct approaches, their origin remains a point of controversy. Although many agree about their myeloid-monocytic ancestry, the precise progenitor cells and the differentiation mechanisms, which give rise to microglia in the different developmental stages of the CNS, are not unraveled yet. Mostly, this can be attributed to their versatile phenotype. Indeed, microglia show a high morphological plasticity, which is related to their functional state. This review about microglia aims to introduce the reader extensively into their ontogeny, cell biology, and involvement in different neuropathologies.
