Is microglia pns or cns
WitrynaMicroglia and macrophages play critical roles in the response of the central and peripheral nervous systems (CNS and PNS, respectively) to injury and disease, one of which is the removal of degenerated myelin by phagocytosis.

Witryna22 lut 2024 · Although both macrophages and microglia respond, microglia are the debris-clearing cell. Once outside the CNS, microglia re-enter the spinal cord in an altered state. These peripheral nervous system (PNS)-experienced microglia can travel to distal CNS areas from the injury site, including the brain, with debris. WitrynaIn contrast to the parenchymal microglia, the perivascular microglia are definitely bone marrow derived and regularly replaced in the adult CNS as demonstrated by use of chimeric rats by Hickey and Kimura. The view that parenchymal microglia are bone marrow derived has been challenged.
