Concentration-dependent effects of CSF1R inhibitors on oligodendrocyte progenitor cells ex vivo and in vivo.

ABSTRACT: Microglia are the principal resident immune cells in the central nervous system (CNS) and play important roles in CNS development, maintenance and repair. The survival and development of microglia depends on colony-stimulating factor 1 receptor (CSF1R), a member of the platelet-derived growth factor receptor (PDGFR) family of tyrosine kinases. Recently pharmacological CSF1R inhibition has been used to investigate the effects of microglial depletion in numerous animal models of CNS disease. However, the effects of CSF1R inhibitors on other cell types in the CNS remains incompletely characterized. In this report, we compared the effect of two commonly used CSF1R inhibitors, PLX5622 and PLX3397, on microglia and oligodendrocyte progenitor cell (OPC) numbers. In ex vivo cerebellar slices and a
