Engrafted parenchymal brain macrophages differ from microglia in transcriptome, chromatin landscape and response to challenge
Abstract
Irradiation depletes brain microglia cells and induces replenishment of the pool by bone marrow (BM)-derived macrophage. Here the authors show, using mouse BM chimera, that BM-derived macrophages establish long-term residency in the brain, but remain distinct from resident microglia in their transcriptome and gene accessibility landscape.
