Online now: Interleukin-34-dependent perivascular macrophages promote vascular function in the brain
The niche signals critical for the homeostasis and functions of the brain border-associated macrophages (BAMs) are not well understood. Van Hove et al. demonstrate that BAMs require IL-34 derived from mural cells and perivascular fibroblasts for their maintenance in adulthood. They show that BAMs are required to promote normal vascular function in the brain.
