Convergent evolution of scavenger cell development at brain borders

The vertebrate central nervous system is protected by the blood-brain barrier and meningeal membranes, which ensure immune privilege¹. In the mammalian brain, microglia and barrier-associated or border-associated macrophages (BAMs) provide immune surveillance and scavenge wastes², yet how evolution
