Dedicated macrophages organize and maintain the enteric nervous system
Resident macrophages of the muscularis externa refine the enteric nervous system (ENS) early in life by pruning synapses and phagocytosing enteric neurons, and later switch to a neuro-supportive function, indicating that the ENS is governed by a dedicated population of resident macrophages that adapt to the timely needs of the ENS.
