Meningeal γδ T cell–derived IL-17 controls synaptic plasticity and short-term memory
There is now a growing appreciation of cross-talk between the nervous and immune systems. Here, Ribeiro et al. report that interleukin-17 (IL-17)–producing γδ T cells that arise early in life and home to the meninges of neonatal mice play an essential role in the development of short-term memories. Both mice lacking γδ T cells and IL-17 show […]
