GABA secreted by B-cells blunts the body’s cytotoxic T-cell-based response to tumors

A group of scientists led by researchers from the RIKEN Center for Integrative Medical Sciences have discovered that B-cells, a type of immune cell, secrete the neurotransmitter GABA, and also found that the GABA secreted by the B-cells promoted the emergence of anti-inflammatory macrophages, blunting the body’s cytotoxic T-cell-based response to tumors.
