N2 - gamma-aminobutyric acid (GABA) is the main neuroinhibitory transmitter in the brain. Here we show that GABA in the extracellular space may affect the fate of pathogenic T lymphocytes entering the brain. We examined in encephalitogenic T cells if they expressed functional GABA channels that could be activated by the low (nM-1 microM), physiological concentrations of GABA present around neurons in the brain. The cells expressed the alpha1, alpha4, beta2, beta3, gamma1 and delta GABAA channel subunits and formed functional, extrasynaptic-like GABA channels that were activated by 1 microM GABA. 100 nM and higher GABA concentrations decreased T cell proliferation. The results are consistent with GABA being immunomodulatory.
