WebMay 20, 2024 · GABAergic inhibition of T cell proliferation by benzodiazepines could be rescued by GABA (A)R blocking. Our data suggest that benzodiazepines influence T cell proliferation through both TSPO and GABA (A)Rs activation. Conclusions: We conclude that activation of GABA (A)Rs provides immunosuppression by inhibiting T cell proliferation. WebGABA is the main inhibitory neurotransmitter in your brain, stopping the chemical messages from passing from nerve cell to nerve cell. Glutamate, on the other hand, is the main excitatory neurotransmitter in your brain, permitting the chemical messages to be carried from nerve cell to nerve cell.
