| Outline of Final Research Achievements |
GABAergic synaptic transmission regulates brain function by establishing the appropriate excitation-inhibition (E/I) balance in neural circuits. The structure and function of GABAergic synapses are sensitive to destabilization by impinging neurotransmitters. This GABAAR destabilization pathway is counteracted by the maintenance system which required Ca2+ release from ER via IP3 receptor. In this project, I found that the slow metabotropic glutamate receptor signaling activated IP3 receptor-dependent calcium release and promote GABAAR clustering and GABAergic transmission.
