Genetic Deletion of GABA_A Receptors Reveals Distinct Requirements of Neurotransmitter Receptors for GABAergic and Glutamatergic Synapse Development.

ABSTRACT: In the adult brain GABA_A receptors (GABA_ARs) mediate the majority of synaptic inhibition that provides inhibitory balance to excitatory drive and controls neuronal output. In the immature brain GABA_AR signaling is critical for neuronal development. However, the cell-autonomous role of GABA_ARs in synapse development remains largely unknown. We have employed the CRISPR-CAS9 technology to genetically eliminate GABA_ARs in individual hippocampal neurons and examined GABAergic and glutamatergic synapses. We found that development of GABAergic synapses, but not glutamatergic synapses, critically depends on GABA_ARs. By combining different genetic approaches, we have also removed GABA_ARs and two ionotropic glutamate recept
