IQSEC3, a guanine nucleotide exchange factor for ADP-ribosylation factors (ARF-GEFs) is specifically expressed at GABAergic synapses, and its loss increases seizure susceptibility in mice. However, the contribution of microglia to initiation and/or progression of seizures in IQSEC3-deficient mice has not been investigated. In the current study, we show that mice with hippocampal dentate gyrus (DG)-specific IQSEC3 knockdown (KD) exhibit microglial activation and death of DG granule cell. Furthermore, treatment of IQSEC3-KD mice with minocycline, an inhibitor of microglial activation, blocks DG granule neuron cell death and the occurrence of spontaneous seizures without affecting GABAergic synapse deficits or loss of somatostatin. Our results suggest that microglial activation is involved in a subset of IQSEC3-KD-induced epileptogenesis stages, and that its regulation could be an alternative strategy for managing epilepsy.
