| abstractText | The proprotein convertase Furin plays crucial roles in the pathology of many diseases. However, the specific role of furin in epilepsy remains unclear. In our study, furin protein was increased in the temporal neocortex of epileptic patients and in the hippocampus and cortex of epileptic mice. The furin transgenic (TG) mice showed increased susceptibility to epilepsy and heightened epileptic activity compared with wild-type (WT) mice. Conversely, lentivirus-mediated knockdown of furin restrained epileptic activity. Using whole-cell patch clamp, furin knockdown and overexpression influenced neuronal inhibitory by regulating postsynaptic gamma-aminobutyric acid A receptor (GABAAR)-mediated synaptic transmission. Importantly, furin influenced the expression of GABAAR beta2/3 membrane and total protein in epileptic mice by changing transcription level of GABAAR beta2/3, not the protein degradation. These results reveal that furin may regulate GABAAR-mediated inhibitory synaptic transmission by altering the transcription of GABAAR beta2/3 subunits in epilepsy; this finding could provide new insight into epilepsy prevention and treatment. |
