In the present study, we performed the comprehensive analysis of GABAergic system in the hippocampus of Krushinsky\u2013Molodkina (KM) audiogenic rats, exposed to prolonged audiogenic kindling to reproduce the condition of temporal lobe epilepsy (TLE). According to the kindling protocol, KM rats were exposed to 21 daily seizure stimulations, whereas unstimulated (naive) KM rats were used as a control. Obtained results showed that 21\u2010day kindling was associated with a pronounced decrease in the expression of glutamate decarboxylase 67 (GAD67) and co\u2010localization of GAD67 with active cAMP\u2010response element\u2010binding protein (CREB), indicating reduced activity of GABAergic interneurons and GABA production. In addition, we observed decreased expression of synaptic vesicle glycoprotein 2A (SV2A) and lower co\u2010localization of vesicular GABA transporter (VGAT) with active phosphorylated synapsin I, suggesting an impaired presynaptic GABAergic vesicle function. Moreover, dysregulation of GABA\u2010A receptor and cation\u2010chloride transporter expression was detected, which could also exacerbate the dysfunction of GABAergic system in the hippocampus. Thus, the results suggest that prolonged audiogenic kindling in KM rats, resulting in the stabilization of severe limbic seizures and increased mortality, is associated with a pronounced and multifaceted dysregulation of GABAergic transmission in the hippocampus.<\/jats:p>","DOI":"10.1111\/ejn.70658","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T04:36:56Z","timestamp":1787546216000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Long\u2010Term
