Popis: Background: The 5-hydroxytryptamine-1A receptors are known to be involved in the inhibition of seizures in epilepsy. Objective: The main aim of the present study is to determine the functional coupling to G-protein of the 5-HT1A receptor through 8-OH-DPAT-stimulated [35S]GTPγS binding assay in lateral temporal neocortex tissue of patients with mesial temporal lobe epilepsy (mTLE) and correlate it with clinical data. Material and methods: The activation of the G protein complex was determined by [35S]GTPγS binding assay. The temporal neocortex tissue was obtained from 5 patients with mTLE during epilepsy surgery and from 5 subjects (autopsies) who died due to an accident and without history of neurological disease. Results: We found that values of maximal stimulation (Emax) of [35S]GTPγS binding significant decreased in the mTLE group (30.8%, p
