These receptors are involved in thepathogenesis of various neurological disorders and chronic neurodegenerative diseases[33, 34].The effect of the AF of HLDF-6 peptide on the parametersof binding between radiolabeled ligands and NMDA receptors on hippocampalmembranes and between GABA-A and 5HT2A serotonin receptors on the membranes ofthe prefrontal cortex in BALB/c mice was investigated. The gene discussed is HTR2A; the disease is nervous system disorder.
