Ionotropic neurotransmitter receptors
Web8 mrt. 2024 · Ionotropic neurotransmitter receptors mediate fast synaptic transmission by functioning as ligand-gated ion channels. Fast inhibitory transmission in the brain is mediated mostly by ionotropic GABA A receptors (GABA A Rs), but their essential components for synaptic localization remain unknown. WebKeywords: dopamine, glutamate, calcium, excitotoxicity, ionotropic glutamate receptors, neuroprotection DOI: 10.1134/S1990747822060058 INTRODUCTION Dopamine is a neurotransmitter involved in the regulation of various brain functions. The distur-bances of dopamine metabolism and signaling lead to the development of neurodegenerative …
