Central nervous system receptor

Central nervous system (CNS) receptors are a broad and heterogeneous class of proteins located within the brain and spinal cord that mediate the effects of neurotransmitters, hormones, and drugs [1]. This term does not refer to a single molecular entity but serves as a collective designation for various receptor families, including G protein-coupled receptors (GPCRs), ligand-gated ion channels (ionotropic receptors), and nuclear receptors [2]. These receptors are fundamental to the regulation of all neurological processes, such as synaptic transmission, neuronal excitability, and signal transduction pathways that govern behavior, cognition, and motor control [3]. Dysregulation or genetic mutations in specific CNS receptors are implicated in a wide array of pathologies, including Alzheimer's disease, schizophrenia, epilepsy, and major depressive disorder [4]. Because of their central role in physiology, they are the primary targets for a vast number of pharmacological interventions, including analgesics, antipsychotics, and antidepressants [5]. However, the development of drugs targeting CNS receptors is uniquely challenging due to the requirement for blood-brain barrier penetration and the need for high subtype selectivity to avoid significant side effects [6].
