What Are Cholinergic Nicotinic Agonists?
Definition:
Cholinergic nicotinic agonists are compounds that activate nicotinic acetylcholine receptors (nAChRs), a subtype of cholinergic receptors involved in cognitive functions and neuroprotection.
Receptor Subtypes and Therapeutic Targets:
- α4β2 nAChRs: Predominant in the brain, associated with cognition enhancement and nicotine addiction.
- α7 nAChRs: Implicated in neuroinflammation, neurodegeneration, and schizophrenia.
