Uncharacterized central and peripheral cough receptors

Uncharacterized central and peripheral cough receptors" is not the name of a single molecule or receptor, but a broad, descriptive term that refers to the complex neural network—including multiple classes of peripheral sensory fibers (primarily vagal sensory neurons from the jugular and nodose ganglia), ion channels (e.g., TRPV1, P2X3), and central neural pathways in the brainstem and higher centers—that regulate the cough reflex and its hypersensitivity in disease settings. This term does not refer to a specific, molecularly defined target, but rather encompasses a variety of molecular and anatomical structures involved in the initiation and modulation of cough, thus it cannot be used to designate a canonical name, abbreviation, or unique drug target. Key context: - Peripheral "cough receptors" include both chemosensitive C-fibers and mechanosensitive Aδ-fibers, most commonly studied in relation to vagal sensory pathways. - Central cough regulation involves nuclei in the brainstem (e.g., nucleus tractus solitarius) and higher cortical inhibition and excitation. - Recent research targets discrete molecular components (TRPV1, P2X3, NK-1, etc.) rather than a single "cough receptor," and no unified molecular entity termed "central and peripheral cough receptor" exists. This entry is best interpreted as a placeholder or umbrella term pending future molecular characterization.
