Whereas nociceptors of both A and C-fibers respond to both chemical mediators from damaged tissue and mechanical stimuli, and chemoreceptors of C-fibers respond to inflammatory mediators and inhaled chemical irritants ( Clinical studies associate bronchial asthma symptoms such as wheezing, chest tightness, and cough with dysfunction of airway sensory nerve fibers ( Afferent TRPV1 signaling: Mechanistic evidence indicates that afferent vagal nociceptors, such as transient receptor potential cation channel subfamily V member 1 (TRPV1) innervated in airways, can be activated by inflammatory mediators like histamine, bradykinin, prostaglandins, and inhaled irritants in allergen-exposed asthmatic airways ( Figure 10 , the activated TRPV1 nociceptor signaling in vagal afferent C and A-fibers innervating the airway epithelium transmits the signals to NTS in the brainstem, where the C-fiber receptors release neuropeptides such as calcitonin gene-related peptide (CGRP) and tachykinins like Substance P, and neurokinin A (NKA), promoting the parasympathetic reflex ( Figure 10 Efferent parasympathetic acetylcholine and Substance P signaling pathways: Preclinical studies demonstrate that the parasympathetic reflex arc controls airway smooth muscle contraction via a defined neural pathway ( Figure 11 ( Figure 11 ), which then release ACh to stimulate the M3 muscarinic acetylcholine receptor (mAChR) on ASMCs, causing bronchoconstriction ( Figure 11 This binding of neurotransmitter Ach to M3 mAChR, which is a G-protein coupled receptor, leads to activation of the G protein Gq, followed by sequential activation of downstream target phospholipase C (PLC), in ASMC
