Nicotine, the selective cholinergic agonist, acts on the α7nAChR and inhibits cytokines release. Left cervical vagotomy reduces nerve terminal to release neurotransmitter acetylcholine, inhibits the interaction of acetylcholine and α7nAchR, and result in the release of cytokines out of control.
How does smoking affect vagus nerve?
Conclusions: In habitual smokers, smoking acutely reduces baseline levels of vagal-cardiac nerve activity and completely resets vagally mediated arterial baroreceptor-cardiac reflex responses.
