Nicotine Suppresses Human Memory Th Cell Subsets With Preferential Effects on Central Memory Th Cells in an α7 Nicotinic Acetylcholine Receptor-Dependent Manner

Author(s): Gholizadeh F; Hajiaghayi M; Rahbari N; Choi JS; Heidt S; Como A; Kazerouni M; Kargar M; Pinard-LaRoche A; Shih SCC; Darlington PJ;

Memory T helper (Th) cells sustain protective recall responses but can also drive chronic inflammation, necessitating precise regulation of their effector programs. Although Th cells produce acetylcholine (ACh) and express nicotinic acetylcholine receptors (nAChRs), the contribution of nAChRs to ...

Background: T helper 17 (Th17) cells produce IL-17A cytokine and can exacerbate autoimmune diseases and asthma. The ß2 adrenergic receptor is a g protein-coupled receptor that induces cAMP second messenger pathways. We tested the hypothesis that terbutaline, a ß2-adrenergic receptor-specific agon ...
