- Animal Study
- This study provides evidence that nicotine alters the infiltration of proinflammatory monocytes and neutrophils into the CNS of EAE mice via multiple nAChRs, including the α7 and α9 subtypes. Nicotine appears to achieve these effects by inhibiting the expression of CCL2 and CXCL2, two cytokines involved in the chemotaxis of proinflammatory monocytes and neutrophils, respectively. The use of ligands that are selective for one or both of these nAChR subtypes may offer a beneficial clinical outcome, and thus provide a valuable therapeutic strategy for neuroinflammatory disorders such as MS.
