Beyond the α7 nAChR subunit, mRNA expression of α2 nAChR, α5 nAChR, α6 nAChR, α9 nAChR and α10 nAChR was detected in immune cells including mononuclear leukocytes, dendritic cells (DCs), MΦ and T-cells supporting our hypothesis that not only α7 nAChRs are involved in the regulation of immune response after stroke [12,13,14]. The gene discussed is CHRNA7; the disease is Stroke.
