“…Extensive work using immunohistochemistry and in situ hybridization in chick, mouse, rat, and rabbit have identified several subunits of nAChRs in the retina. There is expression of several subunits that comprise heteromeric nAChRs in the IPL, including the ␣3-6 (and ␣8 in chick) and 2-4 subunits (Swanson et al, 1987;Hoover and Goldman, 1992;Keyser et al, 1993;Hamassaki-Britto et al, 1994;Cimino et al, 1995;Zoli et al, 1995;Vailati et al, 1999;Champtiaux et al, 2002). Both mRNA and protein have been localized to several cell types in the inner retina, including RGCs, amacrine cells, displaced amacrine cells, and bipolar cells.…”
