1 Chronic nicotine treatment led to a small decrease in alpha3/alpha6beta2* nAChR subtypes. Nicotine immunoglobulin kappa variable 2D-28 Homo sapiens
2 The decline in alpha3/alpha6beta2* subtypes, defined using alpha-conotoxinMII-sensitive (125)I-epibatidine or [(125)I]A85380 binding, was significantly smaller in striatum of nicotine-treated lesioned monkeys compared with unlesioned monkeys. Nicotine immunoglobulin kappa variable 2D-28 Homo sapiens
3 These data suggest that there are at least two striatal alpha3/alpha6beta2* subtypes that are differentially affected by chronic nicotine treatment in lesioned animals. Nicotine immunoglobulin kappa variable 2D-28 Homo sapiens
4 In addition, the results showing an improvement in striatal alpha4beta2* and select alpha3/alpha6beta2* nAChR subtypes, combined with previous work, demonstrate that chronic nicotine treatment restores and/or protects against the loss of multiple molecular markers after nigrostriatal damage. Nicotine immunoglobulin kappa variable 2D-28 Homo sapiens
