Cocaine 35-42 ciliary neurotrophic factor Rattus norvegicus 103-107 8987828-4 1996 There is an increase in immunoreactivity of Janus kinase (JAK2), a CNTF-regulated protein tyrosine kinase, in the VTA after chronic but not acute cocaine administration. Cocaine 146-153 Janus kinase 2 Rattus norvegicus 58-62 8987828-8 1996 Double-labeling immunohistochemical studies show that JAK2 immunoreactivity in the VTA is enriched in dopaminergic and nondopaminergic cells, both of which exhibit increased JAK2 immunoreactivity after chronic cocaine treatment.
