Neurologic impairments associated with human immunodeficiency virus (HIV) infection in pediatric patients may affect quality of life, and can develop despite antiretroviral therapy (ART). Behavioral changes observed in clinical studies of HIV-infected children suggest alterations in dopaminergic neurotransmission. Findings from our model of choice, the HIV-1 transgenic rat, reveal a significant increase in phosphorylated tyrosine hydroxylase protein expression and a decrease in dopamine transporter mRNA, without changes in tyrosine hydroxylase (TH) or dopamine transporter (DAT) protein or in more general markers of protein and gene expression levels in the HIV-1 transgenic rat midbrain. Thus these findings suggest selective vulnerability of the dopamine system in developing brains to HIV-1 infection.
