Human immunodeficiency virus (HIV-1) infects the brain and causes a progressive encephalopathy in 20 to 30% of infected children and adults called AIDS dementia complex. Evidence from in vitro and in vivo studies suggests a role for the viral envelope glycoprotein gp120, as a mediator of neurotoxicity. However, the site of interaction of gp120 with neurons and astrocytes to mediate neuronal death is still unknown. Recently the chemokine receptors, CCR5 and CXCR4, have been identified as co-receptors together with CD4 for HIV-1 entry into the target cells, suggesting a possible role for these receptors in the pathogenesis of the HIV-1 infection in the brain. Here we report the expression of CCR5 and CXCR4 in many different rat brain areas. We also found both receptors in cultured type I astrocytes demonstrating that glial cells may represent an important target for chemokines in vivo. Indeed, the functional capacity of CXCR4 receptor in astrocytes was demonstrated showing that SDF 1 alpha induced an increase of intracellular calcium concentration.
