MDR1 gene variation predicts immune recovery after HIV treatment
A study in this week's issue of THE LANCET suggests that the ability of the immune response to recover after antiretroviral treatment for HIV-1 infection may be dependent on the composition of the MDR1gene, which encodes the P-glycoprotein.
