Abnormal expression of a 170-kilodalton P-glycoprotein encoded by MDR1 gene, a metabolically active efflux pump, in CD4+ and CD8+ T cells from patients with human immunodeficiency virus type 1 infection.

Abstract

Peripheral blood CD4+ and CD8+ T cells from 16 patients with HIV-1 infection, 8 each with CD4+ T cell counts of > 200/mm3 (group I) and with CD4+ T cell counts of < 200/mm3 (group II), and 8 age- and sex-matched controls, were examined for the expression of P-glycoprotein (P-gp), a 170-kDa phosphoglycoprotein encoded by the MDR1 gene, using dual-color flow… (More)
