CX3CR1 expression and HIV viremia.
Expression of CX3CR1 by lymphocytes from HIV-infected patients was analyzed by flow cytometry. Typical results from a patient with a low (< 20 copies/mL) (A) or a high (36 253 copies/mL) (B) HIV viremia are shown. The fraction of CD45RO+ Th lymphocytes (C) and CD45RO− Th lymphocytes (D) expressing CX3CR1 in patients with HIV viremia below (n = 7) or above (n = 7) 10 000 copies per milliliter is shown. VL indicates viral load (HIV copies/mL); Mann-Whitney U test.
