Establishment of HIV-1-producing cells from peripheral mononuclear cells cultured with normal human serum.

Abstract

Normal human serum (NHS) contributed to the establishment of cells producing HIV-1 under the conditions of coculture of peripheral mononuclear cells (PMC) from HIV-1 seropositive patients and of PHA-prestimulated or -non-stimulated PMC from seronegative healthy donors. No addition of IL-2 and Polybrene was necessary. Since, in the case 90101, the mitochondrial displacement-loop DNA showed identical sequences in the established cells and the HIV-1 seropositive patient's cells, it can be asserted that the HIV-1-producing cells originated from the patient. These cells are still releasing HIV-1-virion more than one year after their establishment.
