AB Sera from persons with AIDS contain inhibitors of lymphocyte
proliferation. Inhibitory activity can be detected before the
development of AIDS in humans. There appear to be at least three
distinct suppressive moieties, one of which is prostaglandin E2. We and
others had previously shown that serum samples from subjects with AIDS
contained antibody to the cell line HUT 102B2. We attempted to remove
this antibody and to determine if that action would also remove the
inhibitory activity present in human immunodeficiency virus-positive
sera. We incubated sera from subjects with AIDS with HUT 102B2 cells and
tested the resultant supernatants for inhibition of cell proliferation.
We found that this procedure significantly reversed inhibition by serum.
Other cells and cell lines were similarly tested, but only HUT 102B2
cells absorbed the inhibitory product(s). However, we determined that
secretory material from another cell line, MLA 144, also reversed
inhibition. The physical characteristics of the supernatant were
investigated. Thus, two procedures and likely separate products,
possibly cytokines, reverse immunosuppression by sera from persons with
AIDS.
