 AB    Treatment of a myelo-monocyte cell line, J22HL-60, dormantly infected
       with human immunodeficiency virus type 1 (HIV-1) with heat-inactivated
       extracts of Acholeplasma (A) laidlawii (250 micrograms/ml) enhanced
       virus production more than 45-fold as assessed by p24 viral core antigen
       assay. When treated with a suboptimal dose of TPA or TNF-alpha,
       Acholeplasma extracts further augmented virus production in J22HL-60
       cells. H7, an inhibitor of protein kinase C(PKC), almost completely
       abrogated HIV-1-inducing ability of Acholeplasma extracts in the cells.
       A. laidlawii and several other mycoplasmas also enhanced acute infection
       of U937 cells as shown by increased virus-positive cells and
       augmentation of HIV-1 production in the culture supernatant independent
       of their pathogenicity to humans.
