title: Effect of a recombinant HIV gp160 vaccine on monokine production.
abstract: An investigation was undertaken to determine whether a recombinant gp160 envelope protein, which is currently being evaluated as a vaccine for AIDS, induces or modulates the production of tumour necrosis factor-alpha (TNF-alpha) or interleukin-1 beta (IL-1 beta). Incubation of monocytes from healthy, HIV-seronegative persons with 0.0001-1.0 micrograms of the recombinant vaccine did not result in the secretion of TNF-alpha or IL-1 beta, nor did the recombinant product augment or suppress monokine production by lipopolysaccharide (LPS) stimulated monocytes. The vaccine was also without a stimulatory or modulatory effect upon TNF-alpha or IL-1 beta secretion by monocytes from a patient with the AIDS-related complex (ARC) and from the monocytic THP-1 cell line. The lack of effect of gp160 on monokine production has important implications for its efficacy as a vaccine for AIDS.
