AB OBJECTIVE: Using CD14-positive HIV-1 infected cell line, J22HL60, we try
to find out the mechanism of HIV expression induced by LPS in
macrophage. METHODS: Induction of J22HL60 cells was proceeded for HIV
expression with or without inhibitors. HIV expression was detected by
indirect immunofluorescent staining and P24 assay. Concentration of
diacylglycerol (DAG) was measured with production of radiorabeled
compound by DAG kinase. RESULTS: Not only LPS but olso DAG was a potent
HIV inducer. Staurosporine as well as anti-CD14 antibody supressed HIV
induction. LPS stimulation increased DAG concentration in cell membrane.
DISCUSSION AND CONCLUSIONS: Protein kinase C and phospholipase C (PLC)
are involved in HIV expression in macrophage. CD-14 could transduce a
signal toward PLC.
