Abstract:
:Human bronchoalveolar lavage (BAL) macrophages were obtained from normal human volunteers and infected with an AIDS-associated strain of Mycobacterium avium. Infected cells were exposed to purified envelope glycoprotein (gp120) from HIV-1 or to the recombinant non-glycosylated gp120 fragments PBI-RF and PBI-IIIB. Native gp120 increased Myco. avium growth in human cells from six separate donors, whereas the non-glycosylated fragments of gp120 had no such effect. Moreover, gp120 induced a substantial secretion of prostaglandin E2 (PGE2) from macrophages; inclusion of indomethacin blocked the enhanced permissiveness of infected cells treated with gp120. Soluble CD4 also neutralized the effect of gp120. Overall, these results indicate a role for gp120 in the susceptibility of AIDS patients to Myco. avium infections, mediated by an enhanced PGE2 release.
