Effect of NGF starvation upon HIV production in macrophages. A dramatic
difference of virus production was detected between HIV-infected M/M
exposed to anti-NGF Ab (■), HIV-infected M/M
(●), or HIV-infected M/M exposed to an
IgG-isotypic irrelevant Ab (▴). HIV p24 gag antigen
production was evaluated by commercially available ELISA at days 2, 5,
8, 11, and 14 after virus infection. The figure represents a typical
experiment of three.
