HIV infection of MDM superinduces MCP-1 secretion. Human MDM were infected with HIV-1 Bal (MOI: 0.1). Culture supernatants were tested for MCP-1 and RT activity contents. (A) One experiment representative of seven independently performed is shown. (B) MCP-1 levels measured at the peak of RT activity in seven independent experiments with cells obtained from eight donors; the mean ± standard deviation (SD) is shown. ** P < .01 versus uninfected by paired Student’s t test. (□) Uninfected; (▪) infected.
