Other options may be useful for long-term therapy. The immunomodulatory antibiotic minocycline could be an effective, low-cost adjunctive treat-ment to HAART. Minocycline mediated a dose-dependent decrease in single-cycle CXCR4-tropic HIV infection and decreased viral RNA after infection of CD4+ T cells with HIV NL4-3. Reactivation from latency was also decreased in a primary CD4+ T cell-derived model and in resting CD4+ T cells from HIV-infected patients. Minocycline treatment resulted in significant changes in activation marker expression and inhibited prolif-eration and cytokine secretion of CD4+ T cells in response to activation. This study demonstrates that min-ocycline reduces HIV replication and reactivation and decreases CD4+ T cell activation. The anti-HIV effects of minocycline are mediated by altering the cellular environment rather than directly targeting virus, placing minocycline in the class of anticellular anti-HIV drugs. ? 2010 by the Infectious Diseases Society of America.
