MiRNA profiles in unstimulated and TLR stimulated MDMs

ABSTRACT: Macrophages play a crucial role in HIV-1 pathogenesis. Toll-like receptors (TLRs) are fundamental for innate and adaptive immune responses, but their role in HIV-1 infection is still incompletely understood. The TLR3 and TLR4 ligands poly(I:C) and LPS are known to modulate HIV-1 infection of and replication in monocyte-derived macrophages (MDMs), but the mechanism is incompletely understood. We found that MDMs stimulation with poly(I:C) or LPS abrogated infection by CCR5-using, macrophage-tropic HIV-1, or by VSV-G-pseudotyped HIV-1 virions, while TLR7 and TLR9 agonists Imiquimod and CpG only reduced infection to varying extent. Suppression of infection, or lack thereof, did not correlate with differential effects on CD4 or CCR5 expression, type I interferon induction, or production of pro-
