TLR3 and HIV infectious disease: In order to assess the ability to poly (I:C) to modulate TLR expression in the context of HIV infection, and potentially influence cellular responses to inflammation, we measured the effect of poly (I:C) treatment on the expression of TLR3, 4, 5, and 7 on uninfected C20 cells, and compared it to that on infected cells (HC69.1 and HC01) as well as monocytic and T cells (Jurkat) without and with HIV.
