Therapy naïve co-infected subjects had greater IFN-c producing CD8 + T-cells in response to HIV peptides compared to HCV mono-infected individuals [1.3960.37% vs 0.0260.0%, p,0.05], and HAART was associated with a significant reduction in the frequencies of these cells [1.3960.37% vs 0.3060.26%, p,0.05] (figure 2b). The tetramer cytokine response pattern was shown to be different in the liver compared to blood of the same individual, with diminished intra-hepatic tetramer-specific IFN-c responses and an increase in both CD107a and TNF-a responses, with the majority of SL9 tetramer positive cells expressing these two markers. Therapy naïve co-infected individuals demonstrated a higher frequency of intra-hepatic CD8 + T-cells that produce TNF-a in response to both HCV and HIV antigen stimulation compared to HCV mono-infected individuals.	./cache/cord-000008-3dgjv0x1.txt	./txt/cord-000008-3dgjv0x1.txt
