Figure 7From: Dynamic analysis of Th1/Th2 cytokine concentration during antiretroviral therapy of HIV-1/HCV co-infected Patients Changes of Th1 and Th2 cytokine expression levels during HAART in both HIV mono-infection and HIV/HCV co-infection group. Vertical axis represents cytokine concentration (pg/ml) in plasma. The orange line represents Th1 cytokine cumulative concentration (pg/ml); the blue line represents Th2 cytokine cumulative concentration (pg/ml).Back to article page
