Increased chemokine receptor CXCR3 expression on CD56^brightCD16^+/− NK cells in HIV-HCV co-infection. a Representative dot plots obtained from the measurement of CXCR3 expression on CD56^brightCD16^+/− NK cells by flow cytometry. b CXCR3 expression on CD56^brightCD16^+/− NK cells in healthy controls (n = 10), HIV mono-infected (n =12), HIV-HCV co-infected (n = 21) and HCV mono-infected patients (n = 12). **, P < 0.01; ***, P < 0.001; ns - not significant (P > 0.05). In the dot plot figure horizontal line represents Log % Mean ± SEM
