Upregulated expression of NKG2D and NCRs on CD56^brightCD16^+/- NK cells in HIV-HCV co-infection. a Representative examples of flow cytometric analysis of C-type lectin receptor NKG2D and NCRs NKp46 and NKp30 expression on CD56^brightCD16^+/- NK cells. b Surface expression of NKG2D on CD56^brightCD16^+/- NK cell subset in healthy controls (n = 15), HIV mono-infected (n =12), HIV-HCV co-infected (n = 12) and HCV mono-infected patients (n = 15). c Surface expression of NKp46 on CD56^brightCD16^+/- NK cell subset in healthy controls (n = 13), HIV mono-infected (n =11), HIV-HCV co-infected (n = 13) and HCV mono-infected patients (n = 15). d Surface expression of NKp30 on CD56^brightCD16^+/- NK cell subset in healthy controls (n = 16), HIV mono-infected (n =11), HIV-HCV co-infected (n = 12) and HCV mono-infected patients (n = 12). *, P < 0.05; **, P < 0.01; ***, P < 0.001; ns - not significant (P > 0.05).
