Figure S1. natural killer (NK) cell receptor expressions were determined in each NK subset from FPDs. (A,B) NK activating receptors NKG2C and NKP46 were elevated in the CD16posCD56dim NK subset during human immunodeficiency virus (HIV) infection. (C,D) Inhibitory receptors NKG2A and CD158a were also elevated in the CD16posCD56dim NK subset of HIV-positive individuals. No significant difference was found among different subgroups in the CD56bright subset except CD158a expression. In CD16posCD56neg subset, however, we observed lower expression of NKP46 in HIV-positive groups compared to healthy controls. In contrast, the expression of NKG2A was higher in HIV-positive groups compared to healthy controls, and the level of CD158a in CD4low group was also higher than healthy controls.
