Figure 1From: Altered NK cell function in obese healthy humansLeukocyte subsets in healthy normal weight and obese subject. Isolated PBMCs from healthy normal weight and obese subjects were stained with antibodies and analyzed by flow cytometry. (A) NK (CD56+CD3−) cells as percentage of lymphocytes; (B) CD56bright cells and (C) CD56dim cells as percentage of NK cells. (D) Representative flow cytometry dot plots of CD56bright and CD56dim cells from a normal weight individual; insert in the dot plot show the prior gaiting for NK cells (CD56+CD3−) in the upper left quadrant. (E) CD3+CD56+ cells as percentage of lymphocytes; (F) T (CD3+CD56−) cells as percentage of lymphocytes. Data are expressed as mean + SEM. Significant effects of obese vs. normal weight subjects are indicated by an asterisk *p < 0.05.Back to article page
