Fig. 2From: Significantly enhanced lung metastasis and reduced organ NK cell functions in diet-induced obese ratsNumbers of NK cells presented as % of peripheral blood mononuclear cells (PBMCs). NK cell numbers are represented by the population with CD161abright and CD3− expression for (a) short-term experiment and (b) long term experiment and were determined by cytometry analysis after staining with the appropriate antibodies. Values represent means ± SEM, n = 8 rats/group. § indicates significant differences of means between rats receiving control diet compared to DIO fed animals (p ≤ 0.05) analyzed by two-way ANOVABack to article page
