Figure 4.
The frequency of visceral adipose tissue (VAT)-associated NKT cells, but not NK cells, is increased in colorectal cancer (CRC)-affected subjects as compared to cancer-free donors. VAT stromal vascular fraction (SVF) and peripheral blood (PB) lymphocytes isolated from lean normal weight (Nw), obese (Ob), lean affected by CRC (Nw/CC), and Ob affected by CRC (Ob/CC) donors were analyzed by flow cytometry. Frequencies of NKT (CD3+CD56+) (A) and NK (CD3−CD56+) (B) cells were evaluated in the four categories of donors. Each dot represents an individual donor. Mean ± SEM is shown for each group. *p < 0.05, by analysis of variance.
