Predominant T lymphocytic inflammation in FGF21 KO obese mice.

<p>(A) Representative cytofluorometric dot plots of isolated lymphocytes from WT and FGF21 KO animals consuming high fat diet for 16 weeks. FGF21 KO mice show elevated CD45+ (i), TCRb+ and Thy1+ T lymphocytes (ii) and Foxp3+ Treg cells. CD19+ B lymphocytes were not significantly altered (iii). Corresponding summary data is shown in the right panel. The experiment was repeated twice (n = 4 per group). (B) Gene expression analysis of cytokines is presented. n = 7 per group.
