Ketogenic diet enhances human T cell immune capacity in vivo.Figure 5Healthy volunteers conducted a three week KD with a limited carbohydrate consumption of <30g per day. Blood was taken and analyzed prior to (T0) and post KD (T1). PBMCs were isolated. T cell stimulation was performed through CD3/CD28 Dynabeads at a bead:cell ratio of 1:8. CD4+/CD8+ T cells were separated via magnetic cell labeling. A IL2, IL4, and CTLA4 mRNA expression in stimulated CD4+ T cells, n=17/18/17 individual human subjects. Data information: Data depicted as box plots with median, twenty-fifth and seventy-fifth percentiles and range. Dots indicating individual values. *p<0.05, paired t-test/ Wilcoxon matched-pairs signed rank test, as appropriate.
