Figure 6. The effect of exercise on intracellular interleukin (IL)-6 expression in CD14⁺ monocytes.

Peripheral blood samples were obtained from 10 healthy volunteers before, immediately after, and following 2 h of resting recovery from 90 min of exercise at 55%W_max in the heat (34°C). Samples were incubated with LPS (TLR4 ligand), zymosan (TLR2 and 6 ligand), or with culture media only for 6 h, following which monocyte intracellular IL-6 expression was examined by flow cytometry. All data represent means ± s.e.m.†Statistically significant (P < 0.01) difference from pre-exercise.
