Circulating Treg subsets are not affected by long-term physical exercise in MS.

The percentage of circulating Treg subsets was determined using flow cytometry. Results are shown as mean percentage ± SEM.

Treg, regulatory T cell; FoxP3, forkhead box P3; IL, interleukin; Tr1, type 1 regulatory T cell; TGF, transforming growth factor; Th3, T helper 3 cell; EX, exercise group; SED, sedentary control group; PRE, baseline measurement; POST, measurement after 12 weeks; SEM, standard error of the mean.
