IL10 and relapsing-remitting multiple sclerosis: Sedeeq et al. studied IL-10 in relapsing-remitting (RR) MS in 32 RRMS (relapsing-remitting multiple sclerosis) and 26 healthy control subjects and demonstrated that IL-10 in remission was positively correlated with disease duration (r = 0.41; p = 0.02) [26].
