Abstract
This study investigates the frequency and numbers of circulating helper innate lymphoid cells (ILCs) in untreated relapsing-remitting multiple sclerosis (RRMS) patients, focusing on intracellular IL-10 and CCR6 expressions under IL-2, IL-33, and retinoic acid (RA) stimulation in vitro and their associations with clinical features in RRMS. In RRMS patients, ILC1 levels were notably higher upon IL-2 + IL-33 + RA stimulation, while ILC2 levels, particularly the c-Kit+ ILC2 and CCR6+ ILC2 subsets, were significantly lower compared to unstimulated conditions. Additionally, IL-10+ ILC1 levels were elevated. The ratios of IL-10+ ILC1/ILC1, c-Kit+ ILC2/c-Kit– ILC2, and CCR6+ ILC2/ILC2 were associated with the progression index (PI) in RRMS patients.
