Melatonin exerts immunoregulatory effects by balancing peripheral effector and regulatory T helper cells in myasthenia gravis


Figure 3. In vitro melatonin administration attenuated the production of other proinflammatory cytokines. (A) IL-4, IL-6, IL-9, IL-22 and IL-21 levels in PHA-stimulated PBMC culture supernatant after melatonin administration in different MG subgroups (HC, n=10; NIST-MG, n=13; IST-MG, n=15). (B) FCM analysis of the frequency of CD4+ T cells producing IL-6 and (C) IL-9 and representative plots (HC, n=10; MG, n=10). The data are presented as the mean ± SD. * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001, **** P ≤ 0.0001.
