Adaptogens are stress-response modifiers which have been considered to exert important influences on cytokines activities and immune response. Here, we investigated the effects of Rhodiola rosea (R. rosea), a natural adaptogen on the experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS). We found that R. rosea alleviated the severity of EAE as evaluated by clinical and histopathology scores. R. rosea decreased IL-6, sIL-6R, IFN-γ and IL-17A in both serum and splenocytes supernatants while increased IL-4 in splenocytes supernatants of EAE mice. R. rosea also modulated the T cell response by inhibiting Th1 and Th17 cells, restoring Treg cells, combining with regulated Th17/Th1, Th17/Th2 and Th17/Treg ratios in the spleen, inguinal lymph nodes, brain and spinal cord of EAE mice. Furthermore, R. rosea regulated the expression of JAK1, JAK2, STAT3 and RORγt in the spinal cord of EAE mice. Together, our findings suggested the adaptogenic effects of R. rosea on EAE, which may help to deepen the understanding of potential therapeutic values of traditional Chinese medicines for autoimmune diseases of CNS.

D004681 Encephalomyelitis, Autoimmune, Experimental An experimental animal model for central nervous system demyelinating disease. Inoculation with a white matter emulsion combined with FREUND'S ADJUVANT, myelin basic protein, or purified central myelin triggers a T cell-mediated immune response directed towards central myelin. The pathologic features are similar to MULTIPLE SCLEROSIS, including perivascular and periventricular foci of inflammation and demyelination. Subpial demyelination underlying meningeal infiltrations also occurs, which is also a feature of ENCEPHALOMYELITIS, ACUTE DISSEMINATED. Passive immunization with T-cells from an afflicted animal to a normal animal also induces this condition.
