IL-17 controls central nervous system autoimmunity through the intestinal microbiome
2021
Interleukin-17A- (IL-17A) and IL-17F-producing CD4(+) T helper cells (T(H)17 cells) are implicated in the development of chronic inflammatory diseases, such as multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). T-H 17 cells also orchestrate leukocyte invasion of the central nervous system (CNS) and subsequent tissue damage. However, the role of IL-17A and IL-17F as effector cytokines is still confused with the encephalitogenic function of the cells that produce these cytokines, namely, T-H 17 cells, fueling a long-standing debate in the neuroimmunology field. Here, we demonstrated that mice deficient for IL-17A/F lose their susceptibility to EAE, which…

In particular, these cells were shown to play a critical role in the development of experimental autoimmune encephalomyelitis (EAE), an animal model for multiple sclerosis. One of the major cytokines Th17 cells produce is IL-17A, a cytokine of the IL-17 family. IL-17A, as well as it homologue IL-17F bind and trigger cells via the IL-17 receptor A/C complex. We have used a series of mice with deficiencies in the…
IL ‐1 signaling is critical for expansion but not generation of autoreactive GM ‐ CSF + Th17 cells
2016
Abstract Interleukin‐1 (IL‐1) is implicated in numerous pathologies, including multiple sclerosis and its animal model experimental autoimmune encephalomyelitis (EAE). However, the exact mechanism by which IL‐1 is involved in the generation of pathogenic T cells and in disease development remains largely unknown. We found that following EAE induction, pertussis toxin administration leads to IL‐1 receptor type 1 (IL‐1R1)‐dependent IL‐1β expression by myeloid cells in the draining lymph nodes. This myeloid‐derived IL‐1β did not vitally contribute to the generation and plasticity of Th17 cells, but rather promoted the expansion of a GM‐CSF + Th17 cell subset, thereby enhancing its encephalitog…
