- 요약During neuroinflammation, immune cells infiltrating into the CNS express and release a wide range of factors to either drive inflammation or keep it under control. This balance is regulated in part by a pro-inflammatory microRNA-155. miR-155 is expressed highly in the serum and CNS lesions of patients with multiple sclerosis. Mice lacking miR-155 have reduced disease severity during the progression of experimental autoimmune encephalomyelitis (EAE), due in part to a reduction in CNS-infiltrating Th17 T cells. I was able to utilize single-cell RNA sequencing to clearly demonstrate a reduction in CNS-infiltrating T cells, dendritic cells, and macrophages in mice lacking miR-155 expression in all cell types. I further determined, using conditional knockout mice, that although miR-155 is expressed highly throughout the immune system, not all cell types require miR-155 expression to drive EAE disease severity. Deletion of miR-155 in T cells lead to a drastic reduction in EAE disease, similar to the whole-body deletion, whereas deletion in dendritic cells lead to a less disease progression but to a lesser extent. Macrophages, while expressing high levels of miR-155, did not need miR-155 expression for full EAE disease severity. I further look into the possible interactions that DCs might have with resident glial cells during neuroinflammation to better understand how these cells could be contributing to disease. I also look into novel roles that miR-155 binding may have on non-canonical binding sites within the CDS, alternative splicing of the IL7R, and the roles of miR-155-containing extracellular vesicles during EAE.
