Also, high levels of expression of miRNA-21, miRNA-155, and miRNA-182 have been detected in the cerebrospinal fluid of MS patients compared to controls, showing an important correlation with the levels of inflammatory cytokines such as IL-1β, IL-6, TNF-α, and hs-CRP levels in CSF, suggesting their involvement in the inflammatory processes of MS [87]. The gene discussed is IL6; the disease is myeloid sarcoma.
