Investigate role of miRNA146a and IL-17 level in progressive rheumatoid arthritis disease.

Rheumatoid Arthritis (RA) is a chronic, progressive autoimmune disease, involves an intimate relationship between immune cells and cytokines and results in decreased lifespans and higher mortality rates. The goal of the current study was to investigate the impact of MicroRNA (miRNA)146a and interleukin-17 (IL-17) as prognosis markers in RA patients. This case-control study included 120 RA patients who visited the Rheumatology unit at Al-Saddar Medical City in the governorate of Najaf, and 30 normal controls.

Profiles of miRNA expression and IFN-γ serum level as biomarker for the development of Multiple Sclerosis.

Multiple sclerosis (MS) is associated with a wide spectrum of sensory, motor, and psychological disorders. Cytokines level and microRNA (miRNA) expression have roles in the disease's progression and the start of a damaging immune response in the central nerve system. This research study aimed to determine the role of interferon-γ (IFN-γ) and microRNA-326 (MiR-326) as prognostic factors for the development of MS disease in relation to different treatments.
