Advances in study of abnormal metabolism of fibroblast-like synoviocytes in rheumatoid arthritis / 中国药理学通报

ABSTRACT

Metabolomics studies have shown metabolic disorders in patients with rheumatoid arthritis (R A) . However, the metabolic characteristics of individual cell types associated with RA have sparsely been elucidated. Fibroblast-like synoviocytes (FLS) are the main cell types at the synovial tissue of joint, which can lead to joint destruction through invading articular cartilage. In the microenvironment of inflammatory tissues, the metabolism of glucose, lipids, amino acids, glutamine and other key nutrients in RA-FLS changes, which are involved in the abnormal activation of FLS and disease activities. The research progress on key molecules of RA-FLS energy metabolism abnormalityin recent years were summarized in this paper, providing a basis for elucidating the pathological mechanism of RA and discovering new drug targets.
