Synoviocytes
Cells on the luminal surface of the SYNOVIAL MEMBRANE. Type A synoviocytes are MACROPHAGES responsible for waste removal from the joint cavity. Fibroblast-like type B synoviocytes are involved in production of joint matrix constituents (e.g., HYALURONAN; COLLAGEN; and FIBRONECTIN).

Arthritis, Rheumatoid
A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.

Synovial Membrane
The inner membrane of a joint capsule surrounding a freely movable joint. It is loosely attached to the external fibrous capsule and secretes SYNOVIAL FLUID.
A family of intracellular tyrosine kinases that participate in the signaling cascade of cytokines by associating with specific CYTOKINE RECEPTORS. They act upon STAT TRANSCRIPTION FACTORS in signaling pathway referred to as the JAK/STAT pathway. The name Janus kinase refers to the fact the proteins have two phosphate-transferring domains.
