OBJECTIVE
T cell protein tyrosine phosphatase (TC-PTP) is an important regulator of hematopoiesis and cytokine signaling. Recently, several genome-wide association studies have identified single-nucleotide polymorphisms (SNPs) in the locus of TC-PTP that are associated with rheumatoid arthritis and
Explants of synovial cells in rheumatoid arthritis display a transformed phenotype with focus formation and anchorage-independent growth. Many of the cytokines that activate these fibroblasts mediate their action through tyrosine kinase growth factor receptors. Mechanisms of signal transduction via
BACKGROUND
Pigmented villonodular synovitis (alternatively known as diffuse-type giant cell tumour) is a rare, locally aggressive tumour driven by a specific translocation resulting in the overexpression of colony-stimulating factor 1 (CSF1). CSF1 receptor (CSF1R) inhibitors (ie, tyrosine kinase
OBJECTIVE
To test whether the tyrosine kinase Tyro3 affects arthritis. Tyro3, the ligand of growth arrest-specific protein 6 (GAS6) is a receptor tyrosine kinase involved in cell survival. Tyro3 and GAS6 are expressed in the arthritic synovium, and in vitro studies have shown their role in
The development of small-molecule inhibitors of inflammatory cascade signaling kinases offers a potential approach to treating rheumatoid arthritis (RA). Spleen tyrosine kinase is one such tyrosine kinase. Recent research efforts have focussed on the development and testing of a spleen tyrosine
Spleen tyrosine kinase (Syk) is a cytoplasmic tyrosine kinase involved in signalling in many of the cells that drive immune inflammation. The development of small molecules that inhibit Syk kinase may change the way we treat disorders such as rheumatoid arthritis (RA), as well as a range of other
We recently demonstrated that CSF1, the ligand of the tyrosine kinase receptor, CSF1R, can be translocated in pigmented villonodular synovitis (PVNS) and tenosynovial giant cell tumor (TGCT). In this study, we evaluated the staining characteristics of PVNS/TGCT and reactive synovitides for CSF1 and
Two of the key events in the pathogenesis of rheumatoid arthritis are the synovial cell proliferation and lymphocyte infiltration into the synovium. The resulting synovitis is longlasting and leads to destructive arthritis, which is a hallmark of rheumatoid arthritis. Accumulating evidence suggests
Rheumatoid arthritis (RA) is a multifactorial autoimmune disease that primarily manifests as persistent synovitis and progressive joint destruction. Imatinib exhibited a therapeutic effect in murine collagen-induced arthritis (CIA) via selective inhibition tyrosine kinases. The second-generation
OBJECTIVE
Giant cell tumor of tendon sheath and pigmented villonodular synovitis are synovial-based diseases that are generally treated by surgery. For aggressive and recurrent tumors, treatment alternatives are needed. This review explores a targeted therapeutic strategy.
RESULTS
Imatinib, a
Rheumatoid arthritis (RA) is an autoimmune synovitis characterized by the formation of pannus and the destruction of cartilage and bone in the synovial joints. Although immune cells, which infiltrate the pannus and promote inflammation, play a prominent role in the pathogenesis of RA, other cell
Mice with a disrupted gp49B gene, which encodes gp49B1 that is expressed on certain hematopoietic cells and has two immunoreceptor tyrosine-based inhibitory motifs (ITIM), exhibit augmented FcepsilonRI-initiated mast cell degranulation and resultant tissue edema. gp49B1-deficient (gp49B(-/-)) mice
OBJECTIVE
To investigate the involvement of Tie-1 and Tie-2, receptor tyrosine kinases required for angiogenesis, in synovial proliferation and angiogenesis of rheumatoid arthritis (RA).
METHODS
Synovial tissues from 10 patients with RA and three control subjects were analysed by double
TKs are intracellular signaling molecules essential for cell homeostasis. Inhibition of TKs is used in treatment of malignancies and diabetes mellitus. The present study evaluated the role of Flt3 in antigen-induced arthritis. Mice were immunized with mBSA, and arthritis was induced by an i.a.
UNASSIGNED
Adequate surgical resection remains the treatment of choice for tenosyovial giant cell tumor (TGCT). However, diffuse type TGCT (D-TGCT) is more difficult to resect and has a higher rate of recurrence (up to 50 %), which is often multiple. D-TGCT is rarely lethal and only rare cases of
