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
It has been proposed that small quantities of microbial material within synovial joints may act as a trigger for development of synovitis. We have previously identified an association between intra-articular bacteria and development of inflammatory stifle arthritis and cranial cruciate ligament
OBJECTIVE
To examine the effect of anti-reshaping human interleukin-6 receptor monoclonal antibody (anti-rsHuIL-6R mAb) on patients with rheumatoid arthritis (RA), using SCID mice in which human RA synovial tissue has been grafted (SCID-HuRAg).
METHODS
Tissue from human RA pannus was implanted
Immune synovitis in rabbits was investigated as a potential in vivo model for evaluating new antiinflammatory agents. Antigen-induced increases in knee width as well as beta-glucuronidase and acid phosphatase activities in exudates were observed. Histologically, polymorphonuclear leukocytes appeared
The majority of dogs with ruptured cranial cruciate ligaments (crCLs) have inflammatory changes of the stifle joint suggesting that synovitis is an important factor which is involved in the development of degenerative ligament changes. Detailed information is not available concerning the possible
OBJECTIVE
To determine the cytochemical and functional phenotype of multinucleated giant cells in pigmented villo nodular synovitis (PVNS).
METHODS
Giant cells isolated from a patient with PVNS of the knee were assessed for a number of markers used to distinguish osteoclasts from macrophages/
The authors investigated ultrastructural cytochemical features of multinucleated and mononuclear stromal cells in giant cell tumor of bone (GCTB), giant cell tumor of tendon sheath (GCTTS), and pigmented villonodular synovitis (PVNS). Specimens of each tumor, respectively numbering 4, 4, and 3, were
The aim of this study was to determine the histologic and cellular characteristics of 2 cell types, mononuclear cells (Mos) and multinuclear giant cells (GCs), that predominantly constitute pigmented villonodular synovitis (PVS). Synovial tissues examined in this study were obtained from 10 patients
We describe an elderly woman who developed remitting seronegative symmetrical synovitis with pitting edema (RS3PE). In addition to typical findings, she had increased alkaline phosphatase; and investigations revealed metastatic gastric carcinoma. The literature relating to RS3PE in association with
Recent studies indicated that the nicotinamide dinucleotide phosphate oxidase (NADPH) oxidase-derived oxygen radicals plays a deleterious role in arthritis. To study this in more detail, gonarthritis was induced in NADPH oxidase-deficient mice. Mice received an intraarticular injection of either
Cranial cruciate ligament rupture (CR) is a degenerative condition in dogs that typically has a non-contact mechanism. Subsequent contralateral rupture often develops in dogs with unilateral CR. Synovitis severity is an important factor that promotes ligament degradation. Consequently, we wished to
Pigmented villonodular synovitis (PVNS) and the histologically related lesion giant cell tumor of tendon sheath (GCTTS) are idiopathic, proliferative lesions that can induce osteolysis and formation of bone cysts. These lesions contain two predominant cell types: mononuclear polyhedral cells and
This study was to investigate the role of adenosine A2A receptors (A2AR) in inhibiting the effect of electroacupuncture (EA) on osteoclastogenesis in collagen-induced arthritis (CIA).Methods
Wistar rats were divided into four groups: sham-control
The effects of intra-articular injection of small amounts of E. coli lipopolysaccharide (LPS) into the intercarpal joint of 5 ponies were studied. The LPS induced predictable changes all of which were analogous to acute bacterial infection, except that the development of signs occurred sooner after
We analyzed the influence of treadmill running on rheumatoid arthritis (RA) joints using a collagen-induced arthritis (CIA) rat model. Eight-week-old male Dark Agouti rats were randomly divided into four groups: The control group, treadmill group (30 min/day for 4 weeks from 10-weeks-old), CIA group
