Bone destruction by Th17
Most cell junction proteins increase endothelial cell–cell adhesion. But junction adhesion molecule-C (JAM-C), despite its sticky name, loosens vascular endothelial cell connections, thus allowing increased blood vessel permeability. Increasing the permeability of small blood vessels is essential for new vessels to form and for leukocytes to escape the circulation and enter surrounding tissues ...
متن کاملTh17 cells, not IL-17+ γδ T cells, drive arthritic bone destruction in mice and humans.
The mechanism whereby IL-17 drives rheumatoid arthritis remains incompletely understood. We demonstrate that anti-IL-17 therapy in collagen-induced arthritis ameliorates bone damage by reducing the number of osteoclasts in joints. We found equal numbers of CD4(+) Th17 and IL-17 producing γδ T cells in the joints of arthritic mice, and in vitro, both populations similarly induced osteoclastogene...
متن کاملBone destruction in arthritis.
Rheumatoid arthritis (RA) is characterised by the presence of an inflammatory synovitis accompanied by destruction of joint cartilage and bone. Destruction of cartilage matrix results predominantly from the action of connective tissue proteinases released by RA synovial tissues, chondrocytes, and pannus tissue. Several lines of evidence in RA and in animal models of arthritis support a role for...
متن کاملImmune regulation of bone loss by Th17 cells
A significant macrophage and T-cell infiltrate commonly occurs in inflammatory joint conditions such as rheumatoid arthritis that have significant bone destruction. Cytokines produced by activated macrophages and T cells are implicated in arthritis pathogenesis and are involved in osteoclast-mediated bone resorption. The scope of the present review is to analyze current knowledge and to provide...
متن کاملBone destruction in multiple myeloma.
Multiple myeloma (MM) is characterized by accumulation of monoclonal plasma cells in the bone marrow and progression of lytic bone lesions. MM cells enhance bone resorption by triggering a coordinated increase in RANK ligand and decrease in osteoprotegerin in the bone marrow. Macrophage inflammatory protein (MIP)-1alpha and (MIP)-1beta are secreted by MM cells, and play a major role in the enha...
