Adrenomedullin increases fibroblast-like synoviocyte adhesion to extracellular matrix proteins by upregulating integrin activation
INTRODUCTION Rheumatoid arthritis (RA) is characterized by bone and cartilage invasion by fibroblast-like synoviocytes (FLSs). Adrenomedullin, a peptide with anabolic and antiapoptotic properties, is secreted by rheumatoid FLSs. Adrenomedullin also increases the expression of adhesion molecules in endothelial cells and keratinocytes. Here, we investigated whether adrenomedullin mediated FLS adh...
متن کاملA critical role for adrenomedullin-calcitonin receptor-like receptor in regulating rheumatoid fibroblast-like synoviocyte apoptosis.
Rheumatoid arthritis (RA) is characterized by fibroblast-like synoviocyte (FLS) hyperplasia, which is partly ascribable to decreased apoptosis. In this study, we show that adrenomedullin (ADM), an antiapoptotic peptide, is constitutively secreted in larger amounts by FLS from joints with RA (RA-FLS) than with osteoarthritis (OA-FLS). ADM secretion was regulated by TNF-alpha. Peptidylglycine alp...
متن کاملAdhesion of human trabecular meshwork cells to extracellular matrix proteins. Roles and distribution of integrin receptors.
PURPOSE To examine the adhesion of human trabecular meshwork cells with various extracellular matrix (ECM) proteins and to evaluate the roles and distribution of integrin receptors. METHODS Cultured human trabecular meshwork cells were added to 96-well plates either uncoated or coated with proteins including fibronectin, laminin, and vitronectin, as well as collagen types I, III, IV, V, and V...
متن کاملThe neural cell adhesion molecule L1 potentiates integrin-dependent cell migration to extracellular matrix proteins.
The L1 adhesion molecule regulates axon growth and is mutated in the X-linked mental retardation syndrome CRASH (acronym for corpus callosum agenesis, retardation, aphasia, spastic paraplegia, hydrocephalus). A novel role for L1 as a potentiator of neuronal cell migration to extracellular matrix proteins through beta1 integrins and intracellular signaling to mitogen-activated protein (MAP) kina...
متن کاملBuilding the synovium: cadherin-11 mediates fibroblast-like synoviocyte cell-to-cell adhesion
Specific adhesion among like cells is a key determinant of the architecture of tissues. Homophilic (like binds like) adhesive interactions between cells are mediated by cadherins. These integral membrane glycoproteins have a crucial role in tissue morphogenesis during development and the maintenance of tissue integrity in adults. There is also an increasing recognition of a regulatory role for ...
