Light microscopic characterization of the fibroblast-like synovial intimal cell (synoviocyte)

Fibroblast-like synoviocyte metabolism in the pathogenesis of rheumatoid arthritis

An increasing number of studies show how changes in intracellular metabolic pathways alter tumor and immune cell function. However, little information about metabolic changes in other cell types, including synovial fibroblasts, is available. In rheumatoid arthritis (RA), fibroblast-like synoviocytes (FLS) are the most common cell type at the pannus-cartilage junction and contribute to joint des...

Building 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 ...

Fibroblast-like synoviocyte-chondrocyte interaction in cartilage degradation.

OBJECTIVE In vitro models for joint diseases often focus on a single cell type, such as chondrocytes in osteoarthritis (OA) or fibroblast-like synoviocytes (synoviocytes) in rheumatoid arthritis (RA). However, these joint diseases affect the whole joint and interaction between chondrocytes and synoviocytes may play an important role in disease pathology. The current study was designed to study ...

[Synoviocyte cultures from synovial fluid].

UNLABELLED The study of the pathogenetic mechanisms of rheumatic diseases is in general carried out through "in vitro" systems based on cellular cultures models. The difficulties to achieve fresh human tissue prompted us to develop a simpler method to obtain fibroblast-like synovial cells from synovial fluid (SF). METHODS SF was collected from the knees of 5 patients with rheumatoid arthritis...
