Molecular and cellular basis of rheumatoid joint destruction

Abstract

Rheumatoid arthritis (RA) is a chronic inflammatory disease associated with joint destruction. Synovial fibroblasts are key players in this pathological process. They favorise a pro-inflammatory environment in the synovial tissue, interact with the immune system and regulate the differentiation of monocytes into osteoclasts. Synovial hyperplasia is another characteristic of RA, reflecting not only an imbalance between proliferation and apoptosis, but also the migration of cells into the synovial tissue. Gene transfer experiments have been used as important tools for the understanding of molecular and cellular changes that characterize the activated RA synovial fibroblasts. Activated synovial fibroblasts can invade cartilage and bone. Synovial activation is driven by cytokines, such as TNFalpha and IL-1, as well as IL-15, 16, 17, 18, 22, 23, but also by cytokine-independent mechanisms that involve the innate immune system (i.e. TLRs), a unique communication network of microparticles and epigenetic changes (e.g. L1 retroelements).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
