Secretion of plasminogen activator by rheumatoid and nonrheumatoid synovial cells in culture. 1977

H Berger

The secretion of plasminogen activator by human synovial cultures established from explants was studied. Thirteen cultures established from patients with rheumatoid disease were hyposecretors of plasminogen activator. Seven cultures derived from patients with nonrheumatoid joint disorders all secreted high levels of this enzyme. Rheumatoid and nonrheumatoid cells contained comparable levels of intracellular activator. It is suggested that the secretion of plasminogen activator is a function of normal synovium and that a defect in this function in the rheumatoid synovium perpetuates the inflammatory process.

D007700	Kinetics	The rate dynamics in chemical or physical systems.
D010960	Plasminogen Activators	A heterogeneous group of proteolytic enzymes that convert PLASMINOGEN to FIBRINOLYSIN. They are concentrated in the lysosomes of most cells and in the vascular endothelium, particularly in the vessels of the microcirculation.

D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture

D001172	Arthritis, Rheumatoid	A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.	Rheumatoid Arthritis
D013583	Synovial Membrane	The inner membrane of a joint capsule surrounding a freely movable joint. It is loosely attached to the external fibrous capsule and secretes SYNOVIAL FLUID.	Synovium,Membrana Synovialis Capsulae Articularis,Membrane, Synovial,Membranes, Synovial,Synovial Membranes
