WebCombinations of platelet derived cytokines were the most potent stimulators of DNA synthesis, while combinations of synovial derived cytokines were more active in stimulating GAG synthesis. Synovial cells exposed simultaneously to both platelet and synovial derived cytokines produced large quantities of [14C]GAG and showed a modest increase in ... WebBy controlling DC activation, cytokines regulate immune homeostasis and the balance between tolerance and immunity. The increased production and/or bioavailability of cytokines and associated alterations in DC homeostasis have been implicated in various human inflammatory and autoimmune diseases.

Cytokines and their Role in Health and Disease: A Brief Overview
WebAug 1, 2015 · Cytokines are proteins produced and secreted by a variety of cells including stromal cells, fibroblasts, and endothelial cells. In the immune system they are produced by leukocytes and exert their function on other leukocytes or tissues that express the cytokine receptor [28]. Some of them are called interleukins (between leukocytes). WebIL-8 is a chemoattractant cytokine with a distinct target specificity for the neutrophil and is produced by a variety of tissues and blood cells . IL-8 also supports cell homing and … WebThe cytokine secreted by one cell type activates a second cell type; the second cell type, in turn, secretes a cytokine that acts on another cell type.
