It has been shown that inflammatory cytokines cause an IL-10-dependent inhibition of [24] T-cell expansion and function by up-regulating PD-1 levels on monocytes, which leads to IL-10 production by monocytes after binding of PD-1 by PD-L. [24] Adverse reactions to cytokines are characterized by local inflammation and/or ulceration at the ...
CCL2 is a small cytokine that belongs to the CC chemokine family. CCL2 tightly regulates cellular mechanics [5] and thereby recruits monocytes, memory T cells, and dendritic cells to the sites of inflammation produced by either tissue injury or infection. [6] [7]
The lysosome contains enzymes and acids that kill and digest the particle or organism. In general, phagocytes patrol the body searching for pathogens, but are also able to react to a group of highly specialized molecular signals produced by other cells, called cytokines. The phagocytic cells of the immune system include macrophages, neutrophils ...
Oncostatin M, also known as OSM, is a protein that in humans is encoded by the OSM gene. [5] OSM is a pleiotropic cytokine that belongs to the interleukin 6 group of cytokines. [6] Of these cytokines it most closely resembles leukemia inhibitory factor (LIF) in both structure and function. [6]
An inflammatory cytokine is a type of cytokine (a signaling molecule) that is secreted from immune cells and certain other cell types that promotes inflammation. Inflammatory cytokines are predominantly produced by T helper cells ( T h ) and macrophages and involved in the upregulation of inflammatory reactions. [ 1 ]
Other properties attributed to the cytokine include: the growth promotion and cell differentiation of different types of target cells, influence on bone metabolism, cachexia, neural development, embryogenesis and inflammation. p53 regulated LIF has been shown to facilitate implantation in the mouse model and possibly in humans. [5]
Human retinal pigmented epithelial (RPE) cells can also be engineered to express a cytokine of interest. RPE cells are ideal cytokine delivery systems because they are nontumorigenic, display contact inhibition, are amenable to genetic modification, have bene previously used in human trials for therapeutic delivery systems, and are safe to use.

Interleukin 10 (IL-10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine. In humans, interleukin 10 is encoded by the IL10 gene. [ 5 ] IL-10 signals through a receptor complex consisting of two IL-10 receptor-1 and two IL-10 receptor-2 proteins. [ 6 ]
