BACKGROUND Astrocytes, which comprise ~90% of overall brain mass, are involved in brain immunity. These cells represent the non-professional class of CNS-resident APCs and may promote or inhibit CNS inflammation depending on the cytokines they secrete. IL-10 family of cytokines and their receptors, IL-20R1 and IL-20R2, may have a role in shifting astrocytes to a neuroprotective or neurodegenera...

The receptor for IL-26 (AK155), a cytokine of the IL-10 family, has not previously been defined. We demonstrate that the active receptor complex for IL-26 is a heterodimer composed of two receptor proteins: IL-20R1 and IL-10R2. Signaling through the IL-26R results in activation of STAT1 and STAT3 which can be blocked by neutralizing Abs against IL-20R1 or IL-10R2. IL-10R2 is broadly expressed o...

objective: astrocytes are the most abundant glial cell type. they may promote or inhibit cns inflammation depending on which cytokines are secreted. astrocytes also have immune roles. il-19, il-20, and il-24 activate a heterodimer receptor composed of the il-20r1 α-chain and the il-20r2 β-chain. it has long been considered that signaling by these receptor complexes affects immunological reactio...

OBJECTIVE Atherosclerosis is a chronic inflammatory disease with immune cell infiltration. Various cytokines and chemokines have been characterized as pro- or antiatherogenic factors. Interleukin-20 (IL-20) belongs to the IL-10 family and is a proinflammatory cytokine involved in the pathogenesis of psoriasis. However, the association between IL-20 and atherosclerosis is undetermined. Therefore...

Interleukin 20 (IL-20) is a pleotropic IL-10 family cytokine that protects epithelial surfaces from pathogens. However, dysregulated IL-20 signaling is implicated in several human pathologies including psoriasis, rheumatoid arthritis, atherosclerosis, and osteoporosis. IL-20, and related cytokines IL-19 and IL-24, designated IL-20 subfamily cytokines (IL-20SFCs), induce cellular responses throu...

The soluble extracellular domains of human interleukin-20 (IL-20) receptors I and II (sIL-20R1 and sIL20R2), along with their ligands IL-19 and IL-20, were expressed in Drosophila S2 cells and purified to homogeneity. Formation of the receptor/receptor and ligand/receptor complexes was studied by size exclusion chromatography. Both ligands and soluble receptors were found to be monomeric in sol...
