IL-19 is involved in the pathogenesis of endotoxic shock.

IL-19, a proinflammatory cytokine, belongs to the IL-10 family. IL-19 is induced in systemic inflammatory response syndrome, but its pathophysiological function in sepsis is unclear. Our aim was to determine the roles of IL-19 in endotoxin-induced tissue damage in vivo and in vitro.

Expression of IL-19 correlates with Th2 cytokines in uraemic patients.

Background: Patients with end-stage renal disease are thought to be in a chronic state of inflammation. They also have an impaired immune response with a dysregulated Th1/Th2 cytokine network. Interleukin (IL)-19, which belongs to the IL-10 family, is a newly discovered proinflammatory cytokine.

Tissue microarray analysis of interleukin-20 expression.

Knowledge about the biological functions and clinical implications of interleukin (IL)-20, a recently discovered cytokine in the IL-10 family, is still incomplete. Our aim was to determine the distribution of IL-20 expression and to delineate the cell types that express IL-20 in healthy and neoplastic tissue, because this information will significantly affect the exploration of its pathophysiological roles. We used tissue microarray technology and an immunohistochemical survey using an anti-IL-20 monoclonal antibody to examine IL-20 expression in 36 non-neoplastic and 14 neoplastic tissues.
