Toll-Like Receptor 4–Induced IL-22 Accelerates Kidney Regeneration

Toll-like receptor 4-induced IL-22 accelerates kidney regeneration.

AKI involves early Toll-like receptor (TLR)-driven immunopathology, and resolution of inflammation is needed for rapid regeneration of injured tubule cells. Notably, activation of TLRs also has been implicated in epithelial repair. We hypothesized that TLR signaling drives tubule regeneration after acute injury through the induction of certain ILs. Systematic screening in vitro identified IL-22...

Toll-Like Receptor 4 and Toll-IL-1 Receptor

Interleukin-22 in kidney injury and regeneration.

Interleukins have become well-known regulators of innate and adaptive immunity-related tissue inflammation. Recently, IL-22 has gained a lot of interest for its unique functions in maintaining and regaining epithelial integrity. IL-22 is exclusively secreted by different immune cell subsets, while IL-22 receptors are mainly expressed by epithelial cells. As the kidney is largely an epithelial o...

Inhibition of IL-10 receptor function in alveolar macrophages by Toll-like receptor agonists.

Despite an immunosuppressive lung environment, alveolar macrophages (AM) retain the capacity to respond to microorganisms. This report demonstrates that IL-10, constitutively produced by normal alveolar epithelium, stimulates signal transduction through the IL-10R on AM and that IL-10R function can be inhibited by stimulation of Toll-like receptor (TLR) on AM. IL-10 mRNA and protein were consti...
