IL-22 Induces an Acute-Phase Response

IL-22 induces an acute-phase response.

IL-22 is made by a unique set of innate and adaptive immune cells, including the recently identified noncytolytic NK, lymphoid tissue-inducer, Th17, and Th22 cells. The direct effects of IL-22 are restricted to nonhematopoietic cells, its receptor expressed on the surface of only epithelial cells and some fibroblasts in various organs, including parenchymal tissue of the gut, lung, skin, and li...

IL-22 Induces an Acute-Phase Response Associated to a Cohort of Acute Phase Proteins and Antimicrobial Peptides as Players of Homeostasis

Upon different external stimuli including bacteria and virus infection, and internal stimuli including both self-damaged products from trauma, burn injury, surgery, cancer mediated inflammatory disorders, exhausting exercises, child delivery and stroke as well as different immune diseases, an organism need to react in order to continuously preserve an equilibrated thermodynamic state, namely ho...

IL-21 induces IL-22 production in CD4+ T-cells

Interleukin (IL)-22 produced by innate lymphoid cells (ILCs) and CD4+ T cells plays an important role in host defence and mucosal homeostasis, thus it is important to investigate the mechanisms that regulate IL-22 production. We investigated the regulation IL-22 production by CD4+ T cells. Here we show that IL-21 triggers IL-22, but not IL-17 production by CD4+ T cells. STAT3, activated by IL-2...

IL-22 and IL-17: An Overview

Many studies from recent years have shown that cytokines like IL-22, IL-17A, and IL-17F play a major role in both the defense against certain microbes and the development and maintenance of chronic inflammatory diseases. These mediators are often secreted by subpopulations of T-helper cells called Th17 cells and Th22 cells, respectively. This chapter provides an overview about the common and di...
