22 Again: IL-22 as a Risk Gene and Important Mediator in Psoriasis

Serum Levels of IL-10 and IL-22 Cytokines in Patients with Psoriasis

Background: As a chronic inflammatory condition, psoriasis results from an interaction between genetic and immunologic factors in a predisposing environment. In spite of compelling evidence for the role of T cells and cytokines in psoriasis, interleukin (IL)- 10 and IL-22 have not been sufficiently investigated. Objective: To assess the serum levels of IL-10 and IL-22 in patients with psori...

IL-22 vs. IL-22: The Tissue Matters

IL-22 is a cytokine recently discovered to be produced by TH17 cells. Its receptor is expressed in the skin, liver, the digestive and the respiratory tract where IL-22 conveys signals of the immune system directly to the tissue. IL-22 is involved in the host defense against extracellular pathogens as well as in autoimmune inflammatory diseases and exerts, depending on the tissue and inflammator...

A new player on the psoriasis block: IL-17A- and IL-22-producing innate lymphoid cells

Innate lymphoid cells (ILCs) are a recently discovered family of innate immune cells belonging to the lymphoid lineage, yet lacking antigen-specific receptors. ILCs were first identified in the intestinal tract, where they contribute to epithelial barrier integrity and host responses to commensal microbes. Teunissen et al. (in the current issue) and Villanova et al. (2014) now suggest an import...
