Interleukin-10 Family Cytokines Immunobiology and Structure


Interleukin-10 Family Cytokines Immunobiology and Structure

Huaxing Wei et al. Adv Exp Med Biol. .


The Interleukin (IL)-10 cytokine family includes IL-10, IL-19, IL-20, IL-22, IL-24, and IL-26, which are considered as Class 2α-helical cytokines. IL-10 is the most important cytokine in suppressing pro-inflammatory responses in all kinds of autoimmune diseases and limiting excessive immune responses. Due to protein structure homology and shared usage of receptor complexes as well as downstream signaling pathway, other IL-10 family cytokines also show indispensable functions in immune regulation, tissue homeostasis, and host defense. In this review, we focus on immune functions and structures of different cytokines in this family and try to better understand how their molecular mechanisms connect to their biological functions. The molecular details regarding their actions also provide useful information in developing candidate immune therapy reagents for a variety of diseases.

Keywords: Class 2α-helical cytokines; IFN-λ; IL-19; IL-20; IL-22; IL-24; IL-26; Interleukine-10.
