This volume provides a set of reviews dedicated to the biology of
Interleukin (IL)-10. It includes chapters on its importance for
maintaining immune homeostasis in humans, its role in intestinal
immunity and its functions during viral and bacterial infections. In
addition, it presents reviews on the mechanisms linking innate microbial
recognition to the production of IL-10 and on how IL-10 recognition by
its receptor functions. The roles of T and B cells as relevant sources
of IL-10 are also discussed, with an emphasis on the clinical
opportunities offered by IL-10-producing Tr1 cells for the suppression
of unwanted immunity. Finally, the functions of other cytokines of the
IL-10 family are presented. Collectively, these articles provide a
comprehensive overview of our current knowledge on one of the most
important anti-inflammatory cytokines known to date.
