The present invention provides methods and compositions for the use of IL-22 for treating conditions of intestinal injury and inflammatory conditions such as graft vs. host disease. Specifically, IL-22 can be used to increase Intestinal Stem Cell (ISC) recovery and for enhancing immune reconstitution following allogeneic hematopoietic transplantation. In particularly preferred embodiments, the present invention provides methods of using therapeutic IL-22, including a dimeric form of IL-22, in therapeutic compositions for treating graft vs. host disease, including hepatic, thymic, gastrointestinal, or other graft vs. host disease in hematopoietic stem cell transplant patients and in patients with inflammatory intestinal conditions.

The present invention provides methods and compositions for the use of IL-22 to promote thymic growth following thymic insult. In particularly preferred embodiments, the present invention provides methods of using therapeutic IL-22 compositions for treating patients with thymic atrophy and alterations in bone marrow derived white blood cells, including cancer patients undergoing chemotherapy, patients exposed to radiation (i.e. cancer therapy, nuclear disaster, terrorist attack, etc.), patients with HIV infections/AIDS, patients with organ transplantation, aging patients, and the like. In a further embodiment, therapeutic IL-22 compositions are contemplated as a prophylactic to boost immune response when additional T-cell function is needed, i.e. to boost immune response during vaccination.
