Use of IL35 to convert T-cells to Regulatory T-cells (SJ-09-0024)



Technology Name
(St. Jude Reference #)		 Use of IL35 to convert T-cells to Regulatory T-cells
(SJ-09-0024)
Description

We have discovered that IL-35 can be used to induce the conversion of conventional CD4+ T-cells into induced regulatory T-cells that have potent suppressive capacity in vitro and in vivo.  These cells have been designated iTr35 cells by the inventors.  This approach can be used to generate regulatory T-cells to treat autoimmune and inflammatory diseases, such as (but not limited to) type 1 diabetes, MS, arthritis, asthma and allergic diseases, IBD, etc.    
Keywords regulatory T-cells, autoimmune; IL-35, iTr35 cells
Granted Patents or Published Applications UInternational application pending; should publish in September of 2010.
