Treating autoimmune and inflammatory diseases with enhanced regulatory T-cells

Interleukin-2 (IL-2) is the main cytokine supporting regulatory T-cells (Tregs) development, survival and suppressive activity. However, Tregs cannot produce IL-2 and fully depend on exogenous IL-2. Treg cell therapy products are grown for weeks in culture medium containing IL-2 concentration that a...

520 |a Interleukin-2 (IL-2) is the main cytokine supporting regulatory T-cells (Tregs) development, survival and suppressive activity. However, Tregs cannot produce IL-2 and fully depend on exogenous IL-2. Treg cell therapy products are grown for weeks in culture medium containing IL-2 concentration that are 10 000-fold higher than the IL-2 serum concentration in humans. This generates "IL-2 addicted" Tregs that might not survive well and/or function optimally when reinjected in patients. We reasoned that Tregs that could produce their own IL-2 would have markedly improved therapeutic potential. ... Altogether, we believe that Treg cell products should be supported by IL-2 after injection to patients. This could be done by injecting low-dose IL-2 or advantageously by an autocrine production of IL-2 that dramatically improves the therapeutic potential of Tregs. This approach could be introduced in any form of Treg cell therapy, from polyclonal Tregs to antigen specific or targeted Tregs
