In addition, subjects #1, 2 and 3 will repeat the leukapheresis (under a separate protocol) and undergo Treg infusions at the modified schedule of every 4 weeks, with concomitant subcutaneous injections of IL-2 (2 x 105 IU/m2) 3 times weekly. The subjects will be called on Day 7, and 21. Office visits will be completed on the day after infusions and every two weeks while the subjects are undergoing Treg infusions for clinical evaluation, scoring, and blood draws. The subjects will then be seen during office visits once per month for one year total from their initial baseline visit for clinical evaluation, scoring, and blood draws
