Recipient Conditioning Results in IL-33 Support of Potent Th1 Alloimmune Responses after CD4⁺ T Cells Upregulate ST2 during Lymphopenia Induced Proliferation
G. Dwyer,¹ L. Mathews,¹ A. Lucas,¹ B. Blazar,² H. Turnquist.¹
¹Starzl Transplantation Institute and Department of Surgery, University of Pittsburgh School of Medicine, Pittsburgh, PA; ²Department of Pediatrics, University of Minnesota, Minneapolis, MN.
Purpose: IL-33 is typically associated with support of Th2 and Treg responses. Yet, recipient conditioning before allogeneic hematopoietic cell transplantation (alloHCT) releases IL-33 to promote…

A Novel Conditioning Approach to Establish Chimerism Using Manipulation of JAK-STAT Pathways
H. Xu, A. Merchak, L. Kahn, A. Chhabra, Y. Wen, Y. Huang, S. Ildstad.
Institute for Cellular Therapeutics, University of Louisville, Louisville, KY.
Hematopoietic chimerism establishes donor-specific tolerance to solid organ allografts. Targeting recipient immune cells (T, NK cells and macrophages) can effectively reduce the dose of total…
