Cutting Edge: IL-2 Signals Determine the Degree of TCR Signaling Necessary To Support Regulatory T Cell Proliferation In Vivo. Zou T, Kambayashi T. et al. J Immunol. 2012 Jul 1;189(1):28-32. It has been thought that proliferation of T regulatory cells in vivo was dependent on signaling from T cell receptor –MHC Class II interaction. Zou

“Human Th17 Cells Express High Levels of Enzymatically active Dipeptidylpeptidase IV (CD26)” Bengsch B, R Thimme, et al, (2012) J Immunol 188(11): 5438-5447. In transwell assays, CD26(bright) Th17 cells inhibited chemotaxis of CXCR4+ Th1 T cells towards CXCL12. CD26 appears to be an interesting and useful marker for Th17 autoimmunity. Ancell anti-CD26 reagents (clone 202.36):

Transplanted islet cells were biochemically modified to protect their own long term engraftment in a mouse pancreas. These cells have the super-ability to cause apoptosis to occur in the infiltrating pathogenic T cells. This is a novel approach to diabetes treatment! ”Pancreatic Islets Engineered with SA-FasL Protein Establish Robust Localized Tolerance by Inducing Regulatory T
