IL-6R Blockade with Tocilizumab Increases Tregs and Decreases Early Graft Inflammation in Kidney Transplant Recipients: Results of a Randomized Controlled Trial
S. Chandran, J. Leung, Z. Laszik, Q. Tang, C. Hu, M. Joanes, F. Vincenti
UCSF, San Francisco, CA
*Purpose: IL-6, a proinflammatory cytokine and key regulator of Treg/Th17 balance, is strongly associated with renal graft rejection. We hypothesized that IL-6 blockade with tocilizumab…
