Immunologic Impact of Tocilizumab Treatment in Kidney Transplant Recipients with Allograft Inflammation
J. Leung, S. Chandran, F. Vincenti, Q. Tang.
UCSF, San Francisco.
Background: Proinflammatory cytokine IL-6 increases effector/memory T-cells, induces Th17 cells and prevents the induction of Tregs. IL-6 expression in kidney biopsies is elevated during acute…
