IL-21 Regulates Creation of Tertiary Lymphoid Organs in Chronic Allograft Rejection
J. Breidenbach, C. Baum, P. Schroder, S. Stepkowski.
Medical Microbiology and Immunology, University of Toledo College of Medicine and Life Science, Toledo, OH.
Background: IL-21 is a cytokine expressed almost exclusively by cells of the adaptive immune system, making it an attractive target for reducing chronic allograft rejection…
