About the Comparative Immunotherapy Program


The comparative immunotherapy program actively fosters and supports interdisciplinary collaborations and partnerships across departments and schools within the University of Pennsylvania and beyond, that engage in comparative translational research. The program leverages the depth and breadth of expertise of faculty, particularly in the fields of immunobiology and immunotherapy, to expedite the translation of safe and effective cutting edge treatments for both companion animals and their humans. Programs within the program include organ transplantation, autoimmunity and inflammation, immuno-oncology and infectious disease.
