Lab Mission

Welcome to the Doloff Lab for Immunoengineering and Regenerative Medicine. Our mission is to explore the intersection between therapeutics, whether biologic or synthetic in origin, and living systems to better understand what happens when deliverables are introduced into the body and how the host immune system behaves as well as perceives them.

Drug crystals to prevent medical device fibrosis

Implanted medical devices can save lives, but can also put patients at the risk of fibrosis, a condition in which the immune system attacks the device and produces scar tissue around it, interfering with the device’s functionality. Working with researchers at Massachusetts Institute of Technology, Joshua Doloff, an assistant professor of biomedical engineering at Johns Hopkins University and former MIT postdoc, has devised a new way to prevent fibrosis: loading implantable devices with a crystallized immunosuppressant drug… continue reading

Study points a way to better implants

Medical devices implanted in the body for drug delivery, sensing, or tissue regeneration usually come under fire from the host’s immune system. Defense cells work to isolate material they consider foreign to the body, building up a wall of dense scar tissue around the devices, which eventually become unable to perform their functions… continue reading

Designing better medical implants

A team of researchers has come up with a way to reduce that immune-system rejection. In a study in Nature Materials, they found that the geometry of implantable devices has a significant impact on how well the body will tolerate them… continue reading
