In a collaboration with immunologist and Washington University professor Emil Unanue and his colleagues, researchers at J&J's Janssen Pharmaceuticals will explore how specific immune system cells are involved in the initiation and progression of Type 1 diabetes.
The disease, also called juvenile diabetes, affects about 5 per cent of Americans with diabetes, roughly 1.25 million people. For reasons that aren't clear, the immune system attacks and destroys beta cells in the pancreas that make the hormone insulin, which is needed to convert blood sugar into energy.
"We hope to be able to manipulate the (immune) system in such a way that this no longer drives the destruction of beta cells, while maintaining protection against infections and tumors," said Joseph A Hedrick, leader of that project.
Hedrick noted the findings might help in fighting other autoimmune diseases, including psoriasis and rheumatoid arthritis.
The project is among 17 new collaborations with academic researchers and health care companies announced early today by Johnson & Johnson, which is based in New Brunswick, New Jersey.
Created by J&J partner Emulate Inc. Of Cambridge, Massachusetts, these microenvironments are designed to mimic responses of organs such as the liver or lungs as drugs flow through the chips' tiny hollow channels, which are lined with living human cells and tissues. The chips simulate the responses of cells to medicines or chemicals, from beneficial results to toxic reactions.
