What to know about Nanotechnology

Researchers from Sungkyunkwan University and the University of Michigan have developed an oral nanomedicine that uses a gut bacterial metabolite, DHB, to enhance the effectiveness of cancer immunotherapy. The study, published in Nature Nanotechnology, demonstrates that the treatment improves T cell activity and, in animal models, can lead to tumor shrinkage and eradication when combined with other therapies.

What happened

Oral nanomedicine improves cancer immunotherapy by harnessing gut bacterial metabolite Sadie Harley Scientific Editor Robert Egan Senior Editor A joint research team—led by professor Young Seok Cho from the School of Medicine, alongside professor James J.

Why it matters

Moon from the University of Michigan—has developed the world's first oral, microbiome-based nanomedicine.

Common ground

By leveraging natural metabolites produced by gut bacteria, the new drug significantly enhances immune cells' ability to attack cancer cells.
