A protein induced by gut microbes is vital in healing colons that have become inflamed due to a short-term form of colitis, Weill Cornell Medicine researchers discovered in a new study. However, they also found that this molecule, called TNF-like ligand 1A (TL1A) contributes to the sustained inflammation characterized by chronic inflammatory bowel disease (IBD).

In a study published Dec. 11 in Immunity,...

Common drug treatments that lead to changes in gut fungi can persistently exacerbate allergic airway diseases such as asthma, according to a study by Weill Cornell Medicine researchers.

The study, published online Nov. 29 in Cell Host & Microbe, suggests that the enormous modern prevalence of allergic airway diseases may be attributable in part to the widespread use of antimicrobials, including...

Weill Cornell Medicine has been awarded a five-year, $9 million Program Project Grant (P01) from the National Cancer Institute (NCI) to better understand how and why patients with an aggressive and incurable form of lymphoma initially respond to treatment, only to relapse over time. The findings may enable investigators to develop superior therapies that are effective, well tolerated and tailored to individual patients with mantle cell lymphoma.

The NCI, part of the National...

Scientists can now discover how the fine details of gene activity differ from one cell type to another in a tissue sample, thanks to a technique invented by Weill Cornell Medicine researchers.

The technique, described in a paper published Oct. 15 in Nature Biotechnology, will enable biologists to better understand the distinct molecular workings of different cell types in the body. It may also enable the improved understanding and...
