Decoding How a Viral Protein May Enable Safer Regenerative Cell Therapies

doctor

A new study from Weill Cornell Medicine uncovers how a viral protein called E4ORF1 precisely activates a specific signaling complex in human blood vessel cells to support cell survival. The preclinical findings, published November 13 in the Journal of Biological Chemistry, provide a blueprint for how this pathway can be controlled with molecular specificity—an advance that could help make regenerative cell therapies safer and more effective. “Our findings suggest it may be possible to design...

Loneliness Linked to Higher Risk of 30-Day Hospital Return After Heart Attack

student

People who felt lonely before having a heart attack were significantly more likely to end up back in the hospital within a month of discharge, according to findings by the researchers in the Division of General Internal Medicine at Weill Cornell Medicine. The study, published Dec. 2025 in the Journal of Medical Care, suggests that feeling lonely — independent of other health or social factors — can meaningfully affect recovery after a heart attack.

Loneliness is widespread, affecting...

ai

Drs. Shira Sachs, Madison Dennis and Justin Choi from the Division of General Internal Medicine at Weill Cornell Medicine received grants through its Clinical Reasoning Catalyst program. The initiative provides funding to implement DDx, an AI-powered clinical readiness platform that equips educators to deliver real-world, future-ready clinical reasoning training across every phase of medical education.

The awarded institutions: Yale School of Medicine, Weill Cornell Medicine, WashU...

Study Finds Heart Failure Training and Technology Support for Home Health Aides Improves Patient Care

doctor

Combining heart failure education with real-time communication tools can better equip home health aides (HHAs) to care for adults with heart failure in the home, according to a pilot randomized clinical trial conducted by researchers in the Division of General Internal Medicine at Weill Cornell Medicine and VNS Health, one of the largest home care agencies in the United States, located in New York City. The study, published in JAMA Network Open, was funded by National Heart, Lung, and Blood...

Organized by Dr. Myles Wolf, Chair, Dr. Kyu Rhee, Professor and Vice Chair of Research, and Dr. Gregory Sonnenberg, Professor and Associate Vice Chair of Research, this highly collaborative event will bring together a diverse range of established and emerging faculty, trainees, and experts in complementary fields to foster and expand the Department's research...

Galvanizing Blood Vessel Cells to Expand for Organ Transplantation

doctor

Scientists have discovered a method to induce human endothelial cells from a small biopsy sample to multiply in the laboratory, producing more than enough cells to replace damaged blood vessels or nourish organs for transplantation, according to a preclinical study by Weill Cornell Medicine investigators. Endothelial cells form the inner lining of blood vessels and regulate blood flow, inflammation and healing. Traditional approaches for growing these cells in the lab have yielded only...

Gut Neurons Help the Body Fight Inflammation

Neuron

Neurons in the gut produce a molecule that plays a pivotal role in shaping the gut’s immune response during and after inflammation, according to a new study by Weill Cornell Medicine investigators. The findings suggest that targeting these neurons and the molecules they produce could open the door to new treatments for inflammatory bowel disease and other disorders driven by gut inflammation.

Hundreds of millions of neurons make up the enteric nervous system, the “second brain” of the...
