Cancers often release molecules into the bloodstream that pathologically alter the liver, shifting it to an inflammatory state, causing fat buildup and impairing its normal detoxifying functions.

People with dementia have protein build-up in astrocytes that may trigger abnormal antiviral activity and memory loss.

The activity of a gene called CIART is a key factor in the establishment of the viral infection that causes COVID-19.

SARS-CoV-2 infections of women in late pregnancy frequently spread to their placentas and led to inflammation.

The SARS-CoV-2 virus can infect specialized pacemaker cells that maintain the heart’s rhythmic beat, setting off a self-destruction process within the cells, according to a preclinical study co-led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and NYU Grossman School of Medicine.

Researchers at Weill Cornell Medicine have identified a key protein that induces the program to build specialized liver blood vessels. The discovery could lead to engineered replacement hepatic tissue to treat common liver diseases.

Two Weill Cornell Medicine physician-scientists, Dr. Randy Longman and Dr. Robert Schwartz, have been elected as members of the American Society for Clinical Investigation.

An FDA-approved drug that has been in clinical use for more than 70 years may protect against lung injury and the risk of blood clots in severe COVID-19 and other disorders that cause immune-mediated damage to the lungs.

COVID-19 may bring high risks of severe disease and death in many patients by disrupting key metabolic signals and thereby triggering hyperglycemia, according to a new study from researchers at Weill Cornell Medicine and NewYork-Presbyterian. 

SARS-CoV-2, the virus causing the global COVID-19 pandemic, can infect human pancreatic cells and alter their physiology.

The heart damage seen in many severely ill COVID-19 patients results in part from infection-activated immune cells called macrophages, which infiltrate the heart and secrete cell-damaging chemicals, according to a study co-led by researchers at Weill Cornell Medicine, NewYork-Presbyterian, Icahn School of Medicine at Mount Sinai and Columbia University Irving Medical Center.

Two distinct diagnostic tests, a host/pathogen RNA sequencing platform, and spatially-resolved tissue mapping tools were created by a multidisciplinary team of Weill Cornell Medicine and NewYork-Presbyterian Hospital-led researchers and used to map SARS-CoV-2 infections at the height of the initial COVID-19 outbreak in New York City.

A team led by investigators at Weill Cornell Medicine and NewYork-Presbyterian has used advanced technology and analytics to map, at single-cell resolution, the cellular landscape of diseased lung tissue in severe COVID-19 and other infectious lung diseases.

Human organoids, tiny organ-like structures grown in the laboratory, can be used to identify potential COVID-19 drugs in an automated, high-throughput fashion.

A team led by Weill Cornell Medicine scientists has pioneered a method for manufacturing functioning human blood vessels and demonstrated that they can carry blood in lab-grown model organs and tumors.

The study of human pluripotent stem cells, which can develop into any cell type in the body, is providing Weill Cornell Medicine and NewYork-Presbyterian investigators with new insights into the virus that causes COVID-19 and how it may infect organs such as the pancreas and liver.

An understudied type of liver cell may drive scarring in liver disease and could be a promising target for new treatments, suggests a new study by Weill Cornell Medicine investigators.

Physicians and scientists at Weill Cornell Medicine and NewYork-Presbyterian have rapidly mobilized to confront the COVID-19 pandemic, focusing a broad spectrum of expertise on the critical issues the disease is posing to healthcare workers and public health officials.

Consuming a high-fat, high-sugar diet causes a harmful accumulation of fat in the liver that may not reverse even after switching to a healthier diet, according to a new study by scientists from Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center.
