Weill Cornell Medicine investigators have identified in a preclinical model a specific brain circuit whose inhibition appears to reduce anxiety without side effects. Their work suggests a new target for treating anxiety disorders and related conditions and demonstrates a general strategy, based on a method called photopharmacology, for mapping drug effects on the brain.

Non-white communities had significantly less access to opioid medications commonly prescribed for moderate to severe pain than white communities over the decade beginning in 2011, according to a study by Weill Cornell Medicine researchers.

The overwhelming majority of those in New York City who obtained a naloxone kit to counteract opioid overdose had a high need for the drug, according to a new study by Weill Cornell Medicine investigators and the New York City Department of Health and Mental Hygiene.

Three Weill Cornell Medicine scientists were honored this week with the Presidential Early Career Award for Scientists and Engineers, the U.S. government’s highest commendation for outstanding early-career scientists and engineers.

A group of immune proteins called the inflammasome can help prevent blood stem cells from becoming malignant by removing certain receptors from their surfaces and blocking cancer gene activity, according to a preclinical study by Weill Cornell Medicine investigators.

Weill Cornell Medicine researchers have found that pharmacy benefit managers (PBMs)—organizations that negotiate access to medicines for most patients in the United States—steer patients to use their own pharmacies. However, these pharmacies appear less used in Medicare than in other market segments. These PBMs are part of integrated health care conglomerates that own insurance companies and pharmacies, which may create conflicts of interest.

Beneficial gut microbes and the body work together to fine-tune fat metabolism and cholesterol levels, according to a new preclinical study by investigators from Weill Cornell Medicine and the Boyce Thompson Institute at Cornell University’s Ithaca campus.

The hormone estrogen regulates binge drinking in females, causing them to “pregame”—consume large quantities of alcohol in the first 30 minutes after it’s offered, according to a preclinical study led by scientists at Weill Cornell Medicine. The study establishes, for what is thought to be the first time, that circulating estrogen increases binge alcohol consumption in females and contributes to known sex differences in this behavior.

Immune cells in the brain called microglia can partially break down large amyloid plaques characteristic of Alzheimer’s disease by latching on to them, forming a sort of external stomach and releasing digestive enzymes into the space, according to a preclinical study by Weill Cornell Medicine investigators. The findings could ultimately lead to therapies that boost the ability of microglia to break down amyloid plaques.
