Digging Into a Decades-Old Hepatitis B Mystery Suggests a New Potential Treatment

In their effort to answer a decades-old biological question about how the hepatitis B virus (HBV) is able to establish infection of liver cells, research led by Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center (MSK) and The Rockefeller University identified a vulnerability that opens the door to new treatments.

The team successfully disrupted the virus’s ability to infect human liver cells in the laboratory using a compound already in clinical trials against cancer — laying the groundwork for animal model studies and potential drug development based on their insights, according to findings published Feb. 20 in Cell.

New Therapy May Effectively Control HIV in Uganda

HIV replicating

A multi-national, multi-institutional study led by Weill Cornell Medicine investigators found little natural resistance to a new HIV therapy called lenacapavir in a population of patients in Uganda.

The study, published Jan. 30 in the Journal of Antimicrobial Chemotherapy, adds to growing evidence that lenacapavir may be a powerful new tool in the global anti-HIV drug arsenal. Approximately, 1.5 million people are living with HIV in Uganda.

“Our data shows that only 1.6% of the individuals studied are living with HIV strains that have any known lenacapavir-associated resistance mutations,” said senior author Dr. Guinevere Lee, assistant professor of virology in medicine at Weill Cornell Medicine. “That’s important because it shows lenacapavir is likely to be effective against strains of HIV circulating in East Africa.”

Brain Bleeds Increase the Risk of Dementia

dementia and hemorrhage

Weill Cornell Medicine researchers have found that intracranial hemorrhages, or "brain bleeds" caused by a ruptured blood vessel in the brain, double a person’s risk of developing dementia later in life.

While the connection between dementia and ischemic strokes caused by clots that block blood supply to the brain has received more attention, the new study, published Jan. 30 in Stroke, extends previous findings to hemorrhages.
