Abnormal forms of a brain-cell protein called tau, which have long been implicated in Alzheimer’s and other neurodegenerative disorders, may contribute to neurodegeneration earlier than was previously understood, by interfering with the normal dynamics of blood flow in the brain, suggests a study from scientists at Weill Cornell Medicine. The results pave the way for research efforts that seek to prevent early neurodegeneration by restoring normal blood flow.

The short-term risk of a second stroke following an initial minor stroke is roughly 60 percent higher for black patients compared with white patients, according to a study led by Weill Cornell Medicine and NewYork-Presbyterian researchers.

In the study, published Feb. 24 in JAMA Neurology, the researchers re-analyzed the results of a stroke prevention trial conducted at 269 sites worldwide, including...

Immune cell activity in the brain differs between males and females in ways that may explain why some neurodegenerative diseases affect the sexes differently, according to a new study from Weill Cornell Medicine scientists.

The study, published Dec. 23 in Nature Neuroscience, compared brain-resident immune cells called microglia in male and female mice. Microglia in Alzheimer’s disease and other neurodegenerative disorders...

Weill Cornell Medicine scientists have built the first global database of clinical trials testing a rapidly expanding approach to cancer treatment that involves genetically modifying immune cells to recognize specific targets on a patient’s cancer cells and attack them. By analyzing the approach, called chimeric antigen receptor (CAR) therapies, the scientists designed a “therapeutic roadmap” that identifies all current therapies as well as additional cancers that can be treated with them....
