Researchers at Tulane University have created a first-of-its-kind subcellular map of an area of the brain commonly affected by Alzheimer鈥檚 disease, a key step toward unraveling the mysteries of how the degenerative brain disease develops. The study illuminated the genetic mechanisms that cause the loss of brain cells that allow the disease to progress and identified a key protein as a potential target for treatment.

Among the subpopulations, researchers also found marked differences in health outcomes, socioeconomic status, education, and immigration status that can be easily obscured when these groups are characterized as a single population, the authors wrote. These differences challenge the presumption that gastrointestinal cancers affect each subpopulation similarly, said lead author Dr. Vicki Tang.

Newly funded research by the Patient-Centered Outcomes Research Institute (PCORI) will study 250 women over five years to find out how they fare after their diagnosis and the extent social support, or lack thereof, plays a part in their recovery and survival. The $6.8 million study will begin in September and continue through 2030.

WashU Medicine researcher Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology, has shown in mice that sperm have a temperature-controlled switch that changes their movements and is key to male fertility. The discovery sheds light on why mammals, including humans, have evolved to keep male reproductive organs cooler than their core body temperature.
