Scientists discover genetic switch to prevent neurodegenerative diseases

Scientists at Northwestern University report a surprising discovery that offers a possible new route for the treatment of neurodegenerative diseases. In a study of the transparent roundworm C. elegans, they found that a genetic switch in master neurons inhibits the proper functioning of protective cell stress responses, leading to the accumulation of misfolded and damaged proteins.

Scientists discover mutant hypertension gene in chickens similar to that of humans

Scientists from the University of Abertay Dundee have discovered that a gene which, when severely mutated, causes blindness and kidney abnormalities in chickens, is the same as one that predisposes humans to hypertension.

Study finds novel small molecule that inhibits EboV entry into host cells

Ebola virus (EboV) is the cause of sporadic outbreaks of highly fatal infections in Africa that are unpredictable in onset and rapid in progression. There is no effective vaccine or therapy for EboV infection.

Scientists define specific protein complex that allows cells to remove damaged mitochondria

In a joint research effort with researchers at St. Jude Children's Research Hospital, and with help from scientists at The University of Pennsylvania, The University of Minnesota, and the National Institutes of Health, investigators from the Florida campus of The Scripps Research Institute have defined a specific protein complex that allows cells to rid themselves of damaged mitochondria, which are the energy producing machines of the cell.

Study finds biological indicators that help explain why obese people develop chronic diseases

UC Davis Health System researchers have discovered biological indicators that help explain why some obese people develop chronic diseases such as diabetes and heart disease, and others do not.

Researchers reveal specific process by which HIV virus infects healthy T cells

A George Mason University researcher team has revealed the specific process by which the HIV virus infects healthy T cells-a process previously unknown. The principal investigator, HIV researcher Yuntao Wu, says he hopes this breakthrough will start a new line on inquiry into how researchers can use this knowledge to create drugs that could limit or halt HIV infection.

Scientists identify critical protein responsible for Ebola virus infection

In separate papers published online in Nature, two research teams report identifying a critical protein that Ebola virus exploits to cause deadly infections. The protein target is an essential element through which the virus enters living cells to cause disease.

New mouse brain atlas provides insight into how genes work in cerebral cortex

A new atlas of gene expression in the mouse brain provides insight into how genes work in the outer part of the brain called the cerebral cortex. In humans, the cerebral cortex is the largest part of the brain, and the region responsible for memory, sensory perception and language.
