Revising the meaning of “prion”

Prions are infamous for causing Creutzfeld-Jakob disease, fatal familial insomnia, and bovine spongiform encephalopathy, commonly known as mad cow’s disease. Yet, it’s not likely that’s all they’re good for. Using an unbiased screen in yeast, a team of Whitehead Institute and Stanford University scientists have identified dozens of prion-like proteins that could change the defining characteristics of these unusual proteins.

Derived neural immune cells enable new facet of neurodegeneration research

Whitehead Institute scientists have devised a protocol for pushing human pluripotent stem cells to become microglia—the specialized immune cells that maintain the brain and care for it after injury. Microglia play an important role in neurodegenerative diseases, including Parkinson’s and Alzheimer’s, and studying these cells has been very difficult until now.

Scientists use CRISPR/Cas9 to flip DNA methylation states in vivo

Whitehead Institute scientists have deciphered how to use a modified CRISPR/Cas9 gene editing system to change genes’ methylation state, thereby activating or silencing those genes. Proper methylation is critical for normal cellular operations and altered methylation has been linked to many diseases, including neurological disorders and cancer.

Inherited parental methylation shifts over time, may have functional effects in the brain and other tissues

Inherited methylation—a form of epigenetic regulation passed down from parents to offspring—is far more dynamic than previously thought and may contribute to changes in the brain and other tissues over time. This finding by Whitehead Institute scientists challenges current understandings of gene regulation via methylation, from development through adulthood.
