CUL5: The Brain’s Garbage Collector That Clears Toxic Tau and Shields Neurons
New Discovery: A Brain Cleanup Crew Called CUL5 Scientists at the University of California, San Francisco, have identified a cellular mechanism that acts like a waste collector in the brain. The protein CUL5 appears to help neurons dispose of toxic tau clumps, which are a hallmark of several neurodegenerative diseases and a major driver of…

Brain Guardian: How CUL5 Clears Tau Clumps to Protect Neurons
Overview: A New Player in the Brain’s Waste Management In a landmark study from UC San Francisco, scientists have identified a crucial cellular picker-upper in the brain—CUL5—that helps clear toxic tau clumps. These clumps are notorious for driving neurodegenerative diseases and dementia. By acting as a molecular garbage collector, higher levels of CUL5 in neurons…

How CUL5 Protects Neurons by Clearing Toxic Tau Clumps
New Discovery: CUL5 as a Cellular Garbage Collector Neurons face daily threats from misfolded proteins that can aggregate into toxic clumps. In recent research from the University of California, San Francisco, scientists have identified a crucial player in the brain’s defense against these harmful tau clumps: a protein known as CUL5. This discovery positions CUL5…

Overactive Protein Cleanup Disrupts Nuclear Pores in Neurodegenerative Disease
New insights into the proteostasis puzzle in neurodegenerative disease Scientists are piecing together how cellular cleanup crews, tasked with maintaining protein quality, can sometimes backfire and threaten essential structures in the cell. In particular, excessive or misregulated protein degradation processes appear to disrupt nuclear pores, the gateways that regulate traffic between the nucleus and the…

Majority of Alzheimer’s Risk Tied to a Single Gene Variant
Groundbreaking Link Between Gene Variant and Alzheimer’s Risk A new study published in npj Dementia reports a striking association between a specific gene variant and Alzheimer’s disease risk, suggesting that a substantial portion of dementia cases could be influenced by this single genetic factor. While scientists caution that the genetics of Alzheimer’s are complex and…

Alzheimer’s Gene Variant Ties Majority of Dementia Cases
New findings spotlight a single gene variant in Alzheimer’s and dementia risk A landmark study published in npj Dementia suggests that a single gene variant and the protein it encodes may play a pivotal role in a substantial portion of Alzheimer’s disease and related dementias. While dementia is a complex condition with multiple contributing factors,…
