Kiss-Shrink-Run: A Hybrid Mechanism Unveiled for Neuronal Release
Cracking the Code of Neurotransmission The brain’s ability to communicate with astonishing speed hinges on how synaptic vesicles release their chemical messages. For decades, scientists debated whether vesicles briefly touched the presynaptic membrane in a “kiss-and-run” fashion or fully merged in an irreversible “full collapse.” A groundbreaking study from the University of Science and Technology…

Rab Proteins and Memory: Rab4/Rab10 in Synaptic Potentiation
Understanding the cellular logistics of memory formation Memory formation hinges on synaptic potentiation, a process where active neural connections strengthen by structural changes that expand their network of communication. This intricate remodeling requires a precisely timed and localized delivery of cellular components to the growing synapse. In this context, a large family of cellular switches…

Against All Odds: How Doug Whitney Defies Early-Onset Alzheimer’s
Against All Odds: A man who defies a genetic destiny Doug Whitney, a 76-year-old Seattle retiree, carries a rare genetic mutation long thought to guarantee early-onset Alzheimer’s. Yet, decades after the predicted onset, his cognitive health remains robust. He is a living anomaly in a family history that otherwise reads like a cautionary tale, and…

EPG5 gene errors link infant syndrome to Parkinson’s disease
EPG5 gene errors connect infant neurodevelopmental disorder to adult neurodegeneration A surprising thread is emerging from recent research: errors in the EPG5 gene, already known to cause the severe infant condition Vici syndrome, may also contribute to the development of Parkinson’s disease and related dementias in adolescence and adulthood. The large, international study, published in…
