Japanska forskare utvecklar förbättrat vitamin K för neuronregenerering

Forskare i Japan har skapat nya vitamin K-föreningar som är tre gånger mer effektiva än naturliga former när det gäller att omvandla stamceller till neuroner. Arbetet, som publicerades 2025, fokuserar på sjukdomar som förstör hjärnceller, såsom Alzheimers och Parkinsons.

Biträdande professor Yoshihisa Hirota och professor Yoshitomo Suhara ledde teamet vid Shibaura Institute of Technology. De kombinerade vitamin K med element från vitamin A för att framställa 12 hybridmolekyler. En förening, kallad Novel VK, utmärkte sig i tester på neurala stamceller från möss genom sin starka förmåga att främja neuronalt tillväxt.

Researchers at McGill University report a drug-based method to temporarily enhance natural killer (NK) cells—an immune cell type—by inhibiting two proteins, improving the cells’ ability to attack several aggressive cancers in preclinical experiments.

Researchers at the University of Cambridge have developed miniature lab-grown models of the human brain and spinal cord that show damaged nerve fibers can regain the ability to regrow under certain conditions.

A widely studied anti-aging treatment triggered significant brain damage in mice, according to new research from the University of Connecticut. The drug combination dasatinib plus quercetin caused myelin loss and changes resembling those seen in multiple sclerosis. The findings raise questions about its use in longevity studies and off-label therapies.

Researchers at the University of Hong Kong have developed a world-first nasal spray that delivers neurotherapeutic powder directly to the brain as first aid for ischemic stroke patients. The treatment, named NanoPowder, is designed to reduce brain damage by more than 80 per cent and improve stroke survival rates. Clinical trials are expected by 2030.

Northwestern University researchers report they have printed flexible “artificial neurons” that generate realistic electrical spike patterns and can trigger responses in living mouse brain tissue. The team says the work, published April 15 in Nature Nanotechnology, could help advance brain-machine interfaces and more energy-efficient, brain-inspired computing.
