日本の研究チームは、幹細胞から神経細胞への分化を促す効果が天然のビタミンKの3倍に達する新たなビタミンK化合物を開発した。2025年に発表されたこの研究は、アルツハイマー病やパーキンソン病のように脳細胞が破壊される疾患の治療を目指している。
芝浦工業大学の廣田義久准教授と須原義智教授が率いる研究チームは、ビタミンKとビタミンAの構成要素を組み合わせ、12種類のハイブリッド分子を生成した。そのうち「Novel VK」と名付けられた化合物は、マウスの神経前駆細胞を用いた実験において、神経細胞の成長を強力に促進する特性が認められた。

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.
