Ilmuwan Jepang kembangkan vitamin K yang ditingkatkan untuk regenerasi neuron

Para peneliti di Jepang telah menciptakan senyawa vitamin K baru yang tiga kali lebih efektif daripada bentuk alaminya dalam mengubah sel punca menjadi neuron. Penelitian yang diterbitkan pada tahun 2025 ini menyasar penyakit yang merusak sel otak seperti Alzheimer dan Parkinson.

Lektor Kepala Yoshihisa Hirota dan Profesor Yoshitomo Suhara memimpin tim tersebut di Shibaura Institute of Technology. Mereka menggabungkan vitamin K dengan elemen vitamin A untuk menghasilkan 12 molekul hibrida. Salah satu senyawa, yang disebut Novel VK, menonjol dalam pengujian pada sel progenitor saraf tikus karena kemampuannya yang kuat dalam mendukung pertumbuhan neuron.

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.
