Myelin Repair Breakthrough : A study by Dr. Hyun Kyoung Lee at Baylor College of Medicine found a way to repair and grow back myelin, the protective coating on nerve impulses. Multiple sclerosis and other myelin-affecting diseases are untreatable, but this discovery offers new treatment possibilities.
The study found that Daam2 protein phosphorylation is crucial for oligodendrocyte development at various stages. Oligodendrocytes make myelin in the brain. The enzyme CK2 phosphorylates. CK2 and Daam2 protect newborns from brain damage from oxygen deprivation during birth. It also fixed myelin damage in older animals’ brains.
Myelin, compared to electrical insulation, is necessary for fast and efficient nerve impulse transmission over long distances. It’s mainly in the brain’s white matter but also body nerves. Demyelinating diseases, like multiple sclerosis, cause the protective sheath to break down, leading to nerve problems.

Damage or loss of the myelin sheath is a sign of untreatable diseases. Multiple sclerosis is well-known, but myelin loss can result from other diseases, such as specific brain injuries.
The team studied the biochemistry and genes of phosphorylated Daam2 mice. “Daam2 phosphorylation impacts oligodendrocyte development stages differently,” Dr. Lee explained. In the early stages, it accelerates precursor cell transformation into glial cells. In later stages, it hampers their development and myelin production.
The find enables more study. Rebuilding lost myelin is a long-standing goal of medical science. Dr. Lee’s final comment highlights new ways to treat myelin damage and potentially alleviate untreatable neurological diseases.
The study’s results are important. New ways to aid those with myelin-degenerating diseases could be discovered by studying myelin restoration.
By studying kinase CK2’s impact on Daam2 phosphorylation, researchers have set the stage for potential drug treatments targeting these specific targets. Scientists hope to confirm early results and develop revolutionary treatments for long-standing diseases.
This study is a significant advancement in neurological research, as demyelinating diseases are common and lack effective treatments.
