Ancient Viruses Shaped Our Brains

Ancient viruses played a pivotal role in the development of myelin, crucial for complex vertebrate brains. The discovery of "RetroMyelin," a retrovirus-derived element essential for myelin production across mammals, amphibians, and fish, underscores the impact of viral genes on vertebrate evolution.

Redefining Myelin Damage

A new study explores the intricate relationship between myelin degeneration and neuron health. Contrary to the traditional view that demyelination primarily leads to axon degeneration, the study found that axons enwrapped in defective myelin are at a higher risk.

Pregnancy Hormone Estriol May Reverse Myelin Damage in Multiple Sclerosis

Treating a mouse model of multiple sclerosis (MS) with the pregnancy hormone estriol could reverse myelin breakdown in the brain's cortex, a primary area affected in MS. MS results in inflammation that damages the myelin coating around nerve fibers in the brain's cortex, leading to disability worsening.

Antihistamine Sparks Hope for Myelin Repair in Multiple Sclerosis

A new study paves the way for potential treatments for Multiple Sclerosis (MS) by identifying the OTC antihistamine, clemastine, as an effective drug for brain repair. Utilizing a newly-developed MRI scan technique, scientists were able to observe and measure the impact of clemastine on brain myelin levels.

Aging Myelin: A New Perspective in Alzheimer’s Disease Progression

Age-related degeneration of myelin, the insulating layer around nerve cells in the brain, actively promotes disease-related changes in Alzheimer's. Researchers examined mouse models of Alzheimer's with myelin defects, finding that these defects accelerated the formation of amyloid plaques, a characteristic sign of Alzheimer's.
