'Mini-brains' model myelin damage and regeneration, offering new tool for MS drug testing

Researchers have developed innovative 3D 'mini-brains' to accelerate the search for drug treatments for multiple sclerosis (MS), an autoimmune condition affecting nearly 3 million people worldwide. These laboratory-grown brain models can replicate myelin damage and regeneration processes, providing scientists with a more accurate platform for testing potential therapies. The breakthrough, published in Nature Neuroscience, addresses a critical need for better MS treatments. This advancement could significantly reduce development time and costs for new medications, potentially improving outcomes for MS patients who currently have limited therapeutic options for halting disease progression.
