Blood Proteins Reveal MS Immune System Attack Starts Years Before Symptoms

Scientists detect hidden brain damage years before MS symptoms

Scientists at UCSF have uncovered evidence that multiple sclerosis silently damages the brain years before diagnosis. By studying proteins in blood samples, they identified early immune signals and markers of nerve damage. The findings point to IL-3 and MOG as crucial early indicators — and open the door to new diagnostic blood tests and preventive strategies.

Blood proteins reveal MS immune system attack starts years before symptoms

By the time patients start seeking care for multiple sclerosis (MS), the disease has already been damaging their brains for years. But until recently, scientists didn't understand which brain cells were being targeted or when the injury began.

How Multiple Sclerosis Damages a Brain Long Before Symptoms Appear

By the time patients start seeking care for multiple sclerosis (MS), the disease has already been damaging their brain for years. But until recently, scientists didn’t understand which brain cells were being targeted or when the injury began. Now, by analyzing thousands of proteins found in the blood, scientists at the University of California, San Francisco (UCSF), have created what they view as the clearest picture yet of when the disease atta…
