«We found that
fibrinogen stops adult stem cells from transforming into the mature cells that produce myelin,» explained first author of the study Mark Petersen, MD, a visiting scientist in Akassoglou's laboratory and an assistant adjunct professor of pediatrics at UCSF.
They found that when
fibrinogen (a blood - clotting protein) leaks into the central nervous system, it
stops brain cells from producing myelin and, as a result, prevents repair.
Her aim is to understand, at the molecular level, the mechanisms that control communication between the brain, immune system, and blood vessels — with the ultimate goal of designing new therapies that slow,
stop, or reverse the progression of a wide range of neurological disorders, such as MS. Recently, Dr. Akassoglou's lab identified how microglia — a type of immune cell that acts as the brain's first line of defense — are activated when
fibrinogen enters the brain or spinal cord.
