The Maryland Center for Multiple Sclerosis
Physicians and Staff
Horea Rus, M.D.
Dr. Rus is an Associate Professor with the Department of Neurology at the University of Maryland Medical School. He sees patients one day a
week as well as runs a research laboratory. Dr. Rus is funded by the National Institute of Health, Veterans Administration and the National
Multiple Sclerosis Society.
Dr. Rus’s specific laboratory research lies in understanding the mechanisms of oligodendrocyte cell death through a process called apoptosis.
Oligodendorcytes are special cells in the brain that make myelin. Myelin is wrapped around nerve fibers and helps increase the speed of nerve
transmission. It is felt that injury or death of oligodendrocytes contributes to the MS disease process. In MS there are periods of time when the
disease is most active. The hallmark of active MS is inflammation. During the active, inflammatory phase of multiple sclerosis, oligodendrocytes
undergo apoptosis (or cell death). There are less oligodendrocytes therefore less ability to make myelin. This can contribute to the demyelinating
process and the accumulation of disability.
In Dr. Rus’s lab, he and his colleagues have shown that proteins once thought to only contribute to the destructive process in MS also may
contribute to the prevention of oligodendrocyte death. Dr. Rus and his colleagues recently discovered a new protein (RGC-32) involved in activation
of cell cycle in oligodendrocytes. They are now searching for ways to find if targeting of this protein might represent a potential treatment for MS.

Dr. Rus sees patients in the Neurology Ambulatory Center on Monday afternoons. To make an appointment please call 410-328-4323.
