Studying Specific Cells That May Prevent Neurodegeneration in MS Patients

Oligodendrocytes are the cells in the central nervous system that wrap neurons with myelin sheaths and allow for rapid conduction of action potentials. A largely unexplained role of oligodendrocyte progenitors is how they interface and interact with immune cells and how these interactions influence the immune response and oligodendrocyte function and survival. Dr. Harrington's project proposes to define the molecular mechanisms that enable interactions between oligodendrocyte progenitors and cytotoxic T lymphocytes.

Project Description

What We Know:
Oligodendrocytes are the cells in the central nervous system that wrap neurons with myelin sheaths and allow for rapid conduction of action potentials. Oligodendrocytes have many roles other than wrapping axons including communicating with neurons through synapses. A largely unexplained role of oligodendrocyte progenitors is how they interface and interact with immune cells and how these interactions influence the immune response and oligodendrocyte function and survival.

Our Plan to Help:
This grant proposes to define the molecular mechanisms that enable interactions between oligodendrocyte progenitors and cytotoxic T lymphocytes. Dr. Harrington's team believes that oligodendrocyte progenitors through interactions with immune cells, can be co-opted into expressing myelin antigens and target themselves for killing by cytotoxic T lymphocytes and that their death leads to impaired remyelination.

The Potential Impact:
The results of this research may provide information about the mechanisms that contribute to oligodendrocyte progenitor cell death and neurodegeneration and provide insight into the biology of progressive multiple sclerosis. Dr. Harrington hopes that results from this study will help guide the development of therapies for multiple sclerosis that promote oligodendrocyte progenitor survival and prevent neurodegeneration.

How You Can Help:

By donating to Dr. Harrington's research, you are directly contributing to potential new therapies for MS that my prevent neurodegeneration.
