The Biology of Multiple Sclerosis

The term ‘Multiple Sclerosis’ refers to the replacement of myelin, a fatty substance that forms a protective sheath around neurones, with scar tissue. It is thought that MS is an auto-immune disorder, where cytotoxic T lymphocytes have essentially attacked molecules in the myelin, although recent studies suggest that both a genetic predisposition and environmental factors are important in determining whether someone develops MS. In this podcast, I will explore the underlying pathology behind the condition, the signs and symptoms sufferers experience, and the current treatments available.
