Multiple sclerosis (MS) is an autoimmune disease characterised by lymphocytic
infiltration of the central nervous system and subsequent destruction of myelin and axons.
On the background of a genetic predisposition to autoimmunity, environmental triggers are
assumed to initiate the disease. The majority of MS research has focused on the
pathological involvement of lymphocytes and other immune cells, yet a paucity of attention
has been given to erythrocytes, which may play an important role in MS pathology. The
following review briefly summarises how erythrocytes may contribute to MS pathology
through impaired antioxidant capacity and altered haemorheological features. The effect of
disease-modifying therapies on erythrocytes is also reviewed. It may be important to
further investigate erythrocytes in MS, as this could broaden the understanding of the
pathological mechanisms of the disease, as well as potentially lead to the discovery of
novel and innovative targets for future therapies.
