Relative telomere length (TL) is regarded as a biomarker of biological age. Accelerated immune aging, as represented by TL reduction, has been demonstrated in autoimmune diseases, including multiple sclerosis (MS). However, it is still unresolved whether telomere shortening is the cause or the consequence of the pathogenic events underlying autoimmunity. Assessing TL in whole blood DNA samples in 138 MS patients and 120 healthy controls showed reduced TL in patients as compared with controls There seems to be a prelude of accelerated telomere shortening, which may increase the risk for development of MS.
