Background: Experimental autoimmune encephalomyelitis (EAE) is the most widely used animal model for multiple sclerosis (MS). It is a rapid model, commonly induced in rodents. Even if EAE does not replicate all MS characteristics, it is appropriate to investigate the development of the disease, including the immune and neuroinflammatory aspects.

Despite this, health status commonly worsens in the last years of life. Frailty is an intermediate and reversible state that often precedes dependency and therefore, its identification may be essential to prevent dependency.

However, many aspects of immunosenescence are not completely understood, as the characteristics of the immune cells of nonagenarians and centenarians or the features and implications of extracellular vesicles (EVs). In this study, we analyzed blood samples from 51 individuals aged 20-49 and 70-104 years.

They carry proteins, lipids, and nucleotides such as microRNAs (miRNAs) from the secreting cell that can modulate target cells. We and others have previously described the presence of EVs in peripheral blood of multiple sclerosis (MS) patients and postulated them as novel biomarkers.

Nevertheless, with disease progression, remyelination tends to fail, increasing the characteristic neurodegeneration of the disease. It is essential to understand the mechanisms that operate in the processes of myelination, demyelination and remyelination to develop treatments that promote the production of new myelin, thereby protecting the central nervous system.
