Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Review Description
Multiple sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system (CNS), in which astrocytes play an important role as CNS immune cells. However, the activity of astrocytes as antigen-presenting cells (APC) continues to be subject to debate. This review analyses the existing evidence on the participation of astrocytes in CNS inflammation in MS and on several mechanisms that modify astrocyte activity in the disease. Astrocytes play a crucial role in the pathogenesis of MS because they express toll-like receptors (TLR) and major histocompatibility complex (MHC) class I and II. In addition, astrocytes participate in regulating the blood-brain barrier (BBB) and in modulating T cell activity through the production of cytokines. Future studies should focus on the role of astrocytes in order to find new therapeutic targets for the treatment of MS. La esclerosis múltiple (EM) es una enfermedad autoinmune desmielinizante del sistema nervioso central (SNC) en la que los astrocitos tienen una participación importante como células inmunes del SNC, aunque su actividad como células presentadoras de antígeno (APC) aún es discutida. En la presente revisión se analiza la evidencia existente sobre la participación de los astrocitos en la inflamación del SNC en la EM, así como diversos mecanismos que modifican su actividad en la enfermedad. Los astrocitos desempeñan un papel trascendental en la patogénesis de la EM, debido a que expresan receptores TLR, así como proteínas del complejo principal de histocompatibilidad (MHC) clase I y II. Además, participan en la regulación de la barrera hemato-encefálica (BHE) y la modulación de la actividad de los linfocitos T mediante la producción de citocinas. Futuros estudios deberán enfocarse en el papel de los astrocitos con el objetivo de encontrar nuevos blancos terapéuticos para el tratamiento de la EM.
