Recent studies utilizing novel technologies in samples from MS patients, and in an animal model of MS, experimental autoimmune encephalomyelitis (EAE), exposed the detrimental and the beneficial, in part contradictory, functions of this heterogeneous cell population. In this review, we summarize the various roles of astrocytes in recruiting immune cells to lesion sites, engendering the inflammatory loop, and inflicting tissue damage. The roles of astrocytes in suppressing excessive inflammation and promoting neuroprotection and repair processes is also discussed. The pivotal roles played by astrocytes make them an attractive therapeutic target. Improved understanding of astrocyte function and diversity, and the mechanisms by which they are regulated may lead to the development of novel approaches to selectively block astrocytic detrimental responses and\/or enhance their protective properties.<\/jats:p>","DOI":"10.3390\/ijms22115904","type":"journal-article","created":{"date-parts":[[2021,5,31]],"date-time":"2021-05-31T05:53:38Z","timestamp":1622440418000},"page":"5904","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":75,"title":["Astrocytes in Multiple Sclerosis\u2014Essential Constituents with Diverse Multifaceted Functions"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7649-5693","authenticated-orcid":false,"given":"Rina","family":"Aharoni","sequence":"first","affiliation":[{"name":"Department of Immunology, The Weizmann Institute of Science, Rehovot 761001, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raya","family":"Eilam","sequence":"additional","affiliation":[{"name":"Department of Immunology, The Weizmann Institute of Science, Rehovot 761001, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth","family":"Arnon","sequence":"additional","affiliation":[{"name":"Department of Immunology, The Weizmann Institute of Science, Rehovot 761001, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"169","DOI":"10.1056\/NEJMra1401483","article-title":"Multiple sclerosis","volume":"378","author":"Reich","year":"2018","journal-title":"N.
