In 2006, the promyelocytic leukemia protein was described as the first RF against human cytomegalovirus (HCMV) infection which is antagonized by the viral immediate early protein IE1. Since then, at least 15 additional RFs against HCMV have been identified, including the chromatin regulatory protein SPOC1, the cytidine deaminase APOBEC3A and the dNTP triphosphohydrolase SAMHD1. These RFs affect distinct steps of the viral replication cycle such as viral entry, gene expression, the synthesis of progeny DNA or egress. This review summarizes our current knowledge on intrinsic immune mechanisms restricting HCMV replication as well as on the viral strategies to counteract the inhibitory effects of RFs. Detailed knowledge on the interplay between host RFs and antagonizing viral factors will be fundamental to develop new approaches to combat HCMV infection.<\/jats:p>","DOI":"10.3390\/v13020179","type":"journal-article","created":{"date-parts":[[2021,1,26]],"date-time":"2021-01-26T08:29:16Z","timestamp":1611649756000},"page":"179","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Intrinsic Immune Mechanisms Restricting Human Cytomegalovirus Replication"],"prefix":"10.3390","volume":"13","author":[{"given":"Eva-Maria","family":"Schilling","sequence":"first","affiliation":[{"name":"Institute of Virology, Ulm University, 89081 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myriam","family":"Scherer","sequence":"additional","affiliation":[{"name":"Institute of Virology, Ulm University, 89081 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9878-3119","authenticated-orcid":false,"given":"Thomas","family":"Stamminger","sequence":"additional","affiliation":[{"name":"Institute of Virology, Ulm University, 89081 Ulm, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1109","DOI":"10.1038\/ni1125","article-title":"Intrinsic immunity: A front-line defense against viral attack","volume":"5","author":"Bieniasz","year":"2004","journal-title":"Nat.
