It is unclear why CCM lesions are primarily confined to brain vasculature, although the 3 CCM-associated genes (\n                      <jats:italic>CCM1<\/jats:italic>\n                      ,\n                      <jats:italic>CCM2<\/jats:italic>\n                      , and\n                      <jats:italic>CCM3<\/jats:italic>\n                      ) are ubiquitously expressed in all tissues.

Ccm3smKO mice developed CCM lesions in the brain with onset at neonatal stages. One-third of Ccm3smKO mice survived upto 6 weeks of age, exhibiting seizures, and severe brain hemorrhage. The early CCM lesions in Ccm3smKO neonates were loosely wrapped by mural cells, and adult Ccm3smKO mice had clustered and enlarged capillary channels (caverns) formed by a single layer of endothelium lacking mural cell coverage. Importantly, CCM lesions throughout the entire brain in Ccm3smKO mice, which more accurately mimicked human disease than the current endothelial cell-specific\n                      <jats:italic>CCM3<\/jats:italic>\n                      deletion models.

Moreover, CCM3-wild type, but not a paxillin-binding defective mutant, rescued the phenotypes in CCM3-deficient pericytes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>\n                      Our data demonstrate for the first time that deletion of a\n                      <jats:italic>CCM<\/jats:italic>\n                      gene in the brain mural cell induces CCM pathogenesis.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1161\/atvbaha.120.314586","type":"journal-article","created":{"date-parts":[[2020,7,9]],"date-time":"2020-07-09T05:00:31Z","timestamp":1594270831000},"page":"2171-2186","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":33,"title":["Mural Cell-Specific Deletion of Cerebral Cavernous Malformation 3 in the Brain Induces Cerebral Cavernous Malformations"],"prefix":"10.1161","volume":"40","author":[{"given":"Kang","family":"Wang","sequence":"first","affiliation":[{"name":"From the Interdepartmental Program in Vascular Biology and Therapeutics, Department of Pathology (K.W., H.Z., Y.H., Q.J., J.S.P., W.M., H.J.Z.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haifeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"From the Interdepartmental Program in Vascular Biology and Therapeutics, Department of Pathology (K.W., H.Z., Y.H., Q.J., J.S.P., W.M., H.J.Z.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"He","sequence":"additional","affiliation":[{"name":"From the Interdepartmental Program in Vascular Biology and Therapeutics, Department of Pathology (K.W., H.Z., Y.H., Q.J., J.S.P., W.M., H.J.Z.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quan","family":"Jiang","sequence":"additional","affiliation":[{"name":"From the Interdepartmental Program in Vascular Biology and Therapeutics, Department of Pathology (K.W., H.Z., Y.H., Q.J., J.S.P., W.M., H.J.Z.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiaki","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Yale Stem Cell Center, Department of Genetics (Y.T., I.-H.P.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In-Hyun","family":"Park","sequence":"additional","affiliation":[{"name":"Yale Stem Cell Center, Department of Genetics (Y.T., I.-H.P.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordan S.","family":"Pober","sequence":"additional","affiliation":[{"name":"From the Interdepartmental Program in Vascular Biology and Therapeutics, Department of Pathology (K.W., H.Z., Y.H., Q.J., J.S.P., W.M., H.J.Z.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2479-6096","authenticated-orcid":true,"given":"Wang","family":"Min","sequence":"additional","affiliation":[{"name":"From the Interdepartmental Program in Vascular Biology and Therapeutics, Department of Pathology (K.W., H.Z., Y.H., Q.J., J.S.P., W.M., H.J.Z.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huanjiao Jenny","family":"Zhou","sequence":"additional","affiliation":[{"name":"From the Interdepartmental Program in Vascular Biology and Therapeutics, Department of Pathology (K.W., H.Z., Y.H., Q.J., J.S.P., W.M., H.J.Z.), Yale University School of Medicine, New Haven, CT."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_4_2_2","first-page":"82","article-title":"[131 cases of cavernous angioma (cavernomas) of the CNS, discovered by retrospective analysis of 24,535 autopsies].","volume":"35","author":"Otten P","year":"1989","unstructured":"Otten, P, Pizzolato, GP, Rilliet, B, Berney, J.
