This report summarizes our studies and others concerning cerebellar abnormalities in rolling mice based on chemical neuroanatomy. While there are no obvious cerebellar deformations in this mutant mouse, the altered functions of Purkinje cells can be revealed as a reduced expression of type 1 ryanodine receptor (RyR1) in all Purkinje cells uniformly throughout the cerebellum, and as an ectopic expression of tyrosine hydroxylase (TH) in the Purkinje cell subsets with the zebrin II\u2014immunopositive phenotype. As the mutated Ca<jats:sub>\u02c5<\/jats:sub>2.1 channel is expressed at uniform levels in all Purkinje cells, its copresence with RyR1 staining suggests that a Ca<jats:sub>\u02c5<\/jats:sub>2.1 channel dysfunction links with the expression of RyR1 in Purkinje cells of rolling mice. However, an ectopic expression of TH in the Purkinje cells is topologically related to the projection of corticotrophin-releasing factor\u2014immunopositive climbing fibers rather than expression of the mutated Ca<jats:sub>\u02c5<\/jats:sub>2.1 channel. On the other hand, increased levels of serotonin (5-HT) in 5-HTergic fibers were revealed immunohistochemically in Purkinje cells of the vermis of rolling cerebellum. Thus, to determine whether or not cerebellar abnormalities are related to Purkinje cell populations revealed by zebrin II expression is essential for enhancing our understanding of the pathogenesis of hereditary cerebellar ataxic mutants such as rolling mice.<\/jats:p>","DOI":"10.1100\/tsw.2010.205","type":"journal-article","created":{"date-parts":[[2011,8,15]],"date-time":"2011-08-15T05:32:08Z","timestamp":1313386328000},"page":"2032-2038","source":"Crossref","is-referenced-by-count":6,"title":["Zebrin II Expressing Purkinje Cell Phenotype\u2014Related and\u2014Unrelated Cerebellar Abnormalities in Ca<sub>\u02c5<\/sub>2.1 Mutant, Rolling Mouse Nagoya"],"prefix":"10.1100","volume":"10","author":[{"given":"Kazuhiko","family":"Sawada","sequence":"first","affiliation":[{"name":"Laboratory of Anatomy, Department of Physical Therapy, Faculty of Medical and Health Sciences, Tsukuba International University, Tsuchiura, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihiro","family":"Fukui","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Developmental Neurobiology, University of Tokushima Graduate School, Institute of Health Biosciences, Tokushima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"98","container-title":["The Scientific World JOURNAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2010\/784363.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2010\/784363.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,23]],"date-time":"2016-08-23T11:25:41Z","timestamp":1471951541000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/tswj\/2010\/784363\/abs\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":0,"alternative-id":["784363"],"URL":"https:\/\/doi.org\/10.1100\/tsw.2010.205","relation":{},"ISSN":["1537-744X"],"issn-type":[{"value":"1537-744X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010]]}}}
