Progressive degeneration of the ependymal cell liberates trypomastigotes back into the perivascular space, from which re-entry into the blood may occur. Re-entry to the blood does not take place from any tissues other than the brain and its membranes. These findings suggest that the ependymal cells of the choroid plexus are the site of the cryptic stage of the sleeping-sickness trypanosome.<\/jats:p>","DOI":"10.1136\/bmj.285.6352.1380","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T11:00:59Z","timestamp":1238670059000},"page":"1380-1382","source":"Crossref","is-referenced-by-count":25,"title":["Cryptic stage of sleeping-sickness trypanosome developing in choroid plexus epithelial cells."],"prefix":"10.1136","volume":"285","author":[{"given":"M O","family":"Abolarin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D A","family":"Evans","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D G","family":"Tovey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W E","family":"Ormerod","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1982,11,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"736","DOI":"10.1016\/0035-9203(71)90088-5","article-title":"An amastigote phase of the sleeping sickness trypanosome","volume":"65","author":"Ormerod, W.E.; Venkatesan, S.","year":"1971","unstructured":"Ormerod WE, Venkatesan S.
