The precise coordination of different cellular processes<br \/>\nsuch as cytoskeleton dynamics, membrane trafficking and cell adhesion during<br \/>\nmigration is achieved by a variety of signaling pathways. GTPases play a central role in<br \/>\nall these processes. The small GTPase Rab21 regulates migration and neurite growth in<br \/>\ndeveloping neurons. Moreover, regulators and effectors of Rab21 have been implicated<br \/>\nin brain pathologies with cortical malformations, suggesting a key function for the<br \/>\nRab21 signaling pathway in cortical development. Mechanistically, it has been posited<br \/>\nthat Rab21 influences cell migration by controlling the trafficking of endocytic vesicles<br \/>\ncontaining adhesion molecules. However, direct evidence of the participation of Rab21<br \/>\nor its mechanism of action in the regulation of cortical migration is still incomplete. In<br \/>\nthis study, we demonstrate that Rab21 plays a critical role in the differentiation and<br \/>\nmigration of pyramidal neurons by regulating the levels of the amyloid precursor<br \/>\nprotein on the neuronal cell surface. Rab21 loss of function increased the levels of<br \/>\nmembrane-exposed APP, resulting in impaired cortical neuronal differentiation and<br \/>\nmigration.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author: Peralta Cuasolo Yael Macarena | email: macafcq@gmail.com | Cellular and Molecular Neurobiology<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[34],"tags":[18],"class_list":["post-1898","post","type-post","status-publish","format-standard","hentry","category-session-2","tag-cellular-and-molecular-neurobiology"],"_links":{"self":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1898","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/comments?post=1898"}],"version-history":[{"count":3,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1898\/revisions"}],"predecessor-version":[{"id":2271,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1898\/revisions\/2271"}],"wp:attachment":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/media?parent=1898"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/categories?post=1898"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/tags?post=1898"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
