Desequilibrio en la excitaci\u00f3n del circuito neuronal<\/h3>\n
La mutaci\u00f3n estudiada afecta al receptor de adenosina tipo 1. Este receptor ejerce un efecto inhibidor sobre su hom\u00f3logo, el receptor de adenosina tipo 2, que facilita la liberaci\u00f3n de glutamato, y la excitabilidad del circuito. Por tanto, seg\u00fan los resultados publicados, la mutaci\u00f3n impedir\u00eda la interacci\u00f3n molecular y funcional de ambos receptores de adenosina, y en consecuencia, facilitar\u00eda la liberaci\u00f3n de glutamato, que provocar\u00eda una hiperexcitabilidad en los circuitos neuronales del estriado.<\/p>\n
Los receptores de adenosina, son receptores cerebrales ensamblados a prote\u00ednas G e involucrados en funciones motoras. Previamente, ya se hab\u00eda apuntado su implicaci\u00f3n en enfermedades neurodegenerativas como Parkinson.<\/p>\n
En este estudio tambi\u00e9n han participado investigadores e investigadoras de la Universidad Aut\u00f3noma de Barcelona, \u200b\u200bdel Luxembourg Institute of Health (LIH), y del National Institutes of Health de Baltimore.<\/p>\n

El Instituto de Investigaci\u00f3n Biom\u00e9dica de Bellvitge (IDIBELL) es un centro de investigaci\u00f3n en biomedicina creado en 2004. Est\u00e1 participado por el Hospital Universitario de Bellvitge y el Hospital de Viladecans del Instituto Catal\u00e1n de la Salud, el Instituto Catal\u00e1n de Oncolog\u00eda, la Universidad de Barcelona y el Ayuntamiento de L’Hospitalet de Llobregat.<\/em><\/p>\nEl IDIBELL es miembro del Campus de Excelencia Internacional de la Universidad de Barcelona HUBc y forma parte de la instituci\u00f3n CERCA de la Generalitat de Catalunya. En 2009 se convirti\u00f3 en uno de los cinco primeros centros de investigaci\u00f3n espa\u00f1oles acreditados como instituto de investigaci\u00f3n sanitaria por el Instituto de Salud Carlos III. Adem\u00e1s, forma parte del programa “HR Excellence in Research” de la Uni\u00f3n Europea y es miembro de EATRIS y REGIC. Desde el a\u00f1o 2018, IDIBELL es un Centro Acreditado de la Fundaci\u00f3n Cient\u00edfica AECC (FCAECC).<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"Un equipo del IDIBELL, la UB y el Instituto de Neurociencias (UBNeuro) observa que la falta de interacci\u00f3n entre dos receptores de adenosina neuronales podr\u00eda ser la responsable de la alteraci\u00f3n de los circuitos cerebrales en la enfermedad de Parkinson temprana o juvenil.<\/p>\n","protected":false},"author":8,"featured_media":21584,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[320,196,277],"tags":[],"class_list":["post-21583","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-area-neurociencias","category-neurofarmacologia-y-dolor","category-programa-de-neurociencias"],"publishpress_future_action":{"enabled":false,"date":"2025-04-10 23:32:27","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category"},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts\/21583","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/comments?post=21583"}],"version-history":[{"count":1,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts\/21583\/revisions"}],"predecessor-version":[{"id":21585,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts\/21583\/revisions\/21585"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/media\/21584"}],"wp:attachment":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/media?parent=21583"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/categories?post=21583"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/tags?post=21583"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
