Pionniers dans le diagnostic précoce et fiable de la maladie d'Alzheimer
Dans le cadre du dépistage d’Alzheimer, les biomarqueurs du liquide céphalorachidien (LCR), développés pour la première fois par Fujirebio il y a plus de 25 ans, ont évolué au fil du temps. Ils sont passés de biomarqueurs de recherche à des outils de diagnostic spécialisés. L'utilisation manuelle par les premiers utilisateurs dispose aujourd’hui d'une mise en œuvre généralisée dans la mise en place de tests de routine entièrement automatisés.
Le diagnostic précoce d'Alzheimer à l'aide d’échantillons de biomarqueurs LCR permet de détecter quatre protéines : deux formes de protéines amyloïdes (Aβ1-42 et Aβ1-40) et deux formes de protéines Tau (Total Tau et phospho-Tau). Si un patient est atteint de la maladie d'Alzheimer, alors ces protéines seront présentes à des taux anormalement bas (rapport Aβ1-42 et Aβ1-42/Aβ1-40) et élevés (Tau total et phospho-Tau). Les taux d'Aβ1-42 et le rapport Aβ1-42/Aβ1-40 peuvent être faibles bien avant que les symptômes de la maladie d'Alzheimer ne commencent à se manifester.
De nos jours, la communauté scientifique fonde de grands espoirs sur l'utilisation des tests sanguins comme outil encore plus simple, et potentiellement plus répandu, du dépistage de la maladie d'Alzheimer. Des biomarqueurs à base de plasma pour les deux protéines amyloïdes (Aβ1-42 et Aβ1-40) et pour la protéine phospho-Tau sont déjà disponibles auprès de Fujirebio dans le cadre de tests entièrement automatisés (à des fins de recherche uniquement). La recherche se poursuit au sein du Fujirebio Neuro Center of Excellence, et a conduit, par exemple, à la publication de nouveaux tests pour deux biomarqueurs de diagnostic précoce d’Alzheimer prometteurs : NPTX2 et sTREM2, tous deux à usage de recherche uniquement.
Cette page rassemble des ressources et des informations sur la manière dont Fujirebio contribue et collabore étroitement avec la communauté scientifique internationale et les organisations partenaires afin de développer les outils de diagnostic de la neurodégénérescence du futur.
L'histoire de Daniel et Sophia sur la vie avec la maladie d'Alzheimer
Dans cette vidéo, nous suivons Daniel et Sophia de Suède. Daniel a reçu un diagnostic de maladie d'Alzheimer alors qu'il entrait tout juste dans la cinquantaine. Sa femme et lui-même partagent leur histoire depuis les premières suspicions, le diagnostic précoce et comment eux et leur famille vivent avec la maladie. Et leur espoir pour l'avenir.
