Zusammenfassung
Hintergrund
Die amyotrophe Lateralsklerose (ALS) und die frontotemporale Demenz (FTD) teilen gemeinsame neuropathologische und – im Falle einer vorliegenden Genmutation – auch genetische Ursachen. In der Literatur werden derzeit, neben weiteren selteneren Varianten, 5 ALS-FTD-Gene beschrieben.
Ziel der Arbeit
Der aktuelle Forschungsstand zu Therapiemöglichkeiten der ALS und FTD soll dargestellt sowie ein Ausblick auf mögliche Gentherapien für ALS-FTD gegeben werden.
Material und Methoden
Analyse des Zeitverlaufs der ALS- und FTD-Forschung unter Berücksichtigung des steigenden Kenntnisstands der den Erkrankungen zugrunde liegenden Pathomechanismen.
Ergebnisse
Neben antiinflammatorischen Ansätzen oder der Stabilisierung von Proteinfaltungen werden aktuell vielversprechende genspezifische Therapieansätze entwickelt, welche auf gemeinsame Ursachen von ALS und FTD gerichtet sind und somit auch auf beide Erkrankungen wirken sollen.
Diskussion
Bisher gibt es keine kausalen Therapiemöglichkeiten für ALS und FTD. Die steigende Bedeutung genetischer Ursachen lenkt den Fokus auf die Entwicklung genspezifischer Therapien.
Abstract
Background
Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) share common neuropathological features and in the case of a gene mutation, also a genetic cause. To date five ALS-FTD genes are described in the literature in addition to other rare variants.
Objective
The current state of research on treatment options for ALS and FTD is presented and an outlook on possible gene-specific approaches for ALS-FTD is provided.
Material and methods
Analysis of the progression of ALS and FTD research by considering the increasing state of knowledge on the underlying pathomechanisms of the diseases.
Results
In addition to anti-inflammatory approaches and stabilization of protein folding, promising gene-specific treatment approaches are currently being developed, which target common causes of ALS and FTD and therefore have an effect on both diseases.
Conclusion
So far there are no causal treatment options for ALS and FTD. The increasing importance of genetic causes directs the focus to the development of gene-specific treatment.
