TDP43 Seeding Mouse Models

Recapitulate the key structural features and spreading of TDP-43 proteinopathy found in the brain of ALS patients using TDP-43 Seeding Mouse Models

Home » Neurology Research Models and Services  » ALS models and services » ALS models – TDP-43 Seeding Mouse Models

TDP-43 seeding mouse models are established by injecting brain extracts from patients affected by TDP-43 proteinopathy. TAR DNA binding protein (TDP-43) encoded by TARDBP gene, is a major protein involved in the pathogenesis of Amyothropic lateral sclerosis (ALS) and  frontotemporal dementia (FTD). Therefore, injection of brain extracts from these diseases in the brain of mice closely mimics the structural features of TDP-43 aggregates found in patients, and allows studying the pathologic spreading of TDP-43 in response to novel compounds as a therapeutic readout.  

As part of our specialised preclinical research services, InnoSer offers research services including efficacy studies in TDP-43 seeding mouse models, using either recombinant and/or patient-derived seeds. Accordingly, brain extracts from both ALS and FTD patients can be used, mimicking the unique disease pathophysiology, with the choice of the brain source extracts ultimately depending on your target disease of interest. 

Take advantage of InnoSer’s preclinical contract research expertise in modelling TDP-43 pathology, flexibility, and collaborative approach for your research. Our in-house neurology experts have long-standing experience working with seeding-based ALS, but also other neurodegenerative disease models. We are happy to help guide your decision on study design fit for your current research goals. 

As part of InnoSer’s neurology ALS mouse model portfolio, we also offer efficacy studies in mouse models with TDP-43 pathology, including transgenic TDP-43 mouse models, as well as a SOD1-G93A transgenic ALS mouse model. However, as each model is unique, modelling distinct pathophysiological aspects of ALS, we recommend you discuss the most appropriate model with our neurology study directors. 

TDP43 Seeding Mouse Model key model characteristics:

  • Recombinant and patient-derived TDP-43 brain extract seeds are available.
  • TDP-43 aggregates can be injected in both wild-type (WT) or transgenic mice.
