Many human neurological, neuromuscular and musculoskeletal diseases involve deficits in motor function. Currently, investigations into disease onset and progression in mouse models of these conditions depend on somewhat unreliable tests that only measure a few motor functions. Now, Mandillo et al. validate an automated home-cage wheel-running system for the measurement of early motor deficits in mouse disease models. By undertaking studies at two centres, the researchers show that the system consistently detects differences in performance among four inbred strains of mice. They also report that the system allows the detection of very early motor function deficits in mutant mouse models of two progressive neurodegenerative diseases and in a mouse strain with subtle gait abnormalities. This new test therefore provides a reliable method for detecting motor deficits at pre-symptomatic stages in mouse disease models that should be useful in longitudinal investigations of potential therapeutic agents.

DMM Journal Meeting 2024: Pre-clinical Modelling of Human Genetic Disease and Therapy

Registration is now open for our 2024 Journal Meeting. Rapid advances in gene editing and genetic technologies have revolutionised our ability to model human genetic disease and provided new hope for gene therapies. At this Meeting, we will present the very latest advances in modelling human genetic disease.
A new call for papers is underway

The Forest of Biologists

The Forest of Biologists is a biodiversity initiative created by The Company of Biologists, with support from the Woodland Trust. For every Research and Review article published in Disease Models & Mechanisms a native tree is planted in a UK forest. In addition to this we are protecting and restoring ancient woodland and are dedicating these trees to our peer reviewers. Visit our virtual forest to learn more.
