This image shows the region of the brain known as the cerebellum, which is essential for the execution of coordinated movement. The green cells are a specialized form of support cell known as Bergmann glia, which play vital roles in neuronal function and the response to neuronal injury. The image shown is from a mouse with severe neurodegeneration and movement disorder due to mutation in the gene Fig4, which is required for the breakdown of sub-cellular components. A protein that accumulates when this turnover process, known as macroautophagy, is impaired is shown in yellow. Mutation of the Fig4 Gene in humans causes Charcot-Marie-Tooth disease type 4J, a severe neuropathy with movement disorder, weakness and sensory loss.
