CLN5 disease, late infantile variant phenotype neuronal ceroid lipofuscinosis, is a severe neurodegenerative disease caused by mutations in the CLN5 gene, which encodes a lysosomal protein of unknown function. Cln5-deficiency in mice leads to loss of thalamocortical neurons, and glial activation, but the underlying mechanisms are poorly understood. We have now studied the gene expression of Cln5 in the mouse brain and show that it increases gradually with age and differs between neurons and glia, with the highest expression in microglia. In Cln5(-/-) mice, we documented early and significant microglial activation that was already evident at 3 months of age. Loss of Cln5 also leads to defective myelination in vitro and in the developing mouse brain. This was accompanied by early alterations in serum lipid profiles, dysfunctional cellular metabolism and lipid transport in Cln5(-/-) mice. Taken together, these data provide significant new information about events associated with Cln5-deficiency, revealing altered myelination and disturbances in lipid metabolism, together with an early neuroimmune response.

View all literature mentionsIt serves as a gateway for clinicians, families and researchers who have an interest in or are affected by Batten disease or who wish to find out more. Information can be accessed via four main routes - Clinicians, Families, Researchers, Professional Support. The Clinical route describes Batten disease and includes details on diagnosis and diagnostic services. The Family route also describes Batten disease and lists support groups. The Research route includes the NCL Mutation Database, established in 1998, and other useful information. The Professional Support route includes details of coordinated initiatives to support those affected by Batten disease. A fifth route, Research Consortia, serves to meet research needs and currently act as a focus for collaborative efforts to identify the remaining human and animal NCL genes and facilitate functional approaches. An additional route, Creativity, has been launched to display creative items from families with Batten disease, and to celebrate life, in both its fullness and fragility.
