Abstract
In primary glial cells, cystB is found in progenitor and differentiated oligodendrocytes as well as in astrocytes. In the cerebellum, only oligodendrocyte progenitors express cystB. In myelin-producing cells, cystB synthesis is strongly down-regulated and the protein is not detectable. Astrocytes and Bergmann glia express cystB at all the developmental stages analyzed both in the cell body and in the fibers. Most neurons of developing and adult rat cerebellum do not express detectable amounts of cystB, with the exception of the Purkinje cells and of some cells of the differentiated molecular layer. In human cerebellum, cystB is present in Purkinje cells and Bergmann glial fibers only. cystB is also found in the cortical neurons of the dentate gyrus of the hippocampus. In rat cerebellum, cystB forms a complex with a number of proteins, two of which are specific to the nervous system. The cellular co-localization of cystB and its partners in developing and adult cerebellum is also shown.
