title: Distribution and developmental expression of lamin-like immunoreactivity in the central nervous system.
abstract: Lamins are the major proteic constituents of the nuclear lamina, the innermost layer of the nuclear membrane. The immunolocalization of lamins in the rat central nervous system was studied using polyclonal antibodies. Besides an ubiquitarious localization in the nuclear membranes of neurons and glial cells, an intense lamin-like immunoreactivity was found in the soma and dendrites of cerebellar Purkinje cells. The same specific reaction was also observed in the human cerebellum. Experiments performed in newborn animals demonstrated that the cytoplasmic expression of lamins in Purkinje cells begins during postnatal development.
