title: Differential localization of microtubules in cerebellar cells.
abstract: The distribution and subcellular localization of microtubules in rat brain cerebellum was analyzed by immunohistochemistry with antibodies prepared against 3 synthetic peptides corresponding to the C-terminal region of beta-tubulin. The peptides used correspond to amino acid positions 416-425 (peptide 1), 416-431 (peptide 2), and 426-445 (peptide 4). The antibodies thus obtained displayed a remarkable specificity in reacting with different cell types in the rat cerebellum. Antibodies directed against peptide 1 primarily stained Purkinje cells and their dendrites and axons. Peptide 2 antibodies preferentially stained the glomeruli, while antibodies directed against peptide 4 preferentially stained Bergmann glial fibers. These results are discussed in terms of dissimilarities in microtubule organization and masking of epitopes by microtubule-associated proteins (MAPs) in individual cerebellar cells, which may be related to specific functional properties.
