A novel neuro-muscular marker for the heavy subunit of neurofilament proteins, NF-H, and striated muscle myosin of Xenopus laevis☆

AbstractA novel monoclonal antibody, M7, is described, that reacts on Western blots with the large subunit of the neurofilament triplet proteins (NF-H) and with striated muscle myosin of Xenopus laevis. Enzymatically digested neurofilament and myosin proteins revealed different immunoreactive peptide fragments on Western blots. Therefore, the antibody must react with immunologically related epitopes common to both proteins. Immunohistochemistry showed staining of large and small axons in CNS and PNS, and nerves could be followed into endplate regions of skeletal muscles. These muscles were characterized by a striated immunostaining of the M-lines. Despite the crossreactivity of M7 with NF-H and muscle myosin, this antibody may be a tool to study innervation of muscle fibers, and to define changes in the neuromuscular organization during early development and metamorphosis of tadpoles.

Neurofilament triplet proteins are restricted to a subset of neurons in the rat neocortex

AbstractThe cellular localisation of neurofilament triplet subunits was investigated in the rat neocortex. A subset of mainly pyramidal neurons showed colocalisation of subunit immunolabelling throughout the neocortex, including labelling with the antibody SMI32, which has been used extensively in other studies of the primate cortex as a selective cellular marker. Neurofilament-labelled neurons were principally localised to two or three cell layers in most cortical regions, but dramatically reduced labelling was present in areas such as the perirhinal cortex, anterior cingulate and a strip of cortex extending from caudal motor regions through the medial parietal region to secondary visual areas. However, quantitative analysis demonstrated a similar proportion (10–20%) of cells with neurofilament triplet labelling in regions of high or low labelling. Combining retrograde tracing with immunolabelling showed that cellular content of the neurofilament proteins was not correlated with the length of projection. Double labelling immunohistochemistry demonstrated that neurofilament content in axons was closely associated with myelination. Analysis of SMI32 labelling in development indicated that content of this epitope within cell bodies was associated with relatively late maturation, between postnatal days 14 and 21. This study is further evidence of a cell type-specific regulation of neurofilament proteins within neocortical neurons. Neurofilament triplet content may be more closely related to the degree of myelination, rather than the absolute length, of the projecting axon.

Differential distribution of MAP1A isoforms in the adult mouse barrel cortex and comparison with the serotonin 5-HT2A receptor

AbstractMicrotubule-associated protein 1A (MAP1A) is essential during the late differentiation phase of neuronal development. Here, we demonstrated the presence of two MAP1A isoforms with a differential spatial distribution in the adult mouse barrel cortex. Antibody A stained MAP1A in pyramidal and stellate cells, including dendrites that crossed layer IV in the septa between barrels. The other antibody, BW6 recognized a MAP1A isoform that was mainly confined to the barrel hollow and identified smaller caliber dendrites. Previously, an interaction of MAP1A and the serotonin 5-hydroxytryptamine 2A (5-HT2A) receptor was shown in the rat cortex. Here, we identified, by double-immunofluorescent labeling, MAP1A isoform and serotonin 5-HT2A receptor distribution. MAP1A co-localized mainly with 5-HT2A receptor in larger apical dendrites situated in septa. This differential staining of MAP1A and a serotonin receptor in defined barrel compartments may be due to changes in the expression or processing of MAP1A during dendritic transport as a consequence of functional differences in processing of whisker-related sensory input.
