Abstract：
:To examine whether the 200-kDa neurofilament protein (200K NFP) is involved in mechanically stabilizing axons, we studied the developmental appearance of immunoreactivity to nonphosphorylated and phosphorylated 200K NFP at the neuromuscular junction. Polyinnervated rat muscle fibers become singly innervated during the first 3 weeks of postnatal life through the process of synapse elimination. If production or post-translational modification of the 200K NFP is actively involved in imparting mechanical stability on neuromuscular synapses, then the selective presence of this protein in only one of several axons at each developing end plate region might make that one axon selectively resistant to elimination. The remaining axons would then be eliminated. Immunoreactivity to the 200K NFP is present on Gestational Day 14 and can be seen in more than one preterminal axon in the end plate region of a muscle fiber during the period of synapse elimination. These results suggest that the 200K NFP is present and phosphorylated early in development and, although the 200K NFP may increase the mechanical stability of axons, this increased stability does not determine the final outcome of synapse elimination.
