Silencing rapsyn in vivo decreases acetylcholine receptors and augments sodium channels and secondary postsynaptic membrane folding
2009, Neurobiology of DiseaseCitation Excerpt :Quantitative morphometric analysis confirmed a significantly increased length of the postsynaptic membrane relative to the presynaptic membrane (folding index; Fig. 4D). The folding index showed considerable variation in the tibialis anterior muscle, which is possibly due to differential specialization of the postsynaptic membrane in type I and type II fibers (Pachter and Eberstein, 1984, 1986). The area of postsynaptic folds was increased and the nerve terminal size was slightly, but significantly decreased in rapsyn-silenced muscles (Table 2; p < 0.05).
Effects of short duration static stretching on the denervated and reinnervated soleus muscle morphology in the rat
2003, Archives of Physical Medicine and RehabilitationCitation Excerpt :Previously reported data1 indicate that rhythmic stretching and the associated increase in mechanical loading can attenuate the marked morphologic adaptations that characterized the denervated skeletal muscle. Pachter and Eberstein22 observed that immobilization of the denervated muscle in a stretched position led to an increased postsynaptic area of junctional folds and clefts per nerve terminal. In contrast, Deschenes et al7 stated that the mechanical stimuli were not sufficiently potent to ameliorate the muscle morphometric responses to the denervation.
