Cellular and molecular evidence that synaptic Schwann cells contribute to aging of mouse neuromuscular junctions. [PDF]
Aging Cell, 2023 Age‐induced degeneration of the neuromuscular junction (NMJ) is associated with motor dysfunction and muscle atrophy. We found that the synaptic glia of the NMJ, known as perisynaptic Schwann cells (PSCs), are more abundant in aged mice, fail to completely cap the NMJ, and form processes that either intrude into the synaptic cleft or extend to ...

Age-Associated Dysregulation of Postsynaptic Mitochondria Perturbs Reinnervation Kinetics. [PDF]
Aging CellWe show that aging results in postsynaptic mitochondrial loss at the neuromuscular junction and impaired muscle reinnervation. In vivo CRISPR knockout of mitochondrial genes, CHCHD10 and CHCHD2, in young muscles led to fragmented endplates, aberrant innervation, and impaired transcriptional maturation of sub‐synaptic myonuclei during regeneration ...
