...es of CMT2 arise from mutations in a mitochondrial fusion
protein mitofusin 2 (MFN2). This week, Baloh et al. propose that MFN2 mutations cause disease by altering mitochondrial trafficking. The authors expressed mutant MFN2 in cultured dorsal root ganglion neurons. Fragmented mitochondria clustered in cell...
Together, biological membranes prevail
...ign have developed a novel method to visualize the fusion
of biological membranes at the single-event resolution. Observing the individual fusion
