Special Issue: Coronaviruses and the Cytoskeleton Note from the Editor:  How does SARS-CoV-2 enter and navigate host cells? While this complex process remains elusive for a number of human betacoronaviruses, published studies on related viruses may serve as a springboard for understanding the infection and pathogenicity of the novel coronavirus underlying COVID-19.  We have distilled …

The cell exhibits remarkable spatiotemporal control over its molecular constituents. Much of the cell’s internal organization was previously thought to arise from the inheritance of an already ordered state. However, in this study, Cheng and Ferrell perform an elegant experiment demonstrating the ability of cytoplasm to organize de novo based largely on microtubule polymerization dynamics and dynein-mediated transport.

Oligodendrocytes extend dozens of protrusions that envelop neighboring axons in insulating myelin sheaths. An intriguing population of lamellar microtubules spiral around the myelin sheath and are linked to diseases of hypomyelination, yet the intricacies of this complex microtubule architecture are unknown.
