Some viruses don't just hijack your cells—they physically smash the 'gates' of your DNA to kill you.

The Takeaway
Most viruses kill cells by turning them into little 'virus factories' until they burst, but some have a more direct, brutal method. This study shows how a virus uses a specific protein to physically chop up the 'nuclear pores'—the high-security gates that control what enters and leaves the cell's nucleus. When these gates are destroyed, the cell's vital machinery breaks down and the neuron dies, even if the virus doesn't manage to replicate itself. This discovery explains why certain viruses are so uniquely devastating to the nervous system. Understanding this 'smash-and-grab' tactic could help us develop new drugs to protect our brains from viral attacks. It's a literal physical assault on the cell's command center.
From the abstract
The picornavirus Enterovirus D68 (EV-D68) is an important pathogen associated with acute flaccid myelitis (AFM). The pathogenesis of AFM involves infection of spinal motor neurons and motor neuron death, however the mechanisms linking EV-D68 infection to selective neurotoxicity are not well understood. Dysfunction of the nuclear pore complex (NPC) has been implicated in motor neuron injury in neurodegenerative diseases such as amyotrophic lateral sclerosis, and the NPC is also modified by picorn
