How does SARS-CoV-2 spread to the brain?

In a study led by researchers at the LSU Health Shreveport (LA, USA), scientists have discovered how SARS-CoV-2 can spread throughout the brain – unearthing the root cause of the severe neurological symptoms that are associated with COVID-19. Their research will be presented at the virtual American Physiological Society annual meeting during the Experimental Biology (EB) 2021 meeting (27–30 April 2021). Whilst COVID-19 is known primarily for causing severe respiratory symptoms, other baffling neurological symptoms have been reported, suggesting that SARS-CoV-2 can infect the nerve cells in the brain (neurons) and the cells in the brain and spinal cord that...
