US scientists have found the first direct evidence that coronavirus could infect the human brain and replicate inside its cells on.ft.com/37xIUBW
Toxicology experts at Johns Hopkins University made the discovery after adding low levels of Sars-Cov-2, the virus responsible for Covid-19, to tiny neuronal balls known as mini-brains on.ft.com/37xIUBW 
The research showed once the virus entered neurons in the mini-brains, it was able to increase its number of copies ten-fold in just 3 days on.ft.com/37xIUBW
If the virus can attack the human brain, it has to get past the blood-brain barrier that shields the organ against many viruses and chemicals and often prevents infections on.ft.com/37xIUBW
‘Whether or not the Sars-Cov-2 virus passes this barrier has yet to be shown,’ says Prof Thomas Hartung, ‘but it is known that severe inflammations make the barrier disintegrate’ on.ft.com/37xIUBW
