The coronavirus that causes COVID-19 can sometimes hijack brain cells, using the cells’ internal machinery to copy itself, according to a new study.
The research, posted Sept. 8 to the preprint database bioRxiv, has not yet been published in a peer-reviewed journal, but it provides evidence that SARS-CoV-2 can directly infect brain cells called neurons. Although the coronavirus has been linked to various forms of brain damage, from deadly inflammation to brain diseases known as encephalopathies, all of which can cause confusion, brain fog and delirium, there was little evidence of the virus itself invading brain tissue until now.
“We are actively looking at more patient tissues to be able to find how frequently such brain infections occur … and what symptoms correlate with infection of which areas of the brain,” senior author Akiko Iwasaki, an immunologist at Yale University, told Live Science in an email. In addition, scientists must still figure out how the virus enters the brain in the first place, and whether it can be kept out of the brain, the authors noted in their report.
Human, mouse and mini-brains
To see whether SARS-CoV-2 could break into brain cells, the study authors examined autopsied brain tissue from three patients who died of COVID-19. They also conducted experiments in mice infected with COVID-19 and in organoids — groups of cells grown in a lab dish to mimic the 3D structure of brain tissue.
“This study is the first to do an extensive analysis of SARS-CoV-2 [brain] infection using three models,” said Dr. Maria Nagel, a professor of neurology and ophthalmology at the University of Colorado School of Medicine, who was not involved in the study. Previously, there were only “rare case reports” of SARS-CoV-2 RNA and viral particles found in post-mortem tissue from patients, Nagel, who specializes in neurovirology, told Live Science in an email.
In the organoids, the team found that the virus could enter neurons through the ACE2 receptor, a protein on the cell surface that the virus uses to enter the cell and trigger infection. They then used an electron microscope, which uses beams of charged particles to illuminate the tissue, to peer inside infected cells. They could see coronavirus particles “budding” within the cell, demonstrating that the virus had commandeered the neurons’ internal machinery to build new copies of itself.
