Coronavirus can infiltrate crucial brain cells, causing neurons to die: Study

SARS-CoV-2, vel coronavirus that causes COVID-19 can infiltrate star-shaped cells in brain furr triggering a chain reaction that may disable and even kill nearby neurons, claims a new study that is yet to be peer-reviewed. sheer ability of ‘virus to get re’ has been regarded as main mess of paper according to author of study Daniel Martins-de-Souza, and associate professor and he of proteomics in Department of Biochemistry at University of Campinas in Brazil.

As quoted by Live Science, de Souza said, “ main mess in paper is that virus is able to get re, [into astrocytes]...It doesn't get re every time, but it can get re.” star-shaped cells, called astrocytes are responsible for performing several roles including transmitting signals throughout body and brain. study, posted to preprint database medRxiv earlier this month, and an expert told Live Science that data is preliminary and it still needs to be verified with more enhanced research.

However, during research, in a lab dish, infected astrocytes ceased to produce critical fuel for neurons and secreted an “unidentified” substance that poisoned nearby neurons. If infected astrocytes behave similarly inside brain, it could explain some of structural changes that are witnessed in some of COVID-19 patients’ brains along with or issues such as “brain fog” and psychiatric issues. However, or studies have also ted that vel coronavirus can directly infect neurons but exact route of pathogen to brain is still under investigation.

COVID-19 antibodies last 6 months after infection

A separate study led by UK’s biomedical research body said that antibodies produced in body due to COVID-19 stay in system fo six months after infection. After studying biobank of more than 20,000 participants who h recovered from highly-infectious disease. UK Biobank said in a new study that 99% retained antibodies to coronavirus for three months post-infection and at least 88% did so for six months.
