Study may help develop effective therapeutic strategies against COVID-19

Rss Feed - Thu, 10/22/2020 - 11:39
People have different susceptibilities to SARS-CoV-2, the virus behind the COVID-19 pandemic, and develop varying degrees of fever, fatigue, and breathing problems -- common symptoms of the illness. What might explain this variation?

Researchers use molecular dynamics simulations to identify secrets of SARS-CoV-2 virus

Rss Feed - Thu, 10/22/2020 - 11:36
The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells to contribute its machinery to assist in its propagation.

Researchers assess molecular basis of SARS-CoV-2 severity and poor outcomes in lung disease

Rss Feed - Thu, 10/22/2020 - 10:42
A recent study published on the preprint server bioRxiv in October 2020 shows that in patients with chronic lung disease, the pattern of gene expression in the different types of cell changes such that the lung epithelium is prepared to tackle SARS-CoV-2 infection. Also, the altered gene programs have an impact on the immune response.
