Novel altruistic stem cell defense mechanism may be targeted to develop new COVID-19 vaccines
The SARS-CoV-2 virus that causes COVID-19 may have the ability to reactivate dormant tuberculosis (TB). In a novel study scientists report in
The American Journal of Pathology that infection with a specific coronavirus strain reactivated dormant Mycobacterium tuberculosis (MTB) in mice. This knowledge may help to develop new vaccines for COVID-19 and avoid a potential global tuberculosis epidemic.
The COVID-19 pandemic caused by the SARS-CoV-2 virus demonstrates the ability of an emerging virus to affect masses and strain and disrupt the workings of modern healthcare systems around the world. A significant number of infected COVID-19 individuals have recovered. However, a possible host defense or antiviral mechanism against the virus is yet to be identified. There are concerns that in the long-term, the virus might activate dormant bacterial infections such as TB in select infected indiv

Researchers make ‘bombshell’ discovery of an entirely new kind of biomolecule
A newfound biomolecule, consisting of RNA modified by sugars, could be present in all forms of life and might contribute to autoimmune disease. By Holly Alyssa MacCormick
Stanford researchers have discovered a new kind of biomolecule that could play a significant role in the biology of all living things.
The novel biomolecule, dubbed glycoRNA, is a small ribbon of ribonucleic acid (RNA) with sugar molecules, called glycans, dangling from it. Up until now, the only kinds of similarly sugar-decorated biomolecules known to science were fats (lipids) and proteins. These glycolipids and glycoproteins appear ubiquitously in and on animal, plant and microbial cells, contributing to a wide range of processes essential for life.
