Many different T cell receptors recognize SARS-CoV-2 antigenic sites

The global COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spreading over the world. However, not much is known about how the adaptive immune response kicks in following the viral challenge. This knowledge is crucial to predicting the efficacy of a vaccine and estimating the chances of reinfection.

Heparin resistance among COVID-19 patients admitted to ICU

A new study has shown that COVID-19 patients admitted to the Intensive care unit may be resistant to the naturally occurring anticoagulant Heparin. The study titled, “Heparin resistance in COVID‑19 patients in the intensive care unit,” was published in the latest issue of the Journal of Thrombosis and Thrombolysis.

Research could help identify disturbances in the body's copper metabolism

In biology it is well-known that every living organism is triggered by the hereditary material or DNA that encodes various protein molecules, which in turn perform all the necessary biological functions and it might seem that nothing else is needed to sustain the life of an organism.

Majority of people in Vancouver’s Downtown Eastside use cannabis for therapeutic reasons

Most people at high risk of overdose in Vancouver's Downtown Eastside who use cannabis do so for pain relief and other therapeutic reasons--and they may be at lower risk of overdosing on opioids as a result, suggests new research published in the peer-reviewed journal PLOS ONE.

Collagen maturation regulates PEDF availability, study shows

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific receptors on the cell surface, stimulating signaling pathways and altering gene expression.

Study shows antihypertensive drugs do not raise serum levels of ACE2

A new study published on the preprint server medRxiv* by researchers from Iceland and the U.S. shows how treatment with angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) does not raise angiotensin-converting enzyme 2 (ACE2) levels in human serum – and cautions against the discontinuation of these drugs among patients affected with coronavirus disease (COVID-19).
