Platelet inhibitors may be linked with reduction in digital ulcers in people with systemic sclerosis

New research presented this week at ACR Convergence, the American College of Rheumatology's annual meeting, shows that use of platelet inhibitors could be associated with a reduction in the occurrence of digital ulcers, painful sores on the extremities that can progress to gangrene, in people with systemic sclerosis.

Researchers discover protein previously unknown to be involved in SARS-CoV-2 infection

Researchers in the UK and Germany have provided evidence for a novel mechanism by which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – binds to human host cells.

Research suggests current smokers not at excess risk of SARS-CoV-2 infection

Now, a new study published on the bioRxiv* preprint server investigates this relationship further and suggests that current smoking is not associated with a higher incidence of SARS-CoV-2 infection.

Researchers identify the spleen as primary site for priming of 'killer' T cells during influenza infection

CD8+ T cells -; known as "killer" T cells -; are the assassins of the immune system. Once they are primed, they seek out and destroy other cells that are infected with virus or cells that are cancerous.

New analytical method visualizes cell functions in vasculature-on-a-chip

A microphysiological system (MPS), also known as an organ-on-a-chip, is a 3D organ construct using human cells that help reveal how organs respond to drugs and environmental stimuli.

New bioengineered lung model could help scientists to advance research in lung conditions

An interdisciplinary team of researchers from McMaster and SickKids are developing a cutting-edge lung model that can better respond to viruses and drug treatments, giving scientists a tool to advance research in lung conditions like COVID-19, cystic fibrosis and allergens for asthma and air pollution.

What is the potential of microphysiological systems in COVID-19 research?

In a recently published review article in the journal Drug Discovery Today, scientists have described the utility of human-based microphysiological systems MPSs in understanding the pathophysiology of SARS-CoV-2 infection and developing effective therapeutic interventions. Moreover, they have described the establishment of a global working group to synchronize recent developments around MPSs and COVID-19 research.

Researchers develop two complementary bladder models to study UTIs

Urinary tract infections (UTIs) are among the most common bacterial infections. They usually require treatment with antibiotics, and almost a quarter of treated cases lead to recurrent infection.

Injecting mice with pulmonary endothelial cells can reverse symptoms of emphysema

Researchers at Weill Cornell Medicine and NewYork-Presbyterian in New York have discovered that injecting mice with pulmonary endothelial cells-the cells that line the walls of blood vessels in the lung-can reverse the symptoms of emphysema.

How SARS-CoV-2 infects the brain

While there is no official explanation on how SARS-CoV-2 travels to the brain, a new review published in the journal Fluids and Barriers of the CNS concluded that there is insufficient evidence on COVID-induced neurological problems coming from a direct invasion of SARS-CoV-2 into the brain.

Novel optical device could open new avenues in advanced microscopy

What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality? What if it could provide views from multiple directions in real time without physically moving the specimen and worked up to 100 times faster than current technology?

New technology predicts effectiveness of chemotherapy after one treatment

While early detection of breast cancer is critical, early prediction of how well the neoadjuvant chemotherapy treatment before surgery is working also may provide a window of opportunity when treatment could be altered and have a big impact on the patient's quality of life.

Novel antibody engineering approach

Scientists from the Johns Hopkins University School of Medicine, USA, have recently developed an Antibody Display technology by grafting the second extracellular domain of tetraspanin12 (Tspan12EC2) and the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein on the heavy chain complementarity-determining region 3 (CDR3).

Antithrombotic endothelial dysfunction is prevented by Tie2 activation in severe COVID-19

Researchers from the US recently assessed if severe COVID-19 is linked to procoagulant dysfunction of the endothelium and changes in the Tie2-angiopoietin axis. They assessed circulating endothelial markers in a study cohort of 98 patients with mild, moderate, or severe COVID-19. This study is published on the medRxiv* preprint server.
