ACE inhibitors should not be discontinued over fears about COVID-19, say researchers

Researchers in Europe have found no evidence to support previous reports that the use of drugs that target the renin-angiotensin-aldosterone system (RAAS) increases susceptibility to coronavirus disease 2019 (COVID-19). The research is published in the European Heart Journal.

New discovery could end chronic rejection of transplanted organs

Chronic rejection of transplanted organs is the leading cause of transplant failure, and one that the field of organ transplantation has not overcome in almost six decades since the advent of immunosuppressive drugs enabled the field to flourish.

More selective elimination of leukemic and hematopoietic stem cells

Acute myeloid leukemia is an aggressive cancer of the blood-forming system. It affects the hematopoietic stem cells, or blood stem cells, of various white blood cells and of the red blood cells and platelets.

Protein shredder in brain cells indirectly regulates fat metabolism

A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism.

Study sheds light on how a cellular pathway in plants senses danger signals

In nature, every species must be equipped with a strategy to be able to survive in response to danger. Plants, too, have innate systems that are triggered in response to a particular threat, such as insects feeding on them.

Novel anti-cancer medicine could improve current therapy for ER+ breast cancer

The anti-cancer medicine venetoclax could improve the current therapy for estrogen receptor-positive breast cancer - the most common form of breast cancer in Australia - according to preclinical studies led by Walter and Eliza Hall Institute researchers.

Pangolins may be the key to new COVID-19 treatments

Researchers at the Medical University of Vienna, Austria, have made an important discovery about the immune response to coronaviruses in pangolins that could point to new approaches for treating human cases of infection.

Predicting the dose for repurposing nitazoxanide in COVID-19

A new study published on the preprint server medRxiv in May 2020 reports a model that could help evolve appropriate dosage protocols for future clinical trials of the repurposed drug nitazoxanide in COVID-19 prevention and treatment. The researchers say, “It was possible to achieve plasma and lung tizoxanide concentrations, using proven safe doses of nitazoxanide, that exceed the EC90 for SARS-CoV-2.”

Twist Bioscience Identifies Competitive Antibodies for SARS-CoV-2

Twist Bioscience Corporation has identified competitive antibodies to SARS-CoV-2, which could potentially be used for diagnostic tests and treatments.

Study: Genes may play a far more complex role in oocyte maturation than previously assumed

Over the last six years a group of Estonian geneticists led by Associate Professor Agne Velthut-Meikas and a PhD student Ilmatar Rooda from TalTech Department of Chemistry and Biotechnology have studied genes previously associated primarily with female hormone synthesis and ovarian follicle development.

Study discovers inhibition of SARS-CoV-2 entry priming protein by approved drug

The COVID-19 pandemic caused by the severe acute respiratory syndrome -coronavirus 2 (SARS-CoV-2) has spread to most of the world, causing millions of cases and hundreds of thousands of deaths. A new study published on the preprint server bioRxiv* shows that a protease inhibitor drug already approved by the Food and Drug Administration (FDA) could inhibit viral entry.

Low CD8 and NK cell counts in the lung linked to high SARS-CoV-2 ACE2 receptor levels

A new study published on the preprint server bioRxiv in April 2020 reports that low levels of specific immune cells, namely, CD8 T cells and NK cells, are linked to higher expression of the ACE2 molecule, which acts as a receptor for the CoV.

Scientists identify unexpected player that causes vision loss in patients with AMD

Scientists have identified an unexpected player in the immune reaction gone awry that causes vision loss in patients with age-related macular degeneration (AMD), according to a new study published today in eLife.

Caffeine consumption can protect against Parkinson’s disease, shows study

Two purines, caffeine and urate, have been associated with a reduced risk of Parkinson's disease (PD) in multiple study groups and populations.

Is ACEI, ARB use linked to testing positive for COVID-19?

A new study published in the prestigious journal JAMA Cardiology in May 2020 reports that there is no association between the use of ACEIs/ARBs and testing positive for COVID-19. This supports current medical advice to continue using these drugs as indicated irrespective of the ongoing pandemic but indicates the need for more research to rule out any additional risk of severe illness due to these agents.

SARS-CoV-2 genome shows mutation hotspots and type-specific distribution

Now, a new study published on the preprint server bioRxiv reports on a large scale analysis of SARS-CoV-2 genomes and reveals a clonal geo-distribution and rich genetic variations.

COVID-19 infection risk and outcomes explained by the cell receptor genetic variability

Genetic variants in the angiotensin‐converting enzyme 2 (ACE2) receptor, utilized by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) for cell entry, are predicted to either encourage or inhibit interaction with viral proteins and subsequently contribute to genetic risk in coronavirus disease (COVID-19). This is the key finding of a new study available on the preprint server bioRxiv*.
