Existing drug masitinib identified as potential inhibitor of SARS-CoV-2

Researchers in the United States have demonstrated that a drug originally developed as a treatment for cancer exhibits antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

ACE2/TMPRSS2 not expressed in pancreatic islet endocrine cells

A new study by researchers at the Vanderbilt University Medical Center and the University of Pennsylvania Perelman School of Medicine and published on the preprint server bioRxiv* in August 2020 reports that both key enzymes that are required for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) entry into the human host cell are lacking in the beta cells of the pancreatic islet. This rules out the direct injury hypothesis for impaired glucose control in patients with COVID-19 disease.

Negligible ACE2 expression in human beta-cells

Now, a new study published on the preprint server bioRxiv reports that even though the fatality rate is significantly higher in diabetics, there is no evidence that this is due to direct viral infection of pancreatic beta cells, which produce the key hormone in glucose homeostasis, namely insulin.

Promising new candidate 'virus-like particle' vaccine for COVID-19

Researchers in the UK and Taiwan have demonstrated the potential of a new candidate vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the virus responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

Common heart drugs are safe for patients hospitalized with COVID-19

Heart patients hospitalized with COVID-19 can safely continue taking angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), according to the BRACE CORONA trial presented in a Hot Line session today at ESC Congress 2020.

Brain estrogen critical for astrocyte activation and neuroprotection

When the brain isn't getting enough oxygen, estrogen produced by neurons in both males and females hyperactivates another brain cell type called astrocytes to step up their usual support and protect brain function.

Spike ferritin nanoparticles show potential as SARS-CoV-2 vaccine

Now, a new study published on the preprint server bioRxiv* in August 2020 reports the induction of neutralizing antibodies in mice by a single dose of a ferritin nanoparticle-based vaccine containing the spike protein.

$Sacubitril/valsartan therapy may reduce hospitalization in heart patients with preserved ejection fraction$

Sacubitril/valsartan therapy may reduce hospitalization in heart patients with preserved ejection fraction

Sacubitril/valsartan reduces NT-proBNP, a biomarker predictive of long-term clinical outcomes in heart failure, but does not improve functional capacity compared to individualized background therapy in patients with heart failure with preserved ejection fraction

14 existing drugs identified as SARS-CoV-2 main protease inhibitors

Now, a new study published on the preprint server bioRxiv in August 2020 reports on the identification of 14 compounds that can inhibit the key viral enzyme called the Main Protease (MPro) at micromolar concentrations.

Scientists explain why SARS-CoV-2 targets multiple organs

Now, a team of researchers at LSU Health New Orleans’ Neuroscience Center of Excellence and School of Medicine has explained the gateway receptor for SARS-CoV-2 and how it leads to the emergence of many complications as it targets many parts of the body.

COVID-19 patients may experience long-term cardiovascular complications

Researchers at the University of Washington in Seattle have conducted a study suggesting that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can directly infect heart tissue and contribute to whole-organ cardiac dysfunction.

Antihypertensive drugs are not linked to cancer, shows study

There is no evidence that blood pressure lowering drugs increase the risk of cancer, according to the most extensive study conducted on the topic. The late breaking research is presented today at ESC Congress 2020.

T cell epitopes from recovered COVID-19 patients identified for vaccine

A new study by researchers at The Hong Kong University of Science and Technology and published on the preprint server bioRxiv in August 2020 collates the available database of SARS-CoV-2 T cell epitopes gathered from 8 studies of COVID-19 patients who recovered. This could serve as a launchpad to fill in knowledge gaps regarding the immunological aspects of this disease, and drive towards an effective T cell vaccine.

DAPA-CKD trial shows dapagliflozin reduces risk of chronic kidney disease

Dapagliflozin reduces the risk of kidney failure, death from cardiovascular causes or heart failure hospitalization and all-cause mortality in chronic kidney disease patients with or without type 2 diabetes.

Premenopausal women have favorable long-term outcomes after heart attack, shows study

Premenopausal women have good long-term outcomes after a heart attack, according to late breaking research presented today at ESC Congress 2020.

New lipid derivatives of Remdesivir have higher anti-coronavirus activity

In a fascinating new preprint paper published on bioRxiv* in August 2020, the researchers report “the synthesis and antiviral evaluation of three novel lipophilic prodrugs of RVn-monophosphate that are substantially more active than Remdesivir in cells infected with SARS-CoV-2.” These could be of immense use in treating COVID-19 patients early and helping to end transmission.

Rabbits susceptible to SARS-CoV-2: Red flag for potential virus reservoir

A new study by scientists in the Netherlands and published on the preprint server bioRxiv* in August 2020 shows that the severe acute respiratory coronavirus-2 (SARS-CoV-2) can infect rabbits, which opens the door for possible circulation in rabbit farms and another potential source of animal to human SARS-CoV-2 infection. This finding calls for urgent research on the prevalence of the virus in farmed rabbits.

Study may help explain the symptoms and organs involved with SARS-CoV-2 infection

A study of a gateway receptor for SARS-CoV-2 led by Walter Lukiw, PhD, Professor of Neuroscience, Neurology and Ophthalmology at LSU Health New Orleans' Neuroscience Center of Excellence and School of Medicine, may help explain the wide variety of symptoms and organs involved with SARS-CoV-2 infection and COVID-19.
