Study explores individual differences of SARS-CoV-2 infection in ACE2-expressing stem cells

The clinical phenotype of COVID-19, caused by SARS-CoV-2, is remarkable for its wide range of severity among individual patients. Genetic variations are known to mediate part of these differences. To examine these differences, researchers in a new study used human induced pluripotent stem cells (iPSCs) from different genetically diverse individuals. These cells are used to model genetic disease since they contain the donor’s genetic information. Researchers use a panel of iPSCs from over 500 individuals. The researchers preferred undifferentiated iPSCs to reduce the time required to differentiate them, especially since infection is not always reliable.

Virus transmission by dental tools and prevention by antiviral agent

Researchers at the University of Ljubljana have demonstrated how a virus can spread by droplets during ultrasonic scaler (USS) operation and how this spread can be mitigated by merely substituting the irrigant with clinical virucidal agents, namely sodium hypochlorite and EOW (Electrolyzed Oxidizing Water).

Artemisia plant extracts show potential anti-SARS-CoV-2 activity in vitro

A team of scientists from Germany and the USA recently explored the effectiveness of traditional plant medicines in treating SARS-CoV-2 infection.

Insight into role of aging in response to SARS-CoV-2 infection

Researchers at the University of California, Irvine set out to determine the differences between young people and older adults regarding their host responses against SARS-CoV-2. The team revealed that independent of disease severity, COVID-19 was linked to a significant shift in plasma inflammatory factors. The research is posted to the pre-print server medRxiv*.

Oxysterol derivatives show powerful antiviral activity against SARS-CoV-2 in vitro

A new study describes the antiviral activity of oxysterols, or oxidized cholesterol derivatives, against SARS-CoV-2. These occur in nature, and are not only involved in lipid signaling pathways that modulate a host of processes within the body, including the immune response and lipid homeostasis.

Combining anti-tumor antibodies with standard-of-care improves therapeutic outcomes in cancer

The cover for issue 2 of Oncotarget features Figure 4, "Combination therapy TA99/ICB reduced the lung tumor burden in the B16 model of metastases," published in "Improved therapeutic efficacy of unmodified anti-tumor antibodies by immune checkpoint blockade and kinase targeted therapy in mouse models of melanoma" by Pérez-Lorenzo, et al. which reported that here, the authors showed that removing immune suppression and enhancing stimulatory signals increased the anti-tumor activity of unmodified TA99 antibodies with a significant reduction of growth of solid tumors and lung metastases in mouse models of melanoma.

Transcriptional regulator BRD2 as a potential therapeutic target for COVID-19

A team of international scientists has demonstrated that therapeutic inhibition of a transcriptional regulator BRD2, required for the endogenous expression of angiotensin-converting enzyme 2 (ACE2), can potentially suppress severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study is currently available on the bioRxiv* preprint server.

Modified natural killer cells show neutralizing and multivalent potential against SARS-CoV-2 in vitro

A new study suggests that modified natural killer cells, which express a chimeric antigen receptor using S309 antibody, can bind to and inactivate SARS-CoV-2 spike protein in vitro.

Could intranasal SARS-CoV-2 vaccines be a practical alternative to intramuscular shots?

The unchecked advance of COVID-19 has made it a top public health priority to produce a vaccine capable of inducing a safe and powerful protective response against its causative pathogen: SARS-CoV-2. An encouraging new study shows the immunogenicity, safety, and protective efficacy, of a Newcastle disease virus (NDV)-based intranasal vector vaccine in animal studies.

Antibody-Fc-mediated innate immunity shapes COVID-19 severity

A short paper that appeared recently on the preprint bioRxiv server pointed to a link between specific characteristics of anti-SARS-CoV-2 antibodies associated with the severity of COVID-19.

Are SARS-CoV-2 antibodies associated with disease enhancement?

As SARS-CoV-2 continues to wreak its havoc, antibodies that neutralize the virus and protect against infection have become an important focus of research. However, there is a concern as to whether these antibodies can actually enhance the disease.

Glycyrrhizin in licorice root neutralizes SARS-CoV-2 in vitro by inhibiting the main protease Mpro

In a recent bioRxiv* preprint paper, researchers from Germany analyzed aqueous licorice root extract for its neutralizing activity against SARS-CoV-2 in vitro. They identified glycyrrhizin, the primary active ingredient in the root, and revealed the underlying mechanism of viral neutralization.

A common compound in mouthwashes found to inhibit SARS-CoV-2 in vitro

Researchers found that cetylpyridinium chloride, found in most mouthwashes, lowers infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro, likely by inhibiting viral fusion with target cells. With more tests to prove validity, mouthwashes could be a simple, cheap way of curbing transmission.
