Which vitamins and minerals help with COVID?

A study published in the journal Inflammopharmacology reviewed recent data related to the role of vitamins and minerals in treating COVID-19 patients. The primary goal of the review is to highlight the possible therapeutic role of vitamins A, B, C, D, E and K, and micronutrients as immunity boosters in COVID-19 patients.

Antibody combination REGEN-COV prevents symptomatic disease following SARS-CoV-2 infection

Researchers in the United States have demonstrated the effectiveness of early treatment with REGEN-COV™ at preventing symptomatic disease among people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Long-term exposure to poor air quality increases COVID-19 risk, research finds

Even as governments across the United States consider lifting mask mandates and relaxing preventative measures as vaccination numbers creep up, new research from a UCLA-led team has found that such basic techniques significantly reduce the risk of getting COVID-19.

Study observes increased breadth of SARS-CoV-2 antibody neutralization acquired over one year

A new paper in the journal Nature offers a reassuring answer, showing that convalescent COVID-19 patients, some of whom had received vaccination as well, retain antiviral antibodies and neutralizing activity, as well as memory B cells, for up to 6-12 months from infection.

Cissampelos pareira (velvetleaf) exhibits anti-SARS-CoV-2 potential

Cissampelos pareira (Cipa), also known as velvetleaf, is a widely used hormone modulator used to treat reproductive disorders and fever. Research has shown that it can inhibit three serotypes of Dengue virus (DENV) and affect various hormones.

A study on SARS-CoV-2 proteins for the development of COVID-19 drugs

The authors of the review have grouped the virus proteins into three categories, (a) host-entry, (b) self-acting, and (c) host-interacting. Additionally, individual SARS-CoV-2 proteins are evaluated to be either directly targeted by drugs or block virus-host interactions.

SARS-CoV-2 oral vaccine booster shows promise in animal tests

In a recent study published on the pre-print bioRxiv* server, a group of Israeli researchers discusses their progress towards developing an oral multi-antigen SARS-CoV-2 vaccine.

RBD and NTD antibody cocktail could prevent the emergence of SARS-CoV-2 escape mutants

A new bioRxiv* preprint demonstrates how a combination of antibodies to two different regions on the viral spike could enhance neutralization efficiency as well as prevent the emergence of resistant variants.

Fusogenicity and resistance of SARS-CoV-2 B.1.1.7 and B.1.351 compared to D614G

A new study, released as a preprint on the bioRxiv* server, describes the biological effects induced by mutations in two circulating VOCs. These are the alpha and beta strains, also called B.1.1.7 and B.1.351, respectively.

Potent antibodies against SARS-CoV-2 can be produced without T follicular helper cells, suggests study

It has been uncertain whether antibodies produced via this non-canonical pathway are protective against SARS-CoV-2. In a new study, recently released as a preprint on the bioRxiv*server, the neutralization potency of these antibodies is compared with those traditionally produced in germinal center-based antiviral responses.

Alkaloids show potential as treatments for COVID-19

To further study these organic compounds, researchers from Kermanshah University of Medical Sciences, Iran, and Universidad de Santiago de Chile, Chile, reviewed the role of alkaloids as a potential antiviral, specifically against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They presented the chemistry, plant sources, and antiviral effects of alkaloids and their anti-SARS-CoV-2 effect.

Immune memory responses differ between SARS-CoV-2 and influenza A

Researchers in Canada have shown that the long-lasting immunity that develops following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is characterized by different T cell responses than those observed for influenza A virus-specific immune memory.

Intranasal monoclonal SARS-CoV-2 antibody therapy shows promise in preclinical trials

A new study, released as a preprint on the bioRxiv* server, presents a new monoclonal antibody (MAb) called DZIF-10c that powerfully neutralizes SARS-CoV-2, including the current variants of concern (VOCs). With high bioavailability in the lungs and wide distribution in the body, the antibody was able to prevent SARS-CoV-2 infection in mice after intranasal administration.

Fatty acid binding site on SARS-CoV-2 spike triggers spike monomer crosstalk that is key to infectivity

A new study, released as a preprint on the bioRxiv* server, examines the role played by a fatty acid called linoleic acid (LA) that attaches at a binding site near the receptor-binding domain (RBD) of the spike protein. The spike exists as a homotrimer in open or closed conformations. In the former, at least one RBD points upwards.

Forkhead box O's potential therapeutic use in the treatment of COVID-19

In a recent study, Indian researchers from the Department of Biochemistry, University of Delhi, reviewed a possible vital coalition of FoxOs - the Forkhead Box O subfamily of protein transcription factors, with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), the etiological agent of COVID-19 (coronavirus disease).

What makes the elderly more susceptible to SARS-CoV-2 infection?

Why is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 (coronavirus disease 2019), biased towards infecting the aged population? A recently published study by Italian scientists linked aging, DNA damage, telomere shortening, and increased levels of angiotensin-converting enzyme 2 (ACE2) to this relationship.
