A SARS-CoV-2 ferritin nanoparticle vaccine elicits broad immunity

In a recent bioRxiv* preprint research paper, M. Gordon Joyce et al. designed engineered nanoparticle immunogens that recapitulate the structural and antigenic properties of prefusion Spike (S), S1 and receptor-binding domain (RBD). They demonstrated that these immunogens induced robust S-binding, ACE2 (angiotensin-converting enzyme)-inhibition, and authentic and pseudovirus neutralizing antibodies against SARS-CoV-2 in mice.

A magnetofluidic platform for SARS-CoV-2 variant and respiratory pathogen detection

Recent research published on the medRxiv* server has developed a portable, magnetofluidic cartridge platform, for automated PCR testing in <30 min, for rapid multiplexed screening of pathogens. A multidisciplinary team of researchers at Johns Hopkins University and the Johns Hopkins University School of Medicine developed these cartridges for multiplexed detection of SARS-CoV-2 with distinctive variant mutations or with Influenza A and B.

Three-way strategy employed by SARS-CoV-2 during infection

The study, published in the journal Nature, reveals a multi-pronged strategy that the virus employs to ensure its quick and efficient replication while evading the immune system. The study elucidated how the virus can quickly, in a matter of hours, take over the cell's protein-making machinery and parallelly neutralize the cell's antiviral signaling, thus delaying and muddling the immune response.

Dominance of South African SARS-CoV-2 variant in the US is unlikely but possible

Researchers in the United States and Canada have conducted a study showing that the South African variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – is unlikely to become the dominant strain in the US.

Antibodies generated by malaria cross-react with SARS-CoV-2

An international team of researchers has warned that individuals with acute malaria infection generate high levels of antibodies that cross-react with the viral spike protein of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Immunity developed by SARS-CoV-2 infection can protect against E484K variants, suggests study

A team of scientists from Japan has recently investigated the neutralizing potency of convalescent sera against currently circulating SARS-CoV-2 variants with multiple spike mutations.

Single dose of Oxford-AstraZeneca vaccine protective in previously infected recipients, suggests study

A recent report on the medRxiv* preprint server suggests that a single dose of the Oxford-AstraZeneca (ChAdOx1 nCoV-19) vaccine could elicit higher titers of neutralizing antibodies, effectively acting as a booster dose, in people who have already been infected by the SARS-CoV-2.

Phosphatidic acid is a key common substrate for hepatitis C and SARS-CoV-2 replication

A new study, released as a preprint on the bioRxiv* server, focuses on the lipid molecule called phosphatidic acid (PA), showing its crucial role in the replication of this virus, and thus its potential as a target for therapeutic intervention.

High-density microarray patch could help vaccinate for dengue in a single click

A dengue virus vaccine candidate has passed an important milestone, with promising results in animal model testing providing hope to the 390 million people infected every year.

Designer SARS-CoV-2 RBD vaccine produces dramatically improved antibody response in preclinical trials

The importance of computational modeling in the prediction of the course of the ongoing COVID-19 pandemic, as well as evaluating multiple potential drug leads, has never been more clear. Now, a new study describes a set of designer vaccine antigens that may improve vaccine stability as well as enhance the neutralizing antibody response.

Huge healthcare burden of post-COVID-19 symptoms likely, suggests new study

How well do patients who had COVID-19 recover after the virus is cleared from their systems? A new preprint reports on symptom profiles over the first nine months of the illness.

Black fungus complicates India's COVID pandemic

India faces a global health crisis as the number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections reaches over 23.7 million. As India's health system buckles with increased admissions and a lack of resources, another health threat has emerged.

SARS-CoV-2 virus uses a multipronged strategy to avoid detection by the immune system

Severe symptoms of COVID-19, leading often to death, are thought to result from the patient's own acute immune response rather than from damage inflicted directly by the virus.

Researchers use ultrasound to reduce COVID-19-related inflammation

Researchers at University of California San Diego School of Medicine have begun a pilot clinical trial to test the efficacy of using ultrasound to stimulate the spleen and reduce COVID-19-related inflammation, decreasing the length of hospital stays.
