New SERS-based sensor can detect influenza A viral pathogens with high reproducibility

Respiratory diseases like influenza can spread rapidly and escalate to global health crises. Thus, to control them, simple yet sensitive detection techniques are needed. Surface-enhanced Raman scattering (SERS) is a potential candidate but currently lacks reproducibility.

New data on impact of spike mutations and B117 UK variant on neutralization by mAbs and sera

A recent paper by British and Dutch scientists, currently available on the bioRxiv* preprint server, shows that the neutralizing activity of monoclonal antibodies can be dramatically reduced by mutations of the SARS-CoV-2 spike glycoprotein – unlike polyclonal antibodies generated after natural infection that remain active regardless of any introduced amino acid changes.

Can cancer patients receive urgent care without risk of COVID-19?

A new study describes how a successful application of mitigation techniques to prevent COVID-19 transmission to cancer patients admitted to or attending a healthcare facility might look.

South African SARS-CoV-2 variant escapes antibody neutralization

Researchers in South Africa have conducted a study showing that the novel 501Y.V2 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has emerged in the country is able to escape the neutralizing antibodies that are elicited by previously circulating strains of the virus.

Mapping antibody reactivity in COVID-19 patients by using multi-coronavirus protein microarray

In an exciting, state-of-the-art study currently available on the medRxiv* preprint server, US researchers created a multi-coronavirus protein microarray containing full-length proteins, peptide libraries, and overlapping protein fragments from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as four other human coronaviruses.

Lower CD4 T cell reactivity to seasonal coronaviruses found in healthcare workers with COVID-19

A new study by US-based researchers describes the results of a study on the immune response among healthcare workers, in particular, their T cell responses predating the pandemic.

Scientists develop world's first test to accurately predict mood disorders

University of South Australia scientists have developed the world's first test to accurately predict mood disorders in people, based on the levels of a specific protein found in the brain.

SARS-CoV-2 anti-N rigid monoclonal antibodies provide accurate early diagnosis

An interesting new preprint research paper that was posted on the bioRxiv* server recently describes the use of rigid monoclonal antibodies (mAbs) in contrast to flexible mAbs, and how this affects the binding of multiple mAbs to the same antigen.

How do SARS-CoV-2 antibodies change over time in recovered patients?

Researchers studied convalescent plasma from recovered coronavirus disease 2019 (COVID-19) patients, with samples collected up to 34 weeks after recovery. They found IgG antibodies gradually declined with a median half-life of about 60 days.

Antibodies and inflammatory markers are pervasive in colostrum of SARS-CoV-2 infected women

A recent study, currently available on the medRxiv* preprint server, is among the first to reveal the presence of antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in colostrum and to demonstrate elevated cytokine levels in colostrum from women exposed to the virus.

Higher BMI linked to increased risk of SARS-CoV-2 infection

Researchers at the University of Miami Miller School of Medicine, USA, revealed that the spike-specific immunoglobulin G antibodies in obese people are negatively associated with body mass index (BMI) and serum levels of proinflammatory and metabolic markers of pulmonary inflammation.

SARS-CoV-2 antibody levels and types differ by disease severity, study finds

Researchers have measured the antibody levels and types in hospitalized coronavirus disease 2019 (COVID-19) patients with different disease severity. Their results suggest gut immune pathways could play a role in reducing virus-based inflammation and recovery.

Scientists identify new Salmonella proteins

Salmonella are bacteria that can cause food poisoning with severe diarrhea. If they penetrate from the intestine into the blood system, this can lead to sepsis, life-threatening inflammatory reactions in the entire organism.

Study suggests vast majority of Seattle population remains susceptible to COVID-19

Researchers in the United States have conducted a study suggesting that a small proportion of people living in Seattle were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – by around late March/early April 2020.

Different SARS-CoV-2 neutralization assays are reliable and concordant for antibody monitoring

A recent study by US researchers, currently available on the medRxiv preprint server, evaluated several cell-based assays that are under validation for determining correlates of protection in individuals with symptomatic coronavirus disease (COVID-19) and vaccine studies – and demonstrated their high concordance with both live and pseudotyped virions.
