Researchers develop a new method to remove old cells from tissues to slow down aging

No one knows why some people age worse than others and develop diseases -such as Alzheimer's, fibrosis, type 2 diabetes or some types of cancer- associated with this ageing process.

Broadly protective vaccines against coronaviruses needed to protect against future outbreaks

The coronavirus disease 2019 (COVID-19) pandemic, caused by the β-coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), alerted the world to the seriousness of the threat posed by novel viruses.

Children show lower seroconversion rates than adults with mild COVID-19

A new study finds that following mild COVID-19, children are more likely to remain seronegative than adults, irrespective of the viral load or symptom severity.

New research on phagocytosis and SARS-CoV-2's spike protein

A new study showed that convalescent patient plasma and monoclonal anti-spike antibodies were able to induce phagocytosis at high antibody concentrations.

The neutralization potential of nanobodies against SARS-CoV-2

A recent review describes the role of nanobodies as a new class of recombinant antibodies that are used in the treatment of COVID-19.

Scientists search for cause of mysterious covid-related inflammation in children

Like most other kids with covid, Dante and Michael DeMaino seemed to have no serious symptoms.

Safety and oral immunogenicity of a VSV-derived mucosal vaccine against SARS-CoV-2

A team of researchers exploited the known tropism of vesicular stomatitis virus to develop an oral vaccine that expresses the immunogenic SARS-CoV-2 spike glycoprotein in the oral mucosa.

Long-term predictions of immunity after two doses of mRNA vaccine

Researchers from York University has investigated the long-term protection of two mRNA vaccines.

BNT162b2 mRNA COVID-19 vaccine-induced antibodies wane over six month period

Researchers have been investigating the response of antibodies created against SARS-CoV-2 by the Pfizer-BioNTech six months after vaccination.

Microscopy-based high content platform for SARS-CoV-2 serological screening

A new study published on the medRxiv* preprint server used automated high content immunofluorescence microscopy (AHCIM) to assess the viability of such an approach to detect humoral immune responses against SARS-CoV-2 proteins.

The biochemical mechanisms of remdesivir-mediated RNA synthesis inhibition

A new preprint suggests a fruitful approach to develop such drugs based on biochemical and molecular modeling studies of the drug remdesivir.

Phase 2 trial shows COVID-19 recombinant protein vaccine elicits promising immunogenicity responses

Researchers performed a large-scale, double-blind, placebo-controlled phase two trial to assess the efficacy, safety, and immune response elicited from vaccination with MVC-COV1901.

Structural mechanism of anti-SARS-CoV-2 neutralizing antibodies that target separate spike epitopes

Researchers from the Washington University School Of Medicine have identified how a subset of variants of concern can escape neutralization by two neutralizing antibodies.

Nasal delivery of single-domain antibodies improves SARS-CoV-2 symptoms in animal model

In a recent study published in the journal PLOS Pathogens, scientists showed that nasal administration of a single-domain antibody (VHH), named K-874A, brought about inhibition of SARS-CoV-2 titers in infected lungs of Syrian hamsters.

Waning COVID vaccine efficacy especially against reinfection

A new study in American veterans posted to the medRxiv* preprint server suggests severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines are less effective in preventing infection after six months. The decline was most significant with the Johnson & Johnson vaccine, with vaccine effectiveness plummeting from 88% to 3%.

SARS-CoV-2 antibodies detected in breast milk of vaccinated mothers

Now, a new medRxiv* preprint study finds mothers vaccinated either one of the messenger RNA (mRNA) vaccines transferred neutralizing antibodies and cytokines, including interferon-gamma (IFNγ), to a breastfeeding child. Additionally, the humoral response in breastmilk was effective in neutralizing four variants of concern.
