Evidence of robust and persistent antibodies against SARS-CoV-2

A team of researchers from the Icahn School of Medicine at Mount Sinai, New York, have worked in collaboration to try and answer one of the most baffling questions surrounding the coronavirus disease 19 (COVID-19) pandemic: do antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) last after a primary infection?

SARS-CoV-2 T-cell immunity is retained for at least six months

Now, a new study published on the preprint server bioRxiv shows that functional SARS-CoV-2-specific T-cell responses are retained for six months following infection. However, the strength of this response depends on the clinical features of the primary infection.

Study finds a subset of quick COVID-19 healers and antibody 'sustainers'

One of the pressing questions about COVID-19 remains: How long does immunity last? One key indicator of immunity is the presence of virus-specific antibodies.

Rapid generation of divergent synthetic antibodies against SARS-CoV-2 in a cell-free engineering platform

In a groundbreaking bioRxiv paper, a research group from the Massachusetts Institute of Technology (MIT), Harvard University and Howard Hughes Medical Institute in the US engineered antibodies against the receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein by using a novel approach. In doing so, they also identified more than 800 predicted binder families.

Earwax sampling could be a cheap, effective way to measure stress hormone

A novel method to sample earwax could be a cheap and effective way to measure the hormone cortisol, according to a study led by researchers at UCL and King's College London.

Scientists identify neutralizing human monoclonal antibodies against SARS-CoV-2

University of Pittsburgh School of Medicine scientists have discovered the fastest way to identify potent, neutralizing human monoclonal antibodies against SARS-CoV-2, the virus that causes COVID-19.

Large differences in reported COVID-19 death rates can be misleading

Simply comparing the total number of deaths across countries may provide a misleading representation of the underlying level of transmission of SARS-CoV-2, the virus that causes COVID-19, because of large differences in reported COVID-19 death rates in elderly populations in different countries.

Microneedle patch for rapid, blood-free malaria testing

Testing for malaria could become as simple as putting on a bandage.

How COVID death counts become the stuff of conspiracy theories

In the waning days of the campaign, President Donald Trump complained repeatedly about how the United States tracks the number of people who have died from COVID-19, claiming, "This country and its reporting systems are just not doing it right."

Study identifies new cause of COVID-19 blood clots

Blood clots continue to wreak havoc for patients with severe COVID-19 infection, and a new study explains what may spark them in up to half of patients.

Two studies find age as a primary factor in melanoma treatment resistance

Age may cause identical cancer cells with the same mutations to behave differently. In animal and laboratory models of melanoma cells, age was a primary factor in treatment response.

Study reveals seven “forms of disease” in COVID-19

In a study recently published in the top journal "Allergy", a team of MedUni Vienna scientists led by immunologist Winfried F. Pickl and allergologist Rudolf Valenta (both from the Center for Pathophysiology, Infectiology and Immunology) showed that there are seven "forms of disease" in COVID-19.

UIC enrolls people into phase 3 monoclonal antibody clinical trial

Researchers at the University of Illinois Chicago are now enrolling people into a phase 3 clinical trial that will test if a monoclonal antibody treatment -- administered as a series of four shots -- will help protect uninfected individuals from acquiring or getting sick from COVID-19 after someone in the household tests positive for COVID-19.

Children with multiple islet autoantibodies are more likely to progress to type 1 diabetes

Children with multiple islet autoantibodies - biological markers of autoimmunity -- are more likely to progress to symptomatic type 1 diabetes (T1D) than those who remain positive for a single autoantibody.

Novel approach can help measure antibodies against SARS-CoV-2

A new study lead by Helmholtz Zentrum München indicates a six-fold higher SARS-CoV-2 exposure rate among children in Bavaria, Germany, than reported cases.

Human immune system may play key role in shaping the microbiome composition

The gut is an unusually noisy place, where hundreds of species of bacteria live alongside whatever microbes happen to have hitched a ride in on your lunch.

Seroprevalence and immune response to SARS-CoV-2 in Paris

François Anna et al. published this study in a recent medRxiv* preprint paper, where they present the results of assessing the serological response in the selected population. They tested for specific IgG response against the SARS CoV-2 Nucleoprotein and Spike protein and performed a pseudo-neutralization assay in sera of urban dwellers in Paris.

Booster dose enhances immunogenicity of ChAdOx1 SARS-CoV-2 vaccine in aged mice

Now, a new study published on the pre-print server bioRxiv* shows that a single dose of the vaccine has induced cellular and humoral immunity in aged or older mice. A second dosage was needed to enhance the vaccine's immune response, showing that a prime-boost strategy may be an essential step to boost immunogenicity in the elderly.

COVID-19 study: Researchers recruit frontline workers to identify asymptomatic individuals

Fifteen hundred frontline workers are being recruited for a yearlong study to find what percentage are positive for the virus that causes COVID-19, what percentage become positive and whether the antibodies they produce protect them from reinfection.

Study sheds new light on the biological base of psychotic symptoms

Anti-NMDAR encephalitis is an autoimmune brain illness that is often mistaken by a psychiatric disorder since it causes psychoses and other behaviour alterations. Despite having these similarities, the illness does not respond to common antipsychotic treatments.
