Study shows strong protective effect of IgG3 antibodies in SARS-CoV-2 infection

Researchers published a study on the expression and functional analyses of a neutralizing mAb with identical variable domains but different constant HCs, representing IgG1-4.

SARS-CoV-2 emerging variants display enhanced syncytia formation

Researchers compared the replication and syncytia forming potential of Alpha, Beta, and D614G strains in human cell lines and primary airway cells.

Study shows lower SARS-CoV-2 infection rates in smokers

Coronavirus disease 2019 (COVID-19) primarily infects the lungs, later spreading through the bloodstream. The worst prognoses are mostly seen in ‘at-risk’ groups, such as the immunocompromised, elderly, or those suffering from respiratory conditions.

Plasmid DNA vaccines induce effective antibody responses against SARS-CoV-2 in mice

Researchers in the United States and China have developed plasmid DNA immunogens that induce effective antibody responses in mice against the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

AstraZeneca COVID-19 vaccine safe and effective in phase 3 U.S., Chile, and Peru trial

A new study reports on the results of phase III clinical trial on the safety and efficacy of the AstraZeneca-Oxford COVID-19 vaccine.

A possible protective genetic polymorphism in COVID-19

A new study discusses the role of a mucin gene enhancer on the clinical phenotype of the COVID-19.

Anti-nucleocapsid SARS-Cov-2 antibodies wane over time in long-term care facilities

A new study shows that up to a third of survivors in LTCFs were infected during the first year after infection.

SARS-CoV-2 beta variant elicits variant specific and cross-reactive antibodies

One recent study assessed the serum of Beta variant infected patients to determine whether major non-VOC antibodies could neutralize this virus.

Anti-CD20 therapy patients can develop immune responses after SARS-CoV-2 vaccination

A new systematic review and meta-analysis focused on the humoral and cell-mediated immune responses after COVID-19 vaccination in patients undergoing anti-CD20 antibodies treatment.

CAR-T cells require an abundance of antigens to efficiently kill solid tumors

Immunotherapy, which harnesses the power of the body's immune system to fight disease, is gaining huge traction in treating cancer.

Humoral responses to SARS-CoV-2 are detectable through saliva, scientists find

Your saliva may be able to tell you if you’ve developed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies, suggests a new medRxiv* preprint study. In immunocompromised groups, salivary Immunoglobulin G (IgG) antibody levels were associated with IgG titers in blood serum 3 to 4 weeks after mRNA vaccination.

SARS-CoV-2 mRNA vaccines elicit higher levels of antibodies compared to natural infection

Researchers from the US recently characterized the scale and specificity of SARS-CoV-2 spike-reactive antibodies from 23 participants who received SARS-CoV-2 mRNA vaccines and 10 acutely infected health care workers. They found that primary mRNA vaccination and infection elicited S1- and S2-reactive antibodies, while secondary mRNA vaccination elicited mostly S1 antibodies.

Scientists analyze if T-cell tests can be used to determine whether people had COVID-19

Can T-cell tests be used to determine whether people have had COVID-19? Scientists at Uppsala University and Karolinska Institutet have jointly analysed this issue under the aegis of the COMMUNITY study at Danderyd Hospital. Their study is published in the scientific journal PLOS ONE.
