New ‘atlas’ charts how antibodies attack spike protein variants

Scienmag

Antibodies capable of neutralizing multiple SARS-CoV-2 strains can inform strategies for broadly protective COVID-19 booster vaccines As the SARS-CoV-2 virus that causes COVID-19 continues to evolve, immunologists and infectious diseases experts are eager to know whether new variants are resistant to the human antibodies that recognized initial versions (..)

Scientists unmask new neutralizing antibody target on SARS-CoV-2 spike protein

Scienmag

SARS-CoV-2 can recruit a haem metabolite to evade antibody immunity Researchers have identified another potential target for neutralizing antibodies on the SARS-CoV-2 Spike protein that is masked by metabolites in the blood.

8 Of The Most Common Foods Allergies – Do You Have One?

Delveinsight

As per the Food Allergy Research & Education, in the US, each year, around 200,000 people require emergency medical care for allergic reactions to food. Food allergy is a specific immune response to certain food items that it considers harmful. The symptoms of food allergy vary from person to person and can also differ over time.

ZyCoV-D is designed to introduce DNA that encodes for a viral protein into human cells. By ordering human cells to make the protein, ZyCoV-D could cause an immune response against the coronavirus. In a new study that is published in Science, the team displayed that one soluble receptor protein, sACE2.v2.4,

HIV vaccines suffer setbacks but new approaches could turn the tide

Pharmaceutical Technology

Additionally, advances in the study of broadly neutralising antibodies (bNAbs) have led to new candidates being studied in early trials. mRNA vaccines can be made and modified quickly compared to protein subunit vaccines, says Montefiore. This response was also seen in the RV 144 trial, she notes.
