An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

New study sheds light on why many COVID-19 patients suffer from hypoxia

A new study published in the journal Stem Cell Reports by University of Alberta researchers is shedding light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues.

Novel SARS-CoV-2 variants partially resistant to infection- and vaccine-induced immunity, study finds

A recent study conducted by a team of scientists in the Netherlands has revealed that while severely affected hospitalized COVID-19 patients and vaccinated individuals are capable of neutralizing the B.1.1.7, B.1.351, and P.1 variants of SARS-CoV-2, a significant proportion of non-hospitalized patients with less severe COVID-19 remain susceptible to these viral variants.

New vaccine candidate with RBD and N protein targets protects against SARS-CoV-2 in preclinical trials

A recent study published in the journal Science Advances, explores the immunization of RBD with the P2 epitope of tetanus toxoid, to enhance its immunogenicity, and also tests the benefit of N protein in the vaccine.

How antibody production in the lungs can determine severe respiratory infections

Recent findings describe how the presence of certain antibodies within the lungs can induce an immune response to minimize the effects of these infections.

Scientists test antibody-based therapy to treat Crimean-Congo hemorrhagic fever virus

Army scientists working as part of an international consortium have developed and tested an antibody-based therapy to treat Crimean-Congo hemorrhagic fever virus (CCHFV), which is carried by ticks and kills up to 60 percent of those infected.

Novel antibody engineering approach

Scientists from the Johns Hopkins University School of Medicine, USA, have recently developed an Antibody Display technology by grafting the second extracellular domain of tetraspanin12 (Tspan12EC2) and the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein on the heavy chain complementarity-determining region 3 (CDR3).

Researchers find natural metabolites help SARS-CoV-2 escape antibodies

An international team of scientists has identified a human molecule — biliverdin — as a potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) target. The binding of the heme metabolite to the N-terminal domain of SARS-CoV-2 is associated with the virus’s ability to dodge the immune system by suppressing antibody binding to the spike protein.

NIH launches first-in-human, Phase 1 trial assessing investigational nanoparticle influenza vaccine

A first-in-human, Phase 1 trial assessing the safety and immunogenicity of an investigational nanoparticle influenza vaccine designed to provide long-lasting protection against multiple flu virus strains has begun at the National Institutes of Health Clinical Center in Bethesda, Maryland.

Study confirms poor immunogenicity in hemodialysis patients receiving single dose BNT162b2 vaccine

Researchers from Ontario, Canada, recently conducted a prospective observational study to determine the SARS-CoV-2 antibody response in chronic hemodialysis patients following one vs. two doses of the BNT162b2 COVID-19 vaccine. The results were compared to health care worker controls and convalescent serum.

Scientists explain possible causes of anaphylaxis following mRNA COVID-19 vaccination

New research from a team of scientists at the Centre for Research in Molecular Modeling, Department of Chemistry and Biochemistry, Concordia University in Canada, has aimed to determine the potential causes of anaphylaxis or allergic reactions reported in some individuals after receiving COVID-19 vaccines, including the mRNA vaccines by Pfizer-BioNTech and Moderna.

Moffitt Cancer Center presents new data from dozens of clinical research studies at ASCO

Moffitt Cancer Center, a national leader in cancer care and research and the only National Cancer Institute-designated Comprehensive Cancer Center based in Florida, is presenting new data from dozens of clinical research studies at this year's American Society of Clinical Oncology (ASCO) Annual Meeting, the world's largest clinical cancer research meeting.

Antibody cocktail effectively inhibits SARS-CoV-2 in the rhesus macaque model

Researchers from the US tested the prophylactic potential of a combination of 2 mAbs administered 3 or 75 days before respiratory challenge in rhesus macaques. They used the rhesus macaque model to test the added benefit of combinatory parenteral administration of 2 high-affinity anti-SARS-CoV-2 mAbs - C144-LS and C135-LS. These mAbs were developed to neutralize the virus and tweaked to improve their pharmacokinetics.

Study offers longitudinal roadmap of immune activation and resolution in mild COVID-19

Researchers from the US recently profiled the longitudinal immune response in mild COVID-19 patients starting with early time points of 1-15 days post-infection through convalescence to over 100 days after onset of symptoms.

FDA approves investigational monoclonal antibody therapy sotrovimab for COVID-19

The U.S. Food and Drug Administration (FDA) has given the green light on the investigational monoclonal antibody therapy, sotrovimab, as a coronavirus disease (COVID-19) treatment.

Using Sotrovimab to treat COVID-19 early

A new study published on the medRxiv* preprint server hypothesized that a monoclonal antibody that has the capability to neutralize all sarbecoviruses could also be used to target a highly conserved epitope. This conserved sequence has a high probability of remaining unchanged in SARS-CoV-2 variants.

A novel multiplexed diagnostic approach for COVID-19

Researchers developed a platform for detecting the virus directly from a patient's sample as well as the immune response through antibodies such as IgG and IgM.

Researchers repurpose pre-existing anti-SARS-CoV antibody to develop potent neutralizing antibody against SARS-CoV-2

A team of scientists from the United States has recently engineered a pre-existing anti-severe acute respiratory syndrome coronavirus (SARS-CoV) neutralizing antibody to increase its binding affinity for the spike receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The engineered antibody demonstrates high potency in neutralizing SARS-CoV-2 and preventing infection in animals.

SARS-CoV-2 variants partially escape humoral immunity, but not T cells responses, study finds

Researchers at the Department of Viroscience, Erasmus MC, National Institute for Public Health and the Environment, Amsterdam UMC, and the Weill Medical College of Cornell University studied humoral and cellular immune responses to the wild type SARS-CoV-2, the B.1.1.7 variant (U.K. variant) and the B.1.351 variant (South African variant) in health care workers vaccinated with the BNT162b2 (Pfizer-BioNTech) mRNA vaccine.

Different early antibody responses define COVID-19 disease trajectory

In a new study posted to the bioRxiv* preprint server, a prospective cohort of patients with COVID-19 exhibited distinct features of the IgG fragment antigen-binding (Fab) and fragment crystallizable (Fc) domains, predicting two distinct disease trajectory two days after a positive test.

A novel multi-epitope COVID-19 vaccine developed using reverse vaccinology

A new study has been published in the Journal of Biomolecular Structure and Dynamics which focuses on the evaluation of E, M, N, ORF10, ORF8, ORF3a, and M proteins using bioinformatics tools to develop a multi-epitope COVID-19 vaccine. The researchers utilized in-silico methods to incite humoral and cellular immune responses.
