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.

mAb treatment can rapidly select for SARS-CoV-2 resistance, suggests study

A study evaluates the efficacy of a mAb to prevent disease progression in non-hospitalized persons with symptomatic SARS-CoV-2 infection.

Adenovirus-based nanoparticle vaccine elicits potent SARS-CoV-2 neutralizing antibody response

In a study available on the preprint server medRxiv*, researchers have created a vaccine designed to overcome issues associated with attenuated-virus vaccines.

Multiple sclerosis patients elicit robust T-cell responses to mRNA COVID-19 vaccines

New research shows that Multiple Sclerosis (MS) patients undergoing anti-CD20 (aCD20) treatment – which depletes the B cells that contribute to the MS attacks – are able to mount robust T-cell responses to the mRNA COVID-19 vaccines, despite having a muted antibody response to the vaccines.

Study points to a possible new approach for treating MRSA superbug

A study released in STEM CELLS Translational Medicine, by researchers at the Baker Institute for Animal Health, part of Cornell University's College of Veterinary Medicine, Ithaca, N.Y., details in a relevant ex vivo model how treating wounds with the secretion of a type of stem cell called mesenchymal stromal cell (MSC) effectively reduced methicillin-resistant Staphylococcus aureus – better known as MRSA viability and stimulated the surrounding skin cells to build up a defense against the bacterial invader.

Fatal COVID-19 infections linked to poor immune responses and elevated MAIT cell activation

The mortality rate of COVID-19 patients requiring mechanical ventilation is 30-40%, however, the immunological factors associated with death in critically ill COVID-19 patients are poorly understood.

Pfizer vaccine induces strong immunity in elderly with prior COVID-19

A new study discusses the vaccination response in elderly who were vaccinated with one dose of the Pfizer vaccine 15 months after contracting COVID-19.

Antiviral compound RG10 acts via intracellular SARS-CoV-2-ER dynamics

A new study describes a small molecule referred to as RG10 that may have potent antiviral activity against SARS-CoV-2 in human cells.

Live oral SARS-CoV-2 vaccine provides partial protection in Rhesus Macaques

A new study describes the partial protection against respiratory infection with SARS-CoV-2 following gut inoculation with a live attenuated virus.

How Fauci and the NIH got ahead of the FDA and CDC in backing boosters

In January — long before the first jabs of covid-19 vaccine were even available to most Americans — scientists working under Dr. Anthony Fauci at the National Institute of Allergy and Infectious Diseases were already thinking about potential booster shots.

Therapeutic potential of clinical-grade ACE2 for blocking SARS-CoV-2 variants

According to new research by an international team of scientists, all SARS-CoV-2 variants, including variants of concern (VOC) Alpha, Beta, Gamma, and Delta, exhibit enhanced affinity toward recombinant human soluble ACE2.

Study looks at exposure to different SARS-CoV-2 variants and immune response

Researchers compared the responses against several SARS-CoV-2 VoCs in sera from individuals exposed to variant infection, vaccination, or both.

COVID mRNA vaccines display weakened immune response with age and diminish over time, according to new study

Researchers from Simon Fraser University in Canada decided to investigate the magnitude of immunity in mRNA vaccines for COVID-19.

Single protein is a key player in two very common forms of dementia, study reveals

Dementia has many faces, and because of the wide range of ways in which it can develop and affect patients, it can be very challenging to treat.

Study on B lymphocytes may contribute to the optimization of vaccines

Our bodies can fine-tune the immune response to an infection and make it proportional to the threat at hand.

SARS-CoV-2 variants show substantial differences in spike structure

To investigate the impact of these mutations, researchers performed cryo-electron microscopy analysis on the variants spike proteins to determine any structural changes.

Natural SARS-CoV-2 infection induces more durable immunity than vaccination study suggests

Scientists from the USA have demonstrated that immunity induced by mRNA-based COVID-19 vaccines in previously SARS-CoV-2-infected people has the highest robustness and durability with cross-reactivity against different viral variants.

Deep profiling of SARS-CoV-2 immune response amongst the mildly symptomatic

In a research paper recently uploaded to the medRxiv* preprint server by Capelle et al. (September 2nd, 2021), the immune response of mild and hospitalized COVID-19 patients is compared, finding that early T-cell response is a vital indicator of SARS-CoV-2 disease severity.

Quantification of salivary IgG and IgA against SARS-CoV-2

Salivary antibody levels are many fold lower than found in blood serum, Immunoglobulin G (IgG) in the saliva is mainly sourced from leakage from the gingival surface and Immunoglobulin A (IgA) from mucosal membranes.
