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.

Mix and match COVID-19 vaccines safe and effective: German study

A new preprint study posted to the medRxiv* server shows an AstraZeneca’s ChAdOx1-nCov-19 and Pfizer/BioNTech BNT162b2 COVID-19 vaccine combination is immunologically superior to two AstraZeneca ChAdOx1-nCov-19 doses.

Potent antibody responses to BNT162b2 COVID-19 vaccine among Japanese healthcare workers

In a paper recently uploaded to the preprint server medRxiv* by Nakajima et al. (June 4th, 2021), the antibody responses of over 2,000 Japanese healthcare workers were tracked over a period of several months, with particular regard to serum Immunoglobulin G (IgG) against the SARS-CoV-2 spike protein.

Cell-to-cell contact helps in spreading SARS-CoV-2, finds study

People aren’t the only ones who should be social distancing — new research shows our cells need to as well. Researchers from Ohio State University in Columbus, Ohio, USA, used in-culture techniques to confirm SARS-CoV-2 transmission via cell-to-cell contact.

What is the role of monoclonal antibody therapy in treating COVID-19?

A new study has been published in the journal Vaccines that deals with the present state of research on using mAbs for the treatment of the COVID-19 disease. Many clinical trials are being conducted to evaluate the efficacy and safety of several newly designed mAbs. Some of the mAbs are directed towards immune system responses, i.e., non-SARS-CoV-2 specific mAbs, while others are devised to neutralize the SARS-CoV-2 protein structure, i.e., SARS-CoV-2 specific mAbs.

Brain study may lead to new treatments for neuro-immune conditions

The immune system is the brain's best frenemy. It protects the brain from infection and helps injured tissues heal, but it also causes autoimmune diseases and creates inflammation that drives neurodegeneration.

FDA approves monoclonal antibody aducanumab for treating Alzheimer's patients

Today's FDA approval of the monoclonal antibody Aduhelm (aducanumab) to treat patients with Alzheimer's disease reflects years of significant advances in Alzheimer's research. This is the first new Alzheimer's drug approved in 17 years and the first shown to modify the course of the disease, which FDA believes will lead to slowing of patients' cognitive decline.

Scientists explain why space travel weakens the human immune system

Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their mission.

Reduced use of convalescent plasma associated with higher COVID-19 mortality rate

A new study from researchers at Johns Hopkins Bloomberg School of Public Health and colleagues suggests a slowdown in the use of convalescent plasma to treat hospitalized COVID-19 patients led to a higher COVID-19 mortality during a critical period during this past winter's surge.
