Antibody News and Research

RSS

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 method can detect high levels of COVID-19 antibodies

A more efficient and much faster method to assess high levels of neutralizing antibodies to COVID-19 could point the way to better understanding and treatment of the disease, according to new published findings by scientists from the Hackensack Meridian Center for Discovery and Innovation (CDI) and the University of Michigan (U-M).

Seropositivity to SARS-CoV-2 among asymptomatic blood donors in New York

New York was the hardest-hit U.S. state during the peak of the outbreak in the country. Now, a team of researchers from the New York Blood Center and Serimmune, an immune intelligence company, aimed to determine the prevalence of seropositive people for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, among healthy blood donors.

DNA vaccine-induced antibodies neutralize SARS-CoV-2

The coronavirus disease (COVID-19) is far from over as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to ravage across the globe. With the vast spread of the virus, many countries who reported flattening the curve over the past months have reported clusters of new cases and second waves of the outbreak.

COVID-19 patient's immune response may underlie the effects on the nervous system

It is probably the immune response to, rather than the virus in itself, that causes sudden confusion and other symptoms from the nervous system in some patients with COVID-19. This is shown by a study of cases involving six Swedish patients, now published in the journal Neurology.

Researchers use molecular dynamics simulations to identify secrets of SARS-CoV-2 virus

The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells to contribute its machinery to assist in its propagation.

"Immunological imprinting" could influence antibody response to COVID-19

Researchers in the United States and Spain have shown that prior exposure to seasonal coronaviruses may influence antibody responses to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative agent of coronavirus disease 2019 (COVID-19).

Spike protein of SARS-CoV-2 virus identifies and binds neuropilin-1 on human cells to infect them

Helping to explain what makes SARS-CoV-2 so capable of infecting human cells, researchers in two independent studies discovered that the virus's spike protein recognizes and binds a protein on the human cell surface called neuropilin-1.

3D imaging of SARS-CoV-2 infection in ferrets using light sheet microscopy

Researchers from the Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health demonstrate the ability to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in 3D tissue samples in ferrets. This will allow the detection of infection patterns in tissues and their interrelations.

Scientists are developing a point-of-care SARS-CoV-2 detection system based on photonic sensors

Detecting SARS-CoV-2 virus and related antibodies is essential to control the COVID-19 pandemic. A multidisciplinary team of scientists from the University of Malaga, led by Robert Halir, researcher of the Department of Communications Engineering of the Higher Technical School of Telecommunications Engineering, aware of the limitations of current techniques, are developing a point-of-care detection system based on photonic sensors.
