A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.
Rapid Novor Inc., the world’s leader in mass spectrometry (MS)-based antibody protein sequencing, announced today that its REpAb® antibody discovery platform was used to successfully sequence a complex mixture of functional antibodies directly from the serum of a human patient after receiving a COVID-19 vaccine.
A population of unconventional white blood cells has recently captured the attention of immunologists and clinicians alike.
In this study, the researchers focused on para-nitro-L-phenylalanine (pN-Phe), a non-standard amino acid that is neither one of the twenty standard amino acids nor been observed in nature.
Understanding the ways our immune response changes as we age holds the key to designing better vaccines and boosting protection for people most at risk.
As the northern hemisphere heads into summer, we may be in for a COVID-19 reprieve. Not because the pandemic is over; the Omicron subvariant 'Arcturus' is still creeping upward and causing new symptoms.
Scientists have collaborated to produce the first gene-edited calf with resistance to bovine viral diarrhea virus (BVDV), a virus that costs the U.S. cattle sector billions of dollars annually.
Public health experts discovered an increase in cases of myocarditis, an inflammation of heart muscle, after the introduction of the new COVID-19 vaccinations two years ago, particularly in young males who had received mRNA vaccines.
A team of researchers at Los Alamos National Laboratory recently published the most comprehensive study of global COVID-19 variant transitions, which showed significant diversity in variant spread around the globe related to vaccination rates, number of co-circulating variants and immunity from previous infection.
Results could speed development of new antivirals or vaccines that could counter many different coronavirus variants.
An anonymous San Diego resident has become a fascinating example of how the human immune system fights SARS-CoV-2.
Gut bacteria that break down a sugar called fucose could be dampening our immune response to the COVID-19 mRNA vaccine, according to a study led by researchers from the Okinawa Institute of Science and Technology.
Salmonella infections cause about a million deaths a year worldwide, and there is an urgent need for better vaccines for both typhoid fever and non-typhoidal Salmonella disease.
Researchers at the University of Geneva have developed a novel optical imaging approach that provides a four-dimensional view of cell secretions in real-time, including their spatial and temporal dynamics.
Developing and testing new treatments or vaccines for humans almost always requires animal trials, but these experiments can sometimes take years to complete and can raise ethical concerns about the animals' treatment.
Beyond vaccines, mRNA offers immense potential to fight disease, but targeting the genetic material to specific diseased cells is challenging-; requiring a new method.
The human body is capable of creating a vast, diverse repertoire of antibodies-;the Y-shaped sniffer dogs of the immune system that can find and flag foreign invaders.
A recent study in the Journal of Biological Chemistry revealed the key to a protein that commonly causes blindness.
New research from Washington University School of Medicine in St. Louis suggests that transposable elements in various cancers potentially may be used to harness novel immunotherapies against tumors that don't typically respond to immune-based treatments. Shown is a 3D rendering of cancer cells.
A new study has uncovered the role of B and T cells in controlling tuberculosis (TB) infections.
New research from Oregon Health & Science University and collaborators indicates lab-made antibodies may be able to cure people infected with yellow fever, a virus for which there is no treatment.
