The WHO Technical Advisory Group on COVID-19 Vaccine Composition (TAG-CO-VAC) continues to closely monitor the genetic and ...

Not just IgG4 antibodies that become predominant in the many-jabbed, but also lesser studied IgG2, researchers find. NIH ...

Neutralization test is one tool used for serodiagnosis ... using the nucleocapsid-recombinant protein of Araraquara virus (ARAV) as antigen, allows to detect, in 10–15 min, antihantavirus ...

Antibodies are produced by plasma cells and protect the host from infection in three main ways: by binding to pathogens to inhibit their toxic effects or infectivity (neutralization), by coating ...

A new study provides fresh insight into traditional acid-base chemistry by revealing that the mutual neutralization of isolated hydronium (H 3 O⁺) and hydroxide (OH⁻) ions is driven by ...

They need to hunt for clues. One way they can do that is with a carcinoembryonic antigen test. It measures a protein called CEA in the blood. People with some types of cancers have higher than ...

The body stores white blood cells in different places, known as lymphoid organs. An antigen is any substance that can spark an immune response. In many cases, an antigen is a bacterium ...

Two types of COVID-19 tests, the rapid antigen test and the polymerase chain reaction (PCR) test, are available in the United States. The PCR typically relies on lab testing and is still considered ...

Traditionally, T cell responses are measured based on their cytokine production upon peptides or whole antigen stimulation by intracellular cytokine staining. However, this method is often not ...

Innate lymphoid cells (ILCs) resemble lymphocytes, but lack the key characteristics of adaptive immune cells, namely an antigen-specific receptor. ILCs interact closely with IECs and fulfil an ...
