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.

Study reveals the cross-protective role of Omicron infection in vaccinated individuals

A new study compares the cross-protective humoral responses to different SARS-CoV-2 variants induced by vaccination or infection.

Anti-SARS-CoV-2 antibodies persist in breast milk, even after gastrointestinal digestion

Researchers evaluate the persistence of anti-SARS-CoV-2 IgA and IgG in breast milk before and after in vitro gastrointestinal digestion.

Using microfluidics and magnets to isolate rare, allergen-reactive white blood cells

Across the world, food allergies are on the rise. One of the most important cells in studying this ailment are basophils, which activate inflammation and other responses to allergens such as rashes, and sometimes, anaphylaxis.

Study suggests that recall of B cell memory may depend on relative locations of prime and boost immunization

A new study investigated whether a specific population of local Bmem cells in the proximal LNs produce secondary GC responses that are different from those at distal sites and if the location in humoral immunity is relevant only to nonlymphoid tissues.

Study reports SARS-CoV-2 accessory proteins downregulate MHC-I expression using distinct mechanisms

Researchers observed SARS-CoV-2 downregulates the expression of MHC class I molecules.

Study shows a strong negative association between BNT162b2 vaccination-induced S1 IgG concentration and age

Researchers assessed the impact of BNT162b2 coronavirus disease 2019 (COVID-19) vaccination on antibody acquisition.

Tiny shark-derived antibodies broadly neutralize most SARS-CoV-2 variants

Resarchers discuss the ability of shark-derived antibodies to protect against multiple variants of SARS-CoV-2.

23 May 2022

Women who are pregnant or nursing should receive a COVID booster vaccination

In a recent study posted to the medRxiv* preprint server, researchers evaluated the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) booster vaccination in nursing and pregnant women.

23 May 2022

SARS-CoV-2 Omicron subvariants are increasingly escaping immunity

In a recent study posted to the medRxiv* preprint server, researchers evaluated the neutralization evasion of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron sublineages.

Deep visual proteomics is redefining cancer diagnostics

In a recent study published in the journal Nature Biotechnology, researchers introduced deep visual proteomics (DVP), an amalgamation of artificial intelligence (AI) for image analysis and mass spectrometry (MS) for proteomic profiling of biological samples.

Anti-SARS-CoV-2 titers predict COVID severity

A recent study published in the journal Viruses reported that antibody titers against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) could serve as a marker for the severity of coronavirus disease 2019 (COVID-19).

Research provides new insight into how Crimean-Congo hemorrhagic fever virus causes disease

Army scientists determined that the body's own natural immune response contributes to disease severity in mice infected with Crimean-Congo hemorrhagic fever virus (CCHFV), which causes a widespread tick-borne viral infection in humans.

20 May 2022

Serologic response to SARS-CoV-2 may predict COVID-19 severity

A new study reported that antibody titers against SARS-CoV-2 could serve as a marker for the severity of COVID-19.

20 May 2022

Exploring cross-neutralizing anti-SARS-CoV-2 antibody responses among the general population

Researchers performed a molecular analysis of cross-reactive antibodies targeted against the receptor-binding domain of SARS-CoV-2 strains among the general population.

20 May 2022

Studies provide insight into how long COVID-19 immunity lasts and nature of immune recall

How does the immune system remember and recognize viral invaders it has encountered in the past? A trio of newly published studies of people infected with SARS-CoV-2, vaccinated against the virus or both, are providing tantalizing new clues about the factors that influence the speed and magnitude of the immune system's response to subsequent infection with variants of SARS-CoV-2.
