Antibodies play an important role in the immune system. The immunoglobulins present on the B-lymphocyte surface send in signals to the cytoplasmic and nuclear electors. These also deliver the antigen ...

Beyond direct neutralization, antibodies induce, through their crystallizable fragment (Fc) domain, innate and adaptive immune responses critical to a successful host immune response against infection ...

A study led by investigators from the Ragon Institute of MGH, MIT and Harvard finds evidence that antibody protection may help control infection with the bacteria that causes tuberculosis (TB). In ...

In a recent study published in Science Translational Medicine, researchers evaluated the differential humoral immune response to two coronavirus disease 2019 (COVID-19) vaccines - messenger ...

Effective antibody responses against HIV are rare both during natural infection and after vaccination. As a result, many research groups have focused their efforts on identifying and characterizing ...

Antibodies—proteins that are produced by our immune system to protect us—are crucial for recognizing and getting rid of unwanted substances, or antigens, in our body. Although their role is universal, ...

Researchers have discovered a new function of anti-HIV-1 antibodies by applying cutting-edge microscopy techniques to in vitro viral cultures. The scientists found that certain antibodies already ...

Monoclonal antibodies have proved effective in the prevention and treatment of Covid-19. Their effectiveness depends on the recognition of specific structures on the surface of the viral spike protein ...

Thyroid antibodies are cells the immune system forms in response to thyroid cells. They develop when the immune system mistakenly attacks thyroid cells and tissues. High levels can indicate an ...

Researchers have analyzed the antibody Immunoglobulin M in rainbow trout to shed some light on why these proteins may have evolved over time. Antibodies -- proteins that are produced by our immune ...
