IgG antibodies activate blood platelets and contribute to the severity of anaphylaxis

The most severe allergic reaction, anaphylaxis (or anaphylactic shock), is the result of an inappropriate immune reaction following the introduction of a usually harmless antigen into the body. The production of antibodies against this antigen (or allergen) allows the formation of antibody-antigen complexes that trigger a massive secretion of potent mediators, resulting in organ failure,

Researchers study ‘universal’ protective human antibodies

Scientists from the German Cancer Research Center (DKFZ) have been studying how the immune system succeeds in keeping pathogens in check. For the first time, the researchers have now discovered antibodies that are capable of disarming not only one specific bacterium, but a whole variety of microorganisms at once. The newly discovered antibodies recognize a
