Antibodies are specifically created and released in response to an invasion from harmful pathogens like bacteria and viruses. As this process repeats itself, the immune response becomes more efficient at producing pathogen-specific antibodies, thus making it easier for the body to fight infections. ...
Second, having found that male-biased genes evolve more rapidly than female-biased genes, we asked whether selective forces resulting from host–parasite interactions could influence this sex-specific evolution. Third, we investigated whether the rapid evolution of male-biased genes is due ...
Unlike your innate immune system, your adaptive immune system does not produce an immediate immune response the first time it sees a pathogen. Instead, it memorizes specific antigens (substances on the surface of pathogens) so that it can attack them when they come on the scene again.6 Your ...
Molecular mimicry in T cell-mediated autoimmunity: viral peptides activate human T cell clones specific for myelin basic protein. Structural similarity between viral T cell epitopes and self-peptides could lead to the induction of an autoaggressive T cell response. Based on the struct... WW Kai...
Allergy responses in the human body are primarily mediated by a specific type of antibody known as immunoglobulin E (IgE). These antibodies have a unique role in the immune system, specifically targeting allergens. They attach to mast cells, which are found in tissues throughout the body. When...

Our first line of defenders is antibodies, some of which are trained to recognize specific pieces of the virus and prevent it from infecting cells. If mutations change those components — akin to putting on a fake mustache and sunglasses — then perhaps the antibodies geared to identify the vir...
Some white blood cells, the early responders, are sent to work out what is going on and to report back so that other appropriate immune system components can be sent, as well as signalling for the development of antibodies specific to the pathogen. Inflammation is a good thing. ...
That may suggest that that ipsilateral vaccination is more likely to provide better protection should the vaccinated person become infected with the SARS-CoV-2 virus."The number of antibodies, however, was not greater," says Martina Sester. Unlike the killer cells, the antibodies do not ...
A 'footprint' of immune responses is established during the first exposure to a pathogen. These specific memory T cell populations are preferentially re-expanded when re-exposed to the same antigen or one that is similar, thereby limiting the clonal expansion of new antigen-specific T cells. A...
