Respuesta :
Initiating an immune response against the antigen, such as antibody formation, cytotoxic cell activation, or both, is stimulated by the lymphocytes' receptors binding to the antigens' surface molecules.
How does the body react to antigens after a viral invasion?
The body will store knowledge about the germ and how to resist it if it comes into touch with an antigen for the first time. B-cells will create antibodies if an antigen enters the body and they are able to identify it (either by prior exposure to the disease or through vaccination against it).
What happens when an antigen is initially exposed?
Effectors are produced by an organism when it comes into contact with a certain antigen for the first time. T and B cells, which have been activated, fight off the pathogen. A primary immune response is defined as the development of these effector cells as a result of the initial exposure.
