Question

antigenicity & immugenicity note

Answer 1

.Immunogenicity – is the ability to induce humoral and /or cell mediated immune response. We know when B and T cells get activated by antigen, it results in effector cells and memory cells. For example, if B cell gets activated, it will differentiate into plasma B cell which secrets antibodies.



.Antigenicity – is the ability to combine with the final products of the humoral and/or cell mediated immune response. It is not activating the immune response rather it combines with the final products of the immune response. For example, as we just saw when B cells get activated it secrets antibodies and the antigens which have the property of antigenicity will combine to these antibodies.
