Explanation:
Detailed explanation-1: -Molecular mimicry is the term used to describe immunological cross-reactivity between host and bacterial antigens. Immunological cross-reactions between streptococcal and host molecules have been identified by antibodies or T cells that react with streptococcal components and tissue antigens (6, 7, 22, 24, 25).
Detailed explanation-2: -Molecular or antigenic mimicry is a term for the similarity of different antigens, which can be confused by the immune system. Antigen recognition by antibodies and T cell receptors is specific, but not restricted to a single antigen.
