Molecular mimicry

  • abstract: Molecular mimicry is defined as the theoretical possibility that sequence similarities between foreign and self-peptides are sufficient to result in the cross-activation of autoreactive T or B cells by pathogen-derived peptides. Despite the promiscuity of several peptide sequences which can be both foreign and self in nature, a single antibody or TCR (T cell receptor) can be activated by even a few crucial residues which stresses the importance of structural homology in the theory of molecular mimicry.

  • Two common gut bacteria, Escherichia coli and Helicobacter pylori, and also the influenza-A virus, are particularly adept at playing the evasive game of molecular mimicry, and the team is now looking at possible connections between different gut bacteria and autoantibodies against melanocortins to see if they can pin down which, if any, of these bugs might be responsible.
