A fraction of antibodies present in all healthy individuals begins to recognize large number of self-antigens only after a transient exposure to certain protein-destabilizing conditions, including low or high pH, high salt concentration, chaotropic factors and redox-active agents. Recent findings on the molecular mechanisms of the inducible antibody auto-reactivity, obtained by using kinetic and thermodynamic analysis on the interactions of single monoclonal antibody with its cognate antigen are discussed in the review.
