[Catalytically active antibodies (abzymes) in human milk].

The review is focused on the analysis of published data and the results obtained by the authors about the catalytic activity of antibodies (abzymes) of human colostrum and milk. Possible mechanisms of origination of these abzymes and their potential role in the regulation of biological activity of human milk compounds are considered. A hypothesis about the role of secretoty abzymes in non-specific humoral defense for the epithelial cells against viral infections is proposed.
