The medical use of proteins has a long history. It started more than one century ago when immune sera of animal origin were introduced for the prevention or treatment of infections, followed by the use of insulin of porcine and bovine origin some decades later. These products were immunogenic in patients, sometimes even leading to serious anaphylactic reactions. These side effects were easily explained by the foreign nature of the proteins leading to a classic immune reaction.
The introduction of human-derived proteins, such as growth hormone and factor VIII, also was associated with the induction of antibodies. However, these products were mostly given to children with an innate deficiency and therefore a lack of immune tolerance.
With the development of recombinant DNA technology, the large-scale production of human homologues like the interferons (IFNs), growth factors, and hormones became feasible, resulting in the application for a large number of patients. It was a surprise that these products also induced antibodies, which cannot be explained by the lack of immune tolerance. Some of the potential mechanisms involved in the production of antibodies to recombinant …
