Therapeutic Antibodies

Therapeutic Antibodies Synopsis

Over 2000 years ago in China, antibodies elicited by early forms of vaccination likely played a major role in the protection of the population from infectious agents. Vac- nation has been further developed in Europe and described by Edward Jenner in the late-eighteenth century, then successfully implemented worldwide. The idea to use theactiveingredientinthebloodofvaccinated(orimmunized)animalsorhumansfor the treatment of diseases came a century later. It was made possible by a series of discoveries,suchastherealizationthattheserumfromanimalsimmunizedwithtoxins, for example, diphtheria toxin or viruses, is an effective therapeutic against the disease causedbythesameagentinhumans.

The first Nobel Prize in Medicine (1901) was given to him for the discovery of the serum therapy.

The revenues from the top-five therapeutic antibodies reached $11. 7 billion in 2006, and major pharmaceutical companies raced to acquire antibody biotech companies with a recent example of MedImmune, Inc. , which was acquired for $15. 6 billion by AstraZeneca in 2007. This explosion of research and development in the field of therapeutic antibodies prompted the publication of the MiMB volume Therapeutic Antibodies: Methods and Protocols. The book's major goal is to present a set of protocols useful for researchers discoveringanddevelopingtherapeuticantibodies. Currentadvancesandfuturetrends in the antibody therapeutics are analyzed in thelead-in review article.
