About Story Of Interferon, The: The Ups And Downs In The
From The New England Journal of Medicine Interferons have proved therapeutically effective for the control and sometimes cure of viral infections, cancer, chronic infections in immunodeficiency, and multiple sclerosis. Because they were the first previously unavailable proteins with clinical and economic importance to be produced by recombinant DNA technology, interferons contributed critically to the growth of the biotechnology industry. On the molecular and cellular levels, interferons, as an exemplary group of cytokines, have had a critical role in defining signal-transduction pathways, modulation of gene expression, and promiscuity of cellular actions of cytokines. The Story of Interferon, written by one of the principals in the clinical evolution of interferons, is a reassuring example that perseverance can bring an important scientific observation to clinical application. During the more than 30 years from the discovery of interferons to their production by biotechnology, many scientists and clinicians believed in the clinical potential of these cytokines on the basis of preclinical data. Among the most important of them was a Finnish scientist, Kari Cantell, who dedicated his career to making interferons a clinical success. His goal was to produce enough interferons from leukocytes in donated blood to treat patients. Cantell, whose articles have reached the heights of "Citation Classics," writes in this book about his professional passion, his loves, and his life. Although it is unclear whether this book is intended for a lay or professional audience, Cantell describes the satisfactions, frustrations, and luck that are all part of laboratory science. For young scientists, there are the lessons of focus, dedication, and continued hard work ("Our honeymoon was limited to the sleeper train journey from Oulu to Helsinki, for I was also wedded to my work"). "Me too" science and short-term goals usually result in few important advances ("It is probably difficult for a layman to appreciate how easily scientists are attracted to follow whichever are the currently fashionable trends in their field"). Implicit in the account is the importance of enlightened administrators in supporting creative and dedicated scientists who are working on an important problem ("Most scientists were openly critical in their attitude, or even disparaging.... [The director] did not hesitate for a moment and gave my interferon studies his full support, showing in this way his attitude towards long-term research activities"). There is no better example of the importance of the protected environment provided by federally funded medical-research institutes for the undertaking of major investigations requiring long-term commitment. Cantell worked in an era when international science was maturing from bud to flower. His accounts of important international contributions to the knowledge of interferons illustrate the critical role of the modern international community of scientists. Cantell devoted his career to the production of clinically useful quantities of pure proteins that are produced by most vertebrate cells in only picogram amounts. When the biotechnology link was made by Charles Weissmann in Switzerland, not only did effective techniques for production evolve, but also the entire family of proteins that constitute the interferons produced by leukocytes was unexpectedly discovered. Working with Weissmann, Cantell was also introduced to the competitiveness that can be part of cutting-edge science ("As a result of these items of news and rumors, the pace of work in Weissmann's laboratory accelerated.... When I made my next visit to Charles, I noticed a sleeping bag in his office, and that told me a lot"). Without Cantell's dedication, the clinical benefits of interferons probably would not have been realized for several more years. But all forms of technology advance with the rapidity with which computer hardware changes, and likewise the tech
