Jean Francois Borel Belgian Microbiologist Scientist Hand Signed Photo & Letter

CHAU1650  A vintage original 6" x 4" personally autographed photo and accompanying hand signed letter on the original headed paper of Jean Francois Borel who is a Belgian microbiologist and immunologist for the discovery of cyclosporin. - For the main gallery image I have laid both items together partially covering the letter but you can view the other images to view the full letter fully written in hand and signed 7th January 1987 - bar the letter centrally folded (which is how I will post) both items are otherwise truly outstanding condition with the photograph having the signing undedicated with the signature resting perfectly besides his portrait and with further notation on the reverse - Surely the ultimate Jean Francois Borel autograph opportunity of its kind.

In 1972, Borel was involved in the discovery of the immunosuppressive effects of cyclosporin (Sandoz called Sandimmun), which was isolated by Sandoz in 1971 from a fungus that a Sandoz employee brought back from vacation in Norway. The screening program at Sandoz was previously developed by K. Saameli (and Stähelin) and the immunological testing procedures of S. Lazary. Initially, use as an antibiotic was considered. When it was realized that the substance had only Tcells and therefore had potential in transplantation medicine, Borel aroused much attention in 1976 at a congress in London. In the practice of organ transplantation, the new drug was tested in 1977 by the British surgeon Roy Yorke Calne. In 1983, Borel became vice president of the pharmaceutical division of Sandoz (later Novartis). Since 1981 he was Professor of Immunopharmacology at the University of Bern.
