Nobel laureate Jules Hoffmann, whose father helped foster his study of bugs, said his decades of research into the immunity of insects could enable scientists to find a cure for human disorders.
The Luxembourg-born French national was awarded the Nobel Prize for medicine on Monday along with fellow scientists American Bruce Beutler and Canadian Ralph Steinman, who died days earlier of pancreatic cancer.
The trio were hailed for work that "opened up new avenues for the development of prevention and therapy against infections, cancer and inflammatory diseases," said the Nobel Foundation in Stockholm.
"I started working with insects at the age of 17 with my father," Hoffmann, 70, told AFP in the Chinese city of Shanghai, where he is visiting.
"It has been a long, long exciting story with ups and downs. It wasn't a straightforward story but it went -- in the end -- well."
Hoffmann said he last heard from Steinman six months ago and only learned of his death after the Nobel was awarded.
"It's too bad. We didn't directly collaborate in publishing papers. But intellectually we were close," Hoffmann said.
He described Beutler as a friend and long-time colleague with whom he had shared research findings.
Hoffmann's own work has focused on the immune system of insects.
After studying biology, he took a lab position with the French National Research Agency where he began looking at the antimicrobial defences in grasshoppers.
