Work

George Snell shared the 1980 Nobel Prize in Physiology or Medicine with Baruj Benacerraf and Jean Dausset for their discoveries concerning "genetically determined structures on the cell surface that regulate immunological reactions". Snell specifically "discovered the genetic factors that determine the possibilities of transplanting tissue from one individual to another. It was Snell who introduced the concept of H antigens." Snell's work in mice led to the discovery of HLA, the major histocompatibility complex, in humans (and all vertebrates) that is analogous to the H-2 complex in mice. Recognition of these key genes was prerequisite to successful tissue and organ transplantation.

Famous quotes containing the word work:

    “Human life itself may be almost pure chaos, but the work of the artist—the only thing he’s good for—is to take these handfuls of confusion and disparate things, things that seem to be irreconcilable, and put them together in a frame to give them some kind of shape and meaning. Even if it’s only his view of a meaning. That’s what he’s for—to give his view of life.”
    —Katherine Anne Porter (1890–1980)

    “The literary critic, or the critic of any other specific form of artistic expression, may detach himself from the world for as long as the work of art he is contemplating appears to do the same.”
    —Clive James (b. 1939)

    “Our kids will develop a work ethic only if we require them to pay a portion of the cost of some of the things they want. They’ll learn to defer gratification the moment we stop routinely pulling out our wallets. And they’ll learn self-discipline only if we care enough to enforce reasonable limits.”
    —Fred G. Gosman (20th century)
