Immunologists reflect on fifty years since interleukin-2 discovery and its lasting impact
Rafi Ahmed and Steven Rosenberg published a perspective marking the fiftieth anniversary of the interleukin-2 discovery in September.
Discovery timeline and legacy debate
Colleagues published a paper describing interleukin-2 fifty years ago. Some experts say this protein enabled the growth of human T cells for cancer treatment. Others believe it allowed researchers to find the first human retroviruses.
Scientific process and unexpected results
Basic science often leads to outcomes that researchers cannot predict at the start. Supporters of funding note that many major medical advances began with such work. Critics sometimes expect immediate results from scientific projects instead of long-term benefits.
