Dendritic cells stimulate cancer-cell growth

Since their discovery at Rockefeller University some 30 years ago, dendritic cells have been recognized as key players on the immune-system team, presenting antigens to other immune cells to help them respond to novel insults. Now, Rockefeller scientists have shown that dendritic cells also have other, non-immune actions, and may in fact directly modify the biology of some types of cancer cells.
