Cancer: Negative feedback for B cells
Louis M. Staudt1
Abstract
The discovery of a protein that regulates the production of antibody-generating B cells has implications for our understanding of how cancers of the immune system develop — and how they might be treated.
Some 40 years ago, Jacques Monod and François Jacob1 described the role of double-negative regulatory circuits in biological systems. In their example, two enzyme pathways each yield an end-product that inhibits the activity of the other pathway (Fig. 1a
