| | B lymphocytes are one member of the body's immune system, an integrated network of cells, each with its own unique tasks within the system, that attack disease-causing viruses, bacteria, and other pathogens. | | | But, as often happens in science, even the most straightforward discoveries turn out not to be so straightforward. | | | But, in the late 1990s, Stetler-Stevenson and colleagues eventually began to question this assumption based on their studies of TIMP-1, an inhibitory enzyme that has also been shown to signal immune cells to grow. |
