Avoiding detection: How cancers evolve to escape immune system responses
In a study by the Weizmann Institute of Science, researchers pulled out a previously unknown mechanism that allows cancer cells to slip by immune system defenses.

When PSME4 levels are high (left, top and bottom), the tumors grow bigger, cancer-fighting killer T cells (white) are reduced (top) and regulatory T cells (green) that inhibit the immune response are more abundant (bottom), compared with regular(photo credit: WEIZMANN INSTITUTE OF SCIENCE)ByJUDY SIEGEL-ITZKOVICHUpdated:
