Researchers Discover How Cancer Evades the Immune System

A study on various kinds of cancer, conducted by researchers at the University of Southern California, has brought about the discovery of a new method to identify the genetic changes that enable tumours to evade the body's immune system. The findings, demonstrated in human breast and colo...

Herpes Infects Cornea, Evades Immune Cells

Research Indicates Geron's Human Embryonic Stem Cell-Based Therapeutic for Spinal Cord Injury Evades Direct Attack by the Human Immune System

MENLO PARK, Calif.--(BUSINESS WIRE)--Jun 11, 2007 - Geron Corporation (Nasdaq:GERN) today announced the presentation of research studies indicating that GRNOPC1, the company's human embryonic stem cell (hESC)-based therapeutic for the treatment of spinal cord injury, evades a direct attack by the h...

Researchers Discover Method for Identifying How Cancer Evades the Immune System
