Virus Hide and Seek

Since we have all had to think about how viruses evade the immune system sometime in the past 24 hours, here's a tidbit on why the mechanism for latency for Kaposi's Sarcoma-associated Herpes Virus (KSHV) can cause cancer...

An AIDS-related Virus Reveals More Ways To Cause Cancer

Science Daily Researchers at the University of Pennsylvania School of Medicine have shed new light on how Kaposi's Sarcoma-associated Herpes Virus (KSHV) subverts normal cell machinery to cause cancer. A KSHV protein called latency-associated nuclear antigen, LANA for short, helps the virus hide out from the immune system in infected cells. When LANA takes the place of other proteins that control cell growth, it can cause uncontrolled cell replication.
