Adenoviruses, which can cause colds, gasteroenteritis, and conjuctivitis — or pinkeye — can be genetically modified to infect cancer cells without affecting healthy cells.
The engineered virus works several ways. It kills cancer cells directly, it delivers therapeutic genes to cancer cells, and it promotes immune responses against tumor cells expressing a certain protein.
But a major pitfall of this approach is that the immune system sees the virus as an invader, so most T-cells go after the virus instead of cancer proteins. When the virus does manage to infect cancer cells, the T-cells fight only those cancer cells the virus has reached, leaving the remaining cancer cells unharmed.
