Salmonella flags cancer to the immune system when injected into tumours, scientists find

LNM Radio Network

The food poisoning bug salmonella can be injected into tumors to flag cancer to the immune system so that it can be quickly cleared from the body, scientists have shown.
Cancer is extremely good at evading the body’s immune system, largely because a tumor is normal tissue which has gone awry, so the body does not see it as an invader.

Some cancers have also evolved to suppress or hide from the immune system.
But scientists have now shown they can use the salmonella bacteria as a ‘Trojan horse’ to infiltrate cancer cells so that the body knows they should be attacked.
