Sleeping immune cells in tumours can be ‘woken up’ to fight cancer

Sleeping immune cells which are already in tumors can be ‘woken up’ to fight even the most deadly cancers, scientists have discovered.
In order to evade the body’s defense mechanism, cancer cells have learned to flick a switch in immune cells which switches them off.

The switch is there to stop the body wrongly attacking harmless invaders, and is the reason that a mother can carry a baby – essentially a foreign body – without the immune system attacking the fetus.

Now scientists at Cancer Research UK and University College London have proven it is possible to use genetic editing to snip away the ‘off switch’ so that the immune system recognizes cancer again.
