What is immunotherapy and how does it treat cancer and other conditions?

From infections and allergies to brain diseases and autoimmune disorders, a wave of trials offers hope

Ian Sample, the Guardian

Liston, the cofounder of Cambridge spin-out Aila Biotech, is developing a Treg therapy for multiple sclerosis, a disease caused by immune cells attacking the nervous system by mistake. The therapy aims to boost Tregs in the brain to call the attack off.

The potential for Tregs is vast. Therapies are in the pipeline for dementia and autoimmune diseases from type 1 diabetes and rheumatoid arthritis to lupus and chronic inflammation.... “Probably half of all deaths have a component that is immunological,” says Liston. “It is an underlying theme across ageing, autoimmune diseases, allergies, infectious diseases, inflammatory diseases like diabetes. But one of the great things about the immune system is that it is very easy to change. We can adapt it to our purposes.”
