Trojan horse injections help human body fight cancer

Trojan horse injections help human body fight cancerGerman researchers presented a “Trojan horse” method of attacking cancer, sneaking virus impersonators into the human body which prompt an immune response that attacks tumours.

Tested in only three people so far, the treatment claims to be the latest advance in immunotherapy, which aims to rouse the body’s own immune system against disease.

Made in the lab, the Trojan horse is composed of nanoparticles containing cancer RNA – a form of genetic coding – enclosed by a fatty acid membrane.

The particles are injected into patients to simulate a viral infection, and infiltrate specialised immune cells. These dendritic cells decode the RNA embedded in the nanoparticles – triggering, in turn, the production of cancer antigens.

The antigens then activate cancer-fighting T cells, and thus prime the body to attack tumours.

Following experiments in mice, three people with advanced skin cancer were given low doses of the treatment, in the first step of the long and cautious process to test new drugs on humans.

All developed a “strong” immune response, the team reported in the journal Nature.

If further trials find the therapy works, they added, the method could help pave the way to a treatment for all cancer types.

The new treatment is called an RNA vaccine – it works just like a preventive vaccine by mimicking an infectious agent and training the body to respond to it.
