The tumour
as a dynamic process

In tumour therapy, immunogenic cell death (ICD) is an important component to induce a cytotoxic tumour-specific immune reaction against the tumour cells or tumour cell growth. This reaction can inhibit tumour growth.

There are 80 centres worldwide involved in the consensus guidelines for the definition, recognition and interpretation of immunogenic cell death. Within this framework, the IOZK working group contributes to support through oncolytic virotherapy and loco-regional modulated electrohyperthermia.

ICD - The induction
of immunogenic cell death

Today, basic research knows many types of cell death.
One type of cell death can trigger an immune reaction against the structures of the deceased cells, this is immunogenic cell death (ICD).

The past 30 years have shown that we can target and manipulate the immune system against cancer cells. There are now anti-tumour agents and treatments that result in immune stimulation - one example is a virus that can infect and destroy a cancer cell. We have found over time that in addition to this oncolytic activity of the virus, the subsequent immunisation that occurs due to the killing of the tumour cells is equally important. This process is called immunogenic cell death (ICD).

The particular importance of immunogenic cell death is well known, but in reality it occurs very rarely. If a cell dies in the body, the immune system usually does not care; this is a good thing, because otherwise the body would explode in a minute if the immune system reacted immediately to every dying cell. In contrast, immunogenic cell death is a type of cell death in which the immune system is alerted and an immune response is triggered as a consequence. An anti-tumour strategy is therefore to specifically induce immunogenic cell death by infecting the tumour cells with an oncological virus.
