Mitochondria on the move: Leveraging intercellular mitochondria transfer to boost cancer immunotherapies

An international team of researchers, led by Professor Luca Gattinoni at the Leibniz Institute for Immunotherapy (LIT), has developed an innovative mitochondrial transfer platform to supercharge CD8+ T cells, enabling them to overcome exhaustion and more effectively fight tumor cells.

Background Research:

The mitochondrial transfer is a process that involves the movement of mitochondria from one cell to another. Recent research has demonstrated that this process is not just a random event, but instead a regulated pathway with specific cellular and molecular mechanisms involved. In earlier studies carried out by Prof. Gattinoni’s group at the Leibniz Institute for Immunotherapy (LIT), it was shown how the manipulation of these mechanisms can enhance the anti-tumor properties of certain immune cells in patients with cancer.

CD8+ T cells play a crucial role in our immune system’s fight against cancer. They can recognize and kill tumor cells directly; however, their function often decreases or „exhausts“ during chronic infections or in response to cancers, compromising our body’s ability to effectively defend against disease.

FAQs:

1. What is mitochondrial transfer?

Mitochondrial transfer is the movement of mitochondria (the power generators within our cells) from one cell to another which alters cell functions substantially.

2. How does this discovery benefit cancer immunotherapies?

This discovery introduces an innovative way to supercharge CD8+ T cells‘ fight against tumor cells by supplying them with extra energy via transferred mitochondria.

3. What role do CD8+ T Cells play in fighting diseases such as cancer?

CD8+ T Cells are key players in our immune systems as they can detect and eliminate disease-ridden or cancerous cells directly within our bodies.

4.What does it mean when CD8+ T Cells become „exhausted“?

When they’re described as “exhausted,” it means these particular T Cells have been working very hard over time–therefore are less effective –usually due either chronic infection load or enduring response needed for tackling cancers and more challenging invaders like viruses.

5.Who led this research project?

The project was led by Professor Luca Gattinoni at the Leibniz Institute for Immunotherapy (LIT).

6. What is the next step after this discovery?

While this research provides exciting opportunities to boost cancer immunotherapies, there remain crucial steps including clinical studies and therapeutic model development for bringing these findings into practical, medical use.

Neuartige Methode zur Tumorbekämpfung: Carl-Zeiss-Stiftung fördert Projekt der Hochschule Aalen mit einer Million Euro

Die bisherige Krebstherapie effizienter gestalten bei deutlicher Reduzierung der Nebenwirkungen auf gesundes Gewebe – dies ist das Ziel eines Projekts von Prof. Dr. Andreas Walter, der an der Hochschule Aalen lehrt und forscht. Gefördert wird es mit einer Million Euro von der Carl-Zeiss-Stiftung. Hierzu entwickelt der Biophysiker mit seinem Team neuartige Nanopartikel aus Gold. Die Partikel setzen Strahlen- und Chemotherapie gleichzeitig ein und töten die Krebszellen gezielt ab. Für die Auswertung werden skalenübergreifende bildgebende Verfahren an der Hochschule Aalen entwickelt.
