Unravelling the secret of a critical immune cell for cancer immunity

WEHI researchers have found a key differentiation course of that gives a necessary immune operate in serving to to manage cancer and infectious ailments.

The analysis, revealed in Science Immunology, is the first to indicate a new issue — DC-SCRIPT — is required for the operate a explicit sort of dendritic cell — known as cDC1 — that’s important in controlling the immune response to an infection.

Led by WEHI Professor Stephen Nutt, Dr Michael Chopin and Mr Shengbo Zhang, it defines the position for a new regulatory protein — DC-SCRIPT — in producing dendritic cells.

At a look

  • WEHI researchers have uncovered a key step in the formation of a explicit sort of dendritic cell — known as cDC1 — in controlling the immune response to an infection.
  • The analysis highlights the significance of DC-SCRIPT in the manufacturing of efficient dendritic cells.
  • Through gaining a higher understanding of how dendritic cells are produced, researchers hope to have the ability to decide a approach of directing the physique to provide massive numbers of dendritic cells, to allow it to raised combat off cancer and infections.

DC-SCRIPT important in the manufacturing of cancer-fighting cells

Dendritic cells are immune cells that activate ‘killer’ T cells, that are important for clearing viral infections and for triggering a response to cancer tumours.

Through gaining a higher understanding of how this course of works, researchers hope to have the ability to decide a approach of directing the physique to provide massive numbers of dendritic cells, to allow it to raised combat off cancer and infections.

Professor Nutt stated the analysis paper highlighted the significance of DC-SCRIPT in the manufacturing of efficient dendritic cells.

“What we found, is that without this new factor, the cells develop poorly, and their capacity to fight infection and cancer, or to clear a parasite, is diminished,” he stated.

“The next stage of our research is to try and work out how we can get the body to produce these particular dendritic cells, cDC1s, in large volumes in order to boost the body’s natural tumour response.”

Harnessing the physique’s pure response to an infection

Dr Chopin stated he was assured cDC1s held the clues to enhancing immunity to viruses and tumours.

“This paper clearly shows DC-SCRIPT is one of the regulators of dendritic cell production. As a result of this study, we’re now focussed on ways we could harness this to increase dendritic cell production,” he stated.

“We now have a biomarker to follow when we expand this elusive cell type, which we will continue to test in pre-clinical models.”

This analysis lays the basis for future research into dendritic cell manufacturing and their medical purposes in response to tumours.

“We have generated new tools, allowing us to trace these cells within the tumour and observe how they behave in the tumour environment,” Dr Chopin stated. This work was made doable with funding from the National Health and Medical Research Council and the Victorian Government.
