Dendritic cells are named for their long, branching arms (dendron is Greek for tree). They sit in the skin, the lining of the gut and lungs, and the blood, constantly sampling their surroundings. They don't usually destroy threats themselves. Their role in the immune system is to collect evidence and train the cells that do.
Dendritic cell therapy
Dendritic cell therapy is a personalised immunotherapy that aims to teach your immune system to recognise cancer. It uses your own dendritic cells, the cells whose job is to show the rest of the immune system what to attack.

01 / Overview
About Dendritic Cell Therapy
02 / How it works
How Dendritic Cell Therapy works
Dendritic cells train the immune system in three key steps:
- Collect. A dendritic cell swallows fragments of an abnormal cell, including the protein markers (antigens) that make it different from healthy tissue.
- Travel. It carries those fragments to the nearest lymph node, the immune system's training ground.
- Teach. There, it displays the antigens to T-cells. T-cells that recognise the antigen are switched on, multiply into an army and travel through the body looking for cells carrying the same marker. Some become memory T-cells, which can respond again if the marker returns.
The key difference between Dendritic and NK cell therapy is that NK cells act straight away against any cell that looks abnormal whereas Dendritic cells work more slowly, but the response they start is targeted at specific markers.

03 / When it is considered
When this treatment may be considered
Dendritic cell therapy is usually considered when the immune system may need help recognising a cancer, either because the tumour is suppressing dendritic cells or because standard treatments have reduced the immune system's overall strength.
Suitability is assessed individually. Our doctors look at cancer type and stage, current and recent treatments, whether tumour tissue is available, blood counts and overall health.

04 / The process
How Dendritic cell therapy works
- 1. Collection
- White blood cells are collected from your blood, often by a process called apheresis that filters out the cells needed and returns the rest.
- 2. Growing the cells
- In a specialised laboratory, precursor cells called monocytes are grown into dendritic cells over about one to two weeks.
- 3. Loading
- The dendritic cells are exposed to cancer antigens. These may come from your own tumour tissue (tumour lysate), or from synthetic proteins found on your type of cancer. Researchers call this "pulsing" or "loading" the cells.
- 4. Maturing and returning
- The cells are activated, then given back as a series of injections, usually into the skin near a lymph node or into a vein.
05 / Care at Verita Life
Your care at Verita Life
Our doctors consider cellular treatments in the context of your full oncology plan. Bring pathology, recent scans, and details of previous immune treatments so uncertainties and alternatives can be discussed openly.
06 / Risks and limitations
Risks and limitations
Across more than two decades of trials, dendritic cell therapy has been well tolerated. The most common side effects are redness or swelling where the injection was given, and short-lived flu-like symptoms such as mild fever, chills or tiredness for a day or two. Serious side effects are uncommon.
As with any treatment, side effects are possible and results vary by individual.

07 / Questions
Questions patients ask
Is dendritic cell therapy a cancer vaccine?
It is often called one, but it is a treatment vaccine, not a preventive one. It is given to people who already have cancer, with the aim of training their immune system to recognise the cancer. It does not prevent cancer in healthy people.
How is dendritic cell therapy different from NK cell therapy?
NK cells attack abnormal cells directly and quickly, without needing to be trained. Dendritic cells don't attack cancer themselves; they teach T cells which specific markers to target. The two are sometimes considered together because they act on different parts of the immune system.
