Natural Killer (NK) Cell Therapy — Immune-Based Cancer Support
Natural killer (NK) cell therapy harnesses the body's own immune cells — a type of white blood cell that detects and destroys infected or cancerous cells — to support the fight against cancer and other conditions.
Quick answer
Natural killer (NK) cell therapy uses NK cells, a type of white blood cell central to immune surveillance, to help identify and destroy cancerous or infected cells. At Viezec it is explored for various cancers and as immune support, often alongside other immunotherapies such as dendritic cell therapy.

Understanding the approach
What Is Natural Killer (NK) Cell Therapy?
Natural killer (NK) cells are a type of white blood cell that plays a central role in the immune system's ability to identify and destroy infected or cancerous cells. NK cell therapy uses these cells therapeutically to help fight cancer and other conditions.
Immune Surveillance
NK cells naturally detect and kill infected or cancerous cells.
Cell Expansion
Therapy involves boosting NK cell numbers or activity for therapeutic use.
Targeted Action
NK cells can be directed against specific types of cancer.
Complementary Role
May be used alongside conventional treatments to support overall immune function.
Where it's used
Conditions NK Cell Therapy Can Support
NK cell therapy is explored for cancer and other conditions where immune support plays a central role.
- Various cancer types
- Autoimmune conditions
- General immune support during illness or recovery
- Cases where improved resistance to infection is a treatment goal
- Combined use with other immunotherapies such as dendritic cell therapy

Frequently Asked Questions
What is natural killer (NK) cell therapy?
NK cell therapy uses natural killer cells — a type of white blood cell that identifies and destroys infected or cancerous cells — to support the immune system's fight against cancer and other conditions.
Is NK cell therapy only used for cancer?
No. While cancer is a primary application, NK cell therapy is also explored for autoimmune diseases and general immune support.
How does NK cell therapy work?
NK cells can be directed against specific types of cancer cells, helping to destroy tumor tissue and support the patient's overall immune response.
Is NK cell therapy combined with other treatments?
Yes. It is often used alongside conventional cancer treatments or other immunotherapies such as dendritic cell therapy as part of a broader care plan.
What are the potential benefits of NK cell therapy?
Reported potential benefits include improved overall health, increased resistance to infection, and reduced disease-related symptoms.
Who should evaluate whether NK cell therapy is appropriate?
A qualified oncologist or immunologist should review the specific condition and current evidence before considering NK cell therapy.
How is natural killer cell therapy administered?
NK cells are typically expanded outside the body and then reinfused intravenously, with the number of cycles determined by the treating oncology team.
Is NK cell therapy considered experimental?
Regulatory status varies by country and specific application; patients should discuss current evidence and approval status for their condition with their care team.
