Using Dendritic Cells to Fight Head and Neck Cancers

Head and Neck Cell Cancers (HNC) includes cancers within the oral cavity, sinonasal cavities, pharynx and larynx. HNC is the 6th most common cancer in the world with roughly 550,000 diagnoses each year.

Head and Neck Cancer Overview

Unfortunately, this frequently encountered cancer has a relatively high mortality rate and poor side effect profile associated with common treatments¹.

While all cancer types at some level avoid detection by the Immune System, HNC excels at hiding². HNC’s consistent ability to do so has been of great interest within Cancer Immunotherapy research. Fortunately, researchers have recently uncovered what they believe is the secret weapon of Head and Neck Cancers.

The Immune System’s Role in Fighting Cancer

As with any mutated cell in the body, the Immune System is responsible for detecting the mutations and eliminating the cell. This can be divided into three phases:

Immune response initiated by Dendritic Cells
Activation of specific T cells to target the cancer
Destruction of the cancer by the targeted T cells

To see this in action, see below!

However, if the Immune System fails to detect the mutated cell, that single cell can rapidly grow and eventually turn into deadly tumors. And as mentioned above, Head and Neck Cancers are particularly adept at avoiding detection.

HNC Actively Evades the Immune System

Fortunately, the basis of Head and Neck Cancer’s superior ability appears to be finally known. Recent studies have identified that many HNCs secrete “Extracellular Vesicles” (or EVs) which are able to promote tumor survival and growth via a number of different mechanisms³.

One these mechanisms is Head and Neck Cancer’s ability to prevent localized Dendritic Cells from maturing and therefore preventing an immune attack^4,5. This is particularly bad news.

Oncology research has repeatedly demonstrated that disruptions in Dendritic Cell activity is one of the most effective strategies for tumors to avoid destruction and continue progression^6,7.

Immunocine’s Dendritic Cell Treatment Can Fight HNC

Fortunately, Dendritic Cell Treatments that properly activate Dendritic Cells to attack Head and Neck Cancers can overcome this issue. To empower an HNC-targeted Immune Response, the Dendritic Cells need to be:

Cognizant of the cancerous threat
Loaded with the complete Cancer Antigen profile in the absence of HNC Extracellular Vesicles
Stimulated to initiate an TH1 response, which is specific to destroying mutated and virally infected cells

While this is simple list, Immunocine provides the only Dendritic Cell Treatment that accomplishes all three. Backed by peer-reviewed scientific publications, clinical trials, and patents, Immunocine’s cancer treatment unique process explains why our team has seen success in HNC patients, where other Immunotherapies have not.

*Outside of cancer, the term Antigen can be used to describe any foreign molecules that would trigger an immune response. The Immunocine Science Team did not want to upset any of our fellow immunologists!

Inflammation in Cancer

In today’s world, chronic inflammation is an ever-present challenge linked to serious diseases, notably cancer. However, the paradox arises when we consider immunotherapy—a treatment harnessing inflammation to combat cancer. The key to understanding this complex interplay lies in precise “targeting” of the immune system’s arsenal. While chronic inflammation can fuel cancer, abandoning it entirely …
