Some Cancers Cloak Themselves from the Immune System’s Discovery

Immunotherapy cancer treatment is designed to aid the body’s immune system in recognizing and attacking tumor cells. Scientists are finally uncovering clues as to how cancer cells are able to evade detection by the body’s natural defenses.

How Cancer Blocks the Immune System

The first steps were taken in 2009 by a team headed up by Dr. Irving Weissman, director of Stanford’s Institute for Stem Cell Biology and Regenerative Medicine. Their research discovered that some cancer cells are able to emit a “don’t eat me” signal.

High levels of CD47, a transmembrane protein, are found on the surface of more aggressive cancer cells. CD47 then binds with another protein called SIRPalpha on the surface of macrophages, a type of white blood cell, inhibiting their ability to attack cancer cells.

In 2017, Dr. Weissman’s team published the results of a recent study that identified another protein that interferes with macrophage activity. When MHC class 1 binds with a protein known as LILRB1, it’s resistant to an antibody that has been used successfully to counteract CD47 in tests on mice with cancer.

Applications for Immunotherapy Cancer Treatment

Cancer research is complicated by the fact that different types have different “fingerprints.” The studies conducted by Dr. Weissman’s team are helping scientists learn more about strategies to “outwit” cancer cells and their ability to avoid detection.

Molecularly Targeted Therapy – Considered Exciting Cancer News

Molecular Targeted Therapy Hit the Bulls Eye!
Molecular Targeted Therapy Hit the Bulls Eye!

Traditional cancer treatments often attack both cancer and healthy cells, resulting in debilitating side effects such as fatigue and weight loss. Doctors are excited about a revolutionary cancer treatment that specifically targets cancer cells.

Cancer Treatment that “Hits the Bullseye”

As implied by the name, molecularly targeted therapy involves drugs designed at the molecular level of the cell to attack and destroy specific types of cancer. Glivec (or Gleevec), also known as STI571, is the pioneering drug in this promising new therapy.

These so-called “designer drugs” begin with the identification of an abnormal molecule unique to a particular type of cancer. Scientists can then create a drug that interferes with the function of that molecule.

Glivec: Targeting Leukemia

Glivec has been found to be effective against chronic myeloid leukemia, also known as CML. Dr. Brian Druker, who led the research on Glivec, discovered that scientists have previously used STI571 to treat a rare gastrointestinal cancer that shares an enzyme related to one in CML.

Dr. Druker, who also serves as director of the leukemia program at the Oregon Health Sciences University, believes that STI571 can lead the way in finding the abnormalities in other types of cancer so they can also be treated with molecularly targeted therapy.

FDA approval of Glivec was fast-tracked and the drug is now available from Novartis Pharmaceuticals.
