A Tactical Battle: Cancer vs. The Immune System

Your immune system has evolved to detect anything in the cell that does not belong in your body.  Pathogens, dying cells, and mutated cells tend not to fare very well once the immune system detects them.  In this regard, cancer is no exception.  Previous studies have found that elevated levels of CD8+ T cells, the same cells responsible for killing cells that are infected with viruses, are correlated with elevated rates of survival and spontaneous cancer recovery in clinical studies.  Similar studies have found other immune cells, such as natural killer cells, macrophages, and CD4+ T cells either directly or indirectly help the body combat cancer.  In fact, this spontaneous recovery of cancer due to the immune system has often caused patients to accuse doctors of over diagnosing cancer cases, as the immune system can often act before doctors can follow up with cancer patients or even consider beginning treatment. 

Unfortunately, while cancer cells have many differences when compared to healthy cells, and although the immune system is capable of detecting these differences, successful tumors are able to manipulate the immune system to essentially blend in as ‘self.’  These cancerous cells do this by activating the regulatory branch of the adaptive immune system- including regulatory T cells.  This is why in many models tumor growth is observed to occur in two phases: one phase where the immune response is high and the tumor growth is slow followed by a second stage with little immune activity and rapid growth and metastasis of the cancer.  Therefore, while the immune system is critical for the early stages of controlling cancer, the unfortunate fact remains that once the body begins to fight off cancer cells, the cells are able to alter the cellular environment in such a way that the immune system actually begins to help the cancer by any further immune response against it.  Interestingly, break in the immune system’s attack on the cancer allows the tumor to grow to a large enough size that it can begin to secrete chemicals that can kill immune cells off- reducing its dependency on the regulatory immune system.

These illustrations were a lot of fun to do, and I always love getting to draw landscapes, especially if they have anything to do with the ocean.

We blindfolded 15 homophobes and asked them to hit piñatas with a stick. The piñatas were actually deadly Asian giant hornet nests. What happens next will warm your heart.

A 2007 Rhode Island study looked at 30 men and 30 women who had just had coronary-artery bypass surgery and tracked the medications they were given. The researchers were astonished to find that men got pain medications, while women got sedatives. With chronic pain problems, women’s symptoms are often minimized.
