Re: Cancer & The Immune System

Immunity and Cancer
When normal cells turn into cancer cells, some of the antigens on their
surface change.

These new or altered antigens flag immune defenders, including cytotoxic T
cells, natural killer cells, and macrophages. According to one theory,
patrolling cells of the immune system provide continuing bodywide
surveillance, spying out and eliminating cells that undergo malignant
transformation. Tumors develop when the surveillance system breaks down or
is overwhelmed.

Kaposi's sarcoma is an depleted immune system cancer.

It's also caused by a virus, which is not true of most cancers.
(Cervical cancer is another.)

Cancer-Proof Mouse With Anti-Cancer Immune System Discovered
Normally if a cancer cell line is injected into a mouse the cancer cells
grow. Some scientists at Wake Forest University discovered a mouse that was
immune to injected cancer and have bred it and produced many generations of
cancer-proof mice.

A cancer-proof mouse, which can survive being injected with any number of
cancer cells, has been discovered by US scientists. The discovery of the
resistant mouse could pave the way for future gene or drug therapies if the
mechanism by which it fights cancer can be understood

This is amazing for a few different reasons. First, it is amazing that it is
possible at all. An immune system that can kill such a large variety of
types of cancer which does not appear to cause auto-immune disorders is not
something I would have expected to be possible. Cancer cells look too much
like normal cells and most cancers (perhaps virally caused cancers are an
exception) are probably expressing only genes that naturally are expressed
in human cells. So where does the specificity come from that lets an immune
system knock out a large variety of cancers? Just figuring it out will
reveal very useful knowledge.

What is also amazing about it is that the mutation happened and someone
noticed. It is hard to say what the odds are for the occurrence of a mutant
that would have the resistance to cancer.until it is discovered how the
mechanism works and how many mutations had to happen for a mouse to have
cancer resistance. Still, it seems amazing to me.

This is the clincher :-

http://www.research.vt.edu/resmag/sciencecol/cancer97.html
Recently, it was discovered that Mfs help regulate infections and tumors
through the production of interleukin (IL)-12, a vital communication
molecule between Mfs and other immune cells. What if Mfs don't produce
enough IL-12? Elgert's research has demonstrated that Mfs in animals with
tumors make less IL-12.

In addition, the researchers have discovered that the impact is not just
limited to the tumor, but the immune system throughout the body is
compromised, Elgert says.

Cancer is a compromised immune system (Elgert.)
