- Scientists discover how cancer may take hold
09-24-2007 · EurekAlert!
A team, led by researchers at the Carnegie Institution, has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated. The research shows how the biomolecules responsible for healthy T cells, the body's first defenders against hostile invaders, are quashed, permitting the invading cancer to spread. The same cycle could also be involved in autoimmune diseases such as multiple sclerosis.

What if doctors could peer through a patient's skin and see a cancer tumor growing? They'd be able to study how tumor cells migrate: how they look, how they interact with the blood system to find nourishment to grow and spread through the body. Scientists at the UCSD School of Medicine can't look through human skin. But a small, tropical minnow fish common to aquariums has given researchers a window for viewing live, human cancer cells in action.

- Scientists discover a direct route from the brain to the immune system
10-24-2007 · EurekAlert!
It used to be dogma that the brain was shut away from the actions of the immune system, shielded from the outside forces of nature. But that’s not how it is at all. In fact, thanks to the scientific detective work of Kevin Tracey, MD, it turns out that the brain talks directly to the immune system, sending commands that control the body’s inflammatory response to infection and autoimmune diseases.

- Cancer stem cells: know thine enemy
12-21-2007 · EurekAlert!
Stem cells, popularly known as a source of biological rejuvenation, may play harmful roles in the body, specifically in the growth and spread of cancer. Amongst the wildly dividing cells of a tumor, scientists have located cancer stem cells. Physician-scientists from Weill Cornell Medical College are studying these cells with hopes of combating malignant cancers in the brain.

- Weizmann Institute scientists discover genes that can slow cell division and may fight cancer
02-26-2007 · EurekAlert!
When cells begin to divide, they also activate a "braking system" that eventually stops cell division. When this system is faulty, uncontrolled cell division and the growth of cancer can result. Weizmann Institute scientists have identified a number of the genes involved in this braking system. Identification of the exact factors causing uncontrolled cell division may lead to the development of advanced treatments for cancer.

- How cancer spreads by aggregating platelets
08-30-2007 · EurekAlert!
Scientists have provided new details about how cancer cells spread by surrounding themselves with platelets -- the blood cells needed for blood clotting. These results could help design new drugs that prevent cancer cells from metastasizing, or spreading throughout the body.

- Jefferson scientists find protein helps pancreatic cancer cells evade immune system and spread
01-10-2008 · EurekAlert!
A protein that helps prevent a woman's body from rejecting a fetus may also play an important role in enabling pancreatic cancer cells to evade detection by the immune system, allowing them to spread in the body. Researchers found that the metastatic pancreatic cancer cells in the lymph nodes produce enough of the protein, IDO, to wall-off the immune system's T-cells and recruit cells that suppress the immune response to the tumor.
