Scientists Find Control Signal For Immune System That Could Help Treat Autoimmune Diseases And Cancer
2014-08-18 03:19:20

Salk Institute When faced with pathogens, the immune system summons a swarm of cells made up of soldiers and peacekeepers. The peacekeeping cells tell the soldier cells to halt fighting when invaders are cleared. Without this cease-fire signal, the soldiers, known as killer T cells, continue their frenzied attack and turn on the body, causing inflammation and autoimmune disorders such as allergies, asthma, rheumatoid arthritis, multiple sclerosis and type 1 diabetes. Now, scientists at...

In animal studies, CHOP researchers advance new approach to anti-tumor immunotherapy By carefully adjusting the function of crucial immune cells, scientists may have developed a completely new type of cancer immunotherapy—harnessing the body's immune system to attack tumors. To accomplish this, they had to thread a needle in immune function, shrinking tumors without triggering unwanted autoimmune responses. The new research, performed in animals, is not ready for clinical use in...

The tiny thymus teaches the immune system to ignore the teeming, foreign bacteria in the gut that helps you digest and absorb food, researchers say. When immune cells recognize essential gut bacteria as foreign, inflammatory bowel disease such as ulcerative colitis and Crohn's disease can be the painful, debilitating result. In a study published in the journal Nature, researchers show that the regulatory T cells, or Tregs, that keep this from happening in most of us come from the tiny...

Researchers at the Moffitt Cancer Center have found that delayed tumor growth and enhanced survival of mice bearing melanoma were possible by blocking the reconstitution of myeloid-derived suppressor cells and Tregs (suppressors of anti-tumor activity) after total body irradiation had eliminated them. Blocking myeloid-derived suppressor cells and regulatory T-cell reconstitution improved adoptive T-cell therapy, an immunotherapy designed to suppress tumor activity. The study appears in the...
