Cancer's ability to elude our body's immune system has long puzzled researchers. The latest study pinpoints one of cancer's protective cloaks and investigates a way to remove it.

Cancer cells are cells that have gone awry; they both multiply unchecked and function incorrectly. Normally, cells that are faulty, dead, or dying are cleared away by the immune system.

Macrophages — a type of white blood cell — are largely responsible for the consumption and destruction of foreign invaders and errant cells.

Although macrophages normally carry out their attacks with ruthless efficiency, some cancer cells manage to evade their roaming gaze. How do cancer cells fly under the immune system's radar?

Scientists demonstrated that particularly aggressive cancer cells express higher levels of CD47 — a transmembrane protein — on their cell surface. CD47 binds to a protein called SIRPalpha on the surface of macrophages, reducing their ability to attack and kill the cancer cells.

Studies in animals have shown that treatment with an anti-CD47 antibody significantly increases macrophages ability to kill cancer cells. In some mouse models of cancer, the treatment even led to a cure. Clinical trials are underway to gauge whether this approach will be as successful in humans.

hmm how fascinating . i had been to Zen Meditation training came where they had told me that Doing Zen Meditation Creates Delta waves in our brain . Basically Alpha waves are not the only waves created by the interaction of neurons , there are different kinds of waves created in different moods , and while doing different tasks But Alpha waves are said to be created when you are mostly relaxed
