Stem cells, the prodigious precursors of all the tissues in our body, can make almost anything, given the right circumstances. Including, unfortunately, cancer. Now research from Rockefeller University shows that having too many stem cells, or stem cells that live for too long, can increase the odds of developing cancer. By identifying a mechanism that regulates programmed cell death in precursor cells for blood, or hematopoietic stem cells, the work is the first to connect the death of such...

In order to track down pathogens and render them harmless, the immune system must be able to recognize myriad different foreign substances and react to them. Scientists at the Max Planck Institute of Immunobiology and the Centre for Biological Signalling Studies BIOSS at the University of Freiburg have discovered how the immune system's B-cells can be activated by numerous substances from our environment. The receptor molecules on the surface of the B-cells are only activated when the...

A protein called PU.1 is essential for the development of dendritic cells, the sentinels of the immune system, Walter and Eliza Hall Institute researchers in Melbourne, Australia, have shown. Dendritic cells (DC) are immune cells that present proteins from foreign invaders, such as viruses, to the killer T cells of the immune system, allowing a full immune response to be mounted against the invaders. Researchers from the Immunology division have been studying dendritic cells and how different...

Researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James) have identified an experimental agent that targets chronic lymphocytic leukemia and perhaps other proliferative disorders of lymphocytes. Their study shows that the small-molecule inhibitor CAL-101 directly promotes cell death by apoptosis in chronic lymphocytic leukemia (CLL) cells and disrupts several external survival pathways needed...

New finding may pave the way to the development of drugs for treating the disease According to a new study a protein crucial for the immune response appears to be a key player in the progression of a devastating form of childhood leukemia called T-cell acute lymphoblastic leukemia (T-ALL). Suppressing the activity of the protein kills the leukemic cells, the study shows, opening a potential avenue to new drugs that could prevent progression of the disease. Led by Iannis Aifantis, PhD,...

(Ivanhoe Newswire) -- We've all heard about the potential medical benefits of stem cells. Now, researchers have created a synthetic surface that allows stem cells to stay alive and continue reproducing for at least three months. Human pluripotent stem cells can become any other kind of body cell. These types of cells have shown great promise in treating conditions such as Parkinson's disease, multiple sclerosis and spinal cord injuries. However, one challenge faced by scientists has been...

Mushrooms are among the many foods thought to play an important role in keeping the immune system healthy. Now, Agricultural Research Service (ARS)-funded scientists have conducted an animal-model and cell-culture study showing that white button mushrooms enhanced the activity of critical cells in the body's immune system. In the United States, white button mushrooms represent 90 percent of the total mushrooms consumed. The study was conducted at the Jean Mayer USDA Human Nutrition Research...

This discovery may generate new strategies to fight serious human diseases, and devastating plant blights--including the type of blight involved in the Irish Potato Blight. A study published in the July 23 issue of Cell identifies the mechanism used by several types of common, virulent microbes to infect plants and cause devastating blights. Microbes using this infection mechanism include fungi that are currently causing wheat rust epidemics in Africa and Asia, and a class of parasitic algae,...

A research team led by scientists at the Virginia Bioinformatics Institute (VBI) at Virginia Tech has discovered a fundamental entry mechanism that allows dangerous fungal microbes to infect plants and cause disease. The discovery paves the way for the development of new intervention strategies to protect plant, and even some animal cells, from deadly fungal infections. The findings are published in the July 23 edition of the journal Cell. The researchers have revealed how special...

Immune system cells called macrophages spring into action to surround and destroy threats such as viruses or cancer cells. But sometimes the would-be protective response leads to persistent inflammation, which, in turn, can cause disease. Scientists don't know exactly how macrophages cross the line from being good cops to bad cops, but researchers at the University of Florida recently unearthed several clues about the mechanisms involved. Through the lens of two inflammation-related diseases,...

Thymus
2013-03-04 12:56:08

The thymus gland is an endocrine organ of the immune system located anteriolateral to the trachea and in between the lungs. Its primary function is to build T lymphocytes for the body’s immune system; therefore, it is most important during childhood and puberty, when it reaches its maximum size. After puberty, it will begin to atrophy and shrink in size. Old age generally brings about hypotrophy of the thymus. In children the thymus is grayish-pink in color and in adults it is yellow. On...
