Fatty membrane helps regulate immune system A fatty membrane in the belly called the omentum has until recently been considered somewhat like the appendix -- it didn't seem to serve much purpose. But Loyola University Chicago Stritch School of Medicine researchers have found that the omentum appears to play an important role in regulating the immune system. The finding could lead to new drugs for organ transplant patients and patients with auto-immune diseases such as lupus and Crohn's...

Bone Repair Via Stem-cell-growing Surface
2012-05-24 08:19:47

Connie K. Ho for RedOrbit.com Technology is rapidly progressing and so is research related to stem cells. Researchers from the University of Michigan recently announced that they found a special surface without biological contaminants that can help adult-derived stem cells to grow and change into different cell types. The findings, published in the journal Stem Cells, are considered a breakthrough in stem cell research. In the study, scientists grew bone cells on the surface and then...

If you throw a rubber balloon filled with water against a wall, it will spread out and deform on impact, while the same balloon filled with honey, which is more viscous, will deform much less. If the balloon's elastic rubber was stiffer, an even smaller change in shape would be observed. By simply analyzing how much a balloon changes shape upon hitting a wall, you can uncover information about its physical properties. Although cells are not simple sacks of fluid, they also contain...

A new study describes a therapeutic approach to halting cancer progression by exploiting a previously unrecognized "addiction" of leukemia cells to specific signaling molecules. The research, published by Cell Press online on April 16th in the journal Cancer Cell, identifies non-classical oncogenes critical for tumor development and survival, and describes a potentially less toxic strategy that selectively targets these molecules. Many cancers are associated with the loss of function of...

Inhibiting 2 related enzymes significantly improves survival in mouse model of the disease Columbia University Medical Center (CUMC) scientists have demonstrated that two related enzymes – phosphoinositide-3 kinase (PI3K) gamma and delta – play a key role in the development of T-cell acute lymphoblastic leukemia (T-ALL), a highly aggressive childhood leukemia that is difficult to treat. The study also showed that a dual PI3K gamma/delta inhibitor can significantly prolong...

Researchers at the University of Liverpool have resolved the debate over the mechanisms involved in the shut-down process during cell division in the body. Research findings, published in the journal PNAS, may contribute to future studies on how scientists could manipulate this shut-down process to ensure that viruses and other pathogens do not enter the cells of the body and cause harm. Previous research has shown that when cells divide, they cannot perform any other task apart from...

New method for direct identification of antigens The immune system is a vital part of our defenses against pathogens, but it can also attack host tissues, resulting in autoimmune disease. The antigens that induce destructive immune reactions can now be identified directly — without any prior knowledge of their possible structure. Molecules that activate immune responses, generically termed antigens, are recognized by circulating immune cells. In the case of autoimmune reactions,...

Finding may help develop new treatments for infectious diseases, cancer UCLA researchers pinpointed a new mechanism that potently activates T-cells, the group of white blood cells that play a major role in fighting infections. Published March 25 online in Nature Medicine, the team specifically studied how dendritic cells, immune cells located at the site of infection, become more specialized to fight the leprosy pathogen known as Mycobacterium leprae. Dendritic cells, like scouts in the...

Researchers identify 190 genes crucial to the function of TLR7 and TLR9, cellular sensors that recognize pathogens and trigger immune responses -- providing insights that could be exploited to develop new therapies for infectious and autoimmune diseases In a healthy immune system, invading pathogens trigger a cascade of alerts and responses to fight off the infection. Sensors called toll-like receptors, or TLRs, act as one of the first lines of defense. Two of these sensors, known as TLR7...

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...

  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
