Immune Mechanism Could Explain Transient Immune Suppression in Acute Infections (8/5/2007)

Scientists have discovered that at the same time the immune system is vigorously attacking invading viruses or bacteria, it is unexpectedly reducing its production of a particular type of factor that directs the movement of immune cells. The new finding, which could help explain the transient immune suppression often seen during acute infections, shows that the immune system is even more complex than previously believed. ...> Full Article

Cancer Stem Cells Created By Two Signalling Pathways (8/4/2007)

The linking of two signalling pathways in the cells of liver tumours has a clear influence on their malignancy. Activation of the platelet-derived growth factor (PDGF) messenger molecule is decisive for this linking. This results related to the development of liver cancer was generated during a current project by the Austrian Science Fund FWF and has been published in the Journal Oncogene. When the signalling pathways in liver tumour cells have been linked together, these cells develop the characteristics of cancer stem cells, which are in principal resistant to chemotherapy. This new understanding of the signalling pathways involved unlocks potential for the future development of modified therapies. ...> Full Article

Caffeine and Exercise Can Team Up to Prevent Skin Cancer (8/3/2007)

Regular exercise and little or no caffeine has become a popular lifestyle choice for many Americans. But a new Rutgers study has found that it may not be the best formula for preventing sun-induced skin damage that could lead to cancer. Low to moderate amounts of caffeine, in fact, along with exercise can be good for your health. ...> Full Article

Islet Cell Transplants Using Magnetocapsules To Cure Type I Diabetes (8/2/2007)

For patients with type 1 (juvenile) diabetes, a transplant of insulin-producing cells is a possible alternative to daily insulin injections to keep blood sugar under control. As with any transplant, however, the still-experimental technique carries the risk of rejection by the patient's immune system, meaning patients must take powerful immunosuppressive drugs. A new delivery vehicle for the transplanted cells may help overcome this obstacle, while also allowing clinicians to track the cells once they are inside the body. ...> Full Article
