A Delicious Juice That Boosts Your Immunity

Imagine if a fruit juice could actually boost your health significantly, in much the same way that some drugs are purported to. Wouldn’t drinking a delicious beverage be preferable to swallowing a pill or downing a horrible tasting spoonful of medicine? If you answered “yes,” then read further to find out more.

Specialized Regulatory T Cell Stifles Antibody Production Centers

Discovery has potential implications for cancer, autoimmune disease

A regulatory T cell that expresses three specific genes shuts down the mass production of antibodies launched by the immune system to attack invaders, a team led by scientists at The University of Texas MD Anderson Cancer Center reported online in the journal Nature Medicine.

“Regulatory T cells prevent unwanted or exaggerated immune system responses, but the mechanism by which they accomplish this has been unclear,” said paper senior author Chen Dong, Ph.D., professor in MD Anderson’s Department of Immunology and director of the Center for Inflammation and Cancer.

“We’ve identified a molecular pathway that creates a specialized regulatory T cell, which suppresses the reaction of structures called germinal centers. This is where immune system T cells and B cells interact to swiftly produce large quantities of antibodies,” Dong said. Continue reading

Man and Canine Share a Joint Tumor Marker

The dog may be man’s best friend but even so it comes as a surprise that the two species share a common tumor marker. This finding comes from a joint study between scientists of the Vetmeduni Vienna and the MedUni Wien, headed by Erika Jensen-Jarolim. The researchers looked for similarities in breast cancer of dogs and women, focusing on the tumor marker CEA (carcinoembryonic antigen). They uncovered a molecule, the CEA receptor that turned out to be essentially identical in the two species. The result could lead to the rapid development of new therapeutic methods for use in dogs and humans.

Despite steadily improving methods for its diagnosis and treatment, cancer still represents one of the  Continue reading
