Chemical from Medicinal Plants May Be Used to Fight HIV

Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised.
But a new UCLA AIDS Institute study has found that a chemical from the Astragalus root, frequently used in Chinese herbal therapy, can prevent or slow this progressive telomere shortening, which could make it a key weapon in the fight against HIV 
Scientists turbo-charge immune cells to fight cancer

Scientists in the United States have created super-charged immune cells that helped beat back cancer tumors in half of a small group of patients tested, according to a study released Sunday.
Adding an artificial receptor to T-lymphocyte immune cells boosted their ability to fight a deadly form of cancer called neuroblastoma, the researchers reported.
Neuroblastoma attacks the nervous system. While fairly rare, it accounts for seven percent of all childhood cancers, and fifteen percent of non-adult cancer deaths
How the Body Determines Optimal Amount of Germ-Fighting B Cells

Researchers at the University of Pennsylvania School of Medicine can now explain how the body determines whether there are enough mature B-cells in the blood stream at any one time. These are the cells that produce antibodies against germs to fight infections.
“There is a steady state number of B cells that is considered normal for humans,” says senior author Michael P. Cancro, PhD, Professor of Pathology and Laboratory Medicine
New Role for Critical DNA Repair Molecule in Immune System

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA. New research published in Nature shows for the first time that a molecule devoted to DNA repair plays a broader role in this genetic reshuffling — called recombination — than scientists had thought
Rheumatoid Arthritis Breakthrough
piggy submitted, created time 1 week 1 day (www.sciencedaily.com)
Rheumatoid arthritis is a painful, inflammatory type of arthritis that occurs when the body's immune system attacks itself. A new article reports a breakthrough in the understanding of how autoimmune responses can be controlled, offering a promising new strategy for therapy development for rheumatoid arthritis.
Normally, immune cells develop to recognise foreign material – antigens; including bacteria - so that they can activate a response against them. Immune cells that would respond to 'self' and therefore attack the body's own cells are usually destroyed during development
How Eating Red Meat Can Spur Cancer Progression: New Mechanism Identified
piggy submitted, created time 1 week 9 hours (www.sciencedaily.com)
Researchers at the University of California, San Diego School of Medicine, led by Ajit Varki, M.D., have shown a new mechanism for how human consumption of red meat and milk products could contribute to the increased risk of cancerous tumors.
Their findings, which suggest that inflammation resulting from a molecule introduced through consumption of these foods could promote tumor growth, are published online this week in advance of print publication in the Proceedings of the National Academy of Sciences (PNAS)
HIV vaccine failure explained?

Researchers have suggested that an experimental vaccine against AIDS might have failed in part because it made some people's immune cells more vulnerable to HIV infection.
Key Gene May Be Crucial to Production of Thymus and Disease-Fighting T-cells

This research provides the first evidence that a key gene may be crucial to maintaining the production of the thymus and its disease-fighting T-cells after an animal’s birth.
New Therapy Could Transform Arthritis Treatment

New understanding about how to control autoimmune responses offers promise in efforts to develop treatments for rheumatoid arthritis (RA), British researchers say.
