Preliminary experiments in a handful of people suggest that it might be possible to reverse Type 1 diabetes using an inexpensive vaccine to stop the immune system from attacking cells in the pancreas. Research in mice had already shown that the tuberculosis vaccine called BCG, prevents T cells from destroying insulin-secreting cells, allowing the pancreas to regenerate and begin producing insulin again, curing the disease. Now tests with very low doses of the vaccine in humans show transient increases in insulin production, researchers will report Sunday at a San Diego meeting of the American Diabetes Assn.

Being a younger sibling may mean more hand-me-downs and fewer baby photos than if you were lucky enough to be the blessed eldest child of the family. But here's a compensating benefit: You're less likely than the firstborn to suffer a food allergy --or, for that matter, the runny nose, itchy or irritated eyes and swelling that come with allergies to such triggers as dust, pollen and pet dander. That finding was presented this weekend in San Francisco at the annual meeting of the American Academy of Allergy, Asthma and Immunology ( AAAAI )

Doctors and infectious bacteria are locked in an arms race. In this ever-escalating battle, the bacteria evolve ways to avoid every drug humans throw at them. The conflict has intensified lately as more and more bacteria — particularly those lurking in hospitals — become able to resist nearly every antibiotic in our arsenal. "We throw thousands and thousands of antibiotics on bacteria," says Marcin Filutowicz, a microbiologist at the University of Wisconsin in Madison.

Devotees of massage therapy know it's relaxing and feels good. But massage may also be an effective tool for maintaining good health. Researchers from Cedars-Sinai Medical Center reported this week that a single massage produced measurable changes in the immune system and endocrine system of healthy adults. The researchers, led by Dr. Mark Rapaport, studied 29 healthy adults who received a 45-minute Swedish massage and 24 healthy adults who had a 45-minute session of light touch massage, a much milder exercise that served as a comparison to the more vigorous Swedish massage.

Pharmacy chain CVS Caremark Corp. will repay about $2.8 million to consumers who bought a dietary supplement that was falsely marketed as a product that could prevent illness, the Federal Trade Commission said Tuesday. CVS touted its AirShield tablets and powders as a way to fight off the flu and boost the immune system, but there is no evidence that the products could do either, the commission said. As part of the $2.78-million settlement, CVS agreed to no longer make those claims, and it has changed the products' packaging.

If you want to live longer -- avoid heart disease, Alzheimer's disease and cancer -- then pick and choose your foods with care to quiet down parts of your immune system. That's the principle promoted by the founders and followers of anti-inflammatory diets, designed to reduce chronic inflammation in the body. Dozens of books filled with diets and recipes have flooded the market in the last few years, including popular ones by dermatologist Dr. Nicholas Perricone and Zone Diet creator Barry Sears.

Doctors have overcome 30 years of false starts and found success with a new way to fight cancer: using the body's natural defender, the immune system. The approach is called a cancer vaccine, although it treats the disease rather than prevents it. Researchers at a cancer conference in Orlando said Sunday that one such vaccine kept a common form of lymphoma from worsening for more than a year.

HIV, the virus that causes AIDS, is one of the fastest-evolving entities known. That's why no one has yet been able to come up with a vaccine: The virus mutates so rapidly that what works today in one person may not work tomorrow or in others. A study published Wednesday in the journal Nature confirms that dizzying pace of evolution on a global scale.

Heart transplant patients are as much as 25% more likely to survive if the sex of the donor is the same as the patient's, researchers said Wednesday. The results surprised experts because, for most types of transplants, sex differences are irrelevant as long as a good immunocompatability is achieved.

Most deaths in the 1918 influenza pandemic were due not to the virus alone but to common bacterial infections that took advantage of victims' weakened immune systems, according to two new studies that could change the nation's strategy against the next pandemic. "We have to realize that it isn't just antivirals that we need," said Dr. Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases and coauthor of one study. "We need to make sure that we're prepared to treat people with antibiotics," said Fauci, whose study will be released online this month by the Journal of Infectious Diseases.
