Optimists don't always fare better than pessimists in their immunologic response to stress

The difference seems to be based on the degree of stress facing the optimist and the degree to which a pessimist avoids the problem, according to an article in the current issue of the journal Brain, Behavior, and Immunity by Suzanne Segerstrom, Ph.D., of the University of Kentucky.

Molecule called Smad7 may open doors to future treatments in pancreatic and other forms of cancer

Making new strides in their ongoing effort to understand mechanisms behind the relentless growth of cancer cells, researchers at Dartmouth Medical School have found a promising key that may open doors to future treatments in pancreatic and other forms of cancer.

Diversity of HLA genotypes in humans is shaped to a significant degree by pathogens

The great physical diversity that evolution has forged in human beings is in evidence wherever we look, but the genes exhibiting the greatest diversity at the DNA level happen to function in a wholly invisible process: immunity. Genes encoding the Human Leukocyte Antigen (HLA) proteins are among the most diverse in the human genome, and scientists have proposed a number of hypotheses to explain why.

Whooping cough vaccine may be introduced in New Zealand

The New Zealand's Ministry of Health has confirmed, as a whooping cough epidemic continues to sweep the country, that a new vaccine to control the spread of whooping cough may be introduced next year.

New vaccine against whooping cough is effective in teens and adults

The Journal of the American Medical Association (JAMA) has announced that a study to be published in the June 22/29 issue found that a new vaccine against whooping cough is effective in teens and adults, carriers of the contagious respiratory disease so dangerous to infants.

Stronger version of chickenpox vaccine cuts incidence and severity of shingles in older adults

In one of the largest adult vaccine clinical trials ever, researchers have found that an experimental vaccine against shingles (zoster vaccine) prevented about half of cases of shingles--a painful nerve and skin infection--and dramatically reduced its severity and complications in vaccinated persons who got the disease. The findings appear in the June 2 issue of The New England Journal of Medicine.

Blood abnormality, sickle cell trait, gives added protection to children from malaria

The blood cell abnormality, sickle cell trait, gives an increasing amount of protection against malaria as young children grow during their first ten years of life, new research has revealed.

Sickle cell protects against malari

In this month's issue of the open access journal PLoS Medicine, Dr. Thomas N. Williams and colleagues from Kilifi, Kenya, show that the protection against malaria given by carrying the gene for sickle cell haemoglobin may involve the immune system.

Leprosy microbes lead scientists to immune discovery

With the unusual opportunity that human leprosy infections provide for study of human immune responses, scientists have discovered how the body's early warning system prompts a rapid immune response by two separate armies of defensive cells.

Is winter flu worse because of exercise-induced 'window of susceptibility'?

When you exercise or work outside in winter, that dry feeling at the back of your throat indicates the cold air has irritated your throat. Racehorses share a similar experience: exercising in below-freezing air causes mild airway injury.

Stimulating innate immunity helps ease Crohn's disease symptoms

Like throwing oil on a fire or prescribing a high cholesterol diet for heart patients, gastroenterologists traditionally have believed that it would not be a good idea to stoke up the body's immune system to treat Crohn's disease.

Human cells can silence an essential part of HIV's genetic make-up

For the first time, scientists have shown that humans use an immune defense process common in plants and invertebrates to battle a virus.

New combination vaccine effective against plague

Plague, a bacterium that ravaged Europe in the Middle Ages and is today one of the most feared potential agents of bio-terrorism, may have met its match, according to Wake Forest University School of Medicine scientists.

Nutrition gene key in regulating immune system

A gene that signals a yeast cell to make bread rise and mice to eat a better diet also helps selectively silence the immune system, researchers have found.

Scientists have uncovered a new method the immune system uses to label foreign invaders as targets to be attacked

Researchers showed that the immune system can brand foreign proteins by chemically modifying their structure, and that these modifications increased the chances that cells known as lymphocytes would recognize the trespassers and attack them.

Intralesional immunotherapy for common warts is effective and safe

Injection of skin test antigens (preparations used in skin tests for immunity) into warts appears to stimulate the immune system and successfully treat the injected wart and also helps to treat distant non-injected warts, according to a study in the May issue of Archives of Dermatology.
