Regular exercise boosts immune system in older men

As it turns out, judging by the reaction strength of their immune system to an unknown, but harmless, protein antigen, it’s possible for men over 70 to mount an immune response similar to that produced by much younger men -- if they get regular moderate physical activity of about six hours a week.

Researchers find how cancers, particularly lymphomas, develop and might be prevented

Researchers at Children's Hospital Boston have begun unraveling the mystery of how B lymphocytes - key infection-fighting cells in the body - are able to create many different kinds of specialized antibodies through selective gene mutations, while being protected from random mutations that could give rise to cancers.

Surprise finding could lead to hepatitis C vaccine

New research from the University of New South Wales shows some people may repeatedly be able to clear hepatitis C virus from their bodies, without any biological traces of the potentially serious infection.

New information about how HIV evades eradication from the body

Researchers at the National Cancer Institute, have discovered new information about how human immunodeficiency virus (HIV), the virus that causes acquired immune deficiency (AIDS), possibly evades eradication from the body.

Effect of prebiotic and probiotic foods on health

A group of researchers at the Public University of Navarre, led by Senior Lecturer in Zoology, Elena Urdaneta Artola, have studied both the mechanisms whereby foodstuffs known as functional act at a gastrointestinal level as well as their possible beneficial effects on the health of individuals.

Antibodies produced by shark immune systems could be used to detect human pathogens

A recent discovery shows that antibodies produced by shark immune systems could be used to detect a range of human pathogens some of which have the potential to be used as biological warfare agents.

Large percentage of child deaths related to malaria are attributable to undernutrition and deficiencies

A large percentage of child deaths related to malaria are attributable to undernutrition and deficiencies of vitamin A, zinc, iron and folate, according to a new report by researchers with the Johns Hopkins Bloomberg School of Public Health.

Nucleic acid-amplification testing has improved the safety of the nation's blood supply

State-of-the-art testing systems to screen donated blood have improved the safety of the nation's blood supply by preventing the transmission of potentially deadly viruses, according to a new study funded by the National Heart, Lung, and Blood Institute.

Researchers find important gene for lupus

Researchers at the University of Minnesota have identified, for the first time, a gene variation associated with systemic lupus erythematosus (SLE), a potentially fatal disease which causes the body's defence system to attack itself.

Research will lead to better treatments for mastocytosis

Tens of millions of people know what it's like to suffer the seasonal torment of allergies, when just a whiff of pollen, mold or dust can set off a chain reaction in the body that causes sniffling, sneezing and coughing.

Organ transplant recipients infected with West Nile virus develop more severe neurological illness

West Nile virus is an infection which in the last three years has had a significant impact in the United States. The virus is spread from birds to humans via mosquito bites. Symptoms include headache, fever and disorientation, and the disease can cause serious illness in a small percentage of infected people.

Contract for the production of an investigational vaccine based on an H9N2 strain of avian influenza virus

In 1999 and 2003, an H9N2 influenza strain caused illness in three people in Hong Kong. Scientists are concerned about H9N2 and other emerging types of avian influenza viruses because as they spread—most commonly through poultry—they continually mutate, increasing chances that they may infect humans, evade the body’s immune response and become more lethal.

Scientists have successfully filmed individual cells migrating within a functioning lymph node

The researchers hope to gain a deeper understanding of how our immune system functions from their detailed study of lymph node processes.

Friendly bacteria the key to ulcerative colitis treatment

Affecting an estimated fifty thousand people in the UK, with a particularly high incidence rate in north east Scotland, ulcerative colitis is an acute and chronic disease that causes inflammation and sores, called ulcers, in the lining of the large bowel.
