Researchers uncover how HIV causes abnormalities in antibody-producing cells

HIV wreaks much of its damage by targeting the “orchestra conductor” of the immune system, a key class of T cells—CD4+ T cells—whose destructive relationship with HIV has been well-studied by AIDS researchers.

Pig tissue may help reduce the damage and disability of stroke

A tiny capsule containing tissue that secretes a cocktail of brain-nourishing neurotrophic factors may one day help reduce the damage and disability of stroke, according to research published in the September issue of Stroke.

Sinovac completes dosing in phase 1 human clinical testing of SARS vaccine

Sinovac Biotech Ltd. has announced that all 36 subjects of the Phase I human clinical trial for its inactivated SARS vaccine have now been vaccinated with two doses of either SARS vaccine or placebo.

Researchers unravel genetic makeup of ticks to tackle disease

Ticks as small as a freckle can transmit a number of illnesses for which there is no vaccine and, in some cases, no cure. These creatures even could become bioterrorism weapons.

Counseling for breast cancer patients means healthier diets, reduced smoking and stronger immune systems

Regular psychological counseling for breast cancer patients may do more than just lower their stress and anxiety. A new study says the right kind of intervention can also mean healthier diets, reduced smoking, and most surprising of all – a stronger immune system.

Parental human leukocyte antigen genes linked to preterm delivery

The transmission of Human Leukocyte Antigen (HLA) genes may play a significant role in the risk of preterm delivery, according to a study in the September issue of Obstetrics and Gynecology.

Interim data from human clinical trials of two AIDS vaccine candidates, named DNA.HIVA and MVA.HIVA

The interim data, from 205 volunteers in clinical trials in Kenya, Uganda and the United Kingdom, show that DNA.HIVA and MVA.HIVA are generally safe and well tolerated. However, the candidates’ ability to elicit an anti-HIV cell-mediated immune response is poor, using currently accepted measures of immune response.

Common enzyme acts as a natural brake to prevent potentially deadly runaway inflammation

An enzyme found in nearly all animal and human cells acts as a natural brake to prevent potentially deadly runaway inflammation, UCSF scientists have discovered.

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.

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.

Stem cell research may one day help cerebral palsy

Natural chemicals that assist healing may one day help transplanted adult stem cells integrate into an injured brain, helping children with cerebral palsy recover lost function, according to researchers at the Medical College of Georgia.

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.

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.

Revolutionary new test for identifying people infected with tuberculosis

The test – named T SPOT-TB – is designed to replace the century old skin test for TB, which is currently given to 600,000 UK schoolchildren every year. The test comes from discoveries made over the last 10 years at the University of Oxford by Dr Aljit Lalvani and collaborators at the Nuffield Department of Medicine.
