Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Double-barreled immune cell approach for neuroblastoma

Adding an artificial tumor-specific receptor to immune system cells called T-lymphocytes that target a particular virus extended and improved the cells' ability to fight a form of childhood cancer called neuroblastoma, said researchers form Baylor College of Medicine and Texas Children's Hospital in a report that appears online in the journal Nature Medicine.

Substance tackles skin cancer with two-pronged attack

By playing it safe and using a two-pronged attack, a novel designer molecule fights malignant melanoma. It was created and tested by an international team of researchers led by the University of Bonn.

Bacteria can directly cause human blood and plasma to clot

Bacteria can directly cause human blood and plasma to clot - a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research at the University of Chicago, National Institute of Allergy and Infectious Diseases, and Institut Pasteur in Paris. Their findings will be published online Nov. 2 in Nature Chemical Biology.

Important steps towards the development of a human vaccine against malaria

Every day 2,000 children die from malaria in Africa alone. The infection is transmitted from human to human by biting mosquitoes and remains one of the world's most devastating diseases. Despite many years of effort a vaccine is still not available but is urgently needed, if we are to make an impact on this enormous problem.

Vigorous exercise protects against breast cancer

Normal-weight women who carry out lots of vigorous exercise are approximately 30% less likely to develop breast cancer than those who don't exercise vigorously.

Good genes behaving badly behind type 1 diabetes

Investigators combing the genome in the hope of finding genetic variants responsible for triggering early-onset diabetes may be looking in the wrong place, new research at the Stanford University School of Medicine suggests.

Cancer requires support from immune system to develop, researchers report

Tumors that grow around nerves in a rare genetic disease need cooperation from cells from the immune system in order to grow, reports a team of scientists, including researchers from UT Southwestern Medical Center.

Drinking milk to ease milk allergy?

Giving children with milk allergies increasingly higher doses of milk over time may ease, and even help them completely overcome, their allergic reactions, according to the results of a study led by the Johns Hopkins Children's Center and conducted jointly with Duke University.

Blood stored for 29 days or more linked to infection

Blood stored for 29 days or more, nearly 2 weeks less than the current standard for blood storage, is associated with a higher infection rate in patients who received transfusions with the blood.

Gene against bacterial attack unravelled

Dutch researcher Joost Wiersinga from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei. The research is the next step towards a vaccine against this bacterium suitable for bioweapons.

New tuberculosis vaccine safer, more effective than BCG vaccine for HIV-positive people

A new tuberculosis vaccine could be safer and more effective than the currently available BCG vaccine, particularly for HIV-positive people, according to a study to be published in the November issue of Infection and Immunity, IANS/Times of India reports (IANS/Times of India, 10/24).

Cholesterol-lowering statins associated with lower risk of death from pneumonia

Individuals who take cholesterol-lowering statins before being hospitalized with pneumonia appear less likely to die within 90 days afterward, according to a report in the October 27 issue of Archives of Internal Medicine.

In mice, anxiety is linked to immune system

In the first study ever to genetically link the immune system to normal behavior, scientists at Rockefeller and Columbia universities show that mast cells, known as the pharmacologic bombshells of the immune system, directly influence how mice respond to stressful situations.

The sooner the better when it comes to HIV/AIDS treatment

New research into HIV/AIDS therapy has found that starting treatment with drugs for the AIDS virus may be better sooner than later as victims are more than 70% less likely to die when they started taking cocktails of HIV drugs earlier than currently recommended.

Warnings in NSW of whooping cough outbreak

An outbreak of whooping cough in New South Wales is causing some concern - the NSW Health Department says infection rates have soared from 2,000 cases last year, to 3,800 cases this year, and the increase is more so in some areas.

Feeling itchy? it may be stress!

German and Canadian researchers are suggesting that stress may make people itch - they say stress possibly activates immune cells in the skin and inflames it.

Human rhinovirus found to manipulate genes

Sneezing, runny nose and chills? You might blame the human rhinovirus (HRV), which causes 30 to 50 percent of common colds. But in reality, it's not the virus itself but HRV's ability to manipulate your genes that is the true cause of some of the most annoying cold symptoms.
