Violent sex acts boost insect's immunity system
12-04-2007 · EurekAlert!
The long-held idea that only vertebrates have sophisticated adaptive immune systems that can protect them for life against many pathogens after being infected by them just once has been revised in recent years. It turns out that many insects also have a form of immune memory that protects them against reinvasion by a pathogen they have previously encountered.

Security loophole found in Windows operating system
11-12-2007 · EurekAlert!
A group of researchers headed by Dr. Benny Pinkas from the department of computer science at the University of Haifa succeeded in finding a security vulnerability in Microsoft's Windows 2000 operating system. The significance of the loophole: e-mails, passwords, credit card numbers, if they were typed into the computer, and actually all correspondence that emanated from a computer using Windows 2000 is susceptible to tracking.

Molecule that destroys bone also protects it, new research shows
05-08-2007 · EurekAlert!
An immune system component that is a primary cause of bone destruction and inflammation in autoimmune diseases such as rheumatoid arthritis actually protects bone in the oral cavity from infectious pathogens that play a major role in periodontal disease in humans, research at the University at Buffalo has shown.

Intravenous gene therapy protects normal tissue of mice during whole-body radiation
10-28-2007 · EurekAlert!
Gene therapy administered intravenously could be used as an agent to protect vital organs and tissues from the effects of ionizing radiation in the event of large-scale exposure from a radiological or nuclear bomb. In the University of Pittsburgh study, mice were used to test the protective effects of manganese superoxide dismutase plasmid liposome gene therapy on the bone marrow during whole-body irradiation.

Aerosol launches immune response in lungs to wipe out lethal infections
12-03-2007 · EurekAlert!
An inhaled immune system stimulant protects mice against lethal pneumococcal pneumonia and other deadly bacterial, viral and fungal infections of the lungs, a research team led by scientists at the University of Texas M. D. Anderson Cancer Center reports at a major scientific meeting.

'Nondanger' signal lowers immune reactions
05-15-2007 · EurekAlert!
Rheumatology researchers have discovered that a well-known cell receptor sends a signal to dampen the immune system. While not having an immediate application to treating disease, the finding raises the possibility that by targeting that receptor, physicians could stimulate a "nondanger" signal to rein in overzealous human immune responses. Controlling those responses could potentially protect transplant patients from rejection episodes or could relieve symptoms of autoimmune diseases such as rheumatoid arthritis and lupus.

Newly found sensing system enables certain bacteria to resist human immune defenses
06-07-2007 · EurekAlert!
Researchers at the National Institute of Allergy and Infectious Diseases, a component of the National Institutes of Health, have discovered a survival mechanism in a common type of bacteria that can cause illness. The mechanism lets the bacteria protect itself by warding off attacks from antimicrobial peptides, which are defense molecules sent by the body to kill bacteria.

UVA researchers explain cell response to skin-damaging UV rays
10-01-2007 · EurekAlert!
Researchers at the University of Virginia Health System have published a new study that helps scientists around the world expand the body of knowledge on how cells protect themselves (or not) from DNA damage caused by UV rays. Their study reveals part of a 'simple switch' mechanism inside cells, triggered by UV exposure from the sun, that helps our cells survive and thrive after being exposed. This mechanism involves an unanticipated connection between several proteins in the cell, the researchers discovered.

Mice help researchers understand chlamydia
10-29-2007 · EurekAlert!
Genetically engineered mice may hold the key to helping scientists from Queensland University of Technology and Harvard hasten the development of a vaccine to protect adolescent girls against the most common sexually transmitted disease, chlamydia. Dr Michael Starnbach from Harvard Medical School is in Australia to work with QUT on a joint research project using a "mouse model" to study how the immune system responds to infections such as chlamydia.
