Scripps research scientists solve structure of a critical innate immune system protein

...defense starting with the unleashing of an army of white blood cells, like macrophages, which engulf and destroy pathogens. The macrophages also fight the pathogens by producing large amounts of chemicals that induce inflammation and help the body clear the infection. One of the components of the innate i...

Male Combat Veterans Rank High In Heart Disease Risk

... (NHLBI), the LCSES study examined 5,368 black and white men who participated in the larger Atherosclerosis Risk in Communities study. White males represented 80 percent of this study population and black males, 20 percent. The men were 44 to 66 years old during the initial interviews from 1987-89. Combat...

Bacteria use host's immune response to their competitive advantage

...imulates the immune system to send out specialized white blood cells that attack its competitor, Streptococcus pneumoniae--a leading cause of pneumonia. "It is striking that the host's response can so completely eliminate the competitor," says Weiser. The findings also demonstrate how antibiotics and vacc...

Hepatitis C responds best to combo of ribavirin and interferon, study concludes

...tion therapy patients included a reduced number of white blood cells; skin disorders such as dry skin and rash; stomach complaints such as lack of appetite, nausea and indigestion; infections; insomnia; difficulty breathing, cough and fatigue. "The beneficial effect of adding ribavirin to interferon is no...

HIV Therapy Greatly Extends Life of Key T Cells, Scientists Find

...he progressive loss of CD4+ T cells (a key type of white blood cell) and the subsequent decline in the infected person’s ability to fend off disease. NIH clinical investigators pioneered the experimental use of IL-2 in HIV therapy to help boost the immune systems of people with HIV infection. Produced natu...

New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

... and eventually kills them. Early in this process, white blood cells called T lymphocytes infiltrate the islets of the pancreas (an inflammatory condition known as insulitis), causing the blood vessels to become leaky. Over time, this infiltration of lymphocytes destroys the beta cells, leading to high blo...

Why do aneurysms form? New studies suggest leading role for white blood cells

...ion, U-M researchers report that a certain type of white blood cell called a neutrophil appears to be crucial to AAA formation. Neutrophils are the "first responders" of the body's immune system, appearing rapidly on the scene of an infection or injury to an area of tissue, and sounding the alarm to summo...

New technique could alter field of mouse genetics

...ein and an enzyme that changes the coat color of a white mouse to grey or black. The transposon acts as a genetic beacon, so researchers can easily track its location without having to sequence the entire genome, as can happen with the chemical mutagen technique. In three months, the two graduate students...

Scavenger cells could be key to treating HIV-related dementia
