NCI Researchers Confirm the Effectiveness of Immunotherapy Approach to Treating Melanoma

...oved from the patient, activated or re-educated to attack the tumor, then reintroduced into the patient. The..., a type of white blood cell in the blood that can attack tumors, were separated from other parts of the blood. Next, patients were treated for two days with ...

Immune system's distress signal tells bacteria when to strike back

... when its host is most vulnerable and to launch an attack before the weakened host can muster its defenses. In the 29 July 2005 issue of Science, the researchers show how this lethal organism detects interferon-gamma, a chemical messenger the immune system uses to coordinate its efforts to get rid of bacte...

Enzyme's newly discovered role may make it target for arthritis treatment

...cals that bring in secondary waves of other immune attack cells. "The contributions of the neutrophil weren't always appreciated by scientists," Pham notes. "When patients come to their doctors with arthritis symptoms, the inflammation typically is so well-established that neutrophils are no longer the pre...

Stem cell therapy successfully treats heart attack in animals

...s, possibly leading to a first-ever cure for heart attack in humans," he says. "If a treatment can be found for the damage done by a heart attack to heart muscle, then there is the potential to forestall the serious complications that traditional...

Morphine for Chest Pain Increases Death Risk

While patients hospitalized for a heart attack have long been treated with morphine to relieve ch...a and outcomes of more than 57,000 high-risk heart attack patients -- 29.8 percent of whom received morphine within the first 24 hours of hospitalization -- t...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...nce proteins to defend themselves against pathogen attack by initiating a defense response," Holt said. "The proteins RAR1, HSP90 and SGT1 were previously thought to work together to help resistance proteins in this function. To our surprise, we found that SGT1 can actually work against, or antagonize, the ...

Enlisting genomics to understand flu evolution

... better predictions about which viral strains will attack during upcoming flu seasons and design more effective flu vaccines. In the first large-scale effort to sequence the flu genome, Edward Holmes, David Lipman, and colleagues examined the genomes of 156 influenza A viruses (serotype H3N2) collected by ...

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

...rigger the immune system's multi-stage biochemical attack on the pathogens. Humans have at least 10 different TLRs, each of which recognizes a specific subset of antigens. For instance, TLR4 recognizes lipopolysaccharide, a chemical component of the cell walls of certain bacteria like Neisseria meningitide...

Purdue scientists may have found key to halting spinal cord damage

...g acrolein will allow doctors to stop the chemical attack cycle as well, adding to the number of treatment methods available." The center was established in 1987 both to develop and to test promising methods of treatment for spinal cord injuries. The center uses its close affiliation with the Department of...

New insights into how Huntington's disease attacks the brain

...der that usually strikes in mid-life, but can also attack the elderly and children as young as 2. Slowly depriving a person of their ability to think, speak, walk and swallow, the disease robs the person of their independence, leading to death within 10 to 25 years. Every carrier of the HD gene mutation wi...

Improving the potential of cancer vaccines

...ause the immune system is unchecked and goes on to attack the body's own tissues. His group previously reported the existence of tumor-specific Treg cells at tumor sites. "Thus, the tumor cells use these Treg cells to protect themselves," said Wang. "In fact, tumor cells can actively recruit and activate t...

Bacteria use host's immune response to their competitive advantage

...tem 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 vaccines that target one mic...

New type of rejection blocker protects kidneys after transplant

...-stimulatory signal is required before the T-cells attack the kidney. By blocking this second signal, belatacept prevents destruction of the kidney without suppressing the immune system's response to viruses and other pathogens. Belatacept is based on research into the molecular basis of immune tolerance. ...
