Specialized natural killer cells in human tonsils help protect against Epstein Barr virus

Tonsils are a source of sore throats and an excuse for ice cream. But they also provide an important protective service, their immune-cell-rich tissue acting as the body's first defense against the germs about to be swallowed or inhaled.

Immune cells can simultaneously stimulate and inhibit killer cell activity

Dendritic cells, which are responsible for teaching other immune cells to attack infected or mutated cells, face a dangerous predicament.

Breast cancer radiation does not affect women's immune system

A new study shows that neither of two commonly used radiation treatments for early-stage, node-negative breast cancer has any effect on a woman's immune system, even though women who receive five-day partial-breast radiation therapy (MammoSite brachytherapy) (PBRT) have improved energy and quality of life compared to women who undergo six weeks of whole-breast radiation therapy (WBRT).

Relationship between stress and breast cancer

Women diagnosed with metastatic breast cancer who have also endured previous traumatic or stressful events see their cancer recur nearly twice as fast as other women, according to a report by a University of Rochester Medical Center scientist.

Scientists shed new light on how antibodies fight HIV

By furthering scientists' understanding of the molecular mechanisms that separate the minority of successful HIV antibodies from the majority of ineffective antibodies, the work may have implications for future attempts to design an HIV vaccine.

New target for drugs to fight the HIV/AIDS virus

Researchers from Rome, Italy, describe a finding in the August 2007 print issue of The FASEB Journal that could lead to new drugs to fight the HIV/AIDS virus, as well as new vaccines to prevent infection.

Oncolytic viruses deliver a knockout punch to cancers

New scientific evidence is helping to build a compelling case for oncolytic viruses as a first-line and adjunctive treatment for many cancers.

Researchers discover genetic 'shut down' trigger in healthy immune cells

A fundamental genetic mechanism that shuts down an important gene in healthy immune system cells has been discovered that could one day lead to new therapies against infections, leukemia and other cancers.

Researchers identify immune dysfunction in melanoma patients

Researchers at the Stanford University School of Medicine have begun to shed light on why the human immune system isn't able to stop such cancers as melanoma, suggesting answers that could pave the way for better treatment of this often-fatal illness.

Novel method to expand the number of immune system "natural killer" cells from blood cells outside the body

Researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have devised a novel method to expand the number of immune system "natural killer (NK)" cells from blood cells outside the body.

Cetuximab improves survival and slows progression of colorectal cancer

Research presented at the 2007 Annual Meeting of the American Association for Cancer Research confirmed that there is now an effective treatment option for colorectal cancer patients for whom all other treatment options have been exhausted, cetuximab.

Children under stress develop more fevers

Children whose parents and families are under ongoing stress have more fevers with illness than other children. Published this month in the Archives of Pediatric and Adolescent Medicine, the study also shows the unanticipated conclusion that children's natural killer cell function, part of the body's innate immune system, increases under chronic stress, unlike adults, whose function is decreased.
