Cancer stem-cell model tested by University of Michigan researchers

One of the most promising new ideas about the causes of cancer, known as the cancer stem-cell model, must be reassessed because it is based largely on evidence from a laboratory test that is surprisingly flawed when applied to some cancers, University of Michigan researchers have concluded.

Dieters could have a harder time fighting flu

In a study published in the November issue of the Journal of Nutrition, Gardner showed that mice with a calorie-restricted diet were more likely to die during the first few days of infection than mice with a normal diet. Caloric restriction is the practice of reducing the intake of calories to 40 percent of a normal diet, while maintaining adequate vitamins and minerals.

A third of miscarriages preventable with steroid treatment

A conference in Liverpool in the UK has heard how some women who have suffered repeated miscarriages or failed IVF treatments may be helped to become mothers by taking a course of steroids.

New role for Natural Killer cells

Scientists at the University of York have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer.

The body's fight with cervical cancer

The virus responsible for most cases of cervical cancer has a serious weakness which may provide hope for new treatments for the disease.

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.

Immune system disorder may be the cause of unexplained infertility

It's been a topic on Sex and the City and was rumored to be a problem for a popular sitcom star when she and her husband were trying to conceive.

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.

Link between common lifestyle factors, immune system and cancer

The immune system is fickle, and easily influenced by more than just viruses and bacteria. It can be swayed by the seemingly unexpected, such as by what we eat, for example, and affected by surprising sources.

New technique allows partial-match cell transplants for children with most resistant leukemia

Clinicians at St. Jude Children's Research Hospital have successfully demonstrated an improved technique for blood stem cell transplantations in children that shows promise for those most likely to fail standard treatment for leukemia.
