Diversity of HLA genotypes in humans is shaped to a significant degree by pathogens

The great physical diversity that evolution has forged in human beings is in evidence wherever we look, but the genes exhibiting the greatest diversity at the DNA level happen to function in a wholly invisible process: immunity. Genes encoding the Human Leukocyte Antigen (HLA) proteins are among the most diverse in the human genome, and scientists have proposed a number of hypotheses to explain why.

Research findings suggest new treatment strategies for patients with cystic fibrosis

Cells sent to fight infections in the lungs of cystic fibrosis patients actually enhance the development of permanent bacterial infections, according to researchers at National Jewish Medical and Research Center.

Chemo combo increases breast cancer survival

A new Spanish study has found that a combination of chemotherapy drugs can increase the five-year survival rate of women with metastatic, node-positive breast cancer by 7 percent.

Leprosy microbes lead scientists to immune discovery

With the unusual opportunity that human leprosy infections provide for study of human immune responses, scientists have discovered how the body's early warning system prompts a rapid immune response by two separate armies of defensive cells.

Cyclophosphamide may be a possible therapy for scleroderma

A drug that suppresses the immune system and reduces inflammation has been shown to be effective in treating lung disease associated with the devastating connective tissue disease scleroderma, according to results presented at the American Thoracic Society International Conference on May 23.

Anti-inflammatory protein annexin 1 may protect patients from the detrimental effects of severe inflammatory response syndrome

Severe inflammatory response syndrome, or SIRS, occurs when the body's response to an overwhelming infection becomes uncontrolled. The very immune response meant to clear the pathogen and its toxins actually causes damage to the host's own tissues when it goes into overdrive, releasing too many immune signals.

Routine, inexpensive blood test sharpens heart disease risk predictions

Routine measurements of white blood cell counts that provide a ratio of neutrophils to lymphocytes may offer a simple and low-cost way to refine predictions of heart attack or death, according to a new study in the May 17, 2005, issue of the Journal of the American College of Cardiology.

Zevalin safe and effective for non-Hogdkin's lymphoma patients

According to a University of Pittsburgh Medical Center (UPMC) study, patients with advanced non-Hodgkin's lymphoma (NHL) previously treated with chemotherapy and adult stem cell transplantation can safely tolerate Zevalin (ibritumomab tiuxetan), a radiolabeled monoclonal antibody that targets radiation directly to a tumor.

Breast cancer chemotherapy regimen associated with life-threatening complications

The chemotherapy regimen of doxorubicin plus docetaxel, used to treat breast cancer in a clinical trial, was associated with an increased risk of serious complications, resulting in the premature termination of the trial, according to a study in the May 18 issue of JAMA.

Lower doses of chemo just as effective in childhood cancers

In the latest research into treating a common childhood cancer, paediatric oncologist Allen Chauvenet, is optimistic that the long-term side effects that survivors experience as they grow into adulthood can be reduced.

SU11248 drug show promise against neuroendocrine tumors-stubborn cancers that respond poorly to chemotherapy

A unique, targeted anti-cancer drug appears to show promise against neuroendocrine tumors-stubborn cancers that have traditionally responded poorly to chemotherapy, according to research findings announced at the 2005 Annual Meeting of the American Society of Clinical Oncology (ASCO).

Taxotere shows significant survival benefit in the treatment of advanced gastric cancer

Final results from the largest international study in the treatment of advanced stomach cancer, also known as gastric cancer, demonstrated that patients who received a Taxotere (docetaxel) Injection Concentrate-based chemotherapy regimen (Taxotere, cisplatin and 5-fluorouracil) had significantly improved overall survival rates compared to patients who received a standard treatment (cisplatin and 5- fluorouracil).

New predictor for blood transplant success

The success of blood stem cell transplants used to treat diseases such as leukemia, Hodgkin’s lymphoma and aplastic anemia may soon become more predictable, thanks to a discovery made by researchers at the University of British Columbia.

Laboratory model of immune system overcomes ethical constraints on studies of hematopoietic stem cells in humans

Scientists at St. Jude Children’s Research Hospital have joined with colleagues at several other institutions to develop a laboratory model of the human immune system. This model will allow scientists to study ways for improving the results of hematopoietic stem cell (HSC) transplantation without putting patients at risk.

Neutrophils dictate whether our immune system will permit or prevent bacterial infections

New research on a bacterium that can survive encounters with specific immune system cells has strengthened scientists' belief that these plentiful white blood cells, known as neutrophils, dictate whether our immune system will permit or prevent bacterial infections.

Vaccine developed at Rockefeller University boosts natural killer T cells in patients with cancer

A new vaccine designed at The Rockefeller University boosted a type of fast-responding immune system cell called the natural killer T (NKT) cell in patients with advanced cancer. The study surprised researchers by revealing the ability of these NKT cells to spur other, slower-responding immune cells to go to work.

New drug may help treat certain forms of leukemia

A new experimental drug may be effective against a certain form of leukemia resistant to current treatments, research at UT Southwestern Medical Center shows.

Specific genes play key role in the of regulation of human-blood stem cells

This work is the first to validate gene expression analysis in human stem cells with functional experiments. The findings also suggest that changes in the expression of genes associated with universal cell signaling pathways can have a substantial impact on human stem cell behavior.

New prognostic markers help identify risk of relapse

A recently completed clinical study has found new prognostic markers that may help clinicians identify those children with leukaemia who are at high risk of relapse and are most in need of intensified treatment to improve their chance of survival.

Stress can give the immune system a beneficial boost

New research in mice provides more evidence that a brief bout of stress can give the immune system a beneficial boost – under certain conditions.
