Survival mechanism of T lymphocytes uncovered

When an individual is challenged by a virus, a bacterium or any other infectious agent, several classes of white blood cells are being activated in order to fight the invasion.

BMI may serve as prognostic tool for advanced, aggressive breast cancers

Body Mass Index (BMI), the measure of a person's fat based on their height and weight, may be an effective prognostic tool for specific types of breast cancer, according to research from The University of Texas M. D. Anderson Cancer Center.

DNA detectives find genetic markers for lung cancers most likely to recur

Researchers at the Johns Hopkins Kimmel Cancer Center have uncovered clearly recognizable genetic alterations in tumors and tissue removed from patients with early-stage lung cancers that look like good predictors of which of these cancers are more likely to recur.

Nuclear protein SATB1 triggers aggressive breast cancer

SATB1 is a nuclear protein well known for its crucial role in regulating gene expression during the differentiation and activation of T cells, making it a key player in the immune system.

Survival rates for patients for with non-Hodgkin lymphoma improved over past decade

Five- and 10-year survival rates for patients with non-Hodgkin lymphoma appear to have increased from the 1990s to the early 21st century, according to a report in the March 10 issue of Archives of Internal Medicine.

PET/CT planning beneficial for head and neck cancer patients

Using a combination of positron emission tomography (PET) and computed tomography for radiation therapy treatment planning in head and neck carcinoma patients provides for excellent, local and regional disease control when compared to CT alone, according to a study in the March 1 issue of the International Journal for Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

Discovery of potential drug targets for sepsis

"We have identified a key connection of signaling pathways in the cascade of events leading to sepsis. This defines a crucial point where the immune system spirals out of control to cause severe sepsis and where there is an opportunity for therapeutic intervention," says Scripps Research Professor Wolfram Ruf, who led the research with his postdoctoral fellow Frank Niessen.

New blood biomarker accurately predicts spread of prostate cancer to regional lymph nodes

Researchers report finding a new blood biomarker that enables close to 98 percent accuracy in predicting the spread of prostate cancer to regional lymph nodes.

GeneSearch Breast Lymph Node Assay reduces recurrence of breast cancer

A new test that examines large sections of the sentinel lymph node for genes expressed by breast cancer could reduce the risk of recurrence and multiple surgeries, doctors say.

New discovery, immune cells confront viruses just inside of the lymph node

Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them. An improved understanding of how the immune system operates during a viral infection is critical to designing successful anti-virus vaccines.

Scientists focus on Epstein-Barr virus

Epstein-Barr virus (EBV) is a human-pathogenic virus which belongs to the herpes virus family.

Extra-hepatic manifestation of hepatitis C virus infection

In 1994, the team of Tchernev and Petrova from Alexandrovska Hospital in Sofia examined a female patient with liver cirrhosis caused by chronic Hepatitis C virus (HCV).

Researchers find cell protein that blocks HIV virus generation

UCLA researchers have found that a key protein in the body's dendritic cells can stop the virus that causes AIDS from "budding" part of the virus' life cycle that is crucial to its ability to replicate and infect other cells.

The link between combined HRT use and the risk of lobular breast cancers

Postmenopausal women who take combined estrogen/progestin hormone-replacement therapy for three years or more face a fourfold increased risk of developing various forms of lobular breast cancer, according to new findings by researchers at Fred Hutchinson Cancer Research Center.

Radical and partial nephrectomy for kidney cancers

A new Mayo Clinic study suggests that removing the entire kidney from younger patients with small kidney tumors may lead to decreased overall survival compared with an operation that removes the tumor but leaves the kidney intact.

Scientists use virus to wipe out cancer cells

Cancer Research UK scientists have used the immune system coupled with a virus found in horses and cattle, to hunt and purge cancer cells through the lymphatic system, a study reveals in Nature Medicine.

BRCA1 and BRCA2 gene mutations and breast cancer

Breast cancer risk varies widely among women who are carriers of the BRCA1 and BRCA2 mutations, according to a new study published in the January 9, 2008, issue of the Journal of the American Medical Association (JAMA).

High-energy ultrasound imaging produces clearer pictures of liver tumors

A high-energy form of ultrasound imaging developed by researchers at Duke University's Pratt School of Engineering produces pictures of liver tumors that are better than those made with traditional ultrasound, according to results of a clinical study.

Researchers train the immune system to deliver virus that destroys cancer in lab models

An international team of researchers led by Mayo Clinic have designed a technique that uses the body's own cells and a virus to destroy cancer cells that spread from primary tumors to other parts of the body through the lymphatic system.
