Vaccine shows promising results for early-stage breast cancer patients
- Details
- Category: Research
Deregulation and inhibition of the immune system contributes to cancer development. Many therapeutic strategies aim to re-stimulate the immune system to recognize cancer cells and target them for destruction. Researchers from Moffitt Cancer Center report that a dendritic cell vaccine that targets the HER2 protein on breast cancer cells is safe and effectively stimulates the immune system leading to regression of early-stage breast cancer.
Anti-aging therapies targeting senescent cells: Facts and fiction
- Details
- Category: Research
It's an exciting time to be an elderly mouse. Researchers believe that by removing senescent cells (cells with a persistent damage response), which naturally accumulate with age, senior rodents can regrow hair, run faster, and improve organ function. This strategy may bring us one step closer to the "fountain of youth," but it's important to be cautious and not hype, says researcher of aging Peter de Keizer of the Erasmus University Medical Center in the Netherlands.
Topical treatment activates immune system to clear precancerous skin lesions
- Details
- Category: Research
A combination of two FDA-approved drugs - a topical chemotherapy and an immune-system-activating compound - was able to rapidly clear actinic keratosis lesions from patients participating in a clinical trial. Standard treatment for this common skin condition, which can lead to the development of squamous cell carcinoma, takes up to a month and can elicit several unpleasant side effects.
Diabetes, heart disease, and back pain dominate US health care spending
- Details
- Category: Research
Just 20 conditions make up more than half of all spending on health care in the United States, according to a new comprehensive financial analysis that examines spending by diseases and injuries. The most expensive condition, diabetes, totaled $101 billion in diagnoses and treatments, growing 36 times faster than the cost of ischemic heart disease, the number-one cause of death, over the past 18 years.
New precision medicine tool helps optimize cancer treatment
- Details
- Category: Research
Columbia University Medical Center (CUMC) researchers have created a computational tool that can rapidly predict which genes are implicated in an individual's cancer and recommend treatments. It is among the most comprehensive tools of its kind, and the first that incorporates a user-friendly web interface that requires little knowledge of bioinformatics.
Commonly used drugs lead to more doctor's office, hospital and emergency department visits

Anticholinergic medications, a class of drugs very commonly used by older adults, are linked to an increased rate of emergency department and hospital utilization in the United States, according to an Indiana University Center for Aging Research, Indiana University Center for Health Innovation and Implementation Science, and Regenstrief Institute study of community-dwelling Americans age 65 and older.
Tuberculosis virulence factor identified, may be target for new drug
- Details
- Category: Research
Scientists have discovered the mechanism that hijacks the immune system's response to tuberculosis, revealing an important new drug target for the disease that kills more than 1 million people each year. Herman Sintim, Purdue University's Drug Discovery Professor of Chemistry, collaborated with scientists at Johns Hopkins University to determine how tuberculosis turns off a human cell's signal to mount an immune response to the bacteria.
