Defects in tissue trigger disease-like transformation of cells

Homeowners know that one little termite can lead to big problems: while termites are efficient at gnawing away at wood, they can do even more damage if the wood is already broken or has another defect. Mechanical engineers at Washington University in St. Louis have found the same effect in […]

Brain cancer vaccine effective in some patients

Most people with the deadly brain cancer glioblastoma die less than 18 months after diagnosis. But a multicenter clinical trial of a personalized vaccine that targets the aggressive cancer has indicated improved survival rates for such patients. The study appears in the Journal of Translational Medicine. The phase three clinical […]

Drugs that suppress immune system may protect against Parkinson’s

People who take drugs that suppress the immune system are less likely to develop Parkinson’s disease, according to a study from Washington University School of Medicine in St. Louis. The findings, published in Annals of Clinical and Translational Neurology, suggest that a person’s own immune system helps nudge him or […]

UVA researchers develop new technology to manage cancer pain

As cancer patients become increasingly ill toward the end of their lives, their pain often intensifies and increases in frequency. This is distressing not only to the patient, but also to the patient’s caregivers, often a spouse or partner. Effectively managing that pain with medications and other therapies is of […]

Study reveals phosphorous-containing lipid in membrane activates cell proliferation

Researchers at the University of Tokyo revealed that a phosphorous-containting lipid in the membrane plays a critical role in activating a protein involved in the transcription of genes regulating cell proliferation. This research outcome points to new drug targets for malignant cancer cells where this signaling pathway is involved. The […]

Neuroscientists discover roles of gene linked to Alzheimer’s

People with a gene variant called APOE4 have a higher risk of developing late-onset Alzheimer’s disease: APOE4 is three times more common among Alzheimer’s patients than it is among the general population. However, little is known about why this version of the APOE gene, which is normally involved in metabolism […]

Memory processes depend on protein ‘off-switch’ – could lead to new Alzheimer’s treatments

Memory, learning and cognitive flexibility depend on a protein 'off-switch' in the brain, according to a breakthrough discovery made by an international research collaboration co-led by the University of Warwick. This new knowledge could enable us to better understand and combat neurological diseases which inhibit memory, such as Alzheimer's. Dr […]

How the body balances its immune system

In your body, blood stem cells produce approximately 10 billion new white blood cells, which are also known as immune cells, each day. Even more remarkably, if some of these blood stem cells fail to do their part, other blood stem cells pick up the slack and overproduce whichever specific […]
