Genetic imbalance in immune system linked to biliary tract cancer

Patients with biliary tract cancer have altered genetic architecture in some immune system receptor systems. This has been shown by researchers at Karolinska Institutet in Sweden in a new study published in the journal Gastroenterology. It is hoped that the discovery will lead to new effective immunotherapy for these difficult […]

Cholesterol medication could invite diabetes, study suggests

A study of thousands of patients’ health records found that those who were prescribed cholesterol-lowering statins had at least double the risk of developing type 2 diabetes. The detailed analysis of health records and other data from patients in a private insurance plan in the Midwest provides a real-world picture […]

A better way to encapsulate islet cells for diabetes treatment

When medical devices are implanted in the body, the immune system often attacks them, producing scar tissue around the device. This buildup of tissue, known as fibrosis, can interfere with the device’s function. MIT researchers have now come up with a novel way to prevent fibrosis from occurring, by incorporating […]

New Therapy Targets Gut Bacteria to Prevent and Reverse Food Allergies

Study finds altered gut microbiota in infants with food allergy; oral therapy to replenish bacteria prevented food allergy and suppressed established disease in mice. Every three minutes, a food-related allergic reaction sends someone to the emergency room in the U.S. Currently, the only way to prevent a reaction is for […]

Tamp the Tumor

A growing body of evidence suggests that traditional cancer treatments can paradoxically promote new tumor growth. Now, a team of Harvard Medical School scientists led by Dipak Panigrahy and Allison Gartung of the Cancer Center at Beth Israel Deaconess Medical Center has demonstrated that administration of anti-inflammatory treatments and proresolution […]

Alzheimer’s missing link ID’d, answering what tips brain’s decline

Years before symptoms of Alzheimer’s disease appear, two kinds of damaging proteins silently collect in the brain: amyloid beta and tau. Clumps of amyloid accumulate first, but tau is particularly noxious. Wherever tangles of the tau protein appear, brain tissue dies, triggering the confusion and memory loss that are hallmarks […]

Chemo is a Go for Treating Equine Lymphoma

Cancer isn’t as common for horses as it is for humans and dogs and cats. And because equine cancer symptoms—weight loss, nausea, lethargy, loss of appetite, lameness, skin and coat conditions, among others—often don’t start appearing until the cancer has advanced, it can be hard to reverse its progression. For […]

A new drug target for chemically induced Parkinson’s disease

More than three decades ago, scientists discovered that a chemical found in a synthetic opioid, MPTP, induced the onset of a form of Parkinson’s disease. In a new study led by scientists from the School of Veterinary Medicine, researchers found that an enzyme in the body can metabolize compounds formed […]

Mood Neurons Mature During Adolescence

Researchers have discovered that a mysterious group of neurons in the amygdala – a key center for emotional processing in the brain – remain in an immature, prenatal developmental state throughout childhood. Most of these cells mature rapidly during adolescence, suggesting a key role in the brain’s emotional development, but some stay […]

Study Ties Poor Sleep to Reduced Memory Performance in Older Adults

A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events. The study also found unexpected racial differences in the type of sleep patterns tied to lower memory performance across both younger and […]

Hydrogel Offers Double Punch Against Orthopedic Bone Infections

Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved. Now, researchers have a developed a double-duty hydrogel that both attacks the bacteria and encourages bone regrowth with a single […]

Sugars that coat proteins are a possible drug target for pancreatitis

Pancreatitis is an inflammation of the pancreas that accounts for 275,000 hospitalizations in the United States annually. Patients who suffer from hereditary pancreatitis have a 40 to 50 percent lifetime risk of developing pancreatic cancer. Dannielle Engle, a former Cold Spring Harbor Laboratory (CSHL) Cancer Center postdoctoral fellow who was recently appointed Assistant Professor […]

Low-carb diet may reduce diabetes risk independent of weight loss

A low-carb diet may have benefits for people at risk of developing type 2 diabetes even if they don’t lose any weight, a new study suggests. Researchers at The Ohio State University wanted to know what happens to obese people with metabolic syndrome, a precursor to diabetes, when they eat […]

Cancer is smarter than you think: Q&A with Geeta Mehta

Geeta Mehta studies cancer not simply as masses of cells but as structured organs with multiple cell types that communicate with each other and interact with the body—much like your lungs or liver. “Tumors are not merely cancerous cells that undergo mindless proliferation. Rather, they are highly organized and interconnected organ […]

Screen Time and the Brain

Whether we like it or not, digital devices are everywhere. Some of us can barely put them down, even when we’re with cherished family and friends. While these devices can enhance learning and build community, they can also interfere with everything from sleep to creativity. Pediatrician Michael Rich, wants to […]

Signature of an ineffective immune response to cancer revealed

Our immune system is programmed to destroy cancer cells. Sometimes it has trouble slowing disease progression because it doesn’t act quickly or strongly enough. In a study published in The Journal of Clinical Investigation, researchers from the University of Montreal Hospital Research Centre (CRCHUM) revealed the genetic signature of this […]

Targeting the Microbiome Could Improve Parkinson’s Therapy

For some people with Parkinson’s disease, Levodopa is a wonder drug, capable of eliminating almost overnight the tremors and movement difficulties that characterize the neurodegenerative disorder. Other patients are not so lucky – the drug is either much less effective, or its power seems to wane after just a few […]
