Certain HLA genes may increase ovarian cancer risk in women

Researchers in the Center for Immunotherapy at Roswell Park Cancer Institute have evaluated the human leukocyte antigen (HLA), a group of genes that help regulate the body's immune system, for underlying differences in ovarian cancer patients' response to therapy.

Study shows birth defects in immune system function may contribute to malnutrition

Malnourished children are most likely to die from common infections, not starvation alone, and immune disorder may be part of the cause, according to a review led by Queen Mary University of London.

ART trial: Adacolumn shows clinical benefit in refractory ulcerative colitis patients

Data from the 48-week ART trial, presented today at the Digestive Disease Week meeting, showed that remission and response rates were 37.2% and 53.2% respectively at week 12, in patients with moderate-to-severe, steroid-dependent active ulcerative colitis (UC) with insufficient response or intolerance to immunosuppressants and / or biologics when treated with between five and eight sessions with Adacolumn.

Bone marrow transplantation dose may have lasting effects on HSC behavior

Unlike aspirin, bone marrow doesn't come with a neatly printed label with dosage instructions. However, a new study published in Cell Reports provides clues about how the dose of transplanted bone marrow might affect patients undergoing this risky procedure, frequently used to treat cancer and blood diseases.

New approach offers unprecedented view of how HIV virus infects and appropriates host cell

Viruses attack cells and commandeer their machinery in a complex and carefully orchestrated invasion. Scientists have longed probed this process for insights into biology and disease, but essential details still remain out of reach.

Personalized DXM-loaded leukosomes may help treat inflammation

Nanosized Trojan horses created from a patient's own immune cells have successfully treated inflammation by overcoming the body's complex defense mechanisms, perhaps leading to broader applications for treating diseases characterized by inflammation, such as cancer and cardiovascular diseases.

Investigational drug abemaciclib shows durable clinical activity for variety of cancer types

The investigational anticancer therapeutic abemaciclib, which targets CDK4 and CDK6, showed durable clinical activity when given as continuous single-agent therapy to patients with a variety of cancer types, including breast cancer, non-small cell lung cancer (NSCLC), glioblastoma, and melanoma, according to results from a phase I clinical trial.

Cornell researchers develop nanoparticle-based drug delivery mechanism for combination cancer therapy

A team of researchers from Cornell University in Ithaca, New York demonstrated a drug delivery mechanism that utilizes two independent vehicles, allowing for delivery of chemically and physically dis-tinct agents.

New ultrasound method provides way to measure acoustic-mechanic properties of cells

In brief, the new method involves exposing cells to ultrasound when they flow through a so-called micro-channel inside a chip.

Diets rich in fruits and vegetables can help prevent chronic inflammation

A new study by the University of Liverpool's Institute of Ageing and Chronic Disease has identified food stuffs that can help prevent chronic inflammation that contributes to many leading causes of death.

Soluble factors from white blood cells may improve tissue healing after skin grafting

Extensive burn injuries are usually treated by transplanting layers of skin from other parts of the body. Although this is a commonly used method, the wounds do not always heal completely.

Researchers agree to test new stem cell gene therapy for Sanfilippo disease in human trial

Scientists in Manchester, who have developed a stem cell gene therapy to reverse a fatal childhood illness, have agreed to work with a new therapeutics company to test it in a human trial.

University of Glasgow-led study could lead to improved treatments for lymphoma, other cancers

A study by scientists at the University of Glasgow, which reveals the critical role a common cancer-associated gene plays in lymphoma development, could lead to improved treatments for a range of cancers.

Potential new intraocular treatment based on RAS manipulation can prevent or reverse diabetic retinopathy

Pathologic changes of the retina caused by diabetes is the leading cause of blindness in working adults. Diabetic retinopathy has no known cure, treatment options are inadequate, and prevention strategies offer limited protection. In the first of its kind, a report in The American Journal of Pathology describes a potential new intraocular treatment based on manipulating the renin angiotensin system (RAS) that both prevents and reverses some characteristics of diabetic retinopathy in a mouse model.

Research shows spleen MZ B cells produce signaling proteins involved in inflammatory responses

The inability to adequately respond to infection can cause a whole-body state of inflammation known as sepsis. This can eventually lead to systemic inflammatory response syndrome (SIRS), and even death.

Researchers investigate effects of new steroid treatment on children with ARDS

Acute Respiratory Distress Syndrome (ARDS) affects hundreds of thousands of people each year, many of them children. Those with this life threatening condition have severely injured and wet lungs, and are treated with mechanical ventilation.

Duke scientists develop human-derived antibody that preferentially attacks cancer cells

A research team from Duke Health has developed an antibody from the body's own immune system that preferentially attacks cancer cells.

Experimental drug ozanimod moderately effective in treatment of ulcerative colitis

Researchers at University of California San Diego School of Medicine have shown that ozanimod (RPC1063), a novel drug molecule, is moderately effective in the treatment of ulcerative colitis. Results of the Phase II clinical trial will appear in the May 5 issue of the New England Journal of Medicine.

Researchers find gene variants that predict adverse effects of hyperthyroidism drugs

Researchers and doctors at Uppsala University, along with Swedish and international collaboration partners, have found gene variants that predict the risk of a serious adverse reaction to drugs used for the treatment of hyperthyroidism. The results are published in The Lancet Diabetes & Endocrinology.
