Notorious oncogene plays a direct role in disguising growing cancers from the immune system

Cancer-associated genes called oncogenes are well known to stimulate cell growth and division — causing tumors to balloon and spread.

NIH scientists discover an autoinflammatory disease caused by mutations in the LYN gene

Scientists have identified an autoinflammatory disease caused by mutations in the LYN gene, an important regulator of immune responses in health and disease.

How does diet affect inflammation?

In a recent study published in the journal Nutrients, researchers in Italy suggest there is evidence that dietary factors may directly affect the immune system and play a role in chronic systemic inflammation.

UTSW expert advises screening by 55 for people with family history of age-related macular degeneration

Patients with a family history of age-related macular degeneration (AMD), the leading cause of permanent vision loss in those older than 60, should visit an ophthalmologist by age 55 to be screened for signs of the disease, advises an expert at UT Southwestern Medical Center.

New technique lights up cancerous tumors during surgery

A new technique that combines highly detailed, real-time images of inside the body with a type of infrared light has, for the first time, been used during surgery to differentiate between cancerous tumors and healthy tissue.

Severe COVID-19 increases the risk of developing heart disease later in life

Patients who have been hospitalized with severe COVID-19 have permanent changes in their cholesterol 3 months after recovery, according to a study from the University of Oslo. This increases their risk of developing heart disease later in life.

New biomimetic model helps study wound healing in burn and laceration wounds

Burn wounds are notoriously prone to bacterial infection and typically lead to a larger amount of scar tissue than laceration wounds.

Scientists find a good treatment target for pulmonary hypertension

The vascular smooth muscle cells that normally give blood vessel walls strength and flexibility proliferate and become destructive in pulmonary hypertension, a typically rapidly progressing condition that makes it hard to get blood inside our lungs and oxygen to our bodies.

Correcting abnormalities in solid tumor's blood vessels can improve efficacy of CAR-T cell therapy

A type of immune therapy called chimeric antigen receptor (CAR)-T cell therapy has revolutionized the treatment of multiple types of blood cancers but has shown limited efficacy against glioblastoma-;the deadliest type of primary brain cancer-;and other solid tumors.

Cholesterol-lowering drugs show potential to reduce heart disease in sleep apnea patients

A new study by Columbia University researchers suggests that cholesterol-lowering drugs called statins have the potential to reduce heart disease in people with obstructive sleep apnea regardless of the use of CPAP machines during the night.

Ozone pollution associated with increase in hospital admissions for heart attack, heart failure and stroke

The first evidence that exceeding the World Health Organization ozone limit is associated with substantial increases in hospital admissions for heart attack, heart failure and stroke is published today in European Heart Journal, a journal of the European Society of Cardiology.

Study reveals the LDLR pathway as a ubiquitous metabolic vulnerability in high grade gliomas

New research has shown that the blood vessels that feed aggressive brain tumors have receptors that could allow a new type of drug-containing nanoparticle to be used to starve the tumors of the energy they use to grow and spread, and also cause other disruptions to their adapted existence, even killing themselves.

Non-critically ill hospitalized Covid-19 patients could substantially benefit from a higher dose of blood-thinners

Giving noncritically ill patients hospitalized for COVID-19 a higher dose of blood-thinning medication than usual did not significantly reduce the combined risk of death from any cause, need for treatment in an intensive-care unit, a confirmed blood clot or a stroke at 30 days, according to the results of the FREEDOM-COVID trial presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Addition of sotatercept to existing therapy shows promise for the treatment of pulmonary arterial hypertension

Patients with pulmonary arterial hypertension (PAH), a severe, progressive condition that affects the heart and lungs, who were treated with the novel first-in-class medication sotatercept on top of existing therapy experienced significant improvements in walking distance via a six-minute walking test—the study's primary endpoint and a validated surrogate for functional improvement and reduced symptom burden.
