According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years. During a heart attack, or myocardial infarction (MI), a blocked artery and the resulting oxygen deprivation cause massive cardiac cell death, blood vessel impairment and inflammation. Now, researchers reporting in ACS Biomaterials Science & Engineering have developed a cardiac patch with tiny engineered blood vessels that improved recovery from MI in rats and pigs.

To effectively treat MI, lost heart muscle tissue must regenerate and new blood vessels must form to restore oxygen and nutrients to cells...

With insights into a molecular pathway that regulates the activity of Tregs, a type of T cell involved in immunosuppression, new research opens up possibly new avenues for treating inflammatory and autoimmune diseases.

Immune response is a balancing act: Too much can lead to inflammatory or autoimmune disease; too little could lead to a serious infection...

People with cancer who exercise generally have a better prognosis than inactive patients. Now, researchers at Karolinska Institutet in Sweden have found a likely explanation of why exercise helps slow down cancer growth in mice: Physical activity changes the metabolism of the immune system’s cytotoxic T cells and thereby improves their ability to attack cancer cells. The study is published in the journal eLife.

“The biology behind the positive effects of exercise can provide new insights into how the body maintains health as well as help us design and improve treatments against cancer,” says Randall Johnson, professor at the Department of Cell and Molecular Biology, Karolinska Institutet, and the study’s corresponding author.

Prior research has shown that physical activity can p...

Hospitalized COVID-19 patients who were taking a daily low-dose aspirin to protect against cardiovascular disease had a significantly lower risk of complications and death compared to those who were not taking aspirin, according to a new study led by researchers at the University of Maryland School of Medicine (UMSOM)...
