Sticky DNA webs may cause tissue damage linked to severe COVID-19

Sticky webs of DNA released from immune cells known as neutrophils may cause much of the tissue damage associated with severe COVID-19 infections, according to two new studies published on September 14 in the Journal of Experimental Medicine (JEM).

Protein aggregation reduces elasticity of blood vessels during aging

Deposits of a protein called "Medin", which manifest in virtually all older adults, reduce the elasticity of blood vessels during aging and hence may be a risk factor for vascular dementia.

In-depth study of kidney tumors reveals novel markers of response to immunotherapy

Treatments for kidney cancer have improved considerably over the past few decades. In 1988, when Memorial Sloan Kettering oncologist Robert Motzer started researching the disease, the average survival was less than one year.

New technology reveals experimental drugs that help suppress the growth and spread of tumor

A new technology that allows researchers to peer inside malignant tumors shows that two experimental drugs can normalize aberrant blood vessels, oxygenation, and other aspects of the tumor microenvironment in non-small cell lung cancer (NSCLC), helping to suppress the tumor's growth and spread, UT Southwestern researchers report.

Study shows how tumor cells gain enhanced ability to deal with crowded tumor environment

Majority of animal cells must become spherical to undergo cell division. These cells achieve this shape by rounding up and deforming their neighboring cells.

Metastatic cancer cells reshape, destroy or integrate into blood vessels

In laboratory studies, Johns Hopkins Kimmel Cancer Center and Johns Hopkins University researchers observed a key step in how cancer cells may spread from a primary tumor to a distant site within the body, a process known as metastasis.

Researchers identify an effective treatment for severe cases of COVID-19 infection

Scientists are trying to figure out how SARS-CoV-2 leads to a range of symptoms that appear to persist long after the active viral infection.

Macrophage programming allows the body to fight infections and promotes tissue repair

Macrophages are white blood cells that, depending on the signals they get from the immune system, become specialized in either increasing or decreasing inflammation.

Study reveals key biomolecule that can heal damaged heart tissues

When a person suffers a heart attack, parts of the heart can become stiff and scarred, leading to disability and possible progression toward heart failure.

Researchers are developing therapeutic treatments for acute stroke

Every year in the United States, about 800,000 people experience a stroke. Many are left with neurological complications such as paralysis on one side of the body, speech and language problems, vision issues, behavioral changes, and memory loss.

Genes linked to Down syndrome abnormalities may offer protection against solid tumors

Scientists from Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago discovered that a set of genes with decreased expression in individuals with Down syndrome may lead to clinical abnormalities in this population, such as poor muscle development and heart valve problems.

Gut microbes shape our antibodies before we are infected by pathogens

B cells are white blood cells that develop to produce antibodies. These antibodies can bind to harmful foreign particles to stop them invading body cells.

Cholesterol-lowering medication improves function of the coronary arteries

In a pilot study of people living with HIV or high levels of cholesterol, Johns Hopkins Medicine researchers found that a six-week course of a cholesterol-lowering medication improved the function of the coronary arteries that provide oxygen to the heart.

Study shows neo-self antibody as major cause of recurrent pregnancy loss

A research group centered around Kobe University Graduate School of Medicine's Professor YAMADA Hideto and Associate Professor TANIMURA Kenji (Department of Obstetrics and Gynecology), and Professor ARASE Hisashi et al. of Osaka University's Research Institute for Microbial Diseases have revealed for the first time in the world the high frequency of a novel autoantibody in women suffering from recurrent pregnancy loss.
