Through a quirk of anatomy, women are especially prone to urinary tract infections, with almost half dealing with one at some point in their lives.  Scientists have been trying to figure out for decades how bacteria gain a foothold in otherwise healthy people, examining everything from how the microbes move inside and stick to the inside of the bladder to how they deploy their toxins to produce uncomfortable and often painful symptoms. Research published in PNAS examines how the bacteria Escherichia coli, or E. coli—responsible for most UTIs—is able to use host nutrients to reproduce at an extraordinarily rapid pace during ...

Households with gas or propane stoves regularly breathe unhealthy levels of nitrogen dioxide, a study of air pollution in U.S. homes found. “I didn’t expect to see pollutant concentrations breach health benchmarks in bedrooms within an hour of gas stove use, and stay there for hours after the stove is turned off,” said Stanford Doerr School of Sustainability Professor Rob Jackson, senior author of the May 3 study in Science Advances. Pollution from gas and propane stoves isn’t just an issue for cooks or people in the kitchen, ...

Most people have heard the famous phrase “the enemy of my enemy is my friend.” Now, Northwestern University researchers have used statistical physics to confirm the theory that underlies this famous axiom. The study will be published on May 3 in the journal Science Advances. In the 1940s, Austrian psychologist Fritz Heider introduced social balance theory, which explains how humans innately strive to find harmony in their social circles. According to the theory, four rules — an enemy of an enemy is a friend, a friend of a ...

The outbreak of a deadly disease called stony coral tissue loss disease is destroying susceptible species of coral in the Caribbean while helping other, “weedier” organisms thrive — at least for now — according to a new study published today in Science Advances. Researchers say the drastic change in the region’s population of corals is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies. “Some fast-growing organisms, like algae, ...

Activated T cells that carry a certain marker protein on their surface are controlled by natural killer (NK) cells, another cell type of the immune system. In this way, the body presumably curbs destructive immune reactions. Researchers from the German Cancer Research Center (DKFZ) and the University Medical Center Mannheim (UMM) now discovered that NK cells can impair the effect of cancer therapies with immune checkpoint inhibitors (ICI) in this way. They could also be responsible for the rapid decline of therapeutic CAR-T cells. Interventions in this mechanism could ...

PHILADELPHIA — (May 3, 2024) — The Wistar Institute assistant professor Filippo Veglia, Ph.D., and team, have discovered a key mechanism of how glioblastoma — a serious and often fatal brain cancer — suppresses the immune system so that the tumor can grow unimpeded by the body’s defenses. The lab’s discovery was published in the paper, “Glucose-driven histone lactylation promotes the immunosuppressive activity of monocyte-derived macrophages in glioblastoma,” in the journal Immunity. “Our study shows that the cellular mechanisms of cancer’s self-preservation, when sufficiently understood, can be used against the disease very effectively,” ...

A research group at the Department of Biochemistry and Molecular Biology of the University of Seville has made a significant advance by discovering the crucial role of the protein Galectin-3 in the progression of various types of brain tumours. In these tumours, the most abundant immune system cells, microglia and macrophages, overexpress Galectin-3, which creates an immunosuppressed environment which inhibits the action of other immune cells against cancer cells. In vitro findings have shown that specific inhibition of Galectin-3 in microglial cells promotes expression of proinflammatory markers and reverses the presence of key immunosuppressive ...

Evidence from archaeological sites in the medieval English city of Winchester shows that English red squirrels once served as an important host for Mycobacterium leprae strains that caused leprosy in people, researchers report May 3 in the journal Current Biology. “With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy,” says senior author Verena Schuenemann of the University of Basel in Switzerland. “The medieval red squirrel strain we recovered is more closely related to medieval human strains from the same city than to strains isolated from infected ...

The first panoramic view of infection pathways in the human placenta has been created, which could highlight potential drug targets to develop pregnancy-safe therapies for malaria, toxoplasmosis and listeria, all diseases that can cause severe pregnancy complications.     Researchers from the Wellcome Sanger Institute, the University of Cambridge, the University of Dundee, and collaborators, used novel ‘mini placenta’ models to map the placental response to infections in early development. This ...

Researchers at the University of Basel and the University of Zurich have been able to prove that British squirrels carried leprosy bacteria as early as the Middle Ages. Further results revealed a link between the pathogens found in the medieval rodents and those in the local human population during that period. Skin spots, deformed noses, ulcers: leprosy, is an infectious disease that can bring about some serious symptoms. The bacterium responsible, Mycobacterium leprae, which still infects around 200,000 people each year especially in the Global South, also has a long history in Europe. The international research group led by paleogeneticist Professor Verena Schünemann ...
