Scientists at UT Southwestern Medical Center and Children’s Medical Center Dallas have discovered in mice how high cholesterol causes blood vessels to become inflamed, a necessary prerequisite for atherosclerosis – the “hardening of the arteries” responsible for most heart attacks and strokes. The findings, published in Nature Communications, could lead to new interventions to protect against cardiovascular diseases (CVD), the leading cause of death globally.

Why do nonsteroidal anti-inflammatory drugs (NSAIDs) exacerbate gastrointestinal infections by Clostridioides difficile, the leading cause of antibiotic-associated diarrhea worldwide? In a new paper published in Science Advances, researchers at Children’s Hospital of Philadelphia (CHOP) have begun to answer that question, showing that NSAIDs disrupt the mitochondria of cells lining the colon, sensitizing them to damage by pathogenic toxins.

People who contract COVID-19 but never develop symptoms – the so-called super dodgers – may have a genetic ace up their sleeve. They’re more than twice as likely as those who become symptomatic to carry a specific gene variation that helps them obliterate the virus, according to a new study led by UC San Francisco researchers.

Led by Dr. Jordi Casanova and Dr. Panagiotis Giannios, a team of researchers at IRB Barcelona and IBMB(CSIC) has revealed the relationship between autophagy and polyploidy, the latter a phenomenon in which cells contain multiple copies of genetic material. In this regard, they have discovered a scenario where the level of autophagy is much higher in cells with several copies of DNA and that it can even trigger this programmed cell death.

The neurons in our bodies are dotted with tiny pores that let essential molecules pass in and out of our cells. Neurons need these channels to send the signals that allow us to move, think, and perceive the world around us. Now, structural biologists at Cold Spring Harbor Laboratory (CSHL) have captured never-before-seen images of one of the largest pores in human neurons.

A multidisciplinary team led by Dr. Ángel R. Nebreda, Dr. María J. Macías and Dr. Modesto Orozco, all at IRB Barcelona, has developed a new type of p38 inhibitor, which preferentially impairs one of the activation pathways of this protein. In particular, these inhibitors block the self-activation (or autophosphorylation) of p38 but allow it to continue to be activated by other mechanisms.
