Triptans, a commonly prescribed class of migraine drugs, may also be useful in treating obesity, a new study by scientists at UT Southwestern suggests. In studies on obese mice, a daily dose of a triptan led animals to eat less food and lose weight over the course of a month, the team reported in the Journal of Experimental Medicine.
Although the different SARS-CoV-2 variants currently in circulation are undoubtedly less severe in vaccinated individuals in the general population, immunocompromised people are at greater risk of developing severe forms of COVID-19.
Two broadly neutralizing antibodies show great promise to provide long-acting immunity against COVID-19 in immunocompromised populations according to a paper published June 15 in the Journal of Experimental Medicine (JEM). The antibodies were effective against all SARS-CoV-2 variants of concern tested and could be used alone or in an antibody cocktail to diminish the risk of infection.
A research group led by Kazunobu Sawamoto, a professor at Nagoya City University and National Institute for Physiological Sciences, and Chihiro Kurematsu, a student at Nagoya City University School of Medicine, has elucidated the mechanism that controls synaptic pruning of new neurons in the adult brain. These findings are expected to be useful in the study of neurological diseases with abnormalities in microglia and synapses, such as autism spectrum disorders (ASDs).
Researchers at the University of California, San Francisco (UCSF), have discovered that cells carrying the most common mutation found in human cancer accumulate large amounts of ferrous iron and that this “ferroaddiction” can be exploited to specifically deliver powerful anticancer drugs without harming normal, healthy cells. The therapeutic strategy, described in a study to be published March 9 in the Journal of Experimental Medicine (JEM), could be used to treat a wide variety of cancers driven by mutations in the KRAS gene.
Studying mice, researchers at Washington University School of Medicine in St. Louis have discovered that roseolovirus can trigger autoimmunity in a previously unknown way: by disrupting the process by which immune cells learn to avoid targeting their own body's cells and tissues.
PIK3CA-related overgrowth spectrum (PROS) is a group of rare, incurable disorders caused by mutations in the PIK3CA gene that result in the malformation and overgrowth of various parts of the body.

Researchers at the University of California, San Francisco, have discovered that aggressive, triple-negative breast cancers (TNBCs) can evade treatment by reorganizing and softening the collagen matrix that surrounds the cancer cells. The study, which will be published April 2 in the Journal of Experimental Medicine (JEM), shows that the softer matrix activates a signaling pathway that promotes the cancer cells’ survival, and suggests that targeting this pathway could enhance the effectiveness of chemo- and radiotherapy in TNBC patients.
Researchers at the University of Alabama at Birmingham have identified a new molecular target that could potentially treat the deadly, aging-related lung disease idiopathic pulmonary fibrosis (IPF). The study, which will be published March 10 in the Journal of Experimental Medicine (JEM), suggests that targeting a protein called MDM4 could prevent respiratory failure by initiating a genetic program that removes scar tissue from the lungs.
