  • How Zika virus knocks out our immune defenses

    How Zika virus knocks out our immune defenses

    Zika virus and dengue virus are very close relatives. Both are mosquito-borne flaviviruses, and both specialize in infecting a host’s dendritic cells.

    But a new Nature Communications study, led by scientists at La Jolla Institute for Immunology (LJI) and UC San Diego shows that these two viruses have vastly different ways of making us sick.

    Zika virus uses stealth. Zika virus slips into dendritic cells and blocks the dendritic cells from alerting nearby T cells to danger. It’s the classic…

  • Could an arthritis drug unlock lasting relief from epilepsy and seizures? Promising results in mice

    Could an arthritis drug unlock lasting relief from epilepsy and seizures? Promising results in mice

    A drug typically prescribed for arthritis halts brain-damaging seizures in mice that have a condition like epilepsy, according to researchers at the University of Wisconsin-Madison.

    The drug, called tofacitinib, also restores short-term and working memory lost to epilepsy in the mice and reduces inflammation in the brain caused by the disease. If the drug proves viable for human patients, it would be the first to provide lasting relief from seizures even after they stopped taking it.

    “It…

  • Study unravels mystery of cancer-fueling enzyme–could lead to new therapies

    Study unravels mystery of cancer-fueling enzyme–could lead to new therapies

    For organs to develop, grow and regenerate, cells must proliferate. But when that process goes awry, leading to uncontrolled cell growth, cancer can emerge.

    New CU Boulder research, published in the journal Science Advances, offers unprecedented insight into how an enigmatic enzyme, known as CDK7, drives this complex process. The research shows that novel cancer drugs designed to inhibit CDK7 can, within minutes, shut down gene expression pathways that drive cell proliferation in dozens of…

    Postpartum female preference for cooler temperatures linked to brain changes

    Mothersexperience major metabolic adaptations during pregnancy and lactation to support the development and growth of the new life. Although many metabolic changes have been studied, body temperature regulation and environmental temperature preference during and after pregnancy remain poorly understood. Researchers at Baylor College of Medicine and collaborating institutions show in the journal Molecular Metabolism that postpartum female mice develop new environmental temperature preferences…

  • Lupus-related antibody shows promise in enhancing cancer treatment efficacy

    Lupus-related antibody shows promise in enhancing cancer treatment efficacy

    Yale scientists have discovered a promising way to trigger immune responses against certain tumors, using a lupus-related antibody that can slip, undetected, into “cold” tumors and flip on an immune response that has been turned off by cancer. The research, published in Science Signaling on March 25, offers new findings that could help improve therapies for glioblastoma and other aggressive cancers that are difficult to treat.

    “It turns out when this antibody gets into the cell’s cytoplasm…

  • New Evidence Links Microplastics with Chronic Disease

    New Evidence Links Microplastics with Chronic Disease

    Tiny fragments of plastic have become ubiquitous in our environment and our bodies. Higher exposure to these microplastics, which can be inadvertently consumed or inhaled, is associated with a heightened prevalence of chronic noncommunicable diseases, according to new research being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).

    Researchers said the new findings add to a small but growing body of evidence that microplastic pollution represents an…

  • Growing body of evidence links HPV with heart disease

    Growing body of evidence links HPV with heart disease

    In addition to causing several types of cancer, human papillomavirus (HPV) appears to bring a significantly increased risk of heart disease and coronary artery disease, according to a study being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).

    Evidence that HPV is linked with heart disease has begun to emerge only recently. This new study is the first to assess the association by pooling data from several global studies, totaling nearly 250,000 patients….

  • ‘Low-sugar’ vaccine can provide broad immunity against coronavirus variants

    ‘Low-sugar’ vaccine can provide broad immunity against coronavirus variants

    Sugar coatings aren’t only for candies; they also help viruses, like the ones that cause COVID-19, hide from their hosts’ immune system. Now, researchers have developed a universal vaccine that targets coronaviruses and the sugars that they use as cover. As demonstrated in animal studies, the vaccine removed sugar molecules from an area of a coronavirus spike protein that rarely mutates and created effective and plentiful antibodies to inactivate the virus.

    Chewing gum can shed microplastics into saliva, pilot study finds

    Plastic is everywhere. And many products we use in everyday life, such as cutting boards, clothes and cleaning sponges, can expose people to tiny, micrometer-wide plastic particles called microplastics. Now, chewing gum could be added to the list. In a pilot study, researchers found that chewing gum can release hundreds to thousands of microplastics per piece into saliva and potentially be ingested.

    The researchers will present their results at the spring meeting of the American Chemical…
