    Thirst and hunger neurons | ScienceDaily

    To ensure we get the calories and hydration we need, the brain relies on a complex network of cells, signals, and pathways to guide us when to eat, drink, or stop. Yet, much about how the brain deciphers the body’s needs and translates them into action remains unknown. Researchers from the Max Planck Institute for Biological Intelligence, in collaboration with the University of Regensburg and Stanford University, have identified specific populations of neurons in the amygdala — an emotional…

  • Western diet causes inflammation, traditional African food protects

    Western diet causes inflammation, traditional African food protects

    A switch of just two weeks from a traditional African diet to a Western diet causes inflammation, reduces the immune response to pathogens, and activates processes associated with lifestyle diseases. Conversely, an African diet rich in vegetables, fiber, and fermented foods has positive effects. This study, published in Nature Medicine, highlights the significant impact of diet on the immune system and metabolism.

    Lifestyle diseases such as cardiovascular diseases, diabetes, and chronic…

    How researchers are shining a light on kidney disease

    For patients with polycystic kidney disease (PKD), a common genetic disorder that ravages the waste-removing organ with cysts, dialysis and transplantation are among the only treatments.

    More than 12.4 million people worldwide suffer from the dominant form of the condition. Now, Rutgers University geneticists have uncovered fresh details of how the disease progresses — findings that could open the door to new therapies.

    In a study published in Nature Communications, Inna Nikonorova, a…

  • PEPITEM sequence shows effects in psoriasis, comparable to steroid cream

    PEPITEM sequence shows effects in psoriasis, comparable to steroid cream

    Birmingham scientists have shown that a sequence of just three amino acids may reduce the severity of psoriasis, when applied topically in an emollient cream.

    The researchers, whose study is published in Pharmacological Research, identified the smallest part of a peptide (small protein) called PEPITEM, which occurs naturally in the body and regulates inflammation.

    The study also showed that both PEPITEM and the three amino acid (tripeptide) sequence delivered a significant reduction in the…

  • Some gut bacteria could make certain drugs less effective

    Some gut bacteria could make certain drugs less effective

    A new study, published today in Nature Chemistry by researchers from the University of Pittsburgh and Yale University, shows how common gut bacteria can metabolize certain oral medications that target cellular receptors called GPCRs, potentially rendering these important drugs less effective.

    Drugs that act on GPCRs, or G protein-coupled receptors, include more than 400 medications approved by the U.S. Food and Drug Administration (FDA) for treatment of many common conditions such as…

  • Cognitive decline comes sooner for people with heart failure

    Cognitive decline comes sooner for people with heart failure

    There are over six million Americans with heart failure who are at greater risk of losing their cognitive abilities earlier in life, a study suggests.

    The research team, led by Michigan Medicine, examined the cognitive abilities of nearly 30,000 adults over time, comparing those who did and did not develop heart failure.

    The researchers found heart failure is associated with a significant decrease in cognition at the time of diagnosis.

    Global cognition and executive functioning also declined…

  • 17 modifiable risk factors shared by stroke, dementia, and late-life depression

    17 modifiable risk factors shared by stroke, dementia, and late-life depression

    Age-related brain diseases such as stroke, dementia, and late-life depression are a debilitating part of growing older, but people can lower their risk of these diseases through behavioral and lifestyle changes. In a new extensive systematic review, Mass General Brigham researchers identified 17 modifiable risk factors that are shared by stroke, dementia, and late-life depression. Modifying any one of them can reduce your risk of all three conditions. The findings, which provide evidence to…

  • New Ultrasound Technology Stimulates Immune Cell Therapy

    New Ultrasound Technology Stimulates Immune Cell Therapy

    Immune cells are generated to keep our bodies healthy. To combat disease, our bodies initiate two separate waves of immunity. The first wave, known as innate immunity, is a generalizable response that tries to inhibit pathogens and stop disease progression. The second wave, known as adaptive immunity, is more specific and includes T and B cells. Both cell types generate a response that directly targets the invading pathogen. T cells are a specialized…

    New Target Improves Immunotherapy Treatment in AML Patients

    Immunotherapy has revolutionized the way physicians treat patients with cancer. This form of cancer treatment aims to direct the immune system toward the rapidly growing tumor. As cancer progresses, tumor cells secrete different proteins and molecules to suppress the body’s immune system. Various mechanisms are responsible for doing this, including surface proteins on cancer that inactivate specific immune cells, known as T cells. Many cells are…

    Pharma Dodges The Tariff Bullet

    President Donald Trump acted with restraint in his New Liberation Day tariffs, when he deferred imposing tariffs on pharmaceutical products from China, India and Europe. But, so long as these tariffs are being considered, their potential threat to the pharmaceutical industry and the people it serves remains.

    These are difficult times for drug discovery and manufacturing. John Crowley the CEO of the Biotechnology…
