A groundbreaking study using a tiny roundworm could pave the way for new treatments for neurodegenerative disorders. Researchers have linked the worm gene swip-10 to copper regulation – a vital element for brain health found in everyday items like wiring and cookware. Understanding the roles of swip-10 and MBLAC1, a protein involved in processing cellular materials, could lead to the development of effective medications and opens new avenues for advancing brain disease treatments.
