New breakthrough unveils how Guanylate Binding Proteins (GBP) defend against bacterial infections, paving the way for innovative therapies

Scientists at Delft University of Technology have discovered that our immune system uses Guanylate Binding Proteins (GBPs) to fight off bacterial infections by forming a destructive coat around bacteria. This research, published in Nature Structural & Molecular Biology, could open up new avenues for innovative treatments. GBP1: A crucial defense mechanism Guanylate Binding Protein 1 (GBP1) plays a critical role in our body’s innate immune response by targeting bacterial and parasitic pathogens. Researchers have now identified how GBP1 surrounds bacteria with a protein coat, tightening around them to break the bacterial membrane, allowing immune cells to clear the infection. Groundbreaking research This breakthrough was achieved using cryogenic electron microscopy, enabling scientists to visualize the detailed process of how GBP1 forms its defensive coat. Further biophysical experiments allowed the researchers to decode the antibacterial mechanism, offering new insights that could lead to the development of targeted therapies for infections, particularly in individuals with weakened immune...
