    Nanomechanical Mechanisms of Lyme Disease Spirochete Motility Enhancement in Extracellular Matrix

    Designing a system that mimics natural environmental signals, which many spirochetes face during their infectious cycle, the authors observed that a subset of their surface proteins, particularly Decorin binding protein A/B, could strongly enhance the motility of spirochetes in the ECM of the host.
