About

Shuichi Nakamura is a leading figure in the biophysics of bacterial motility, with a specialized focus on the unique propulsion systems of spirochetes. His research illuminates how these spiral-shaped pathogens—including the causative agents of syphilis and Lyme disease—achieve their distinctive corkscrew motion. Nakamura’s major contribution lies in elucidating the mechanics of periplasmic flagella (PFs), the internal filaments that enable spirochetes to navigate viscous host environments. His highly cited 2020 work, "Spirochete Flagella and Motility" (65 citations), provides a definitive synthesis of how these endoflagella function within the periplasmic space, distinguishing spirochetes from all other flagellated bacteria. By integrating structural biology with dynamic imaging, Nakamura has revealed how PF rotation generates the cell-body undulations critical for tissue penetration and immune evasion. His findings have profound implications for understanding spirochetal pathogenesis and for designing novel therapeutic strategies that target motility. Through meticulous biophysical analysis, Nakamura continues to decode one of nature’s most elegant and medically relevant forms of microbial movement, establishing himself as an essential voice in bacterial cell biology.
