Regulatory Mechanism for Sperm Chemotaxis and Flagellar Motility

Explore a detailed seminar presentation on the regulatory mechanisms governing sperm chemotaxis and flagellar motility, delivered by Dr. Kogiku Shiba from the University of Tsukuba. Delve into the fascinating world of eukaryotic flagella and cilia, examining their crucial role in cell motility and signal reception through the study of Ciona sperm. Learn about the complex molecular and cellular biology behind flagellar motility regulation, including how sperm navigate using chemical attractants, the mechanics of flagellar wave propagation, and the role of calcium signaling in directional swimming. Discover cutting-edge research on calcium-binding proteins like calaxin, ion channel functions in chemoattractant sensing, and novel approaches to understanding single-cell swimming behavior through Ethological dynamics. The presentation incorporates experimental findings, analytical systems, and recent research developments in understanding these fundamental biological processes that are conserved throughout evolution.
