This meeting will focus directly on mechanisms of eukaryotic chemotaxis. Because chemotaxis is critical for development (especially in neurobiology), immunology, wound healing, and tumor cell metastasis, the meeting is designed to bring together the leading chemotaxis researchers in these fields for cross-fertilization of concepts and approaches. This strategy is manifested by organizing each topic according to stage in the signal processing pathway; for example, researchers in different fields who are focused chemotaxis receptors are grouped together in a single session. The session topics are chosen to focus attention on the critical steps in chemotactic signaling, providing attendees with an integrated overview of the entire chemotaxis process over the course of the entire meeting.
