摘要

Cell motility and adhesion are fundamental components for diverse physiological functions, including embryonic development, immune responses and tissue repair. Dysregulation of these processes can lead to a range of diseases, including cancer. Cell motility and adhesion are complex and often require regulation by an intricate network of signalling pathways, with phosphatidylinositol phosphates (PIPs) having a central role. PIPs are derived from phosphatidylinositol phosphorylation and are instrumental in mediating membrane dynamics, intracellular trafficking, cytoskeletal organization and signal transduction, all of which are crucial for cellular responses to environmental stimuli. Here we discuss the mechanisms through which PIPs modulate cell motility and adhesion by examining their roles at focal adhesions, within the cytoskeleton, at protein scaffolds and in the nucleus. By providing a comprehensive overview of PIP signalling, this Review underscores their significance in maintaining cellular homeostasis and highlights their potential as therapeutic targets in diseases characterized by aberrant cell motility and adhesion.
