OHSU Scientists Discover Internal 'Trade Winds' That Drive Protein Movement in Cells
• Oregon Health & Science University researchers revealed a previously unknown system of directed fluid flows within cells that rapidly transport essential proteins to the cell's leading edge, published today in Nature Communications. • The breakthrough emerged from an accidental observation during a neurobiology course when scientists used lasers to track protein movement and discovered an unexpected wave of soluble actin being pushed forward rather than drifting randomly through the cell. • The discovery fundamentally reshapes understanding of cell migration, cancer metastasis, and wound healing by revealing that cells use active internal mechanisms rather than passive diffusion to position critical proteins.
