| Research Abstract |
A series of cells lacking phosphoinositide-metabolizing enzymes was prepared from Raw264.7 macrophages. The cells were transfected with fluorescent probes, which bind to specific phosphoinositides. The life spans of various phosphoinositides on phagosome during phagocytosis in these cells were monitored by time-pulse imaging. Thus the enzymes responsible for the life spans of the phosphoinsitides were determined. The results will contribute to clarify the mechanism involved in autophagy and intracellular trafficking.
