Macrophages infected with germinating Aspergillus fumigatus (Af) conidia undergo lateral transfer during programmed cell death. Representative time-lapse confocal microscopy images show lateral transfer of live Af swollen conidia (shown in green) between monocyte-derived macrophages. Propidium iodide staining (red) shows cell death of a macrophage transferring Af conidia to a neighboring macrophage. The transfer process is highlighted by a black arrow. The images were taken at 10-minute intervals.
