PKC-ε Vesicles Fuse into the Phagosome. BMDM expressing PKC-ε-GFP undergoing frustrated phagocytosis. Images were collected every 8 seconds for 10 min by TIRFM. Fire LUT was applied for better visualization of fluorescence intensity. Bright puncta representing vesicles are seen entering the phagosome and diffuse into the membrane over time.
