Microscopic photograph of monocyte derived macrophage (MDM), undergoing autophagy characterised by presence of autophagy puntae of LC3 protein (green colour dots) inside cell. Image was taken with a fluorescence-inverted microscope DMI6000 B (Leica) in FU Berlin. Autophagy is an important cellular process considered to have important role in cell survival (during starvation) as well as in cell death (in different diseases). Nucleus of MDM is in blue colour.
