Graphical representation of different phagocytic receptors and ligands in microglia and astrocytes. Although microglia are considered the professional phagocytic cell of the brain, astrocytes are also able to modulate neuronal synapsis. In the case of microglia, there are stimuli for both “eat me” and “don’t eat me” signals. Apart from neurons, they are also able to modulate tumor cells (microglia), apoptotic cells (both), and Aβ intake (microglia and in vitro astrocytes). Based on [122,133,134,135].
