Microglial subtypes. 1: Resting microglia with ramified morphology with a lot of processes and branches. miR-124 is involved in the resting state of microglia. 2: Activated microglia with ameboid morphology. 2a: M1, activated microglia associated with an inflammatory state. 2b: M2, microglia in an anti-inflammatory state. 3a: Cytokines that can produce an inflammatory environment, such as Il-6 or TNF-alpha. 3b: Cytokines with anti-inflammatory properties (Il-4, Il-10, for example).
