Microglia are innate immune cells resident in the brain. They are broadly similar in behavior to the macrophages found elsewhere in the body, with an added portfolio of duties relating to maintenance of the synaptic connections that link neurons to form neural networks. Researchers have provided evidence for microglia to both harm and help the aging brain, with various subpopulations of microglia either acting to cause damage and dysfunction or attempting to resist that damage and dysfunction.
