Senolytic Treatments Clear Harmful Senescent Microglia from the Aging Brain

From the abstract

Researchers here show that a few different senolytic approaches improve the state of the population of microglia in the white matter of the brain in aged mice. This is much as one might expect, given past work into the effects of clearing senescent cells on cognitive function and neurodegeneration in various mouse models. Microglia are innate immune cells of the brain. The presence of senescent and inflammatory microglia is important in the age-related disruption of normal function in the brain,
