Extracellular lactate enhances IL-10 transcription via H4K5 lactylation and promotes an A2-like reactive-astrocyte phenotype after ischemic stroke.
BACKGROUND Ischemic stroke triggers a rapid rise in lactate levels in the brain tissue. The neuroprotective role of exogenous lactate administered during the reperfusion phase has recently garnered attention. A neuroprotective A2 phenotype of reactive astrocytes (RACs) is characterized by interleukin-10 (IL-10) upregul...
