Mechanism diagram of caffeine inhibiting Mapt acetylation by upregulating SITR2, promoting its nuclear translocation, and improving mitochondrial damage. (A) In normal brain tissue, Mapt is deacetylated and translocated into the nucleus, thereby promoting mitochondrial transcription in the nucleus and maintaining mitochondrial function. (B) After hypoxia-ischemia-induced WMD, the acetylation level of Mapt increased, nuclear translocation decreased, mitochondrial transcription decreased, and damage increased. Induced to caffeine treatment, SIRT2 was activated, Mapt deacetylation increased, nuclear translocation increased, mitochondrial transcription increased, and damage improved.
