Inflammatory mast cells up-regulate angiogenesis during squamous epithelial carcinogenesis
In the context of AD, fisetin has been shown to modulate inflammatory pathways and maintain cognitive function in AD transgenic mice (53) and to enhance memory and induce hippocampal long-term potentiation in rats (54)
PET scans have revealed altered cerebral blood flow, with increases in regions, such as the anterior cingulate cortex, and decreases in the cerebellum (Liu et al., 2021)
