Hypoxia reverses the early anti-inflammatory microglial response to the β-amyloid peptide: mitochondrial involvement and beneficial roles of melatonin and naringenin
Exploration of hypoxia's role in microglial response reveals that mitochondrial function and SIRT1 are key factors, indicating potential protective roles of melatonin and naringenin.
Key Points
Mild hypoxic conditions induce a shift in microglial activation, heightening inflammatory responses in early Alzheimer's disease.
Exposure to hypoxia significantly increased caspase 1 and NF-kB activity while affecting mitochondrial morphology and function.
Natural substances like melatonin and naringenin show potential to induce SIRT1, partially mitigating hypoxia's adverse effects.
Findings suggest that early hypoxic insults represent a risk factor for Alzheimer's progression and may guide therapeutic approaches.
