Hypothesis
Can apigenin and luteolin modulate microglial activation through inhibition of CD40 expression?
Conclusion
Apigenin and luteolin may prevent microglial-mediated inflammation by modulating CD40 expression in response to IFN-γ.
Supporting Evidence
- Apigenin and luteolin concentration-dependently suppressed IFN-γ-induced CD40 expression.
- Both compounds significantly reduced TNF-α and IL-6 production in microglia.
- Apigenin and luteolin inhibited IFN-γ-induced phosphorylation of STAT1.
Takeaway
Apigenin and luteolin are plant compounds that can help calm down brain cells that get too excited and cause inflammation, which is bad for brain health.
Methodology
Cultured microglia were treated with apigenin and luteolin, and CD40 expression was analyzed using FACS, along with cytokine levels measured by ELISA.
Limitations
The study does not address the low bioavailability of flavonoids in humans.
