Effects of Coff/Caff plus Mel on cytokine levels in N2a/APP cells treated with regimen 1.

Notes: N2a/APP cells were treated with Coff (A–D) or Caff (E–H) at 10 μM for 12 hours in the day, followed by Mel at 1, 5, or 10 μM for another 12 hours in the night. The cytokine levels were determined by ELISA.

Abbreviations: Aβ, amyloid-β; ANOVA, analysis of variance; APP, amyloid precursor protein; Caff, caffeine; Coff, coffee; ELISA, enzyme-linked immunosorbent assay; IFN, interferon; IL, interleukin; Mel, melatonin; N2a, Neuro-2a.
