From: Inflammation in the avian spleen: timing is everything
Effects of acute melatonin and LPS administration upon cytokine induction in the spleen at midday versus midnight. Plotted values represent the mean ± SEM in each experimental group. Values are represented as the number of transcript copies/1000 GAPDH transcripts following the respective treatments, lipopolysaccharides (LSP), melatonin (Mel), or saline (Sal), ZT6 = midday; ZT18 = midnight. Melatonin was administered one hour prior to challenge with LPS or saline (ZT5). *Statistical significance is based on P < 0.05.
