A heat map showing the number of differentially expressed genes (DEG) and the direction of log fold change (LFC) of expression values in the spleen of the Fayoumi and broiler chicken breeds at 22 days of age after 7 hours of heat treatment at 35°C, and/or 3.5 hours post lipopolysaccharide (LPS) treatment.

<p>DEG have an FDR ≤ 0.05 and LFC ≥ ± 2.</p>
