For example, mRNA transcripts were detected for genes encoding macrophage pattern recognition receptors (PRRs) such as TLR2 and TLR4, which are involved in the recognition of evolutionarily conserved pathogen-associated molecular patterns (PAMPs), and inflammatory cytokines including IL1B, IL6, and IL10 following infection; however, these were not DE between treatments (adjusted P-value of 0.01). Here, TLR4 is linked to infection.
