No differences were seen between pre and 24 hr.-post infection time points for expression of the important molecules involved in Toll-like receptor (TLR) activated pathways of IL-10 production such as myeloid differentiation primary-response protein 88 (MYD88), extracellular signal regulated kinase (ERK), nuclear factor-κB (NF-κB) or p38 mitogen-activated protein kinases. This evidence concerns the gene NFKB1 and infection.
