Among those signaling pathways, activation of NF-kappaB leads to up-regulation of IL-1beta, IL-8 and TNF-alpha, mucin MUC2 and Toll-like receptor 2 (TLR2), whereas activation of p38 MAP kinase mediates not only up-regulation of inflammatory mediators and mucin MUC5AC but also down-regulation of TLR2.

Finally, glucocorticoids synergistically enhance NTHi-induced TLR2 expression via specific up-regulation of the MAP kinase phosphatase-1 that, in turn, leads to inactivation of p38 MAP kinase, the negative regulator for TLR2 expression.
