A schematic diagram showing the increased pro-inflammatory cytokine production in peritoneal macrophages stimulated with TsV and Ts1.

Abstract

<p>Pro-inflammatory cytokine production occurs via the following two routes: (1) MyD88-dependent signaling, where TsV and Ts1 are recognized by TLR4/CD14/TLR2, resulting in NF-kB nuclear translocation; and (2) MyD88-independent signaling, where TsV is recognized by TLR4/CD14 and activates ERK1/2 and p38 phosphorylation and c-Fos/Jun expression.</p
