General description

A cell-permeable synthetic peptide containing mouse TIRAP138-151 fused to the Drosophila Antennapedia sequence. Specifically inhibits LPS-, but not CpG-induced NF-κB activation, PKR phosphorylation, and JNK phosphorylation in RAW.κB cells at ~40 µM. Also reported to block IκBα degradation.
A synthetic, cell-permeable peptide that corresponds to mouse toll-interleukin 1 receptor (TIR) domain-containing adapter protein 138-151 (TIRAP; also called Mal (MyD88-adapter-like), fused to the Drosophila antennapedia sequence. Shown to specifically inhibit LPS-induced, but not CpG-induced, NF-κB activation, PKR phosphorylation, and JNK phosphorylation in RAW.κB cells at ~40 µM. Also reported to block IκBα degradation.

Pathways and Biomarkers of Toll-like Receptor (TLR) Signaling

"Toll-like Receptors (TLRs) are transmembrane proteins that are expressed on various immune cells. The extracellular N-terminal region of TLRs recognizes specific pathogen components. At least 13 different members of TLR family have been identified that detect different pathogen associated molecular patterns (PAMPs), including lipopolysaccharides, flagellin, bacterial CpG DNA, and viral RNA and DNA. Recognition of PAMPs by TLRs is considered as a key process for the induction of an inflammatory response."
