Pam3CSK4 induces a dose-dependent response in HEK-Blue™ hTLR2 cells. These cells were stimulated with increasing concentrations of Pam3CSK4. After overnight incubation, the NF-κB response was determined using HEK-Blue™ Detection, a SEAP detection medium, and by reading the optical density (OD) at 630 nm.

  • Scientific Description
    Pam3CSK4 (Pam3CysSerLys4) is a synthetic triacylated lipopeptide (LP) and a TLR2/TLR1 ligand. It is a potent activator of the pro-inflammatory transcription factor NF-κB [1, 2]. Pam3CSK4 mimics the acylated amino terminus of bacterial LPs. Bacterial LPs are a family of pro-inflammatory cell wall components found in both Gram-positive and Gram-negative bacteria. The stimulatory activity of these LPs resides in their acylated amino terminus. These bacterial LPs are recognized by TLR2, a receptor that plays a pivotal role in detecting a diverse range of pathogen-associated molecular patterns (PAMPs) [3]. At the cell surface, TLR2 forms a heterodimer with co-receptors TLR1 or TLR6, depending upon either tri- or diacylation of the ligand. Once a ligand binds to either TLR2-TLR1 or TLR2-TLR6, a MyD88-dependent activation of NF-κB and AP-1 occurs, ultimately leading to an innate immune response. Recognition of Pam3CSK4, a triacylated LP, is mediated by TLR2 which cooperates with TLR1 through their cytoplasmic domain to induce the signaling cascade leading to the activation of NF-κB [4].
