설명

일반 설명

Pam3CSK4 is a selective toll-like receptor 1/2 (TLR1/2) agonist used in the investigation of TLR1/2 function. It is a synthetic lipopeptide for TLR1/2 and mimics the acylated amino terminus of bacterial lipopeptides. Pam3CSK4, with its three lipid chains, facilitates receptor heterodimerization. The two ester-bound lipid chains are inserted into a pocket in TLR2, while the amide-bound lipid chain is inserted into a hydrophobic channel in TLR1. In the context of human uveitis, endophthalmitis, and experimental uveitis models, Pam3CSK4 triggers the expression and secretion of various cytokines and chemokines in intraocular fluids and/or tissues. A cell-permeable, water-soluble synthetic cationic lipohexapeptide analog of the immunologically active N-terminal portion of bacterial lipoprotein that potently activates monocytes and macrophages. Induces the release of IL-1, IL-6, TNF-α, superoxide, and NO. Promotes the translocation of NF-κB, enhances tyrosine protein phosphorylation and activation of ERK1/2 and MEK1/2.

애플리케이션

Pam₃Cys-Ser-(Lys)₄, Hydrochloride has been used to stimulate MODE-K cells to access its effects on epithelial neuropilin-1 (NRP1) protein expression. It has been used as a toll-like receptor 2 (TLR2) ligand to study TLR2 functionalities.
