一般說明

Pam3CSK4 是一种选择性 Toll 样受体 1/2 (TLR1/2) 激动剂,用于研究 TLR1/2 功能。它是 TLR1/2 的合成脂肽,模仿细菌脂肽的酰化氨基末端。 Pam3CSK4 具有三条脂质链,可促进受体异二聚化。两条酯结合脂质链插入 TLR2 中的口袋中,而酰胺结合脂质链插入 TLR1 中的疏水通道中。在人类葡萄膜炎、眼内炎和实验性葡萄膜炎模型背景下,Pam3CSK4 可触发眼内液和/或组织中的各种细胞因子和趋化因子表达和分泌。[1] 一种能有效激活单核细胞和巨噬细胞的细菌脂蛋白免疫活性N端部分的可渗透细胞的水溶性合成阳离子脂六肽类似物。诱导IL-1、IL-6、TNF-α、超氧化物和NO的释放。促进NF-κB的易位,增强酪氨酸蛋白磷酸化和ERK1/2和MEK1/2的活化。

應用

PamCys-Ser-(Lys)盐酸盐可用于刺激 MODE-K 细胞,了解其对上皮神经纤毛蛋白-1 (NRP1) 蛋白表达的影响。[2]它可用作 Toll 样受体 2 (TLR2) 配体,研究 TLR2 功能。[3]
