General description
肽聚糖。是一种生物聚合物，是革兰氏阳性菌细胞壁的主要成分。肽聚糖由 N -乙酰基葡糖胺和 N -乙酰基胞壁酸交替单位的碳水化合物骨架组成，并被 D -和 L -氨基酸修饰。 N -乙酰胞壁酸残基与寡肽交联。末端肽为 D -丙氨酸，但其他氨基酸以 D -异构体存在。
Application
肽聚糖可用于裂解酶（如裂解酶）的活性评估。建议使用浓度为 0.15-3μ 的肽聚糖g/ml，溶于水或缓冲液，在 450 nm 处测定。肽聚糖不溶解，但在水中产生混悬液。
肽聚糖可激活 Toll 样受体 2 (TLR2)，TLR2 存在于哺乳动物细胞中以刺激淋巴细胞。也可作为 Poly (I:C) 的拮抗剂发挥作用。

Gene family encoding allograft inflammatory factor-1 (AIF-1) is well conserved among organisms; however, there is limited knowledge in lower organisms. In this study, the first AIF-1 homologue from cnidarians was identified and characterised in the sea anemone Anemonia viridis. The

Antimicrobial peptide (AMP) is a crucial component of the innate immune system in crustaceans. In mud crab, Scylla paramamosain, a commercially important species, a glycine-rich antimicrobial peptide (Spgly-AMP) gene was newly identified and putatively encoded a 26aa signal peptide and

Intestinal inflammation induces alterations of the gut microbiota and promotes overgrowth of the enteric pathogen Salmonella enterica by largely unknown mechanisms. Here, we identified a host factor involved in this process. Specifically, the C-type lectin RegIIIβ is strongly upregulated during
