一般說明

化学结构:肽

應用

Bactenecin的活性已被作为环状分子以其线性形式而得以研究。它已被用于研究Trk1p在其他抗真菌肽机制中的功能作用。它已被用于研究趋化因子和细胞因子的产生、宿主细胞中基因表达的改变以及宿主细胞对细菌成分的促炎反应的抑制。

生化/生理作用

Bactenecin是一种来自牛中性粒细胞的含12个氨基酸的阳离子抗菌肽。它可与LPS牢固结合并扰乱其内膜的结构、流动性和渗透性。这会导致细胞溶质的泄漏和随后的细菌死亡。

Intracellular pathogens selected for increased susceptibility to polycations are commonly attenuated, yet the effect of decreased susceptibility to polycations on pathogenicity has not been researched. The polymyxin-resistant mutant Brucella abortus AJ100 was characterized by comparing its susceptibility to the polycationic

Recent studies have demonstrated that in addition to their antimicrobial activity, cationic host defense peptides, like the human cathelicidin LL-37, perform many activities relating to innate immunity, including the induction or modulation of chemokine and cytokine production, alteration of gene
