内吞体

PE结构域Ⅱ的作用是使裂解后的毒素部分或其他效应分子从内吞体转位到细胞质。

The function of domain II is to translocate the cleaved part of the toxin or other effectors from endosome to cytosol .

结论内吞体功能复杂，它可能与细胞的pH值，水盐代谢，能量、蛋白质的代谢以及活性氧的产生等都有一定的关系。

Conclusion Endosome has complicated function and probably relates with cellular pH , the metabolism of water and salt , the metabolism of energy , protein and the production of active oxygen .

结果：溶酶体内的酶活性可被NaF所抑制，溶酶体和内吞体股上的酶活性则不能被NaF抑制，但能被NEM所抑制。

As a result , it is found that the enzyme activity Inside the matrix of lysosome can be inhibited by NaF , but insensitive to the enzyme activity on the lysosome and endosome membrane , the enzyme activity can be inhibited by NEM .

几种酶在大鼠内吞体膜上的细胞化学定位

The Localization of Several Enzyme Activities on the Membrane of Endosome

目的研究多种酶在不同器官内吞体膜上的活性。

Objective : To investigate cytochemical localization of enzymes on the membrane of endosome in different organs .

术后8周，生物性人工腱膜被降解吸收部位，有较多的粗面内质网发达的成纤维细胞和直径相近的胶原原纤维，巨噬细胞减少，内吞体减少。

At the 8 weeks after the transplantation , The bioartificial aponeurosis were absorbed , where there were abundant rough endoplasmic reticulum , fibroblasts , and collagen fibrils of different sizes .
