This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

The results by invert embedding TEM showed that higher invasive CCL229cells had vast of ER,which distributed throughout cytosol especially largeamount of vesicle-like and flatten cisternal rER in pseudopodia or cell processesand membranous flow-like structure from perinuclear region to pseudopodia,and less Golgi complex.

倒置包埋法常规透射电镜对人大肠癌细胞的超微结构观察结果显示，高侵袭力的CCL229细胞中内质网数量较多并呈全细胞分布，尤其在细胞伸出的众多伪足中含有丰富的小泡状和扁平囊样粗面ER结构，而且观察到由小泡形成的&膜流样&结构从核周一直深入到伪足中，但细胞中高尔基器少见。

Reg4 protein is constitutively expressed in parietal cells of the gastric mucosa and the neuronendocrine cells of intestinal epithelium.

Reg4蛋白主要表达于胃黏膜壁细胞和小肠上皮神经内分泌细胞，与胃肠道细胞的增殖分化有关。
