Our previous studies have identified an undescribed regulatory DC subset, which were developed from differentiation of mDCs educated by splenic stromal cells.diffDCs secret high levels of IL-10 and NO, and inhibit proliferation of activated CD4+ T cells, suggesting its negative feedback control on the immune response in the late phage.

diffDCs是本室最近发现的新型调节性DC亚群，由mDCs在脾脏基质细胞的作用下分化而来，具有高分泌IL-10和NO、抑制抗原特异性CD4~+T细胞增殖的功能，提示浙江大学博士学位论文中文摘要可能在获得性免疫应答晚期起负性调控作用。

They can colonize in human stomach nearly all the time because human immun system can not eradicate them. Vacuolating cytotoxin A is the unique secreted toxin of Hp that induces vacuolation of epithelial cell and is closely related to the incidence of disease in a population infected with Hp.

空泡毒素基因的表达产物—VacA是Hp所特有的分泌性毒素，是Hp的重要毒力因子，在体外，它能使哺乳动物上皮细胞发生空泡样变化，最终导致细胞死亡，它与Hp感染者的发病与否相关。

Sample collection: Two hundred and fifteen sera samples of normal population were collected from the peripheral blood of healthy blood donors of Shenyang, and the sera were separated by centrifugation after blood clotting; The patients sera were collected from the outpatients and inpatients of No. 1 hospital of China Medical University and the Second hospital of Jilin University. Syphilis was confirmed by clinical and serum test of TPHA and RPR; That of pemphigus vulgarism was confirmed not only by clinical, histopathological examination, but also by direct and indirect immunofluorescence test. DIF test on lesion or non-lesion skin showed immunoglobin and/or C3 deposits in the intercellular space of epidermis, and IIF test showed positive anti- intercellular antibody in patient serum using mouse's or rat's tongue or esophagus as substrate.

标本的收集：正常人的血清：采集沈阳市正常献血员外周静脉血共215份，待血凝后离心分离血清；患者的血清：来自中国医科大学一院及吉林大学二院门诊及住院部的病人，梅毒患者除了病史及临床表现外，全部经血清学TPHA及RPR确认；寻常性天疱疮患者除了临床及组织病理诊断外，还进行了直间接免疫荧光的检测，直接免诊断疫荧光：在皮损区及非皮损区的表皮细胞间显示IgG和/或C3补体沉积；间接免疫荧光用鼠或兔的舌或食管作为底物，在病人的血清中显示有肯定的细胞间抗体。
