白癜风患者血清白细胞介素33及其可溶性受体ST2水平检测及意义

 目的:探讨白癜风患者血清白细胞介素33（IL-33）及其可溶性受体ST2（sST2）表达水平的变化及其临床意义。方法：采用酶联免疫吸附试验对62例白癜风患者和30例健康对照组血清IL-33和sST2表达水平进行检测,并分析IL-33和sST2在白癜风患者不同分期、面积、病程等分组中的表达差异。结果：白癜风患者外周血中IL-33和sST2水平在进展期及稳定期均明显高于正常对照组（IL-33：t值分别为4.67、2.34,P值分别为0.004、0.031;sST2：t值分别为3.59、2.09,P值分别为0.027、0.045）。白癜风患者自身抗体异常组sST2水平明显高于无自身抗体异常组,差异有统计学意义（t=2.46,P=0.015）;不同分期、性别、白斑面积、家族史、精神应激、微量元素临床亚组间IL-33和 sST2水平差异均无统计学意义（P值均>0.05）。外周血IL-33和 sST2水平与年龄及病程均无明显相关性（P值均>0.05）。结论：IL-33及sST2可能与白癜风的发病密切相关。IL-33水平升高可能主要发生在白癜风起始阶段,与疾病活动度及严重程度无明显相关。sST2水平的升高可能是IL-33介导的炎症反应和免疫应答的负反馈调节机制。

Serum levels of soluble IL-2 receptor, soluble ICAM-1, TNF-alpha, interleukin-4 and interleukin-6 in scleroderma

Background A variety of immunological markers have been reported to be elevated in patients with systemic scleroderma (SSc). Objective The aim of this study was to determine which of the following parameters: soluble IL-2 receptor (sIL-2r). soluble ICAM-1 (sICAM-1), tumour necrosis factor (TNF-alpha), interleukin-6 (IL-6) and interleukin-4 (IL-4) reflect the clinical stage of the disease and how they correlate with each other. Methods In 31 scleroderma patients the serum levels of these markers were measured in the same blood sample using ELISA test kits. The results were correlated with clinical findings such as extent of skin disease, inflammatory disease activity and involvement of internal organs. Results SIL-2r, slCAM-1 and TNF-alpha showed significant differences in subgroups of SSc patients in contrast to IL-4and IL-6, The five parameters did not correlate with each other. Conclusion sIL-2r, sICAM-1 and TNF-alpha showed differences in subgroups of scleroderma and therefore they may be useful in further studies as markers of disease activity.

Increased IgE-levels in bullous pemphigoid correlate to soluble low affinity Fc-II-receptor for IgE and soluble IL-2-receptor

Background Increased serum-IgE levels in patients with bullous pemphigoid (BP) are one of the well known immunological deviations in this autoimmune dermatosis. Aim and methods Since the mechanism that leads to an increase of IgE in BP is still unclear, we investigated serum-IgE levels and IgE regulating cytokines (soluble low affinity Fc II receptor for IgE, IL-4, IFN-g and soluble IL-2 receptor) in sera and blister fluids of 15 BP patients before and during treatment with immunosuppressants using an ELISA-technique. Results All 15 patients examined proved to have high IgE levels in blister fluids (> 100 KU/l) and 13 of the 15 patients had elevated serum-IgE levels. Soluble low affinity Fc II receptor for IgE (sCD23R) was also increased in sera (7.9 ± 2.4 pg/ml) and ten fold higher in blister fluids (76.7 ± 15.3 pg/ml). Investigation of cytokines interfering with IgE production showed significantly increased levels of the soluble IL-2 receptor in sera whereas the concentrations of IL-4 and IFN-g revealed no significant differences compared to controls. In blister fluids we detected all the cytokines investigated. During treatment with immunosuppressants the elevated concentrations of sCD23R and soluble IL-2 receptor were reduced to normal values. Conclusions The results show a direct correlation between IgE levels, sCD23R and soluble IL-2-receptor concentrations and suggest a connection between increased IgE levels and T-cell activation in BP.     

生殖器疱疹外周血T淋巴细胞亚群及sIL—2R水平的检测

生殖器疱疹(GH)是由单纯疱疹病毒(HSV)感染引起的一种常见的易复发性传播疾病。为进一步探讨     

干细胞因子及其受体与白癜风

在皮肤表皮层，干细胞因子表达于角质形成细胞，其受体表达于黑素细胞，二者不但参与神经嵴细胞发育为黑素细胞进程中黑素细胞分化、增殖和迁移过程，而且在维持成熟黑素细胞正常功能中也发挥作用。阻断干细胞因子与其配体的结合可导致黑素细胞合成黑素功能受损，白癜风患者皮损中发现二者存在表达异常；因此，干细胞因子及其配体可能参与白癜风的发病过程。

白癜风光疗疗效与临床的关系

白癜风是一种色素脱失性疾病,以皮肤或黏膜色素减退为特征,多为后天发病,可见于任何年龄,以青壮年多见,部分患者有明显的季节性,一般春末夏初病情加重,冬季缓解.任何部位均可发病,但好发于暴露部位.该病治疗困难,影响美观,给患者带来精神心理压力.目前运用较广泛的有308 nm准分子激光、窄谱中波紫外线和氦氖激光等,临床应用发现,光疗的疗效与白癜风分型、部位、病程、治疗次数、皮肤类型和红斑反应等相关.     

Defective IL-2 receptor expression in lymphocytes of patients with arsenic-induced Bowen’s disease

Abstract The immune function of peripheral mononuclear cells (MNC) in patients with endemic arsenic-induced Bowen’s disease (BD) was investigated. Many cytokines and immune-related factors were determined in the present study. Interleukin-1β and TNF-α production was used as an indicator of monocyte/macrophage function. Il-2 and sIL-2R production was used as an indicator of lymphocyte activation. The release of sCD4 and sCD8 was used as an indicator of activation of respective T-cell subpopulations. Production of IFN-γ and IL-2 reflected the cellular effector function of helper T-cells type 1. In vivo cell-mediated immunity was also assessed by estimation of the percentage of T-cells in peripheral blood MNC and the nonspecific delayed-type hypersensitivity (DTH) response to 2,4-dinitrochlorobenzene (DNCB). Both assays revealed depressed cell-mediated immunity in BD. Compared with healthy controls, spontaneous and PHA-induced IFN-γ and TNF-α production was significantly decreased in BD whereas spontaneous release of IL-2, sCD4 and sCD8 was significantly increased. Although PHA stimulation increased IL-2 release, the expression of IL-2R α and β chains and the release of sIL-2R were not proportionately increased in BD. In addition, IL-2-mediated [³H]-thymidine incorporation by MNC in patients with BD was significantly decreased. These findings suggest that the defective cell-mediated immune function in BD is due to impairment of membrane IL-2R expression in lymphocytes after stimulation.
