目的探讨妊娠期母鼠及其子代接触尘螨点刺液（Derp）对发育后期个体Th1/Th2平衡及哮喘发生的影响。方法Wistar大鼠根据母体妊娠期及新生早期是否接触Derp随机分为对照组、母Derp-仔Derp-组（母鼠和其子代均未接触Derp）、母Derp＋仔Derp＋组（母鼠和其子代均接触Derp）和母Derp＋仔Derp-组（母鼠接触Derp,其子代未接触Derp）,分别皮下注射Derp或生理盐水,30d龄时除对照组外,其余3组以卵白蛋白（OVA）为变应原致敏并雾化吸入,诱发哮喘发生。取血浆检测OVA特异性IgE抗体、收集外周血单个核细胞（PBMC）用ELISA法检测培养上清中细胞因子IL-4和IFN-γ水平,行支气管肺泡灌洗记录支气管肺泡灌洗液（BALF）中嗜酸性粒细胞的计数,留取肺组织行病理学检查。结果母Derp＋仔Derp＋组在哮喘建模后PBMC培养上清中IFN-γ水平显著低于母Derp-仔Derp-组,IL-4水平显著升高,IL-4/IFN-γ比值升高,OVA特异性IgE、BALF中嗜酸性粒细胞计数显著高于母Derp-仔Derp-组;母Derp＋仔Derp-组与母Derp-仔Derp-组IL-4和IFN-γ水平差异均无统计学意义,OVA特异性IgE水平虽有增高,但差异不具统计学意义,BALF中嗜酸性粒细胞计数差异无统计学意义。母Derp＋仔Derp＋组Th2优势显著高于母Derp＋仔Derp-组。结论胎鼠对于Derp跨胎盘的致敏作用可通过母体妊娠期间的免疫来完成,这一过程会根本上导致Th2优势免疫的发生,增加了变态反应性疾病的危险性。     

Th1/Th2漂移与HCV感染慢性化

Thl和Th2细胞分别介导机体的细胞免疫和体液免疫,它们来自一个共同的前体细胞Th0,在不同的细胞因子、抗原等因素的影响下,可发生Thl与Th2的转换。HCV感染时,Th1应答与丙型肝炎的好转有关,Th2应答与丙型肝炎慢性化有关。因此,Thl与Th2之间的漂移对HCV感染的转归有重要影响,是HCV感染慢性化的重要机制。     

Intravenous immunoglobulin treatment in women with recurrent abortions: increased cytokine levels and reduced Th1/Th2 lymphocyte ratio in peripheral blood

PROBLEM: The aim of this study was to investigate changes in peripheral blood Th1/Th2 cytokine levels and lymphocyte ratios after massive intravenous immunoglobulin (MIVIg) treatment for women with recurrent spontaneous abortion (RSA) of unexplained etiology. METHOD OF STUDY: Serum Th1 (IFN-gamma, TNF-alpha) and Th2 cytokine (IL-4, IL-10) levels were assessed by ELISA methods (n = 9) and peripheral blood Th1/Th2 lymphocyte ratios (n = 4) by flow cytometry before and after MIVIg treatments in women with four or more consecutive RSA. RESULTS: Pre-treatment serum IFN-gamma (0.06 +/- 0.09 pg/mL, mean +/- SD), TNF-alpha (0.21 +/- 0.45 pg/mL), IL-4 (0.70 +/- 1.16 pg/mL), and IL-10 (1.12 +/- 1.67 pg/mL) increased to 0.17 +/- 0.16 pg/mL, 0.77 +/- 0.28 pg/mL, 1.82 +/- 0.89 pg/mL, and 3.44 +/- 0.48 pg/mL, respectively, after MIVIg treatments (P < 0.05). CD4-positive IFN-gamma/IL-4 lymphocyte ratios (17.3 +/- 9.1) were reduced to 11.5 +/- 7.1 after treatment (P < 0.05). CONCLUSIONS: Massive intravenous immunoglobulin treatments increased peripheral blood cytokine levels and decreased Th1/Th2 lymphocyte ratios; thus, MIVIg treatments modify the peripheral Th1/Th2 balance.     

Human airway and peripheral blood eosinophils enhance Th1 and Th2 cytokine secretion

BACKGROUND: The effector function of eosinophils involves their release of toxic granule proteins, reactive oxygen species, cytokines, and lipid mediators. Murine studies have demonstrated that eosinophils can also enhance T cell function. Whether human eosinophils, in particular, airway eosinophils, have similar immunoregulatory activity has not been fully investigated. The aim of this study was to determine whether human blood and airway eosinophils can contribute to Th1 and Th2 cytokine generation from CD4+ T cells stimulated with superantigen. METHODS: Eosinophils were obtained from blood or bronchoalveolar lavage fluid 48 h after segmental allergen bronchoprovocation. Purified eosinophils were co-cultured with autologous CD4+ blood T cells in the presence of staphylococcal enterotoxin B (SEB). Cytokine levels in the supernatant fluid were determined by enzyme-linked immunosorbent assay (ELISA). Eosinophil expression of major histocompatibility complex (MHC) class II and co-stimulatory molecules was assessed by flow cytometry before culture, 24 h after granulocyte-macrophage colony-stimulating factor (GM-CSF) stimulation, and 24 h after co-culture with CD4+ T cells and SEB. RESULTS: Interleukin (IL)-5, IL-13, and interferon (IFN)-gamma generation increased when CD4+ T cells were co-cultured with either blood or airway eosinophils in the presence of SEB. The ability of eosinophils to enhance cytokine generation was independent of their source (blood vs airway), activation by GM-CSF, or detectable expression of human leukocyte antigen (HLA)-DR, CD80, or CD86. CONCLUSION: Our data demonstrate that SEB-induced generation of Th1 and Th2 cytokines is increased in the presence of human blood and airway eosinophils. Thus, eosinophils can have an immunoregulatory function in pathogen-associated allergic diseases such as atopic dermatitis, chronic sinusitis, and asthma exacerbations.     

Th1/Th2 cytokine responses following HIV-1 immunization in seronegative volunteers

The Th1/Th2 profile that follows human vaccination may profoundly influence the subsequent course of disease after infection. However, the ability to detect IL-4 has been limited outside trials of live vaccination. By using methods in which memory effector cells are allowed to antigenically expand by short term culture, followed by low-dose mitogenic stimulation, we have been able to follow the Th1/Th2 profile in HIV-1^?volunteers enrolled in two phase I studies of HIV immunogens (a recombinant gp120 and a multivalent, octomeric V3 loop peptide). Antigen-specific interferon-gamma (IFN-γ) could be detected in primary stimulation, but IL-4 was observed only after antigenic expansion and restimulation. In both of these studies the responses after initial immunizations were dominated by IFN-γ, with IL-4 appearing only after multiple rounds of immunization, and IL-4 was temporally related to antibody production. Concomitant with the IL-4 production, the amount of supernatant IFN-γ declined. Antigen-specific IL-10 was not detected in either study. Such techniques, which have been shown to correlate with outcomes in immunotherapy, may prove useful as future surrogates of human vaccine response.     

Expression of lncRNA NEAT1 in peripheral blood mononuclear cells of patients with systemic lupus erythematosus and its correlation with Th1/Th2 balance

Objective: This study explored and analyzed the expression of LncRNA NEAT1 in peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SLE) and its correlation with Th1/Th2 balance. Methods: We chose 97 SLE patients admitted in our hospital from Jun. 2016 to Feb. 2019 as SLE group, and randomly selected 50 healthy volunteers that underwent physical examination in our hospital during the same period as control group. We detected the expression of LncRNA NEAT1 in PBMCs of the two groups of subjects by qRT-PCR, the degree of Th1 and Th2 cells in both groups by flow cytometry, and the expression of TFN-γ and IL-4 in both groups by ELISA. Results: The relative expression of LncRNA NEAT1 in PBMCs of SLE group was higher than that of control group (P<0.05). The proportion of Th1 and the ratio of Th1/Th2 cells in PBMCs were markedly lower in the SLE group than the control group (P<0.05), while the proportion of Th2 was higher in the SLE group than the control group (P<0.05). IFN-γ level in SLE group was much lower than the control group (P<0.05), while IL-4 level was evidently higher in the SLE group than in controls (P<0.05). The expression of LncRNA NEAT1 in PBMCs of SLE group was notably negatively correlated with Th1 proportion and Th1/Th2 ratio (P<0.05), while positively correlated with Th2 proportion (P<0.05). Conclusion: LncRNA NEAT1 in PBMCs of SLE patients is abnormally highly expressed, and this expression is negatively correlated with Th1/Th2 balance. These two factors may interact and jointly affect the occurrence and progression of SLE.     

Effect of glutamine on Th1 and Th2 cytokine responses of human peripheral blood mononuclear cells

Decreased glutamine concentrations are found in patients with catabolic stress and are related to susceptibility to infections. In this study, we evaluated the role of glutamine in Th1/Th2 cytokine responses. Peripheral blood mononuclear cells were stimulated with phytohemagglutinin (PHA), live attenuated bacillus Calmette-Guérin (BCG), or measles virus in the presence of different glutamine concentrations. We found that glutamine at an optimal concentration (0.6 mM) significantly enhanced PHA-stimulated lymphocyte proliferation as well as Th1 [interferon-gamma (IFN-gamma) and interleukin-2 (IL-2)] and Th2 cytokine (IL-4 and IL-10) production. In the absence of glutamine, BCG and measles virus elicited minimal lymphocyte proliferation, whereas BCG enhanced Th1 cytokine response and measles virus promoted Th2 cytokine response. Interestingly, addition of glutamine promoted the BCG-elicited Th1 cytokine response (IFN-gamma), but suppressed the measles-induced Th2 cytokine response (IL-10). These results suggest that appropriate glutamine levels may influence host responses to different antigens and microorganisms. Furthermore, predominately Th1, but not Th2, cytokine responses required the presence of optimal concentrations of glutamine.     

膜表达的HLA-G1对同种反应性PBMC分泌Th1/Th2型细胞因子的影响

目的研究人脐静脉内皮细胞系(ECV304)表达的HLA-G1对同种异体外周血单个核细胞(PBMC)Th1/Th2型细胞因子分泌的影响。方法采用脂质体介导的基因转染技术将pcDNA3-HLA-G1转入ECV304,以间接免疫荧光技术在蛋白质水平上检测HLA-G1分子在ECV304上的表达;以表达HLA-G1的ECV304作为刺激细胞,灭活后,与健康人PBMC共同培养,用ELISA检测上清液中Th1/Th2型细胞因子的浓度,观察HLA-G1对同种异体抗原激活的PBMC分泌Th1/Th2型细胞因子的影响。结果与转染pcDNA3空质粒的对照组相比,HLA-G1能使PBMC的IL-10分泌增加(P<0.05),而IL-2,IFN-γI、L-4分泌无明显影响。结论HLA-G1能引起由同种异体抗原激活的PBMC分泌IL-10增加,提示HLA-G1有可能使Th1/Th2型细胞因子向Th2型偏移。     

Th1/Th2迁移与紫癜性肾炎的研究进展

辅助性T细胞亚群平衡是维持机体正常的免疫状态的重要因素，其失衡参与许多疾病，特别是免疫相关性疾病的发生、发展。过敏性紫癜是儿童时期常见病和多发病，是儿童继发性肾炎的最常见的原因，与患儿自身免疫状态紊乱密切相关。

目的探讨自身免疫性溶血性贫血（AIHA）患者外周血Th1／Th2、Th3／Tr1细胞状态,分析它们在AIHA发病机制中的作用。方法收集AIHA患者及健康者外周抗凝静脉血,分离纯化淋巴细胞。运用FITC-CD3单抗,Cy5-CD4单抗,PE—CRTH2单抗,以CD3／CD4设门作三色流式细胞术检测Th1／Th2细胞,ELISA法检测血清中Th3细胞相关的细胞因子TGF-β1的含量和Tr1细胞的相关因子IL-10的含量。结果与正常对照相比．AIHA患者外周血CD3^＋CD4^＋CRTH2-T细胞（Th1）百分率、CD3^＋CD4^＋CRTH2^＋T细胞（Th2）百分率均下降（P〈0．05）,而CD4^＋CRTH2^-T／CD4^＋CRTH2^＋T比例（Th1／Th2）均明显升高（P〈0．01）,Th3／Tr1细胞分泌的相关细胞因子TGF-β1和IL-10的含量均降低（P〈0．05）。结论AIHA患者外周血存在细胞免疫功能失调,T细胞亚群极化状态发生改变,呈Th1型细胞优势,Th3／Tr1细胞因子含量下降,可能与AIHA的免疫学发病机制有关。     

Analysis of apoptosis and a Th1/Th2 phenotype in HIV-infected patients

Lymphocytes from HIV patients, unlike those from normal HIV-negative subjects, underwent apoptosis upon in vitro culture. We found that the percentage of lymphocytes undergoing apoptosis was significantly higher (P = 0.005) in patients with low CD4 cell counts (< 200 CD4 cells/μl) (60%) than in patients at earlier stage (> 500 CD4 cells/μl) (35%). Serum IgE levels increased in two of six patients at last stage and in two of five patients at earlier stage. Spontaneous production of both IL-2 and IL-10, by peripheral blood mononuclear cells (PBMC) after 48 h in culture, was greater in HIV-infected subjects and increased with disease progression. IFN-γ production was greater in HIV-infected subjects but there was no evident change with disease progression. IL-4 production was barely detectable or not detected in both HIV-infected and HIV-negative individuals. These results indicate that spontaneous apoptosis is associated with advanced disease. However, there was no evidence of in vivo switch from the Th1 to Th2 phenotype in HIV-infected patients.
