A helper T(Th)1-mediated response is known to enhance cell -mediated immunity, while a Th2-mediated response is associated with the humoral immunity that if elevated IgE levels and eosinophilia. Prostaglandin (PG)E$_2$results in the decreased capability of Iymphocytes to produce Thl cytokines, with a shift toward a Th2 cytokine response. Chlorpyrifos (CPF) has been reported to impair the blastogenesis and response of T Iymphocytes. CPF also induces delayed febrile effects, which results from the activation of COX -PGE$_2$pathway. The purpose of this study is to determine the effort of CPF on the in vitro production of Th cytokines and the role of PGE$_2$on the CPF-induced production of Th cytokines. Splenocytes obtained from male BALB/c mice were pretreated with CPF(0.1, 1, 10 and 100$\mu$M) in the presence of absence of indomethacin or PGE$_2$for 12 h and then were incubated with concanavalin (Con) A for 48 h. These results showed that CPF remarkedly reduced the production of splenic interleukin (IL)-2 and interferon (IFN)-γ in a dose-dependent manner. CPF significantly increased the splenic IL-4 production at low doses (0.1 and 1$\mu$M) but did not affect at high doses (10 and 100 $\mu$M). Indomethacin reduced the CPF-decreased production of IL-2 and IFN-γ in a dose -dependent manner and significantly attenuated the production of IL-4 increased by CPF 0.1 $\mu$M. High dose of CPF significantly reduced the PGE$_2$-decreased production of IL-2 and IFN-γ, while the PGE$_2$- induced production of IL-4 was significantly enhanced by CPF 1 $\mu$M. These findings suggest that CPF nay down-regulate the immune response of Th 1 type by the suppressed production of IL-2 and IFN-γ, with a shift toward a Th2 cytokine response. The CPF-decreased production of Thl cytokines may not be mediated by endogenous PGE$_2$. Also, CPF may attenuate the exogenous PGE$_2$-decreased Th 1 immune response in a dose--dependent manner but may affect dose-independently the PGE$_2$-induced Th2 immune response.

Thymic stromal lymphopoietin (TSLP) is an interleukin-7-like cytokine that is an important trigger and initiator of many allergic diseases. TSLP promotes a T-helper type 2 (Th2) cytokine response that can be pathological. A relationship is formed both at the induction phase of the Th2 response through polarization of dendritic cells to drive Th2 cell differentiation and at the effector phase of the response, by promoting the expansion of activated T cells and their secretion of Th2 cytokines and TSLP. In transgenic mice with TSLP overexpression, it has been reported that TSLP leads to the development of mixed cryoglobulinemic membranoproliferative glomerulonephritis. In addition, TSLP can play an important role in the pathogenesis of IgA nephropathy and systemic lupus erythematosus-related nephritis. From our knowledge of the role of TSLP in the kidney, further studies including the discovery of new therapies need to be considered based on the relationship between TSLP and glomerulonephritis.

Objectives : Ulmus davidiana (UD) has been widely used in Korean herbal medicines used for treatment of acute and chronic inflammatory diseases, such as rhinitis, asthma, and abscess. In this study, To investigated the protective effect of UD on type 1 allergic response, we determined whether UD inhibits early and late allergic response. Methods : The effect of UD was analyzed by ELISA and RT-PCR in RBL-2H3 cells. Levels of ${\beta}$ -hexosaminidase, interleukin (IL)-4 and TNF-${\alpha}$ were measured using enzyme-linked immunosorbent assays (ELISAs). mRNA levels of COX-2 and T-helper type 2(Th2) cytokines were analyzed with RT-PCR. Results : We found that UD suppressed ${\beta}$-hexosaminidase release in RBL-2H3 not only by the PMA plus A23187 stimulation, but also by the IgE-DNP-HSA stimulation at the antigen-antibody binding stage and antibody-receptor binding stage. UD also significantly inhibited COX2 level, along with reduced Th2 cytokine levels, such as IL-3, IL-4, IL-5, IL-13, GM-CSF, and TNF-${\alpha}$ in RBL-2H3. Conclusions : Our results indicate that UD protects against type 1 allergic response and exerts an anti-inflammatory effect through the inhibition of degranulation and expression of COX2 and Th2 cytokines.

This study aimed to investigate the antibody responses in mice immunized with Gnathostoma spinigerum crude antigen (GsAg) incorporated with the combined adjuvant, a synthetic oligonucleotide containing unmethylated CpG motif (CpG ODN 1826) and a stable water in oil emulsion (Montanide ISA720). Mice immunized with GsAg and combined adjuvant produced all antibody classes and subclasses to GsAg except IgA. IgG2a/2b/3 but not IgG1 subclasses were enhanced by immunization with CpG ODN 1826 when compared with the control groups immunized with non-CpG ODN and Montanide ISA or only with Montanide ISA, suggesting a biased induction of a Th1-type response by CpG ODN. After challenge infection with live G. spinigerum larvae, the levels of IgG2a/2b/3 antibody subclasses decreased immediately and continuously, while the IgG1 subclass remained at high levels. This also corresponded to a continuous decrease of the IgG2a/IgG1 ratio after infection. Only IgM and IgG1 antibodies, but not IgG2a/2b/3, were significantly produced in adjuvant control groups after infection. These findings suggest that G. spinigerum infection potently induces a Th2-type biased response.

In this present study, we determined the immunoregulatory activity of ginsenoside Rd extract from Panax ginseng. To determine the activity, we tested Rd against $CD4^+$ Th cells in a murine model of type 1 diabetes, which involves Th1-dominant immunity. The type 1 diabetes was caused by streptozotocin (STZ) and the severity of the diabetes was evaluated by measuring the degree of hyperglycemia, a major symptom of diabetes. The data resulting from experiments showed that ginsenoside Rd induced a greater level of Th1 type cytokines [IFN-${\gamma}$ & IL-2] than Th2 type [IL-4 & IL-10] (P<0.05), which was determined by cytokine profile analysis. In the animal model of diabetes, the depletion of $CD4^+$ Th cells by a treatment of anti-CD4 mAb resulted in considerably lower values of blood-glucose levels than those of the mAb-untreated mice, which indicates that the Th1 immune response from $CD4^+$ Th cells are responsible for diabetes. Based on these observations, the effect of Rd on diabetes was examined in the same animal model. Results showed that Rd-treated mice groups had increased levels of blood glucose compared to Rd-untreated mice groups that were used as a negative control (P<0.05). In other words, Rd aggravated the diabetes via the Th1 immune response. In conclusion, ginsenoside Rd had an immunoregulatory activity of Th1-dominant immunity.

The $M_r$ 63,000 glycoprotein (GP63) and lipophosphoglycan (LPG) of Leishmania donovani were evaluated as vaccine candidates against visceral leishmaniasis. Mice were immunized with liposomeencapsulated GP63 and/or LPG that were purified from the soluble extract of L. donovani promastigotes, and were challenged with virulent amastigotes. Mice immunized with GP63/LPG in liposomes plus BCG resulted in a 27.4% reduction of amastigotes in the liver compared to the control group (liposomes plus BCG), and mice immunized with liposome-GP63 plus BCG failed to induce a protective immune response against the challenge infection. Immunization of mice with GP63 fused to the Schistosoma japonicum glutathione S-transferase (GP63-GST) plus BCG also failed to elicit protective immunity. To analyze the cause of failure to induce protection, cytokine release from the spleen cells of immunized mice and Leishmania-specific serum antibodies were analyzed. Spleen cells from mice immunized with GP63-GST plus BCG that were exposed to soluble extract of L. donovani in vitro produced 10-fold greater quantities of IFN-gamma and 3-fold greater quantities of IL-5 than cells from mice receiving BCG only or saline. Western blot analysis revealed that sera from these mice had Leishmania-specific antibodies recognizing 1 to 3 antigens of L. donovani with M. W. of 60-65 kDa. Although immunization of mice with GP63-GST induced a strong Th1 response, this study indicated that GP63-GST simultaneously elicited the Th2 response of the CD4+ T-cell, which was known to abrogate the protective immune response conferred by the Th1 effector function.

Peripheral blood mononuclear cells (PBMCs) discriminate microbial pathogens and induce T-cell responses of appropriate effector phenotype accordingly. Toll-like receptors (TLRs), in part, mediate this microbial recognition and differentiation while the development of T-cell effector functions critically depends on the release of Th1- or Th2- type cytokines. In the present study, buffalo PBMCs were stimulated under in vitro culture conditions by Bacillus subtilis cell wall petidoglycan, a TLR2 ligand, in a dose- and time- dependent manner. The expression of TLR2 as well as the subsequent differential induction of the Th1 and Th2 type cytokines was measured. Stimulation was analyzed across five doses of peptidoglycan ($10{\mu}g/ml$, $20{\mu}g/ml$, $30{\mu}g/ml$, $40{\mu}g/ml$ and $50{\mu}g/ml$) for 3 h, 12 h, 24 h and 36 h incubation periods. We observed the induction of TLR2 expression in a dose- and time-dependent manner and the peptidoglycan induced tolerance beyond $30{\mu}g/ml$ dose at all incubation periods. The correlation between peptidoglycan stimulation and TLR2 induction was found positive at all doses and for all incubation periods. Increased production of all the cytokines was observed at low doses for 3 h incubation, but the expression of IL-4 was relatively higher than IL-12 at the higher antigen doses, indicating tailoring towards Th2 response. At 12 h incubation, there was a pronounced decrease in IL-4 and IL-10 expression relative to IL-12 in a dose- dependent manner, indicating skewing to Th1 polarization. The expression of IL-12 was highest for all doses across all the incubation intervals at 24 h incubation, indicating Th1 polarization. The relative expression of TNF-${\alpha}$ and IFN-${\gamma}$ was also higher while that of IL-4 and IL-10 showed a decrease. For 36 h incubation, at low doses, relative increase in the expression of IL-4 and IL-10 was observed which decreased at higher doses, as did the expression of all other cytokines. The exhaustion of cytokine production at 36 h indicated that PBMCs became refractory to further stimulation. It can be concluded from this study that the cytokine response to sPGN initially was of Th2 type which skews, more pronouncedly, to Th1 type with time till the cells become refractory to further stimulation.

LP-BM5 murine leukemia retrovirus induces the excessive oxidative stress and immune dysfunction leading to B cell leukemia and murine AIDS with cytokine dysfunction. In the present study, the immune restoratory effect of antioxidant hormone dedydroepiandrosterone sulfate (DHEAS) was investigated in the primary splenocytes from LP-BM5 retrovirus-infected C57BL/6 mice. DHEAS significantly increased T and B cell response to mitogen and normalized the unbalanced production of Th1/Th2 type cytokines. In particular, both protein and mRNA expression of IL-4, IL-6, and $TNF-\alpha$ were down-regulated by DHEAS treatment whereas IL-2 and $IFN-\gamma$ level were increased. This result suggests that DHEAS directly or indirectly regulates the gene expression of Th1/Th2 type cytokines in transcription level. In addition, DHEAS treatment decreased the hepatic lipid peroxidation and preserved vitamin E level in liver cells. These results suggested that DHEAS could effectively prevent immune dysfunction by regulating cytokine secretion and preventing the oxidative stress in murine AIDS.

Progesterone is necessary for successful pregnancy and had immunosuppressive properties. Peripheral blood mononuclear cells (PBMC) from many women with unexplained recurrent spontaneous abortion responded to trophoblast extract in vitro by prolifertion and releasing soluble, heat-labile factors that are toxic to mouse embryos (embryotoxic factors). Accumulating evidence suggests that T Helper (Th)-1 type immunity to trophoblast is correlated with embryotoxic factor production and is associated with pregnancy loss, while Th2-type immunity is associated with successful gestation. The objective of this study was to determine whether progesterone can inhibit Th1-type cytokine secretion (IFN-${\gamma}$, TNF-${\alpha}$) by trophoblast-activated peripheral blood mononuclear cells from 23 nonpregnant women (age 25-35) with unexplained recurrent abortion (median 5, range 3 to 15)who otherwise produce embryotoxic factors in response to trophoblast. We also determined whether progesterone affected Th2-type cytokines (IL-4, IL-10) in this system in vitro and if IL-10 (1,500 pg/mL) could inhibit Th1-type immunity to trophoblast. IFN-${\gamma}$ was detected in 17 of 23 (74%) trophoblast stimulated PBMC culture supernatants ($77.94{\pm}23.79$ pg/mL) containing embryotoxic activity. TNF-${\alpha}$ was detected in 19 (83%) of these same supernatants ($703.15{\pm}131.36$ pg/mL). In contrast, none of the supernatants contained detectable levels of IL-4 or IL-10. Progesterone ($10^{-5}$, $10^{-7}$, $10^{-9}$M) inhibited Th1-type immunity in a dose dependent manner, but had no effect on Th2-type cytokine secretion. The inhibitory effects of progesterone were abrogated with RU486, but did not affect Th2-type cytokine secretion in trophoblast-activated cell cultures. IL-10, like progesterone also inhibited Th1-type cytokine secretion but had no effect on Th2-type cytokines. These data suggest that therapies designed to suppress Th1-type cytokine secretion in women with recurrent abortion who have evidence of Th1-type immunity to trophoblast may be efficacious in preventing pregnancy loss and should be tested in appropriately designed clinical trials.
