Endotoxin-induced cytokine gene expression in vivo. II. Regulation of tumor necrosis factor and interleukin-1 alpha/beta expression and suppression.

Tumor necrosis factor alpha (TNF alpha) mRNA is present in a preformed intracellular pool in the spleen, liver, and small bowel of naive rats. Endotoxin (Salmonella typhus lipopolysaccharide) injected intravenously induces little or no increase in whole-organ TNF mRNA levels at 15', 30', 1 degree, 2 degrees, or 4 degrees, whereas serum TNF levels are markedly elevated at 1 and 2 hours. Dexamethasone pretreatment of rats suppresses LPS-induced serum TNF concentrations, but does not suppress TNF mRNA levels in the spleen or bowel. Tachyphylaxis experiments demonstrate that a second injection of endotoxin 2 hours after an initial injection fails to induce a second peak of serum TNF, although TNF mRNA levels in the spleen and bowel remain at the levels found in naive rats. Corynebacterium parvum upregulates endotoxin-induced serum TNF release and intravenous injection of IL-1 induces the release of serum TNF but neither alters whole-organ TNF mRNA levels. Interleukin-1 alpha (IL-1 alpha) mRNA was not constitutively detected in whole-organ RNA preparations of the spleen, liver, and small bowel of naive rats. Endotoxin induces IL-1 alpha mRNA most easily appreciated in the spleen beginning at 1 hour, peaking at 2 to 4 hours, and disappearing by 6 hours. Interleukin-1 beta (IL-1 beta) mRNA was not constitutively detected in the organs examined or was present in small amounts. Endotoxin induces IL-1 beta mRNA beginning at 0.5 hours, peaking at 1 hour, and disappearing by 6 hours. Dexamethasone pretreatment prevents the LPS-induced appearance of IL-1 alpha mRNA and suppresses but does not completely inhibit the appearance of IL-1 beta mRNA. C. parvum upregulates endotoxin-induced IL-1 mRNA expression. Intravenous injection of TNF or IL-1 both induce IL-1 mRNA expression. In conclusion, TNF mRNA is constitutively expressed and TNF mRNA levels as analyzed in whole-organ RNA preparations do not change in concert with serum TNF protein levels during conditions of endotoxemia, dexamethasone treatment, tachyphylaxis, priming with C. parvum, or after injection of IL-1. In contrast, IL-1 mRNA expression during endotoxemia, dexamethasone treatment, priming with C. parvum, or after injection of TNF or IL-1 shows clear increases and decreases in whole-organ RNA preparations.     

Role of biphasic changes in splenic dendritic cell activity in a mouse model of multiple organ dysfunction syndrome

To analyze the changes in splenic dendritic cell (DC) activity and serum cytokine levels during the progression of multiple organ dysfunction syndrome (MODS). A C57BL/6 mouse model of MODS was established by intraperitoneal injection of zymosan. Immunohistochemistry and flow cytometry were used to detect expression of I-A^b (MHC-II molecules of mice) as well as co-stimulatory and co-inhibitory molecules in spleen and DC surface. The levels of various cytokines in serum and spleen tissue were analyzed 6 h, 12 h, 24 h, 48 h, 5 d and 12 d after injury. Death occurred at 24-48 h and 10-12 d after injury. The expression of I-A^b and CD86 in spleen tissue and on DCs increased 6-12 h after injury, followed by gradual reduction and at 12 d. The inhibitory molecule, PD-L1, was expressed on normal DCs, but expression of PD-1 was undetectable. PD-L1 and PD-1 expression increased and remained high at 5 d and 12 d after injury. In addition, TNF and IL-1 levels increased 6-12 h after injury; HMGB1 and IL-10 levels increased 24 h and 5 d after injury, respectively. In contrast, IL-2 and IL-12 decreased with disease progression. At 12 d after injury, proinflammatory and anti-inflammatory cytokine levels remained high, while IL-2 and IL-12 were significantly reduced. IL-10 and IL-12 changes in spleen were consistent with those in serum. MODS progression was characterized by changes in splenic DC activity as well as altered serum pro-inflammatory and anti-inflammatory cytokine levels, suggesting early immune activation and predominant immune tolerance at the late stage.     

Superantigen activation and kinetics of cytokines in the Long-Evans rat.

This study was conducted to identify and quantify, over time, selected cytokine responses in Long-Evans rats that were exposed to staphylococcus enterotoxin B (SEB). The kinetics of selected cytokines [interleukin-2 (IL-2), IL-6, interferon-gamma (IFN-gamma) and tumour necrosis factor (TNF)] and phenotype and cell cycle analysis of T lymphocytes were determined in Long-Evans rats administered a single intraperitoneal (i.p.) dose of either 50 microg or 500 microg of SEB. Rats injected with 50 microg SEB had significantly elevated levels of IL-2, IL-6 and IFN-gamma in their serum 2 hr post-injection. IL-2 serum levels were significantly elevated at 2 hr and returned to near control values by 12 hr while both IL-6 and IFN-gamma peaked at 6 hr but remained significantly increased at 24 hr post SEB exposure. A 500 microg dose of SEB did not further enhance these cytokine responses. When spleen cells were collected for culture 2 hr after rats were injected i.p. with 50 microg SEB and cocultured with SEB, TNF and IL-6 levels were significantly increased after 2 hr incubation, while IL-2 and IL-6 were significantly elevated at 6 hr. Production of all these cytokines in spleen cell cultures continued to increase over the 24 hr sampled. Peritoneal cells were collected for culture either at 1 hr or 2 hr after injection of either 50 microg or 500 microg of SEB. IL-6 was significantly increased after 1 hr in culture while TNF was significantly increased by 2 hr regardless of whether the cells were harvested 1 or 2 hr after SEB injection. The greatest response for both IL-6 and TNF occurred when cells from animals injected with 50 microg SEB were restimulated in vitro with SEB. The peak levels for IL-6 were at 12 hr post SEB exposure while TNF peaked at 6 hr. The percentage of CD4+ cells was significantly increased at 48 hr and 72 hr post SEB (50 microg) administration while the percentage of CD8+ cells remained similar to control values for the 168-hr test period. A similar pattern was observed in cell cycling where the CD4+ cells proliferated up to 2 days post SEB injection and then were significantly suppressed at day 3. The CD8+ cells were comparable to control values. These studies demonstrate that the cytokine responses in Long-Evans rats exposed to a superantigen are somewhat similar to those that occur in mice and humans, e.g. a rapid short increase in the production of IFN-gamma and TNF that was accompanied by an increase in the production of IL-2. Additional responses noted in this species, however, were a marked increase in IL-6 production, as well as an early increase in the number and cycling of CD4+ cells followed by a down-regulation of these events. These activities occurred in the absence of notable histopathological alteration of lymphoid organs. The results indicate that the Long-Evans rat is an acceptable animal model to investigate the pathogenesis of superantigen-induced disease and that IL-6 may be an active mediator of this process.     

Effects of the Japanese Herbal Medicine “Sho-saiko-to” (TJ-9) on Interleukin-12 Production in Patients with HCV-Positive Liver Cirrhosis

Interleukin-12 (IL-12) is an important cytokine for maintainence of normal systemic defense and bioregulation. The Japanese herbal medicine Sho-saiko-to (TJ-9) has been administered to 1.5 million Japanese patients with chronic liver diseases. TJ-9 is known to significantly suppress cancer development in the liver and has macrobiotic effects. In the present study, we examined the in vitro production of IL-12 by circulating mononuclear cells from liver cirrhosis patients and the effects of TJ-9 on IL-12 production.The monocyte/macrophage fraction and the lymphocyte fraction of peripheral blood were obtained from 11 HCV-positive liver cirrhosis patients and 12 healthy subjects. Interleukin-12 levels in the supernatants were measured using ELISA kits. The levels of IL-12 produced by the patients fractions were significantly lower than those produced by healthy subjects (p < 0.01, p < 0.05). However, when TJ-9 was added to the cultures, the IL-12 production levels in both cell fractions increased approximately three fold, and the levels from the monocyte/macrophage fraction were almost the same as those from healthy subjects. This effect of TJ-9 was attributable to two of its seven herb components, that is, scutellaria root and glycyrrhiza root. One possible mechanism for the macrobiotic effects of TJ-9 on liver cirrhosis patients may be the improvement in IL-12 production.     

Increased IL-18 levels in seminal plasma of infertile men with genital tract infections

PROBLEM: Interleukin (IL)-18 is a novel cytokine, previously known as interferon (IFN)-gamma inducing factor. We evaluated the levels of IL-18 and IFN-gamma in seminal plasma (SP) of fertile and infertile men. METHOD OF STUDY: Semen samples were obtained by masturbation from 80 men, and were examined for the levels of IL-18 and IFN-gamma by enzyme-linked immunosorbent assay. Seven groups were included: (i) fertile men (n = 18), (i) infertile men with genital tract infections (n = 17), (iii) with varicocele (n = 15), (iv) with Klinefelter syndrome (n = 6), (v) with cryptorchidism (n = 7), (vi) with mumps orchitis (n = 7), and (vii) with idiopathic testicular lesions (n = 10). RESULTS: Mean levels of IL-18 were higher in SP from infertile men with genital tract infections compared with SP from other groups except Klinefelter syndrome (P < 0.05). However, no significant differences could be detected for IFN-gamma. A significant positive correlations was found between IL-18 and IFN-gamma in total patient population (P < 0.001). Moreover, a negative correlation was observed between IL-18 and sperm concentrations, and motility (P < 0.01 and < 0.03, respectively). Furthermore, there was a positive and statistically significant association between IL-18 and IFN-gamma levels in SP of infertile men with genital tract infections (P < 0.0001). However, there was no relationship between IL-18 and IFN-gamma, and semen parameters in the same group. CONCLUSION: SP IL-18 levels were increased in men with urogenital infections. Thus, the elevated expression of IL-18 in SP may be used as a diagnostic marker in the male genital tract infections.     

Alterations in interleukin-6 production by LPS- and Con A-stimulated mixed splenocytes,spleen macrophages and lymphocytes in prenatally diazepam-exposed rats

Prenatal exposure to diazepam leads to a suppression of mitogen or allogen-induced lymphocyte proliferation as well as to a reduced production of tumour necrosis factor (TNF)- from rat splenocytes during postnatal development of rats. We analysed the secretion of interleukin (IL)-6 which occurs at a later stage of the cytokine cascade. Splenocytes of male offspring from Long Evans rats, treated with a daily dose of diazepam (1.25 mg/kg) from gestational day 14 to 20, were stimulated with lipopolysaccaride (LPS) and concanavalin A (Con A). In response to LPS, IL-6 liberation was significantly lower in mixed splenocytes and spleen macrophages of 2 and 8 week old prenatally diazepam-treated rats than in controls. Spleen lymphocyte preparations of prenatally treated animals exhibited a reduction of IL-6 release at 12 h and an increase at 24 h of incubation. At 2 weeks of age, Con A-induced IL-6 production could only be detected in mixed splenocytes; prenatally treated rats were releasing significantly less IL-6 than controls. In 8 week old rats, IL-6 liberation from mixed splenocytes and spleen macrophages was significantly lower in prenatally treated animals than in controls. Spleen lymphocytes presented a complex response picture depending upon incubation conditions. Our data indicate that in prenatally diazepam-exposed rats, the disturbance of cytokine release also extends to cytokines which play an important role in the later phases of immune responses.     

Association between gene polymorphisms of IL-12, IL-12 receptor and IL-27 and organ involvement in Iranian endometriosis patients

Endometriosis is an inflammatory disease characterized by the presence of ectopic endometrial tissue, immune cell dysfunction and abnormal cytokine secretion. In addition to immunological factors, genetic variations that influence endometriosis severity and cytokine expression levels play important roles in the pathogenesis of this disease. Interleukin-12 (IL-12), specifically its p40 subunit encoded by IL-12B gene and the interleukin-12 receptor β1 (IL-12Rβ2) chain of its receptor, as well as interleukin-27 (IL-27) are important in the establishment of endometriosis. So, in this study, we measured IL-12 and IL-27 serum levels and investigated the possible links between IL-12B rs3212227, IL-12Rβ2 rs3790565 and IL-27 rs153109 polymorphisms and the risk of developing endometriosis in a group of Iranian women. In this case-control study, 162 endometriosis patients and 151 healthy women were included and tested for the aforementioned polymorphisms using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The enzyme-linked immunosorbent assay (ELISA) method was also used to measure IL-12 and IL-27 serum levels. Although there was no statistically significant association between the genotypes and alleles of the studied polymorphisms and the development of endometriosis in general, the AA genotype of IL-12B rs3212227 showed a significant association with uterine endometriosis when compared to AC+CC genotypes (p = .04, CI = 0.270–0.988, OR = 0.517). Indeed, the AA genotype of the IL-12B rs3212227 single nucleotide polymorphism (SNP) may be linked with a lower risk of developing uterine endometriosis. There was no significant difference in IL-27 levels between the two studied groups (p = .49), and IL-12 levels were undetectable in both groups. In conclusion, the AA genotype of IL-12B rs3212227 might be associated with a decreased risk of uterine involvement in endometriosis patients.

IL-27 plasma level in relapsing remitting multiple sclerosis subjects: The double-faced cytokine

Interleukin-27 (IL-27) is a member of IL-6/IL-12 cytokine family which possesses pro- and anti-inflammatory properties and participates in the pathogenesis of various autoimmune diseases. In our case-control study, plasma was collected from healthy subjects as control group (n = 40) and patients with relapsing-remitting multiple sclerosis (RRMS) (n = 40), including new identified cases without treatment (n = 12) and those treated with Interferon beta (IFN-β) (n = 28). The plasma level of IL-27 was assessed by ELISA method. Our results indicated that plasma level of IL-27 in MS patients increased significantly compared to the control subjects (P = 0.027). Furthermore, after parting case group into the two sub-groups, results revealed a significant difference of IL-27 plasma levels between control group and treated patients (P < 0.001), but not about that of between healthy subjects and untreated MS patients (P = 0.259). Also, mean levels of IL-27 in treated and untreated patients showed a significant difference (P = 0.007). These results demonstrate the possible modulation of IL-27 during autoimmune disease in human which may suggest the suppressive or therapeutic role of IL-27 on inflammatory diseases.
