IL-12/IL-12R system in multiple sclerosis 总被引:2,自引:0,他引:2

IL-12/IL-12 receptor (IL-12R) system orchestrates the Th1 pathway of the immune system by maintaining one of the major bridges between innate and adaptive immune responses. Here, we studied both sides of this system in patients with multiple sclerosis (MS) and in controls. MS patients displayed elevated IL-12Rbeta1 and IL-12Rbeta2 expression on PHA-activated T cells compared to healthy subjects. Higher percentages of IL-12Rbeta1 and IL-12Rbeta2 positive T cells in cerebrospinal fluid (CSF) compared to blood were observed both in MS and other neurological diseases (OND). In contrast, numbers of IL-12 secreting blood mononuclear cells (MNC) were similar in MS and controls. The functional importance of high IL-12Rbeta2 in MS was underlined by the finding that IL-12 stimulated IFN-gamma production and proliferation of PHA-activated T cells correlated with levels of IL-12Rbeta2 expression. Our data indicates a dysregulation of the IL-12/IL-12R system in MS. It is suggested that even in the absence of increased IL-12 levels, the net effect of IL-12 might be augmented in MS by elevated expression of its receptor. 相似文献

IL-2 and IL-4 polymorphisms as candidate genes in schizophrenia 总被引:1,自引:0,他引:1
Schwarz MJ Krönig H Riedel M Dehning S Douhet A Spellmann I Ackenheil M Möller HJ Müller N 《European archives of psychiatry and clinical neuroscience》2006,256(2):72-76
An immune process, characterized by a relative
predominance of the T helper–2 (Th2) system and
possibly induced by a viral infection,may be involved in
the pathophysiology of schizophrenia. In this context,
functional polymorphisms in the Interleukin–2 (IL–2)
and Interleukin–4 (IL–4) genes appear to be principal
candidates for genetic schizophrenia research. Further
evidence for these candidate genes comes from several
linkage analyses, pointing to susceptibility gene loci on
chromosomes 4q and 5q, where the genes coding for IL–
2 and IL–4 are located. We carried out a case–control
study including 230 schizophrenic patients and 251
healthy persons, investigating the IL–2 –330 T/G single
nucleotide polymorphism (SNP) and the IL–4 –590 C/T
SNP. A significant association of the IL–2 –330 TT genotype
and of the IL–4 –590 CC genotype with schizophrenia
could be identified. Our findings may partly account
for the relative predominance of the Th2 system in
schizophrenia, although they cannot directly explain
this immunological imbalance, but may be related to an
altered antiviral immune response in patients with
schizophrenia. 相似文献

Interleukin-1 receptor (IL-1R1 and IL-1R2) mRNA expression was detected within the rat hypothalamus, a primary site of IL-1 action, using RT-PCR. Levels of expression were unchanged by cardiac saline-perfusion. However, intracerebroventricular (i.c.v.) administration of IL-1beta caused changes in receptor mRNA expression in non-perfused animals that were profoundly different to those observed in their saline-perfused counterparts. This study demonstrates the importance of perfusing tissue to remove blood cells when determining changes in IL-1 receptor mRNA expression. 相似文献

Differential actions of IL-1 alpha and IL-1 beta in glial cells share common IL-1 signalling pathways 总被引:1,自引:0,他引:1
The cytokine interleukin (IL)-1 plays important roles in peripheral and central inflammation via the actions of two ligands IL-1 alpha and IL-1beta that bind to the IL-1 type I receptor (IL-1RI) and trigger identical responses. However, some recent evidence suggests that IL-1alpha and IL-1beta may have differential actions in the CNS. The aim of this study was to characterise the molecular mechanisms responsible for their differential actions in the brain. We show that, while IL-1alpha and IL-1beta induce identical IL-1 signalling pathways, IL-1beta is significantly more potent than IL-1alpha in stimulating IL-6 release in primary mixed glia. These data suggest that the differential effects of IL-1alpha and IL-1beta on glial cells are mediated by alternative pathways to the classical IL-1 signalling cascade. 相似文献

Theiler’s virus (TMEV) infection of the central nervous system (CNS) induces an immune-mediated demyelinating disease in susceptible mouse strains and serves as a relevant infection model for human multiple sclerosis (MS). The endocannabinoid system represents a novel therapeutic target for autoimmune and chronic inflammatory diseases due to its anti-inflammatory properties by regulating cytokine network. IL-12p70 and IL-23 are functionally related heterodimeric cytokines that play a crucial role in the pathogenesis of MS. In the present study we showed that the endocannabinoid anandamide (AEA) downregulated the gene expression of IL-12p70 and IL-23 forming subunits mRNAs in the spinal cord of TMEV-infected mice and ameliorated motor disturbances. This was accompanied by significant decreases on the serological levels of IL-12p70/IL-23 and more interestingly, of IL-17A. In contrast, serum levels of IL-10 resulted elevated. In addition, we studied the signalling pathways involved in the regulation of IL-12p70/IL-23 and IL-10 expression in TMEV-infected microglia and addressed the possible interactions of AEA with these pathways. AEA acted through the ERK1/2 and JNK pathways to downregulate IL-12p70 and IL-23 while upregulating IL-10. These effects were partially mediated by CB2 receptor activation. We also described an autocrine circuit of cross-talk between IL-12p70/IL-23 and IL-10, since endogenously produced IL-10 negatively regulates IL-12p70 and IL-23 cytokines in TMEV-infected microglia. This suggests that by altering the cytokine network, AEA could indirectly modify the type of immune responses within the CNS. Accordingly, pharmacological modulation of endocannabinoids might be a useful tool for treating neuroinflammatory diseases. 相似文献
