Project description:Systemic lupus erythematosus is a chronic autoimmune disease with multifactorial ethiopathogenesis. The complement system is involved in both the early and late stages of disease development and organ damage. To better understand autoantibody mediated complement consumption the GAPAID consortium examined ex vivo immune complex formation on autoantigen arrays. We recruited patients with SLE (n=211), with other systemic autoimmune diseases (n=65) and non-autoimmune control subjects (n=149) in two rheumatology tertiary care centers. Standard clinical and laboratory data were collected from all subjects and serum complement levels were determined in SLE patients. The genotype of SNP rs1143679 in the ITGAM gene was also determined. On-chip formation of immune complexes was examined using a functional immunoassay on autoantigen microarray. The amount of antigen-bound IgM, IgG and complement C4 and C3 was quantified on autoantigens comprising nucleic acids, proteins and lipids. Our results show that the relatively high complement consumption of nucleic acids is further increased upon binding of IgM and IgG. This is true even when serum complement levels are decreased due to complement consumption in SLE patients. A negative correlation between serum complement levels and ex vivo complement deposition on nucleic acid autoantigens is demonstrated. On the contrary, most protein and lipid autoantigens show positive correlation with C4 and C3 levels. Genetic analysis reveals that the non-synonymous variant rs1143679 in complement receptor type 3 is associated with an increased production of anti-dsDNA IgG antibodies. Notwithstanding, homozygous carriers of the previously reported susceptible allele (AA) have lower levels of dsDNA specific IgM among SLE patients. Regarding organ involvement we find that besides anti-C1q IgG, low levels of dsDNA specific IgM and low complement C4 binding to C1q are also associated with renal injury. In summary, nucleic acids maintain a skewed complement deposition balance when bound by IgG and IgM, depleting the early classical complement pathway from other physiological processes. Dysfunction of the receptor responsible for complement-mediated apoptotic debris removal promotes the development of autoantibodies targeting nucleic acids. These observations provide serological and genetic evidence for complement-mediated clearance deficiency of apoptotic debris in lupus.

Project description:To investigate c-Maf-controlled gene expression, M2-like bone marrow-derived macrophages (BMM) were transfected with c-Maf or control siRNA. Knockdown of c-Maf significantly decreased c-Maf protein and mRNA expression levels. In addition, IL-10 and arginase mRNA levels were significantly decreased while IL-12 was increased. In contrast, ectopic expression of c-Maf in the M1-like BMM significantly upregulated IL-10 and arginase mRNA expression levels while downregulated IL-12 expression level, suggesting an M2-like phenotype. These data indicate that c-Maf may be a critical controller in regulating M2-related gene expression. To further determine which part of the M2 macrophage transcriptomic profile is controlled by c-Maf, we performed microarray analysis using polarized M2-like BMM from WT or c-Maf KO fetal liver chimeric mice. Notably, many M2 genes were differentially regulated by c-Maf. Further real-time PCR (qPCR) analysis confirmed that the mRNA expression levels of IL-12, IL-1β, IL-6, arginase, IL-10, VEGF, TGF-β, IRF-4, and CCR2 were significantly altered in c-Maf-deficient M2 BMM. Since M2-like macrophages have a potent immunosuppressive function on T cell activation, we next determined whether deficiency of c-Maf in M2 BMM would reverse such effect. M2 BMM from WT mice exhibited potent immunosuppressive activity as IFN-γ production from antigen (Ag)-specific CD4 and CD8 T cells was significantly diminished. In contrast, c-Maf deficiency in M2 BMM significantly increased IFN-γ production by CD4 and CD8 T cells compared to WT M2 BMM. These data suggest that c-Maf not only controls many M2-related gene expression but also is critical in regulating M2-like macrophage-mediated T cell immunosuppression.

Project description:In 2013, two large-scale Florida manatee (Trichechus manatus latirostris) mortality episodes were reported on separate coasts of Florida. The east coast mortality episode was associated with an unknown etiology in the Indian River Lagoon (IRL). The west coast mortality episode was attributed to a persistent Karenia brevis algal bloom or ‘red tide’ centered in Southwest Florida. To investigate these two mortality episodes, proteomic experiments using two-dimensional difference gel electrophoresis (2D-DIGE) followed by protein identification using liquid chromatography-tandem mass spectrometry (LC-MS/MS) were conducted, along with a separate gel-free analysis using isobaric tags for relative and absolute quantification (iTRAQ) LC-MS/MS. In comparison to the control group, manatees from the IRL, an area associated with an unknown mortality episode, displayed increased levels of several proteins in their serum samples. These increased proteins, which were identified in the iTRAQ experiment, included kininogen-1 isoform 1 (average ratio 1.38), protein AMBP (1.38), histidine-rich glycoprotein (1.34), properdin (1.30), and complement C4-A isoform 1 (1.25). In the red tide group, ceruloplasmin (2.32), pyruvate kinase isozymes M1/M2 isoform 3 (2.29), angiotensinogen (2.08), complement C4-A isoform 1 (1.83), and complement C3 (1.42) were increased. The proteins kininogen-1 isoform 1, histidine-rich glycoprotein, complement C4-A isoform 1, angiotensinogen, and complement C3 were also identified in increased levels in the 2D-DIGE experiment (Table 2b). These proteins are associated with acute-phase response, amyloid formation and accumulation, copper and iron homeostasis, the complement cascade pathway, and other important cellular functions. The increased level of complement C4 protein observed in both the red tide and unknown mortality episode groups was confirmed through the use of Western Blot.

Project description:Insomnia is an economic burden and public health problem. This study aimed to explore potential biological pathways and protein networks for insomnia characterized by wakefulness after sleep. Proteomics analysis was performed in the insomnia group with wakefulness and the control group. The differentially expressed proteins (DEPs) were enriched, then hub proteins were identified by protein-protein interaction (PPI) network and verified by parallel reaction monitoring (PRM). Compared with the control group, the sleep time and efficiency of insomnia patients were decreased, awakening time and numbers after sleep onset were significantly increased (P < 0.001). The results of proteomic sequencing found 68 DEPs in serum under 1.2-fold changed standard. These DEPs were significantly enriched in humoral immune response, complement and coagulation cascades, cholesterol metabolism. Through PPI network, we identified 10 proteins with the highest connectivity as hub proteins. Among them, differential expression of 9 proteins was verified by PRM.We identified the hub proteins and molecular mechanisms of insomnia patients characterized by wakefulness after sleep. It provided potential molecular targets for the clinical diagnosis and treatment of these patients, and indicated the immune and metabolic systems may be closely related to insomnia characterized by wakefulness after sleep.

Project description:The gastrointestinal nematode Ostertagia ostertagi is one of major causal agents that contribute to production inefficiency in cattle industry in the temperate region of the world. One of pathophysiological factors that lead to reduced weight gain and milk yield is altered gastrointestinal functions, resulting from considerable tissue damage in the abomasal mucosa during infections. Protective immunity to Ostertagia ostertagi infections in cattle develops very slowly. Resistance to reinfection becomes manifest only after a prolonged period of exposure. Mechanisms underlying the development of protective immunity remain largely unexplored. Immune animals, with significantly reduced worm burdens, were developed after multiple drug-attenuated experimental infections and were compared to the primary infected group and their respective uninfected controls. In this study, transcriptomic analysis identified 3 signaling pathways, the complement system, leukocyte extravasation and acute phase responses, significantly impacted during both primary and repeat infections. The markedly increased mRNA levels of complement components C3, factor B (CFB), and factor I (CFI) in the abomasal mucosa of the infected cattle were confirmed using quantitative PCR. Western blot analysis established the presence of elevated levels of activated C3 proteins in the mucosa. One of the iniators of local complement activation could be related with secretory IgA and IgM because infections significantly upregulated expression of J chain (IGJ) as well as polymeric Ig receptor (PIGR) and an IgM-specific receptor (FAIM3), suggesting sustained increase in both synthesis and transepithelial transport of IgA and IgM during the infection. The elevated levels of pro-inflammatory cytokines, such as IL-4 and IL-1β, during the infection may be involved in gene regulation of complement components. Our data suggested enhanced tissue repair and mucin secretion in immune animals may also contribute to protective immunity. Our results presented the first piece of evidence that local complement activation may be involved in the development of long term protective immunity and provided a novel mechanistic insight into resistance against Ostertagia ostertagi in cattle. There were four treatment groups: naive control (never infected), primary infection, drug-attenuated control, and drug-attenuated 5th reinfection. Each group had 4 biolgical replicates. A total of 16 arrays were used for this experiment. The 2 major contrast were 1). The primary infection vs naive control; and 2). The drug-attenuated 5th reinfection vs the drug-attenuated control.

Project description:Background Immunosuppressants and renal ischemia-reperfusion injury (IRI) are risk factors for BK polyomavirus infection after kidney transplantation. However, the mechanism remains unclear. Methods We used a model of mouse polyomavirus (MPyV) infection to investigate the mechanism of IRI and immunosuppressants to promote polyomavirus replication. Results After primary infection, MPyV established persistent infection in the kidneys until week 9 and subsequently were significantly increased by IRI or immunosuppressants treatment individually. In IRI group, viral loads peaked on day 3 in the left kidney, which were significantly higher than that in the right kidney and the control group, and then gradually decreased. In immunosuppressants group, viral loads increased on day 3 without significant difference between left and right kidney, which were significantly higher than that in the control group, and then maintained at high levels. Protein-protein interaction network analysis screened complement C3, EGFR, and FN1 as core genes. Pathway enrichment analysis based on the IRI or immunosuppressants related genes selected by WGCNA indicated that NF-?B signaling pathway was the main pathway involved in promoting MPyV replication. We further confirmed our findings using published datasets GSE47199 and GSE75693. Conclusions Our study demonstrated that IRI and immunosuppressants promote polyomavirus replication through common molecular mechanisms.
