Autoantigen Microarray for High-throughput Autoantibody Profiling in Systemic Lupus Erythematosus

Systemic lupus erythematosus(SLE) is a complex autoimmune disease characterized by the production of autoantibodies to a broad range of self-antigens. Profiling the autoantibody repertoire using array-based technology has emerged as a powerful tool for the identification of biomarkers in SLE and other autoimmune diseases. Proteomic microarray has the capacity to hold large number of self-antigens on a solid surface and serve as a high-throughput screening method for the determination of autoantibody specificities. The autoantigen arrays carrying a wide variety of self-antigens, such as cell nuclear components(nucleic acids and associated proteins), cytoplasmic proteins, phospholipid proteins, cell matrix proteins, mucosal/secreted proteins, glomeruli, and other tissue-specific proteins, have been used for screening of autoantibody specificities associated with different manifestations of SLE. Arrays containing synthetic peptides and molecular modified proteins are also being utilized for identification of autoantibodies targeting to special antigenic epitopes. Different isotypes of autoantibodies, including Ig G, Ig M, Ig A, and Ig E, as well as other Ig subtypes, can be detected simultaneously with multi-color labeled secondary antibodies. Serum and plasma are the most common biologic materials for autoantibody detection, but other body fluids such as cerebrospinal fluid, synovial fluid, and saliva can also be a source of autoantibody detection.Proteomic microarray as a multiplexed high-throughput screening platform is playing an increasingly-important role in autoantibody diagnostics.In this article,we highlight the use of autoantigen microarrays for autoantibody exploration in SLE.     

Novel Autoantibodies Related to Cell Death and DNA Repair Pathways in Systemic Lupus Erythematosus

Systemic lupus erythematosus(SLE) is a complex autoimmune syndrome characterized by various co-existing autoantibodies(auto Abs) in patients' blood.However,the full spectrum of auto Abs in SLE has not been comprehensively elucidated.In this study,a commercial platform bearing 9400 antigens(Proto Array) was used to identify auto Abs that were significantly elevated in the sera of SLE patients.By comparing the auto Ab profiles of SLE patients with those of healthy controls,we identified 437 Ig G and 1213 Ig M auto Abs that the expression levels were significantly increased in SLE(P 0.05).Use of the Proto Array platform uncovered over 300 novel auto Abs targeting a broad range of nuclear,cytoplasmic,and membrane antigens.Molecular interaction network analysis revealed that the antigens targeted by the auto Abs were most significantly enriched in cell death,cell cycle,and DNA repair pathways.A group of auto Abs associated with cell apoptosis and DNA repair function,including those targeting APEX1,AURKA,POLB,AGO1,HMGB1,IFIT5,MAPKAPK3,PADI4,RGS3,SRP19,UBE2 S,and VRK1,were further validated by ELISA and Western blot in a larger cohort.In addition,the levels of auto Abs against APEX1,HMGB1,VRK1,AURKA,PADI4,and SRP19 were positively correlated with the level of anti-ds DNA in SLE patients.Comprehensive auto Ab screening has identified novel auto Abs,which may shed light on potential pathogenic pathways leading to lupus.

Expression of CD45 and proliferative response to CD3 as suitable classification markers of patients with gastric adenocarcinoma

25 patients with resectable gastric adenocarcinoma, subdivided according to the absence or presence of residual neoplasic disease (RND− or RND+, respectively), were studied. Cytofluorometric analysis and proliferative responses to mitogens was performed in peripheral blood mononuclear cells of patients. When compared to healthy subjects, the percentage of CD3-expressing cells was significantly reduced in both groups of patients studied (p<0.0001 in all instances). However, when CD45 is considered instead of (CD3, its expression is found to be significantly reduced only in the RND+ patients (72%±11), when compared with the control group (96±1%, p<0.0001). Likewise, cells from these patients significantly less proliferated when stimulated with monoclonal antibodies to CD3 than control cells (18,920±6,019 cpm vs. 42,697±1,798 cpm, p=0.0036); a difference not found if RND− patients (33,619±11,733 cpm) were considered. We propose that the low expression of CD45 and the poor response to CD3 are markers that are able to identify the subgroup of patients in whom the disease will tend to progress more rapidly.We also suggest the use of such markers as additional criteria for the classification of patients with gastric adenocarcinoma or to identify patients who require more aggressive therapeutic strategies.     

护理干预对系统性红斑狼疮患者激素治疗依从性的影响

系统性红斑狼疮患者血清中IL-17 的检测及临床意义

目的:通过检测系统性红斑狼疮(SLE)患者外周血中IL-17的水平,探讨其临床意义。方法:用酶联免疫吸附法(enzymelinked immunosorbent assay,ELISA)检测61例SLE患者及30例健康人血清IL-17水平,并收集整理SLE患者的临床资料及实验室数据,分析其与临床的关系。结果:活动期SLE患者血清IL-17水平明显高于正常对照组(P<0.01),与SLE非活动组相比,差异亦有统计学意义(P<0.01)。但SLE非活动组与正常对照组间无统计学意义。结论:IL-17水平在活动期SLE患者血清中表达明显增高,且与SLEDAI评分呈正相关,提示IL-17可能参与了SLE疾病的病理过程,可能与疾病活动的关系密切。

CD45 variant alleles: possibly increased frequency of a novel exon 4 CD45 polymorphism in HIV seropositive Ugandans

The CD45 (leucocyte common) antigen is a haemopoietic cell specific tyrosine phosphatase essential for antigen receptor signalling in lymphocytes, and expression of different CD45 isoforms is associated with distinct functions. Here we describe a novel polymorphism in exon 4 (A54G) of the gene encoding CD45 (PTPRC) that results in an amino acid substitution of Thr-19 to Ala in exon 4. The 54G allele was identified in African Ugandan populations and was found with a suggestive but not statistically significant increase in frequency amongst HIV-seropositive Ugandans. This suggests that the 54G variant and CD45 splicing abnormalities might be associated with HIV infection.

目的: 探讨高分压氧下淋巴细胞内酪氨酸磷酸酶SHP-1和CD45功能状态的变化.方法: 分别用能引起功能发生不同变化的高分压氧处理淋巴细胞,检测细胞内酪氨酸磷酸酶SHP-1和CD45的催化活性、蛋白量及蛋白磷酸化水平.结果: 经各压力-时程的高分压氧处理后,SHP-1的活性均降低;而CD45仅在具有抑制细胞功能的氧剂量处理后其活性才降低.两种酶的蛋白表达量及酪氨酸磷酸化水平没有发生显著变化.结论: 高分压氧下SHP-1和CD45活性降低可能是由于酶结构受增多的活性氧破坏引起;SHP-1和CD45可能是所选高分压氧方案引起淋巴细胞功能变化的作用位点.     

Genomic organization of the channel catfish CD45 functional gene and CD45 pseudogenes

CD45 is a transmembrane protein tyrosine phosphatase, which in mammals plays an important role in T and B cell receptor and cytokine signaling. Recently, a catfish cDNA was shown to contain all characteristic CD45 features: an alternatively spliced amino-terminus, a cysteine-rich region, three fibronectin domains, a transmembrane region, and two phosphotyrosine phosphatase domains. However, analyses of CD45 cDNAs from various catfish lymphoid cell lines demonstrated that catfish CD45 is unique in that it contains a large number of alternatively spliced exons. Sequence analyses of cDNAs derived from the catfish clonal B cell line 3B11 indicated that this cell line expresses up to 13 alternatively spliced exons. Furthermore, sequence similarity among the alternatively spliced exons suggested duplication events. To establish the exact number and organization of alternatively spliced exons, a bacterial artificial chromosome library was screened, and the catfish functional CD45 gene plus six CD45 pseudogenes were sequenced. The catfish functional CD45 gene spans 37 kb and contains 49 exons. In comparison, the human and pufferfish CD45 genes consist of 34 and 30 exons, respectively. This difference in the otherwise structurally conserved catfish gene is due to the presence of 18 alternatively spliced exons that were likely derived through several duplication events. In addition, duplication events were also likely involved in generating the six pseudogenes, truncated at the 3 ends. A similarly 3 truncated CD45 pseudogene is also present in the pufferfish genome, suggesting that this specific CD45 gene duplication occurred before catfish and pufferfish diverged (400 million years ago).
