Immune cell-specific expression is one indication of the importance of a gene's role in the immune response. We have compiled a compendium of microarray expression data for virtually all human genes from six key immune cell types and their activated and differentiated states. Immune Response In Silico (IRIS) is a collection of genes that have been selected for specific expression in immune cells. The expression pattern of IRIS genes recapitulates the phylogeny of immune cells in terms of the lineages of their differentiation. Gene Ontology assignments for IRIS genes reveal significant involvement in inflammation and immunity. Genes encoding CD antigens, cytokines, integrins and many other gene families playing key roles in the immune response are highly represented. IRIS also includes proteins of unknown function and expressed sequence tags that may not represent genes. The predicted cellular localization of IRIS proteins is evenly distributed between cell surface and intracellular compartments, indicating that immune specificity is important at many points in the signaling pathways of the immune response. IRIS provides a resource for further investigation into the function of the immune system and immune diseases.

“…BCMA -/-mice are born with no major immune defect apart from impaired survival of some plasma cells in the bone marrow [56]. It has been shown that BCMA binds to TRAF1, 2, and 3 in COS7 fibroblasts [64]. Experiments using TRAF1 -/-, TRAF2 -/-, and TRAF3 -/-plasma cells will be helpful in elucidating the functions of TRAFs in BAFF/BCMA-mediated plasma cell survival.…”

Tumor necrosis factor receptor associated factors (TRAFs) play a variety of interesting and important roles in the regulation of B lymphocyte function. They act both as cytoplasmic regulatory molecules, and as signal transducers for receptors involved in both innate and adaptive humoral immune responses. In this brief review, we highlight the current state of knowledge of the diverse roles of TRAF molecules in the functions of B lymphocytes. CD40CD40 is the most well-studied member of the TNFR superfamily expressed by B lymphocytes, so its interactions with TRAF molecules have also been intensively investigated. B cell CD40 is important in the induction of B cell survival and expansion, immunoglobulin (Ig) production and isotype switching, upregulation of surface molecules involved in B cell antigen presentation, differentiation to B memory cells, and the production of various cytokines (reviewed in [1]. The TRAF molecules have been shown to contribute to each of these functions (reviewed in [2].In 1994, TRAF3 became the first cytoplasmic molecule demonstrated to associate with CD40 (reviewed in [2]). However, for many years, its roles in CD40 signaling were largely unknown, and are still not completely understood. TRAF3 -/-mice die shortly after birth, but adoptive transfer of fetal liver cells from these mice suggested that their B cells were capable of reconstituting the humoral response [3], implying that TRAF3 is not required to promote CD40-mediated antibody responses. This conclusion was supported by experiments in B cell lines demonstrating that inducible overexpression of TRAF3 inhibits both CD40 responses [4], and cooperation between CD40 and the BCR [5]. Subsequently, B cell lines made completely TRAF3-deficient via gene targeting by homologous recombination show no defects in CD40 signaling overall, and display enhanced CD40-mediated c-jun kinase (JNK) activation and IgM production [6]. Recently, mice made conditionally deficient in TRAF3 only in CD19+ B cells show no deficiencies in CD40 signaling in vitro and have enhanced antibody responses [7]. TRAF2 was initially demonstrated to bind CD40 by exogenous overexpression studies in adenocarcinoma cell lines, in which it promotes JNK activation and the activity of NF-κB reporter genes (reviewed in [2]. Because TRAF2 -/-mice have an early lethal phenotype [8],Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers

“…[14][15][16][17] The intracellular domains of BCMA and TACI associate with TNFreceptor-associated factors (TRAFs), leading to activation of NF-kB. 18,19 Recently, another receptor for BLyS, BAFF-R (also called BR3) was identified, which does not bind to APRIL. 20,21 Several lines of evidence indicate that these receptorligand systems crucially contribute to the pathogenesis of the autoimmune diseases.…”

Analysis on the association of human BLYS (BAFF, TNFSF13B) polymorphisms with systemic lupus erythematosus and rheumatoid arthritis

Recent studies indicated a substantial role of BLyS (BAFF, TNFSF13B) in the pathogenesis of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) in humans and in animal models. This study was conducted to screen for polymorphisms of human BLYS, and to examine whether they are involved in the genetic susceptibility to human SLE and RA. A systematic polymorphism screening was performed in the coding region, 5 0 and 3 0 untranslated regions, and promoter region of human BLYS. Association of the detected polymorphisms with SLE and RA was analyzed in 221 Japanese patients with RA, 156 with SLE, and 227 healthy individuals, using the case-control approach. Four single nucleotide polymorphisms (SNPs) in the promoter, one SNP in intron 1, and one rare nonsynonymous substitution (Ala105Thr) in the coding region were detected. The BLYS SNPs were found to form three common haplotypes. Significant association with the susceptibility to SLE or RA was not observed. However, a tendency for the increase of À871T/T genotype was observed in SLE patients with anti-Sm antibody (P ¼ 0.082). BLYS mRNA level was significantly elevated in the monocytes from individuals carrying À871T (P ¼ 0.010). In addition, although statistically not significant, 105Thr allele was slightly increased in patients with RA compared with controls (P ¼ 0.058). Characterizing the functional and clinical significance of these new SNPs requires further study.
