Description
Islet leukocytic infiltration (insulitis) is first obvious at around 4 weeks of age in the NOD mouse a model for human type 1 diabetes (T1DM). The molecular events leading to insulitis are poorly understood. Since TIDM is caused by numerous genes, we hypothesized that multiple molecular pathways are altered and interact to initiate this disease.

Description
Type 1 diabetes is a multigenic disease caused by T-cell mediated destruction of the insulin producing -cells. Although conventional (targeted) approaches of identifying causative genes have advanced our knowledge of this disease, many questions remain unanswered. Using a whole molecular systems study, we unraveled the genes/molecular pathways that are altered in CD4 T-cells from young NOD mice prior to insulitis (lymphocytic infiltration into the pancreas). Many of the CD4 T-cell altered genes lie within known diabetes susceptibility regions (Idd), including several genes in the diabetes resistance region Idd13 and two genes (Khdrbs1 and Ptp4a2) in the CD4 T-cell diabetogenic activity region Idd9/11. Alterations involved apoptosis/cell proliferation and metabolic pathways (predominant at 2 weeks), inflammation and cell signaling/activation (predominant at 3 weeks), and innate and adaptive immune responses (predominant at 4 weeks). We identified several factors that may regulate these abnormalities: IRF-1, HNF4A, TP53, BCL2L1 (lies within Idd13), IFNG, IL4, IL15, and prostaglandin E2, which were common to all 3 ages; AR and IL6 to 2 and 4 weeks; and Interferon (IFN-I) and IRF-7 to 3 and 4 weeks. Others were unique to the various ages (e. g. MYC, JUN, and APP to 2 weeks; TNF, TGFB1, NFKB, ERK, and p38MAPK to 3 weeks; and IL12 and STAT4 to 4 weeks). Our data suggest that diabetes resistance genes in Idd13 and Idd9/11, and BCL2L1, IL6-AR and IFNG-IRF-1-IFN-I/IRF-7-IL12 pathways play an important role in CD4 T-cells in the early pathogenesis of autoimmune diabetes. Thus, the alternative approach of investigation at the molecular systems level has captured new information, which combined with validation studies, offers the opportunity to test hypotheses on the role played by the genes/molecular pathways identified in this study, to understand better the mechanisms of autoimmune diabetes in CD4 T-cells, and to develop new therapeutic strategies for the disease.

Description
Rheumatoid arthritis (RA) is a heterogeneous disease with clinical and biological polymorphisms. However, little is known about baseline molecular variations among individual RA patients. The purpose of this study was to address this issue using F2 intercross mice generated from arthritis-prone BALB/c and arthritis-resistant DBA/1 mice deficient for interleukin 1 receptor antagonist (Il1rn). Two distinct subpopulations of arthritic mice were identified in the 38 mice studied. One subgroup of diseased mice was characterized by myeloid cell dominant inflammation, whereas the other was mainly associated with increased anti-apoptotic activities of inflammatory cells.

Description
We perform microarray analysis of HUVECs upon stimulation with virulent wildtype C. albicans strain SC5314 or its efg1/efg1 cph1/cph1 hyphal-deficient derivative strain CAN34 to compare the gene expression profiles elicited from HUVECs in response to these strains. In addition, these responses are compared to that of TNF-alpha induced responses to determine which responses are Candida-specific.

Description
Rheumatoid arthritis (RA), one of the most common polygenic diseases, is characterized by a chronic, progressive inflammation mainly in joints and has an unknown etiology. Numerous studies have revealed the significance of cytokines TNF and IL-1 in the onset and progression of RA. Due to the complexity of interactions among different cytokines and immune cells, little is known about the precise molecular mechanisms underlying RA. In this study, oligonucleotide microarray analysis and a mouse model of RA, IL-1 receptor antagonist deficient mice were used to address this issue. Two hundred and ninety transcripts were found to be dysregulated greater than or equal to 2-fold in the diseased mice. Phase-specific gene expression changes were identified, including early increase and late decrease of heat shock protein coding genes and Cyr61. Moreover, common gene expression changes were also observed, especially the upregulation of paired-Ig-like receptor A (Pira) in both early and late phases of arthritis. We conclude that common and distinct gene expression change patterns that were identified globally may represent novel opportunities for better control of RA through early diagnosis and development of alternative therapeutic strategies.

Description
Although activated CD4+ T cell-driven overproduction of cytokines, especially TNF and IL1, is generally regarded as the major factor in the development of rheumatoid arthritis (RA), little is known about the precise role of CD4+ T cells in the initiation and progression of this disease. In this study, this issue was addressed using a time-course microarray analysis in a mouse model of RA, Il1rn deficient mice.No obvious cytokine gene expression changes reflecting T cell activation was observed in CD4+ T cells in the Il1rn deficient mice during the course of spontaneous arthritis. On the contrast, majority of dysregulated genes were those predominantly expressed in myeloid lineage cells, suggesting T cell reprogramming involvement in arthritis development. Distinct gene expression patterns were identified for different stages of disease, including downregulated expression of immunoglobulin heavy chain constant region genes and increased expression of inflammatory genes in the early phase, and downregulation of MHC class II genes in the late phase. The common changes occurred in both early and late phases included upregulation of Arl2bp and Mfap1, which are involved in the regulation of cytoskeletal dynamics.

Description
Super-selective intra-ophthalmic artery chemotherapy (SSIOAC) is an organ-specific drug-delivery strategy to treat retinoblastoma, the most common primary ocular malignancy in children. Unfortunately, recent clinical reports associate adverse vascular toxicities with SSIOAC using melphalan, the most commonly used chemotherapeutic. To explore the reason for the unexpected vascular toxicities, we have developed in vitro studies with human retinal endothelial cells to test the effects of the chemotherapeutics and a non-human primate model to monitor the SSIOAC treatment in real-time and post-treatment. Melphalan and carboplatin (another chemotherapeutic used to treat retinoblastoma via SSIOAC) triggered migration, proliferation, and apoptosis when used to treat human retinal endothelial cells. Melphalan was associated with increased adhesion of leukocytes to human retinal endothelial cells, and tended to increase with increased cell expression of adhesion proteins (ICAM-1) and soluble chemotactic factors (IL-8). Histopathology post-SSIOAC indicated vessel wall sloughing, leukostasis, and vessel occlusion. We have established an in vitro human cell culture model and a non-human primate model to evaluate strategies designed to obviate vascular side effects, and optimize the efficacy of SSIAOC and the drug preparations used in SSIOAC.
