View SamplesNeural precursor cells (NPCs) in the mammalian neocortex generate various neuronal and glial cell types in a developmental stage-dependent manner. Most neocortical NPCs lose their neurogenic potential after birth. We have previously shown that high mobility group A (HMGA) proteins confer the neurogenic potential on early-stage NPCs during the midgestation period, although the underlying mechanisms are not fully understood. Here we performed microarray analysis and compared expression profiles between control and HMGA2-overexpressed NPCs.

View SamplesThe significant changes of hematopoietic cells induced by Xbp1S expression indicate that there is global alteration in gene expression. UPR induces transcription of Xbp1, and phosphorylation of the ER transmembrane kinase IRE1 initiates UPR-mediated mRNA splicing of Xbp1, resulting in the production of Xbp1S, an active form of a basic leucine zipper transcription factor. In the present study, Xbp1S retrovirus vector infected 32cl3 cells show cell cycle arrest and myeloid differentiation. Xbp1S may modulate important genes of differentiation and the cell cycle.

View SamplesT cells that encounter cultured ocular pigment epithelial cells in vitro are inhibited from undergoing T cell receptor-triggered activation. Because retinal pigment epithelial (RPE) cells are able to suppress T-cell activation, we studied whether RPE cells could suppress cytokine production by activated T helper (Th) cells. In this study we showed that primary cultured RPE cells greatly suppressed activation of bystander CD4+ T cells in vitro, especially the cytokine production by the target T helper cells (Th1 cells, Th2 cells, Th17 cells, but not Th3 cells). Cultured RPE cells and RPE-supernatants significantly suppressed IL-17 producing CD4+ T cells, and RPE cells fully suppressed polarized Th17 cell lines that induced by recombinant proteins, IL-6 and TGFb2. Moreover, RPE cells failed to suppress IL-17 producing T cells in the presence of rIL-6. In addition, Th17 cells exposed to RPE were suppressed via TGFb, which produce RPE cells. These results indicate that retinal PE cells have immunosuppressive capacity in order to inhibit Th17-type effector T cells. Thus, ocular resident cells play a role in establishing immune regulation in the eye.

View SamplesPatients with combined heart and renal failure, also termed the cardiorenal syndrome (CRS), have high cardiovascular morbidity and mortality. Several key connectors between heart and kidney have been recognized, such as oxidative stress, inflammation, the renin-angiotensin system and the sympathetic nervous system. Monocytes are key players in the development of atherosclerosis and may act as a biosensor to detect changes in the systemic environment. Anemia, which occurs frequently in CRS, is partly due to an absolute and/or relative erythropoietin (EPO) deficiency. Until now, EPO treatment has largely been used to treat (renal) anemia, but recent research also showed beneficial non-hematopoietic effects such as anti-inflammatory and anti-oxidative capacities. The hypothesis of the present study was that monocyte gene expression profiles of cardiorenal patients compared to healthy controls reflect the systemic nature of CRS and are responsive to short-term treatment with Epo. The first aim was to investigate whether this short term treatment revealed non-hematopoietic EPO effects. The second aim was to address whether EPO dampens expression of genes involved in inflammation and oxidative stress. Given the variable response to EPO, the third aim was to test whether baseline gene expression profiles or the acute gene expression modulation by EPO are associated with EPO resistance.

View SamplesLung disease causes most of the morbidity and mortality in cystic fibrosis (CF). However, understanding its pathogenesis has been hindered by lack of an animal model with characteristic features of CF. To overcome this problem, we recently generated pigs with targeted CFTR genes. We now report that within months of birth, CF pigs spontaneously develop hallmark features of CF lung disease including airway inflammation, remodeling, mucus accumulation, and infection. Their lungs contained multiple bacterial species, suggesting an equal opportunity host defense defect. In humans, the temporal and/or causal relationships between inflammation and infection have remained uncertain. To investigate these processes, we studied newborn pigs. Their lungs showed no inflammation, but were less often sterile than controls. Moreover, after intrapulmonary bacterial challenge, CF pigs failed to eradicate bacteria as effectively as wild- type pigs. These results suggest that impaired bacterial elimination is the pathogenic event that initiates a cascade of inflammation and pathology in CF lungs. Finding that CF pigs have a bacterial host defense defect within hours of birth provides an exciting opportunity to further investigate pathogenesis and to test therapeutic and preventive strategies before secondary consequences develop.

View SamplesThroughout postnatal life in mammals, neural stem cells (NSCs) are located in the subventricular zone (SVZ) of the lateral ventricles. The greatest diversity of neuronal and glial lineages they generate occurs during early postnatal life in a region-specific manner. In order to evaluate potential heterogeneity in the NSC pool, we microdissected the dorsal and lateral SVZ at different postnatal ages and isolated NSCs and their immediate progeny based on their expression of Hes5-EGFP/Prominin1 and Ascl1-EGFP, respectively. Whole genome comparative transcriptome analysis revealed transcriptional regulators as major hallmarks that sustain postnatal SVZ regionalization. Manipulation of single genes encoding for locally enriched transcription factors influenced NSC specification indicating that the fate of regionalized postnatal SVZ NSCs can be readily modified . These findings reveal functional heterogeneity of NSCs in the postnatal SVZ and provide targets to recruit region-specific lineages in regenerative contexts.
