Description
T 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.

Description
Retinoid X receptor (RXR)-gamma is a nuclear receptor-type transcription factor expressed mostly in the skeletal muscle, and regulated by nutritional conditions. Previously, we established transgenic mice overexpressing RXR-gamma in the skeletal muscle (RXR-gamma mice), which showed lower blood glucose than the control mice. We used microarrays to investigate their glucose metabolism gene expression change.

Description
Adult (6- to 8-week-old) C57BL/6 purchased from CLEA Japan Inc. (Tokyo, Japan) were used as donors ocular pigment epithelium (PE). To cultivate retinal PE (RPE) eyes were cut into two parts along a circumferential line posterior to the ciliary process, creating a ciliary body-deficient posterior eyecup. The eyecup was then incubated in 0.2% trypsin (Biowhitaker) for 1 hr. These tissues were triturated to make a single cell suspension, and then re-suspended in the medium.

Description
The 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.

Description
Ethanol inhibits the proliferation of neural stem cells in the fetal, adolescent, and adult brain. The consequences are cognitive deficits associated with fetal alcohol spectrum disorder and alcohol use disorder. We tested the hypothesis that ethanol affects progression through cell cycle checkpoints by differentially modifying transcriptional processes. Monolayer cultures of NS-5 neural stem cells were treated for 48 hr with the mitogenic agent FGF2 or the anti-mitogenic TGF1 in the absence or presence of ethanol. Cell cycle elongation was induced by a global down-regulation of genes involved in cell cycle progression, including the cyclin E system. Checkpoint regulation occurred downstream of p21 and Jun-oncogene signaling cascades. Thus, ethanol can affect cell cycle progression by altering transcript expression of strategic genes downstream of the G1/S checkpoint.

Description
The Ag receptors on alpha/beta and gamma/delta T cells differ not only in the nature of the ligands that they recognize but also in their signaling potential. We hypothesized that the differences in alpha/beta - and gamma/delta TCR signal transduction were due to differences in the intracellular signaling pathways coupled to these two TCRs. To investigate this, we employed transcriptional profiling to identify genes encoding signaling molecules that are differentially expressed in mature alpha/beta and gamma/delta T cell populations. Unexpectedly, we found that B lymphoid kinase (Blk), a Src family kinase expressed primarily in B cells, is expressed in gamma/delta T cells but not in alpha/beta T cells. Analysis of Blk-deficient mice revealed that Blk is required for the development of IL-17-producing gamma/delta T cells. Furthermore, Blk is expressed in lymphoid precursors and, in this capacity, plays a role in regulating thymus cellularity during ontogeny.

To understand the molecular mechanisms mediating Liver Resident Leukocytes (LRL) relocalization from the liver to the lungs in response to tumor progression, isolated LRLs from the liver and lungs of tumor-stimulating mice using a cell sorter. LRLs remaining in the liver displayed increased liver signature when compared to those that migrated into the lungs.
