View SamplesThe object of the study is to examine the role of the neuropeptide Y (NPY) and its receptor (NPY1R) on pulmonary phagocytes in the pathology of influenza virus infection. Wild type and phagocyte-specific NRY1R knockout mice were non-infected or infected with influenza virus, and mRNA-seq analyses were performed using pulmonary phagocytes isolated from those mice.

View SamplesT-follicular helper cells (Tfh) differentiate through a multistep process culminating in germinal center (GC) resident GC-Tfh that provide support to GC B-cells. T-follicular regulatory cells (Tfr) have been shown to have critical roles in the control of Tfh and germinal center formation. While Tfh cells are inhibited by IL-2, Treg cells depend on it. Here we describe a novel CD25 negative subset within both murine and human PD1+CXCR5+Foxp3+ Tfr that is preferentially located in the GC and can be clearly differentiated from non-GC Tfr, Tfh and effector Tregs by expression of a wide range of molecules. In comparison to Tfr and effector Tregs, GC-Tfr cells partially downregulate IL-2 dependent canonical Treg features, but retain suppressive function, while simultaneously upregulating genes associated with Tfh and GC-Tfh. We suggest that, similar to Tfh, Tfr follow a differentiation pathway culminating in a distinct GC resident subset, GC-Tfr.

View SamplesThe B1 SOX transcription factors SOX1/2/3/19 have been implicated in various processes of early embryogenesis. However, their regulatory functions in stages from the blastula to early neurula remain largely unknown, primarily because loss-of-function studies have not been informative to date. In our present study, we systematically knocked down the B1 sox genes in zebrafish. Only the quadruple knockdown of the four B1 sox genes sox2/3/19a/19b, which are active in the early embryo, resulted in very severe developmental abnormalities, confirming that the B1 sox genes are functionally redundant. We characterized the sox2/3/19a/19b quadruple knockdown embryos in detail by examining the changes in gene expression through microarray analysis as well as in situ hybridization.

View SamplesWe identified RNA targets of Matrin3 using SH-SY5Y by PAR-CLIP analysis. Because Matrin3 mainly bound to intron of pre-mRNA, in order to find the effect of Matrin3 on splicing pattern and expression, we knocked down Matrin3 using SH-SY5Y cells by electroporation and extracted total RNAs from those cells. The total RNAs were subjected to whole transcripts microarray GeneChip Affymetrix Human Transcriptome array 2.0.
Matrin3 binds directly to intronic pyrimidine-rich sequences and controls alternative splicing.

View SamplesWe previously isolated a subclone, MIN6 clone 4, from the parental MIN6 cells, that shows well-regulated insulin secretion in response to glucose, glybenclamide, and KCl, even after prolonged culture. To investigate the molecular mechanisms responsible for preserving GSIS in this subclone, we compared four groups of MIN6 cells: Pr-LP (parental MIN6, low passage number), Pr-HP (parental MIN6, high passage number), C4-LP (MIN6 clone 4, low passage number), and C4-HP (MIN6 clone 4, high passage number). Based on their capacity for GSIS, we designated the Pr-LP, C4-LP, and C4-HP cells as responder cells. In a DNA microarray analysis, we identified a group of genes with high expression in responder cells (responder genes), but extremely low expression in the Pr-HP cells.

View SamplesAnalysis of Foxp3(+)epigenetics(-) T cells, Foxp3(-)epigenetics(+) T cells, and Foxp3(+)epigenetics(+) T cells. Results indicate regulatory T cell (Treg) ontogenesis requires two independent processes, expression of the transcription factor Foxp3 and establishment of Treg epigenetic programs induced by T cell receptor (TCR) stimulation.
T cell receptor stimulation-induced epigenetic changes and Foxp3 expression are independent and complementary events required for Treg cell development.
