Hypercholesterolemai is a major contributor to atherosclerosis development. To assess the effects of hypercholesterolemia on the transcriptional profiling in foam cells, mice were fed regular chow, or WD for 2 or 14 weeks prior to sacrifice.

View SamplesGroup-2 innate lymphoid cells (ILC2) serve crucial function in allergy and asthma. Activated ILC2 rapidly proliferate and secret large amounts of type-2 cytokines, such as IL-5 and IL-13. Mechanisms underlying still remain ambiguous. Here we report that Myc is required for ILC2 proliferation and activation in allergic airway inflammation. Inhibition of Myc impair the ILC2 proliferation in vivo and prevented ILC2-mediated airway hyperresponsiveness in vivo.

View SamplesA common method used both in vitro and in vivo, to identify Tregs in CD4+ T cells is through the characterization of surface marker CD25. Although CD25 expression is well correlated with regulatory activity in vitro, CD4+CD25+ T cells are not the only regulatory CD4+ T cells in vivo. Studies suggest that in many situations, CD4+CD25 T cells are as effective as CD4+CD25+ T cells in controlling T cell mediated disease. Therefore, CD25 is not a uniquely specific cell surface marker for the identification of Tregs. CD49f is an 6-integrin subunit which dimerizes with either the 1 or 4 subunit to form receptors for various laminin isoforms. We found that CD4+ T cells from NOD mice express CD49f, and old non-diabetic NOD mice had an increase of CD4+CD49f+ T cells in the spleen and peripheral lymph node when compared to both young and diabetic mice.

View SamplesThe goal of this study was to identify genes that are differentially expressed after genetic deletion of both alleles of the Cyp26a1 gene in murine embryonic stem cells. Cyp26a1 codes for the CYP26A1 enzyme which metabolizes RA to polar RA metabolites, such as 4-oxo-RA and 4-OH-RA. CYP26A1-/- ES cells do not metabolize RA within 48 hours of RA treatment while in Wt ES cells, polar RA metabolites are already detectable by 8 hr. In addition, the absence of CYP26A1 enzyme increases intracellular RA levels. By gene microarray analysis, we wanted to identify genes that would be affected by the lack of the Cyp26a1 gene.
CYP26A1 knockout embryonic stem cells exhibit reduced differentiation and growth arrest in response to retinoic acid.

View SamplesCD8+ NKT cells are naturally occurring but rare T cells that express both T cell and natural killer (NK) cell markers. These cells may play key roles in establishing tolerance to self antigens; however, the mechanism of action and the molecular profiles of these cells are poorly characterized due to their extremely low frequencies. We developed a highly efficient in vitro conversion/expansion protocol for such cells and extensively characterized their functional and molecular phenotypes using a variety of genomic and immunological techniques.

View SamplesThis study was undertaken in order to characterize the functions of Rex-1 and identify potential Rex-1 target genes.Both alleles of the Rex-1 gene were disrupted in J1 mouse embryonic stem cells. Gene expression levels in one of the resulting Rex-1 knockout cell lines was compared to that of J1 wild type cells.
