Adipose tissue iNKT cells have different functions than iNKT cells in the blood and other organs.
Regulatory iNKT cells lack expression of the transcription factor PLZF and control the homeostasis of T(reg) cells and macrophages in adipose tissue.

Plasmacytoid dendritic cells and C1q differentially regulate inflammatory gene induction by lupus immune complexes.
Specimen part, Treatment, Subject
View SamplesThe goal of this study was to determine what genes are up- and down-regulated in response to lupus immune complexes in purified CD14+ monocyte stimulations. Our results have shown that novel genes are induced by immune complexes but the response is less robust when using purified monocytes versus total PBMCs

View SamplesThese experiments were done to compare the gene expression profiles in CD4+ T cells responding to antigen presented by dendritic cells transiently or persistently. Some treatments include the activation of the dendritic cells by CD40 engagement.
Sustained antigen presentation can promote an immunogenic T cell response, like dendritic cell activation.

View SamplesThe aim of our study was to discover a miR marker panel prognostic of 5-year survival in OSCC patients that may be utilized in parallel with the current clinical covariates. We assessed differential expression of miRNAs genome-wide via deep sequencing in 20 tumor tissue samples. We also attempted to identify deregulated miR expression signatures that may serve as the prognostic marker of cancer survival. Selected miR marker-based panel then may serve as a guide for selection of appropriate follow-up chemo/radiation treatment, significantly improving the clinical management of OSCC and the overall survival rate. Overall design: Identify miRs differentially expressed in the poor prognosis group compared to the good prognosis group

View SamplesOvariectomized virgin Ccnd1-/- and Ccnd1+/+ mice (5 weeks of age) were allowed to recuperate for 2 weeks. The mice were assigned to either replacement pellets containing E2 (0.75 mg, 60-day release) or pellet containing placebo. Mice were sacrificed at day 7 after pellet implantation. RNA extracted from mammary glands (3 each group) was labeled and used to probe Affymetrix 430_2.0 arrays.

View SamplesThe CCND1 gene, which is frequently overexpressed in cancers, encodes the regulatory subunit of a holoenzyme that phosphorylates the retinoblastoma protein (pRb). It is known that cyclin D1 regulates ER transactivation using heterologous reporter systems, the significance of this observation to E2 dependent gene activation is unknow. E2 stimulated MCF7 cells treated with cyclin D1 siRNA in order to analyze the genes regulated by estradiol in a cyclin D1 dependent manner. Hormone deprived MCF7 cells were treated with cyclin D1 siRNA or control siRNA and stimulated with E2 or vehicle

View SamplesMurine prostate epithelial cells (PECs) were obtained from Ccnd1-/- and Ccnd1+/+ FvB mice (2-3 months of age). RNA extracted from PECs (3 technical replicates for each group) was labeled and used to probe Affymetrix 430_2.0 arrays.

View SamplesPrevious studies have suggested that CD133+ cells isolated from human kidney biopsies have the potential to ameliorate injury following intravenous (IV) administration in rodent models of kidney disease by integrating into damaged renal tissue and generating specialised renal cells. However, whether renal engraftment of CD133+ cells is prerequisite for ameliorating injury has not yet been unequivocally resolved. Here, we have established a cisplatin-induced nephropathy model in immunodeficient rats to assess the efficacy of CD133+ human kidney cells in restoring renal health, and to determine the fate of these cells after systemic administration. Specifically, following IV administration, we evaluated the impact of the CD133+ cells on renal function by undertaking longitudinal measurements of the glomerular filtration rate using a novel transcutaneous device. Furthermore, using histological assays, we assessed whether the human kidney cells could promote renal regeneration, and if this was related to their ability to integrate into the damaged kidneys. Our results show that both CD133+ and CD133- cells improve renal function and promote renal regeneration to a similar degree. However, this was not associated with engraftment of the cells into the kidneys. Instead, after IV administration, both cell types were exclusively located in the lungs, and had disappeared by 24 hours. Our data therefore indicate that renal repair is not mediated by CD133+ cells homing to the kidneys and generating specialised renal cells. Instead, renal repair is likely to be mediated by paracrine or endocrine factors.

View SamplesCD14+ human monocytes differentiating into DCs in the presence of IL4 and GM-CSF were treated with agonists for RXR and its partners or vehicle 18 hours after plating (experiment with RXR and permissive partners, donor 1-3) or 14 hours after plating (experiment with nonpermissive partners, donor 4-6). Cells were harvested 12 hours thereafter. Experiments were performed in biological triplicates representing samples from three different donors.
