Prenatal alcohol exposure alters steady-state and activated gene expression in the adult rat brain
  • organism-icon Rattus norvegicus
  • sample-icon 192 Downloadable Samples
  • Technology Badge IconIllumina ratRef-12 v1.0 expression beadchip

Description

Background: Prenatal alcohol exposure (PAE) is associated with alterations in numerous physiological systems, including the stress and immune systems. We have previously shown that PAE increases the course and severity of arthritis in an adjuvant-induced arthritis (AA) model. While the molecular mechanisms underlying these effects are not fully known, changes in neural gene expression are emerging as important factors in the etiology of PAE effects. As the prefrontal cortex (PFC) and hippocampus (HPC) play key roles in neuroimmune function, PAE-induced alterations to their transcriptome may underlie abnormal steady-state functions and responses to immune challenge. The current study examined brains from adult PAE and control females from our recent AA study to determine whether PAE causes long-term alterations in gene expression and whether these mediate the altered severity and course of arthritis in PAE females Methods: Adult females from PAE, pair-fed [PF], and ad libitum-fed control [C]) groups were injected with either saline or complete Freunds adjuvant. Animals were terminated at the peak of inflammation or during resolution (days 16 and 39 post-injection, respectively); cohorts of saline-injected PAE, PF and C females were terminated in parallel. Gene expression was analyzed in the PFC and HPC using whole genome mRNA expression microarrays. Results: Significant changes in gene expression in both the PFC and HPC were found in PAE compared to controls in response to ethanol exposure alone (saline-injected females), including genes involved in neurodevelopment, apoptosis, and energy metabolism. Moreover, in response to inflammation (adjuvant-injected females), PAE animals showed unique expression patterns, while failing to exhibit the activation of genes and regulators involved in the immune response observed in control and pair-fed animals. Conclusions: These results support the hypothesis that PAE affects neuroimmune function at the level of gene expression, demonstrating long-term effects of PAE on the CNS response under steady-state conditions and following an inflammatory insult. Key words: prenatal alcohol exposure (PAE), ethanol, inflammation, arthritis, gene expression, rat.

Transcription profiling of hMC cells treated with PDGF (10ng/ml) LXA4 (1nM) for a 24h period
  • organism-icon Homo sapiens
  • sample-icon 8 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133A Array (hgu133a)

Description

Previous data have demonstrated the attenuation of platelet-derived growth factor (PDGF)-induced hyperproliferation and migration in primary human mesangial cells by lipoxin A4. In these experiments we aimed to find out what the effect of Lipoxin A4 would be on the global genomic changes associated with PDGF. We treated cells with PDGF (10ng/ml) ± LXA4 (1nM) for a 24h period and examined genomic differences, we could derive from our results that lipoxin A4 was diminishing the pro-inflammatory, pro-proliferative and pro-fibrotic responses induced by PDGF.

  • Technology Badge Icon Affymetrix Human Gene 1.0 ST Array (hugene10st)

Description

Gene expression profiles in this submission were part of an integrative DNA methylation and gene expression integrative study. The goal of this study was to determine whether DNA methylation patterns were disrupted in small airway epithelia of patients with Chronic Obstructive Pulmonary Disease (COPD) compared to airways from subjects with normal lung function. No subject has cancer or asthma at time of collection. Corresponding DNA methylation profiles for these subjects can be found at GSE55454.

Expression data from naive, effector and memory-like ILC2s isolated from mouse lungs and those from effector and memory-like ILC2s isolated from mediastinal lymph node
  • organism-icon Mus musculus
  • sample-icon 16 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 2.0 ST Array (mogene20st)

Description

Group 2 innate lymphoid cells (ILC2s) in the lung are stimulated by inhaled allergens. ILC2s do not directly recognize allergens but they are stimulated by cytokines including interleukin (IL)-33 released by damaged epithelium.Lung ILC2s, upon stimulation, produce T helper 2 cell-type cytokines inducing T cell independent allergic lung inflammation. We now report that lung ILC2s, upon activation by an allergen or IL-33, acquire the properties of memory cells. The activated ILC2s initially proliferate and secrete cytokines, followed by a contraction phase as they stop producing cytokines. Nevertheless, some persist long after the resolution of the inflammation and acquire intrinsic capacities to react to unrelated allergens more vigorously than nave ILC2s, thus mediating a severe allergic lung inflammation. Gene expression profiles of the previously activated ILC2s show a gene signature of memory T cells. These antigen non-specific memory ILC2s may explain why asthma patients are often sensitized to multiple allergens.

Differences in the transcriptomic response of human adult and neonatal dendritic cell subsets to TLR7/8 stimulation
  • organism-icon Homo sapiens
  • sample-icon 72 Downloadable Samples
  • Technology Badge IconIllumina human-6 v2.0 expression beadchip

Description

Previous studies have shown that purified dendritic cells (DCs) have cell-intrinsic, age-dependent differences in their response to TLR stimulation. To delineate which aspects of the age-dependent difference in innate immunity are cell intrinsic vs extrinsic, we searched for global differences to TLR7/8 stimulation in purified adult vs neonatal DC populations. We hypothesize that very few selected cell intrinsic differences in gene expression of key immune genes between these 2 age groups exist, and the bulk would be cell extrinsic differences. The results show that there are age-dependent differences in expression of several key genes involved in the immune response at baseline already. Upon stimulation, we identified a substantially larger fraction of age-dependent differentially expressed genes in conventional than plasmacytoid DCs. Bioinformatics analyses indicate that important immune pathways were significantly differentially expressed in DC subsets between the 2 age groups.
