Many symptoms associated with allergic asthma result from the sequelae of type 2 inflammation. Interleukin (IL)-25 promotes type 2 inflammatory responses, and T2M cells represent an IL-4 and IL-13 producing granulocytic IL-25 responsive population.
Interleukin-25 induces type 2 cytokine production in a steroid-resistant interleukin-17RB+ myeloid population that exacerbates asthmatic pathology.

View SamplesWe sought to determine the impact of chorioamnionitis exposure on term neonatal monocyte transcription. RNA-seq was performed on term healthy and chorioamnionitis-exposed umbilical cord blood purified CD14+ monocytes under unstimulated and LPS stimulated conditions. Overall design: RNA-seq on 11 samples with 2-3 replicates per exposure/stimulation group (each replicate contains 3 pooled samples)
Chorioamnionitis exposure remodels the unique histone modification landscape of neonatal monocytes and alters the expression of immune pathway genes.

View SamplesTo investigate whether FRCs express molecules capable of promoting the functions of activated T cells, we expanded FRCs from primary lymph node stromal cell (LNSC) cultures as previously described (Lukacs-Kornek et al., Nature Immunology, 2011), and then cultured them alone or with splenocytes activated with soluble antibody (0.25μg/ml) against CD3 (anti-CD3) and anti-CD28 for 16 hours. FRCs co-cultured with activated T cells upregulated expression of genes encoding molecules known to dampen T cell function such as Arg1, CD274 and Nos2. However, in response to activated T cells, FRCs also upregulated molecules with immunostimulatory capabilities such as Icosl, Cd40 and Il6.

View SamplesTo characterize underlying changes in the retinal pigment epithelium (RPE)/choroid with age, we produced gene expression profiles for the RPE/choroid and compared the transcriptional profiles of the RPE/choroid from young and old mice. The changes in the aged RPE/choroid suggest that the tissue has become immunologically active. Such phenotypic changes in the normal aged RPE/choroid may provide a background for the development of age-related macular degeneration.

View SamplesWe used optic nerve injury as a model to study early signaling events in the neuronal soma following axonal injury. Optic nerve injury results in the selective death of retinal ganglion cells (RGCs). The time course of cell death takes place over a period of days with the earliest detection of RGC death at about 48 hr post injury. We hypothesized that in the period immediately following axonal injury, there are changes in the soma that signal surrounding glia and neurons and that start programmed cell death. In the current study, we investigated early changes in cellular signaling and gene expression that occur within the first 6 hrs post optic nerve injury. We detected differences in phosphoproteins and gene expression within this time period that we used to interpret temporal events. Our studies revealed that the entire retina has been signaled by the RGC soma within 30 min after optic nerve injury and that pathways that modulate cell death are likely to be active in RGCs within 6 hrs following axonal injury

View SamplesmRNA expression in the spinal cords of the G93A-SOD1 familial ALS transgenic mouse model was compared to that in nontransgenic (Normal mouse) and transgenic mice expressing wild-type (WT)SOD1. Gene Ontology (GO)analysis was used to characterize differences in expression between G93A-SOD1 mouse and nontransgenic mouse spinal cord. Changes in multiple GO categories were found. Many of these were associated with subsystems involving cell-cell communication and intracellular signal transduction. Expression profiles of mice expressing WT-SOD1 did not differ from nontransgenic mice. In contrast, protein profiling using proteomics technology indicated changes in mitochondrial protein expression in the G93A-SOD1 mouse spinal cord that were not found in the mRNA expression analysis.
