The role of aquaporin-3 (AQP3) in functions of alveolar macrophage (AM) during ovalbumin (OVA)-induced asthma

Project description:We compared the gene expression profiles of AMs using microarray analysis between AMs from wild-type (WT) and AQP3-deficient (AQP3-/-) mice before and after OVA challenge RNA was extracted from AMs of WT and AQP3-/- mice before and after OVA challenge. We prepared 4-6 mice for each group and pooled their samples.

Expression data from ovalbumin (OVA) induced asthma model

Project description:MiRNAs are involved in the pathogenesis of bronchial asthma and are involved in the regulation of airway inflammation, airway remodeling and airway hyperreactivity. In this experiment, we constructed OVA asthma model and identified the differentially expressed miRNAs in asthma and normal models by microarray technology, providing a preliminary basis for future studies on the mechanism of asthma. We used microarrays to detail the global program of gene expression in asthma models and identify miRNAs that are differentially expressed in this process.

Mouse model of severe asthma: ovalbumin challenge

Project description:Mouse lung samples from mice challenged with OVA or PBS control. Wildtype (B6) mice were tested, as well as mast cell deficient mice with engraftment of normal mast cells and mast cells deficient in IgE or Ifn-gamma signaling.

Profiling whole lung from Ovalbumin (OVA)-challenged and control BALB/c mice

Project description:This program aims at identifying the lung gene signature associated with OVA-challenged mouse asthma model to facilitate understanding of the disease mechanism and therapeutic compound testing The OVA-challenged profiling data was analyzed by identifying genes that were up- and down-regulated at selected p value and fold change in the lungs of OVA-challenged mice compared to the corresponding PBS-treated controls.

In vivo polarization of Ovalbumin (OVA)-specific CD4 (OTII) T cells

Project description:There remains a need for analysis of CD4 helper T cells differentiation in vivo. To this end ovalbumin (OVA)-specific CD4 (OTII) T cells transferred into congenic mice were studied. Live attenuated OVA-expressing Salmonella (SalOVA) induce T-bet and IFN-g in OTII cells, while alum-precipitated OVA (alumOVA) induces GATA-3 and IL-4. Although 70% of alumOVA-responding OTII cells express GATA-3, only 7% produce IL-4. Thus Th2-polarization defined solely by IL-4 production does not recognize the diversity of GATA-3-expressing effectors. Low-density arrays were designed to assess the expression of 384 genes by real-time RT-PCR. Extensive early diversification occurred in both responses. SalOVA selectively induced many chemokines and pro-inflammatory cytokines, while alumOVA induced few Th2-associated cytokines. Several cytokines and molecules associated with Th17 cells and follicular helper cells were also induced by both antigens. The transcription factor Helios was exclusively induced in alumOVA-responding OTII cells, and critically not in standard in vitro Th2-polarization systems. Early synchronous up-regulation of Helios and GATA-3 mRNA is paralleled at protein level with largely coincident localization in specific nuclear foci of OTII cells responding to alumOVA. This appears to be consistent with a key role for both transcription regulators in the direction of Th2 responses in vivo. Keywords: In vivo T cell polarization Ovalbumin (OVA)-specific CD4 (OTII) T cells were transferred into C57BL/6 mice that were immunized either with live attenuated OVA-expressing Salmonella (Sal) or with alum-precipitated OVA (alum), or not (Naïve). Gene expression assay was performed on FACS sorted OTII cells (Naïve, Sal, Alum). OTII cells were purified from three independent groups of ten naïve, or SalOVA-immunized or alumOVA-immunized mice.

Effects of OVA challenge in mouse model of asthma

Project description:Challenge with ovalbumin antigen is a common model for asthma in mice. We sought to identify the gene expression differences in lung tissue in naïve and OVA-sensitized mice, in response to OVA challenge.

The Serpin-like Loop-insertion of Ovalbumin Increases Stability and Reduces OVA 323-339 Epitope Immunogenicity

Project description:Chicken ovalbumin (cOVA) has been studied for decades primarily due to the robust genetic and molecular resources that are available for experimental investigations. cOVA is a member of the serpin superfamily of proteins that function as protease inhibitors, although cOVA does not exhibit this activity. As a serpin, cOVA possesses a protease-sensitive reactive-center loop that lies adjacent to the OVA 323-339 CD4+ T-cell epitope. We took advantage of the previously described single-substitution-variant, OVA R339T, which can undergo the dramatic structural transition observed in serpins to study how changes in loop size and protein stability influences CD4+ T-cell priming in vivo. We observed that the OVA R339T loop-insertion increases stability and protease resistance, resulting in reduced CD4+ T-cell priming of the OVA 323-339 epitope in SJL mice. These findings have implications for the design of more effective vaccines for the treatment of infectious diseases and cancer as well as the development of more robust CD4+ T-cell-epitope prediction tools.
