Project description:In the present study, RNA-seq were performed To explore biological significance of IL-27 and BST2 in the neuro-cutaneous signaling network of chronic itch. mRNA profiles were generated by deep sequencing, in triplicate, using MGISEQ-2000. We found that both human keratinocytes and murine sensory neurons responded to IL-27 and BST2, resulting in enrichment of genes promoting itch and inflammation. IL-27-BST2 signaling pathway activation promotes cutaneous inflammation and itch, both leading into an aggravation of AD. This finding might help us to better understand the immune-neuro-modulatory mechanism in itch circuits

Project description:We found that the E3 ubiquitin ligase Itch significantly affects early B-cell differentiation. To explore the role of Itch in late B-cell differentiation, we sorted B cells from WT and Itch KO mice. To explore the effect of Itch deficency on gene expression, we determined mRNA profiles in B cells from WT and Itch KO mice by RNA-seq. RNA-seq was done with an Illumina HiSeq 2500 instrument at GENEWIZ, Suzhou, China.

Project description:To test the hypothesis that defects in the termination of inflammatory signaling led to skin inflammation that results in the “Itchy” phenotype, we isolated RNA from the lesional skin of Itch-/- mice and from the skin of wild-type mice and performed genome-wide mRNA expression profiling by RNA sequencing. We ranked genes based on the fold change in their expression (increased or decreased) in Itch-/- skin relative to that in wild-type skin. The expression of several TNF–induced genes were increased in Itch-/- skin, including, IL-1?, IL-6, IL-11, IL-19, IL-1RL1, CCL4, CXCL3, CXCL2, CCL3, and CD14. mRNA profiles comparison between wild type (WT) skin and Itch-/- mice lesional skin

Project description:In the present study, RNA-seq were performed To identify clinical relevance of PLAUR, a putative Serpin E1 receptor, in cutaneous itch signaling and crosstalk pathways with other critical itch modulators.mRNA profiles were generated by deep sequencing, in triplicate, using MGISEQ-2000. Our experiment showed Serpin E1-treatment further led to a marked upregulation of TLR2 transcript in mDRG neurons, along with enhanced transcription of cosignaling proteins belonging to pro-inflammatory signaling pathways including NF-κB signaling proteins. We next investigated the consequence of TLR2 activation in mTGNs using the TLR agonists, Pam3CSK4 (TLR1/2 agonist), FSL-1 (TLR2/6 agonist), or vehicle. Among these transcripts, TLR2 was found upregulated strongest by both TLR2 agonists suggesting a selfenhancing feedback loop of TLR2 activation.The PLAUR-TLR2 axis promotes cutaneous inflammation and itch, both feeding into an aggravation of AD. This finding might help us to better understand the skin-nerve communication in itch circuits.

Project description:The E3 ubiquitin ligase Itch regulates antibody levels and prevents autoimmune disease in humans and mice, yet how Itch regulates B cell fate or function is unknown. We now show that Itch directly limits B cell activity. Using LC-MSMS, we profiled and compared the whole cell proteomes of Itch deficient and Itch sufficient CpG-stimulated B cells. B cells lacking Itch exhibited increased levels of mTORC1 targets and E2F transcription factor targets. These results support a novel role for Itch in limiting B cell metabolism and proliferation.

Project description:Itch is an unpleasant skin sensation which can be triggered by exposure to many chemicals including those released by mast cells. The Nppb-expressing class of sensory neurons when activated elicit scratching responses in mice, however, it is unclear which itch-inducing agents stimulate these cells and the receptors involved. Here, we identify receptors expressed by Nppb-neurons and demonstrate the functional importance of these receptors as sensors of endogenous pruritogens released by mast cells. Our search for receptors in Nppb-neurons revealed that they express leukotriene, serotonin, and sphingosine-1-phosphate receptors. Targeted cell ablation, calcium imaging of primary sensory neurons, and conditional receptor knockout studies demonstrate that these receptors induce itch by the direct stimulation of Nppb-neurons and neurotransmission through the canonical GRP-dependent spinal cord itch pathway. Together our results define a molecular and cellular pathway for mast cell-induced itch.

Project description:The dorsal root ganglion (DRG) neurons take in charge of primary detection and transmission of peripheral pain and itch stimuli, however, as two distinct noxious sensation, it is still attractive for this field that how the DRG neurons differentially response and code pain and itch. Here, we investigate the response and activation spectrum of DRG neurons under peripheral pain and itch stimuli using in vivo two-photon calcium imaging, and find differences in the responsive intensity to pain and itch between multisensory neurons (both pain and itch) and single-sensory neurons (either pain or itch). Besides, single-cell RNA sequencing (scRNA-seq) is used to reveal the heterogeneity of distinct subpopulations based on their expression of pain- or itch-related marker genes and indicates the similarity and difference of their transcriptomic changes under chronic pain and itch. Our results will provide fundamental insights to the peripheral pain and itch differential coding mechanism, moreover, benefit the development of pain and itch therapies.

Project description:To mount an anti-pathogen response, CD4 T cells must undergo rapid cell proliferation. However, poorly controlled expansion can result in diseases such as autoimmunity. One important regulator of T cell activity is the E3 ubiquitin ligase Itch. Itch deficient patients suffer from extensive autoinflammation. Similarly, Itch deficient mice exhibit inflammation characterized by high numbers of activated CD4 T cells. While the role of Itch in limiting CD4 T cell cytokine production has been extensively studied, it is less clear whether and how Itch regulates proliferation of these cells. We determined that Itch deficient CD4 T cells are hyperproliferative in vitro and in vivo, due to increased S phase entry. Whole cell proteomics analysis of Itch deficient primary mouse CD4 T cells revealed increased abundance of the -catenin co-activator WW domain binding protein 2 (WBP2). Furthermore, Itch deficient cells demonstrate increased WBP2 protein stability, and Itch and WBP2 interact in CD4 T cells. Knockdown of WBP2 in CD4 T cells caused reduced proliferation. Together, our data support that Itch attenuates CD4 T cell proliferation by promoting WBP2 degradation. This study identifies novel roles for Itch and WBP2 in regulating CD4 T cell proliferation, providing insight into how Itch may prevent inflammation.
