Gene expression profiling of sensitive skin

ABSTRACT: Sensitive skin is a hyperactive skin condtion, characterized by prickling, burning, itching, stinging, pain, or tingling sensation, which develops in response to various internal and external stimulants that can be tolerated by most people. The pathophysiology involved in the development of sensitive skin remains largely elusive. To characterize differential gene expression profiles in sensitive skin, we investigated the genome-wide patterns of gene expression from skin samples from subjects with sensitive or non-sensitive skin, following lactic acid challenge or normal saline application using cDNA microarrays.

Gene expression profiling of sensitive skin

Project description:Sensitive skin is a hyperactive skin condtion, characterized by prickling, burning, itching, stinging, pain, or tingling sensation, which develops in response to various internal and external stimulants that can be tolerated by most people. The pathophysiology involved in the development of sensitive skin remains largely elusive. To characterize differential gene expression profiles in sensitive skin, we investigated the genome-wide patterns of gene expression from skin samples from subjects with sensitive or non-sensitive skin, following lactic acid challenge or normal saline application using cDNA microarrays. We recruited eighteen healthy volunteers with sensitive skin (n=9) or non-sensitive skin (n=9). From each subject, two skin samples were obtained following lactic acid or normal saline application.(18 samples/group) Based on the existence of sensitive skin and lactic acid challenge, samples were pooled into sets of three individuals each. Global transcriptome profiling was conducted using Affymetrix Human Genome U133 Plus 2.0 array.

Whole genome transcriptional profiling of reconstructed human epidermis treated with 5% lactic acid compare to negative control as treated with water

Project description:Lactic acid is used to check skin sensitivity of human. However transcriptional profiling has not been done yet. This study was targeted to understand the transcriptional changes occur in human skin upon treatment with lactic acid.

Quantitative characterization of the neuropeptide level changes in dorsal horn and dorsal root ganglia regions of the murine itch models

Project description:In this study, we performed a label-free relative quantitation to identify the peptide candidates correlated with itch sensation in murine models. We tested two different itch models-the AEW model (known commonly as the dry skin model) and the MC903 model. Performed peptide extraction from the dorsal horn (DH) and dorsal root ganglia regions of these two models and compared their levels with that of control mice.

Immune checkpoint blockade unleashes aberrant immune responses against the microbiota

Project description:Immune checkpoint inhibitors (ICIs) targeting PD-1 and CTLA-4 are essential components of the cancer therapeutic armamentarium. The remarkable responses seen with ICIs however, are also accompanied by immune-related adverse events (irAEs). These inflammatory side-effects impact virtually all organ systems, with the most common being the skin and gastrointestinal tract. Here, we establish a mouse model of commensal bacteria-driven skin irAEs and demonstrate that immune checkpoint blockade aberrantly unleashes commensal-specific T cell responses. Such responses caused widespread immune cell infiltration and inflammation throughout the skin, recapitulating the skin irAEs seen in patients treated with ICIs. This skin inflammation was dependent on production of the cytokine IL-17 by commensal-specific T cells, which in turn induced hyperactive responses from macrophages and myeloid cells. Importantly, these responses had long-term consequences, with commensal-specific T cells elicited in the context of ICIs being highly sensitive to re-activation by commensals months later. Together, our results establish a mouse model of skin irAEs and show that immune checkpoint blockade can potentiate aberrant immunity to skin commensals with long-lasting consequences.

RNAseq profiling of neonatal mouse Merkel cells and basal keratinocytes

Project description:Merkel cells (MCs), specialized neuroendocrine touch sensors within the epidermis, play a crucial role in tactile sensation. To gain deeper insignts into their molecular characteristics, we employed RNA sequencing (RNA-seq) to explore the transcriptome of MCs in comparsion to basal keratinocytes in neonatal mouse skin.

RNA-seq of mouse tissue samples from animal model：Effects of MMP9 on gene expression.

Project description:In the present study, RNA-seq technique were performed To explore biological significance of MMP9 in the neuro-cutaneous signaling network of chronic itch. We used MMP-9-IN-1, a specific inhibitor of MMP9, or its vehicle to treat ACD model mice, and conducted high-throughput sequencing on ear tissue samples of mice. It was found that inhibition of MMP9 expression affected the expression of a variety of itching factors and skin inflammatory factors related to the skin pathology of chronic dermatitis. These changes may indicate that MMP9 is closely related to inflammation and pruritus. This finding might help us to better understand the immune-neuro-modulatory mechanism in itch circuits.

Metabolic Reprogramming and Reliance in Human Skin Wound Healing

Project description:Impaired skin wound healing is a significant global health issue, especially among the elderly. Wound healing is a well-orchestrated process involving the sequential phases of inflammation, proliferation, and tissue remodeling. Although wound healing is a highly dynamic and energy-requiring process, the role of metabolism remains largely unexplored. By combining transcriptomics and metabolomics of human skin biopsy samples, we mapped the core bioenergetic and metabolic changes in normal acute as well as chronic wounds in elderly subjects. We found upregulation of glycolysis, the tricarboxylic acid cycle, glutaminolysis, and β-oxidation in the later stages of acute wound healing and in chronic wounds. To ascertain the role of these metabolic pathways on wound healing, we targeted each pathway in a wound healing assay as well as in a human skin explant model using metabolic inhibitors and stimulants. Enhancement or inhibition of glycolysis and, to a lesser extent, glutaminolysis had a far greater impact on wound healing than similar manipulations of oxidative phosphorylation and fatty acid β-oxidation. These findings increase the understanding of wound metabolism and identify glycolysis and glutaminolysis as potential targets for therapeutic intervention.

Lung cell responses to wood combustion aerosols

Project description:Human A549 lung epithelial cells were exposed directly at the air-liquid interphase towards combustion aerosols of wood burning. The goal was to compare the responses towards different wood and burning conditions. Beech log woods were burnt in a modern masonry heater, soft wood pellets were burnt in a pellet boiler.
