In vivo gene signature of TLR3KO mice stimulated by ethanol (EtOH) or all trans retinoic acid (atRA) treatment

ABSTRACT: How developmental programs reactivate in regeneration is a fundamental question in biology. We addressed this question through the study of Wound Induced Hair follicle Neogenesis (WIHN), an adult organogenesis model where stem cells regenerate entirely new hair follicles de novo following deep wounding. The exact mechanism is uncertain. Here we show that self-noncoding dsRNA activates the anti-viral receptor TLR3 to induce intrinsic retinoic acid (RA) synthesis in a gradient that predicts new hair follicle formation after wounding in mice. Additionally, in humans, rejuvenation lasers induce gene expression signatures for dsRNA and RA, with measurable increases in intrinsic RA synthesis. These results demonstrate a novel stimulus for retinoic acid synthesis by non-coding dsRNA, relevant to their broad functions in development and immunity. The goal of this experiment is to investigate the profile of gene expression rescued by atRA in TLR3KO mice.

Noncoding dsRNA induces retinoic acid synthesis to stimulate hair follicle regeneration via TLR3

Project description:This SuperSeries is composed of the SubSeries listed below. How developmental programs reactivate in regeneration is a fundamental question in biology. We addressed this question through the study of Wound Induced Hair follicle Neogenesis (WIHN), an adult organogenesis model where stem cells regenerate de novo hair follicles following deep wounding. The exact mechanism is uncertain. Here we show that self-noncoding dsRNA activates the anti-viral receptor toll like receptor 3 (TLR3) to induce intrinsic retinoic acid (RA) synthesis in a pattern that predicts new hair follicle formation after wounding in mice. Additionally, in humans, rejuvenation lasers induce gene expression signatures for dsRNA and RA, with measurable increases in intrinsic RA synthesis. These results demonstrate a potent stimulus for RA synthesis by non-coding dsRNA, relevant to their broad functions in development and immunity.

In vivo gene signature of human skin with CO2 laser treatment

The goal of this study is to investigate whole genome analysis in human skin with CO2 laser treatment, which leads to enhanced skin rejuvenation. Under Hopkins IRB (IRB00028768), 17 Caucasian women Fitzpatrick types I-III with average age of 55 and moderate to severe baseline photoaging were enrolled. Laser treatments and biopsy schedule were as listed, with treatments occurring both to the arm, and arm biopsies used for gene expression data listed.

Retinoic acid promotes tissue regeneration by resolving stem cell lineage plasticity

Project description:Stem cells upended from their niche upon injury display lineage plasticity, a transient multi-lineage state essential for tissue repair. Employing high-throughput approaches and three-dimensional cultures of hair follicle stem cells (HFSCs), we investigate the signals that govern the transition between homeostatic regeneration and lineage plasticity. We identify retinoic acid (RA) as a master orchestrator of HFSC behavior during these two processes. In the hair follicle, RA signals within defined niches and interacts with WNT and BMP cues to drive hair regeneration. In wounded skin, reduced RA signaling prompts HFSCs to prioritize epidermal re-epithelialization and must be restored to promote hair regrowth. Substantiated in vivo, our findings have profound therapeutic implications for hair growth and for chronic wounds and cancers, where lineage plasticity is unresolved.

Functional stem cell aging dictated by skin tissue microenvironment

Project description:Organismal aging in mammals is manifested with architectural alteration and functional decline of multiple organs throughout the body. In aged skin, hairs are sparse, which has led to the hypothesis that the hair follicle stem cells (HFSCs) undergo epidermal differentiation during aging. Here, we employ single cell analysis to interrogate aging-related changes in the HFSCs. Unexpectedly, HFSCs maintain their lineage fidelity and show no signs of shifting to an epidermal fate. Despite maintaining lineage identity, HFSCs do show prevalent transcriptional changes in extracellular matrix genes. Of importance, these HFSC changes are accompanied by profound architectural perturbations in the aging stem cell niche. Upon surveying the dermis from young and aged skin, we also observe age-related changes in many non-epithelial cell types, including resident immune cells, sensory neurons, arrector pili muscles, and blood vessels – all of which have been previously associated with abilities to modulate hair follicle regeneration. Consistent with both intrinsic and extrinsic alterations in stem cell: niche communications, we find that in response to skin wounding, aged HFSCs repair the epidermis, but are defective in hair follicle regeneration. Intriguingly, whereas aged dermis cannot support young HFSCs, aged HFSCs can be rescued when supported by young dermis. Together, these findings favor a model where skin tissue microenvironment plays a dominant role in dictating the molecular properties and activities of HFSCs.

JAK-STAT1 as therapeutic target for EGFR deficiency-associated inflammation and scarring alopecia (scRNA-seq)

Project description:The hair follicle stem cell niche is an immune-privileged microenvironment, characterized by reduced antigen presentation, thus shielding against permanent immune-mediated tissue damage. In this study, we demonstrated the protective role of hair follicle-specific epidermal growth factor receptor (EGFR) against scarring hair follicle destruction. Mechanistically, disruption of EGFR signalling generated a cell-intrinsic hypersensitivity within the JAK-STAT1 pathway, which, synergistically with interferon gamma expressing CD8 T-cell and NK-cell-mediated inflammation, compromised the stem cell niche. Hair follicle-specific genetic depletion of either JAK1/2 or STAT1 or therapeutic inhibition of JAK1/2 ameliorated the inflammation, restored skin barrier function and activated the residual stem cells to resume hair growth in mouse models of epidermal and hair follicle-specific EGFR deletion. Skin biopsies from EGFR inhibitor-treated and cicatricial alopecia patients indicated active STAT1 signalling and interferon target expression. Notably, a case study of folliculitis decalvans, characterized by progressive hair loss, scaling and perifollicular erythema, demonstrated successful treatment with JAK1/2 inhibition. Our findings offer molecular insights and present a mechanism-based therapeutic strategy for addressing chronic folliculitis associated with EGFR-inhibitor anti-cancer therapy and cicatricial alopecia.

Project description:Wound Induced Hair Follicle neogenesis (WIHN) is a hair neogenesis phenomenon which occurred in the center of scar. Neonatal hair follicle are separated from the preexisting follicles by a hairless circular. We analysed the differentially expressed proteins between inner and outer area of scar at post-wound day 15 by iTRAQ technology.
