Wei Tao’s project explores the biological mechanisms to improve wound healing in adults by mimicking the scarless fetal wound healing process. This project aims to engineer a system that replicates the fetal extracellular matrix and immune responses, using mRNA techniques to produce specific proteins and inhibit biological processes leading to scar formation. This system employs lipid nanoparticles for mRNA delivery and hydrogel for controlled release, enabling spatiotemporal control of key components like collagen type III and interleukin-10, thereby reconstituting fetal-like extracellular matrix organization and modulating over-activated immune responses.

The project’s goals include establishing a foundation for future scarless wound healing studies, developing a hybrid mRNA therapeutic platform for skin defects and diseases, and correlating extracellular matrix and immune modulation with subsequent biological processes and outcomes. This research has promising potential for clinical applications in wound care and other dermatological diseases.

Brian Capell’s project seeks to better understand how epigenetic changes (modifications that do not change the sequence of genomic DNA) regulate the development of sebaceous glands.

Dysfunction of sebaceous glands (SGs) has been linked to a variety of common skin disorders ranging from atopic dermatitis to acne, sebaceous hyperplasia, seborrheic dermatitis and sebaceous tumors.

Brian Capell and his team have recently discovered that through genetic modification of the epigenome, they could promote a dramatic increase in the number and size of SGs (Ko, et al. Developmental Cell. In press. 2024). This surprising result demonstrated the direct role that epigenetics and chromatin organization plays in controlling SG development and abundance. It also suggested that targeting the epigenome might offer new ways to treat disorders characterized by aberrant SG development and activity.

Diseases related to aberrant SG development or activity can have a deleterious effect on both human physical and mental health. Despite this, very little is known of the role of epigenetics in SG development and homeostasis. To address this, Brian Capell’s project aims to test the influence of epigenomic modifiers and modifications upon SG development and disease to further dissect their contribution to the pathogenesis of these very common conditions.

Collectively, this project will address outstanding questions regarding the role of the epigenome in SG development and homeostasis and in common diseases driven by SG dysfunction – diseases that are both understudied and in need of better therapies.

The goal of Eliza Pei-Suen Tsou’s project is to understand the importance of aging endothelial cells (a cell type lining blood vessels) in scleroderma.

Scleroderma is an autoimmune disease characterized by inflammation, scarring of tissues and organs, including the skin, and changes in blood vessels throughout the body.

Most patients experience vascular abnormalities as one of the first symptoms, which trigger tissue stiffness and related complications later in the disease. Although these vascular changes are early critical events, the underlying cause of why they occur has not been determined.

Eliza Pei-Suen Tsou and her team found that dermal endothelial cells from scleroderma patients function differently compared to healthy controls. In particular, these cells undergo senescence, which is a process by which a cell ages but does not die off when it should. Over time, large numbers of senescent cells build up in the body. These cells remain active and release harmful substances that may cause inflammation and damage to nearby healthy cells.

In this project, Eliza and the team aim to determine the cause for vascular abnormalities in scleroderma, with a specific focus on how senescence is involved. They hypothesize that endothelial cell senescence is fundamental in causing the disease and might be targeted for therapy. Specifically, they propose that endothelial senescence accounts for the abnormality of endothelial cells in scleroderma, resulting not only in blood vessel changes but also in tissue scarring.

The goal is to determine why the endothelial cells acquire the senescent phenotype, and what this senescent phenotype does to promote the disease.

This project may form the basis for novel approaches to treating scleroderma.

Christopher Bunick’s project aims to improve and substantiate our current knowledge of the structure and function of Janus kinases (JAKs) to improve safety and efficacy when developing new JAK inhibitors.

Janus kinase (JAK) inhibitors are small molecule drugs that treat inflammatory dermatological conditions by inhibiting cytokine signaling. Currently targeted diseases include atopic dermatitis, psoriasis, hand eczema, alopecia areata, vitiligo, and hidradenitis suppurativa.

Optimal JAK inhibitor matching to dermatologic disease remains challenging because of cross reactivity among four related JAK kinases: JAK1, JAK2, JAK3 and TYK2. Each possesses catalytic kinase (JH1) and allosteric (JH2) domains (an allosteric domain is a site where binding of a molecule indirectly modulates the function of the protein, here the catalytic activity). Both JH1 and JH2 domains have been targeted for drug development, yet a scientific knowledge gap exists as to how the allosteric JH2 domain regulates catalytic JH1 function and the subsequent downstream activation of signal transducer and activator of transcription (STAT) proteins.

A barrier for JAK inhibitor prescription is its promiscuity; it may target more than one JAK, leading to broader cytokine suppression than desired. This poor selectivity is likely rooted in suboptimal drug discovery procedures emphasizing inhibitory capacity over selectivity, resulting in unexpected real-world side effects, including malignancy, cardiovascular events, and thrombosis.

Christopher Bunick and his team will use AI-based generative modeling, molecular dynamics, computational biophysics, structural biology, and biochemistry to (i) determine how JH2 allosterically regulates JH1; (ii) define the structural basis for enhancing selectivity against specific JAK domains; (iii) elucidate downstream mechanisms regulating STAT signaling; and (iv) elucidate molecular properties of JAKs beyond JH1/JH2 domains.

This project may pave the way for better and safer treatment of skin diseases using JAK inhibitors.

Julia Oh’s project aims to develop a novel and more physiological approach to studying how microbes interact with human skin cells and the effects of this interaction on overall skin health.

The human skin microbiome – encompassing hundreds of bacterial and fungal species – has essential roles in maintaining skin health. Skin microbiome dysfunction can contribute to diverse skin infections, inflammatory disorders, and skin cancer.

It is important to both identify the microbe–skin cell interactions that go awry in skin disease and to evaluate the therapeutic potential of new approaches for treating skin diseases. However, a detailed mechanistic understanding of how various skin microbes interact with human cells to maintain skin health or promote skin disease is currently lacking.

The goal of Julia Oh’s project is to determine how diverse skin microbes impact the essential functions of skin cells. However, there are few experimental models that allow us to investigate the diversity of skin microbes in a physiologically relevant way.

To enable a detailed investigation of microbe–skin cell interactions and their effects on skin health, Julia Oh and her team will model microbial colonization in cultured skin tissue that is genetically modified to investigate skin cell mechanisms. Then, using metabolomics and computational models, they will identify microbial metabolites to reveal microbial mechanisms.

This new approach could broadly enable biomedical researchers to determine how microbe–skin cell interactions impact skin functions, immunity, and susceptibility to diseases arising from microbial infection, and inform potential preventative and therapeutic strategies that harness the microbiome.

Valentina Greco’s project investigates the potential role of fibroblast and blood vessel maturation processes in systemic sclerosis (SSc) by monitoring development longitudinally in-vivo.

The skin protects organisms from their environment; it prevents water loss and infection and blocks physical insults. This barrier includes an outer layer and an inner, highly organized scaffold of fibers and blood vessels. Proper development of these two networks following birth is essential for health during adulthood; however, these processes are poorly understood.

Defects in the assembly and function of dermal fiber and blood vessel networks lead to severe diseases such as Systemic Sclerosis (SSc) or scleroderma. Identification of early SSc stages is crucial for the development of diagnostic, preventive, and therapeutic strategies. However, gaining this knowledge has been challenged by the inability to track these events longitudinally and in vivo.

Valentina Greco’s lab has overcome this roadblock and developed the ability for continuous visualization of skin networks, specifically how fibroblast and blood vessel networks develop after birth under healthy conditions. In this project – and building on this knowledge – they will utilize mouse models that mimic SSc in humans to investigate whether mechanisms crucial for postnatal skin maturation participate in this disease.

Valentina Greco’s project, if successful, will advance the understanding of the skin’s structural and blood vessel networks, shed light on their role in health and disease, and provide a solid foundation to improve clinical management of those suffering from often-lethal ailments such as scleroderma.

Cory Simpson’s project aims to investigate how mutations in the gene encoding the calcium pump SPCA1 cause the skin blistering disease Hailey-Hailey Disease (HHD) using human cellular and tissue models.

The epidermis forms the body’s outer armor from multiple layers of cells called keratinocytes, which assemble strong connections (desmosomes) to seal the skin tissue and prevent wounds. Several rare blistering disorders are linked to autoantibodies or gene mutations that disrupt desmosomes, causing keratinocyte splitting and skin breakdown. While autoimmune blistering diseases can be controlled by suppressing the immune system, treatments remain elusive for inherited blistering diseases.

One of these is Hailey-Hailey disease (HHD), which causes recurrent wounds, pain, and infections, leading to stigmatization of patients. Mutations in the ATP2C1 gene, which encodes the calcium pump SPCA1, were linked to HHD more than 20 years ago, yet the disease still lacks any approved therapies.

While it is known that SPCA1 resides in the Golgi apparatus (an organelle inside the cell responsible for protein processing and trafficking), our limited understanding of how SPCA1 deficiency compromises skin integrity has stalled drug development for HHD; moreover, mice engineered to lack SPCA1 did not replicate HHD.

Cory Simpson and his team at the University of Washington have built human cellular and tissue models of HHD to define what drives the disease and to discover new treatments. Their preliminary analysis of ATP2C1 mutant keratinocytes revealed impaired expression and trafficking of adhesive proteins, but also identified stress signals from mis-folded proteins and reactive oxygen species.

In this project, Cory Simpson and team will determine how these cellular dysfunctions compromise keratinocyte cohesion to cause skin blistering and test if cell stress pathways could serve as therapeutic targets for HHD.

Peggy Myung’s project aims to elucidate how two key molecular signals regulate the development of dermal condensate cells, a group of cells pivotal for hair formation.

The hair follicle dermal condensate (DC) is a cluster of quiescent dermal cells that can induce new hair follicle formation and holds the potential to revolutionize hair loss treatments. However, a key barrier to exploiting DCs to make new hair is that the molecular and cellular mechanisms that lead to DC formation are poorly understood.

Peggy Myung and her team recently identified two morphogen signals that are necessary and sufficient to drive DC formation. These two signals cooperate to unfold an initial stage of progenitor proliferation followed by a stage of cell cycle exit and DC maturation. Importantly, these stages of differentiation depend on levels of these two signals: Low levels induce progenitor proliferation; higher levels induce quiescence and DC maturation.

They hypothesize that different signaling levels regulate these stages of differentiation by inducing distinct signature genes that cause either DC progenitor expansion or terminal differentiation. They recently established a high-throughput dermal culture system to test this hypothesis. Using this novel platform and in vivo hair reconstitution assays, they aim to define how modulation of levels of these two signals regulates dermal gene expression profiles, cell cycle dynamics and DC function.

If successful, Peggy Myung’s project may define tunable molecular targets to develop novel treatments for hair loss and to make DC organoids for drug testing.
