(Submitter supplied) During acute cutaneous inflammation in diseases such as atopic eczema there are alterations in the microbiome as well as histological and ultrastructural changes to the stratified epidermis, but the precise interaction between the keratinocyte proliferation and differentiation status and the skin microbiome has not been fully explored. We hypothesised that the skin microbiome contributes to regulation of keratinocyte differentiation and can modify antimicrobial responses. more...

(Submitter supplied) Skin colonisation of varied communities of commensal microorganisms, such as Staphylococcus aureus (SA), Staphylococcus epidermidis (SE) and Staphylococcus capitis (SC) form the microbiome; a necessity for healthy skin. The skin changes characteristic of atopic dermatitis, a common inflammatory skin disease, have been shown to provide a favourable niche for SA colonisation. We utilised a reconstructed human epidermal (RHE) model recapitulating the stratified anatomy of the epidermis on which to test host responses to bacterial colonisation. more...

(Submitter supplied) The skin epidermis provides a vital barrier for preventing transepidermal water loss (TEWL) and environmental stimuli. However, the molecular mechanisms ensuring barrier integrity remain not fully understood. RORα is a nuclear receptor highly expressed in the epidermis of normal skin. However, its epidermal expression is significantly reduced in the lesions of multiple inflammatory skin diseases. In this study, using mice with epidermis-specific Rora gene deletion (RoraEKO), we have demonstrated the central roles of RORα in stabilizing skin barrier function. more...

(Submitter supplied) This study investigates the role of ADAM17 (a disintegrin and metalloproteinase 17) in skin homeostasis. Here, we show that mice lacking ADAM17 in keratinocytes have a normal epidermal barrier and skin architecture at birth, but develop pronounced defects in epidermal barrier integrity soon after birth and chronic dermatitis as adults. The dysregulated expression of epidermal differentiation proteins becomes evident 2 days after birth, followed by transepidermal water loss and inflammatory immune cell infiltration. more...

(Submitter supplied) Palmoplantar skin is structurally and functionally unique, but the transcriptional programs driving this specialization are unknown. Here, we exploit single-cell RNA-sequencing of human palm, sole, and hip skin to describe the distinguishing characteristics of palmoplantar and non-palmoplantar skin while also uncovering previously unappreciated differences between palmar and plantar sites. Our approach reveals downregulation of diverse immunological processes and decreased immune cell populations in palmoplantar skin, highlighting an altered immune environment in the skin of the palms and soles. more...

(Submitter supplied) Palmoplantar skin is structurally and functionally unique, but the transcriptional programs driving this specialization are unknown. Here, we exploit bulk and single-cell RNA-sequencing of human palm, sole, and hip skin to describe the distinguishing characteristics of palmoplantar and non-palmoplantar skin while also uncovering previously unappreciated differences between palmar and plantar sites. Our approach reveals downregulation of diverse immunological processes and decreased immune cell populations in palmoplantar skin, highlighting an altered immune environment in the skin of the palms and soles. Further, we identify specific palmoplantar and non-palmoplantar fibroblast populations that appear to orchestrate key differences in cell-cell communication in palm, sole, and hip. Dedicated analysis of epidermal keratinocytes highlights major differences in basal cell fraction among the three sites and validates the presence of a more differentiated, cycling basal population. Finally, our data demonstrate the existence of two spinous keratinocyte populations that constitute two parallel, site-selective epidermal differentiation trajectories. Together, these results provide a deep characterization of the highly adapted palmoplantar skin and contribute new insights into the fundamental biology of human skin.

(Submitter supplied) Several methods for generating human-skin-equivalent (HSE) organoid cultures are in use to study skin biology; however, few studies thoroughly characterize these systems. To fill this gap, we use single-cell transcriptomics to compare in vitro HSEs, xenograft HSEs, and in vivo epidermis. By combining differential gene expression, pseudotime analyses, and spatial localization, we reconstruct HSE keratinocyte differentiation trajectories that recapitulate known in vivo epidermal differentiation pathways and show that HSEs contain major in vivo cellular states. more...

(Submitter supplied) The endocannabinoid (eCB) system plays an active role in epidermal homeostasis. Phytocannabinoids such as CBD modulate this system but also act through eCB-independent mechanisms. This study evaluated effects of CBD, bakuchiol (BAK) and ethyl (linoleate/oleate) (ELN) in keratinocytes (KCs) and reconstituted human epidermis (RHE). Molecular docking simulations showed that each compound binds the active site of the eCB carrier fatty-acid-binding protein 5 (FABP5). more...
