The researchers reported that several m6A-related genes, particularly IGF2BP3, were differentially expressed in keloid tissue compared to normal skin, indicating potential targets for understanding keloid pathogenesis and treatment.

This study found that in mice with alopecia areata, CD8+ T cells showed clonal expansion and specific regulatory networks, which might help identify new therapeutic targets for patients not responding to JAK inhibitors.

This review examines how mathematical modeling of the MAPK pathway, enhanced by single-cell proteomic data, improves understanding of regulatory mechanisms, predicts system behavior, and guides experimental research, emphasizing recent developments in modeling and inference.

In this study, fibroblasts treated with the small molecule peficitinib were reprogrammed into dermal papilla cell-like cells capable of inducing hair growth, offering a new strategy for hair loss treatment.

This study found that specific gene upregulations and mutations in hidradenitis suppurativa skin support the role of inflammation, altered epithelial differentiation, and metabolism dysregulation in the disease's pathogenesis.

This study observed that nevus melanocytes do not exhibit signs of senescence, suggesting that their growth arrest is due to cell interactions and not directly caused by BRAF activation.

In this study, researchers used transcriptomics and modeling to uncover previously unknown cell populations and marker genes in developing hair follicles, providing insights into early cell fate establishment and offering tools for further research on skin appendages.

This study used a probabilistic Boolean network model to explore hair follicle cell fate regulation and predicted that varying TGF-β levels, in coordination with BMP and TNF, can influence either apoptosis or cell proliferation during different follicle growth stages.

This article reviews skin regeneration and fibrosis, identifying key cellular and molecular players, and emphasizing the potential to manipulate the postwound environment to promote regeneration over fibrosis.

This study re-analyzed single-cell RNAseq data from human and mouse skin, confirming and refining insights into keratin gene regulation during keratinocyte differentiation in epithelial tissues.

This research re-analyzed single-cell gene expression data from a mouse model, confirming that certain genes involved in the EDA-EDAR and WNT pathways are crucial for skin appendage development, suggesting that their restoration may mitigate the effects of hypohidrotic ectodermal dysplasia in children.

This review discusses the complex genetic factors contributing to androgenetic alopecia, highlighting the variability in genetic risk across different populations and the emerging understanding of personalized treatment strategies, but reports no new clinical findings.

The researchers in this study identified a new subpopulation of dermal fibroblasts in neonatal murine dermis marked by EGFR, which they report contributes to hair follicle regeneration through the promotion of IGF1, potentially aiding in wound-induced hair follicle neogenesis.

This study found that Krox20 marks a diverse stem cell population in mouse hair follicles, which significantly contributes to the interfollicular epidermis and regulates epidermal homeostasis.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This study examined noninvasive tissue samples, including buccal swabs, hair follicles, saliva, and urine cell pellets, and found hair follicles and urine cell pellets promising for transcriptomic and clinical analyses due to their sample quality and performance in disease-relevant applications.

In this clinical trial, patients with lichen planopilaris treated with the oral TYK2 inhibitor deucravacitinib showed significant improvement in PGA, LPPAI, and Skindex-16 scores over 24 weeks, with transcriptomic analyses indicating decreased inflammatory and immune pathway activity post-treatment.
