January 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.
December 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.
October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.
October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.
August 2023 in “Journal of Knowledge Learning and Science Technology ISSN 2959-6386 (online)” This review discusses the use of single-cell RNA sequencing and spatial transcriptomics to enhance understanding of the pathogenesis and targeted therapies for chronic inflammatory skin conditions, highlighting technology advancements and the need for cost reduction and standardization.
June 2022 in “bioRxiv (Cold Spring Harbor Laboratory)” This study provides evidence that innate lymphoid cells-type 1 can induce alopecia areata in human hair follicles, challenging the view that it is solely a CD8+ T cell-driven autoimmune disease.
April 2026 in “Journal of Pharmaceutical Investigation” This review discusses recent advancements in nanotechnology for treating hypertrophic scarring and atopic dermatitis, highlighting the potential of nanotherapeutic platforms in enhancing therapeutic effects by modulating the skin's microenvironment.
In this study, researchers used a mouse model to identify an adipocyte-to-fibroblast conversion pathway that promotes mast-cell recruitment and dermal fibrosis in atopic dermatitis, suggesting a potential therapeutic approach to block this process and reduce inflammation and fibrosis.
December 2025 in “Nature Communications” In this study using mouse models, researchers found that elevated IL-17a in aged olfactory epithelium impairs olfactory function, while IL-17a inhibition promotes regeneration and mitigates age-related decline.
October 2020 in “Veterinary Dermatology” This review discusses autoimmune blistering diseases across species and highlights new treatment efficacy findings and ongoing trials, but it reports no new clinical results.
January 2014 in “Durham e-Theses (Durham University)” In this study, the activation of Notch1 signaling in keratinocytes was found to play a key role in recruiting immune cells and facilitating skin repair after injury.
October 2013 in “Journal of Investigative Dermatology” Collagen VII helps skin heal and stay strong, sirolimus may lower skin cancer risk in kidney transplant patients, high-molecular-mass hyaluronan helps naked mole rats resist cancer, dermal γδ T cells aid in hair growth in rodents, and overexpression of IL-33 in mouse skin causes itchiness, offering a model for studying allergic inflammation treatments.
