Mechanical tension worsens keloid scars by activating inflammation and fibrosis pathways.

This chapter reviews recent developments in vitiligo research, highlighting the role of melanocyte stem cell differentiation and oxidative stress in its management, but reports no new clinical results.

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.

This study conducted a scoping review and meta-analysis revealing a complex chemokine profile in alopecia areata patients, with elevated Th1, Th2, and other immune pathway chemokines, suggesting broader immunomodulatory strategies may help address the disease's multifaceted immune dysregulation.

In this scoping review and meta-analysis, researchers found that patients with alopecia areata exhibit complex chemokine profiles, with elevated levels of Th1, Th2, and other immune pathway-associated chemokines, suggesting the potential for broad immunomodulatory strategies to address the disease's immune dysregulation.

This study conducted a meta-analysis of gene expression data from alopecia areata patients, identifying 5109 differentially expressed genes and highlighting enriched pathways like JAK-STAT signaling, providing insights into the disease's pathogenesis and potential treatment targets.

This study explored COVID-related chilblains using transcriptomics and found they showed a distinct interferon and JAK/STAT pathway activation, absent in vaccine-related chilblains, with inflammatory cell types varying over time.

This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.

In this scoping review and meta-analysis, researchers found that patients with alopecia areata show a complex serum chemokine profile, predominantly involving Th1- and Th2-associated chemokines, suggesting that broader immunomodulatory strategies might address the diverse immune dysregulation observed in the disease.

In mouse models, this study showed that transplanted dermal papilla and dermal sheath cells can integrate into hair follicles, promoting hair growth and extended anagen phases, with their effectiveness influenced by factors such as immune response and cell passage number.

This study found that skin-infiltrating neutrophils play a crucial role in triggering chronic itch in atopic dermatitis by promoting skin hyperinnervation and enhanced expression of itch signaling molecules in a mouse model.
