The researchers reported that in patients with contact dermatitis, certain immune and skin barrier biomarkers, such as Th-cell mediated markers and cholesterol derivatives, may help distinguish between irritant and allergic subtypes, suggesting potential for improved diagnosis through integrated analysis.

This study found that pro-inflammatory cytokines and apoptotic mechanisms, specifically involving granzyme B and Fas pathways, are associated with chronic alopecia areata, indicating their potential role in the disease's persistence.

This review highlights that T cells are crucial in regulating hair follicle regeneration and their disruption can lead to alopecia, providing insights into hair disorders related to T cell immune balance and hair follicle regeneration.

This review discusses immune pathways involved in alopecia areata and explores emerging, more targeted therapeutic strategies, noting their potential for better safety and effectiveness compared to traditional immune suppressants.

This manuscript reviews the latest understanding of alopecia areata's pathogenesis, highlighting the roles of genetic, immunological, and environmental factors, with a focus on immune responses involving IFN-γ and cytotoxic CD8+ T-cells as key contributors to hair follicle inflammation and function disruption without follicle destruction.
