July 2026 in “The Journal of Immunology” This study observed that in both mouse and human models of alopecia areata, T cells exhibit a stress response involving heat shock proteins and other regulatory markers, suggesting their potential as targets for therapeutic intervention in this autoimmune skin disease.
This study provides a detailed analysis of cell subpopulations in a mouse model of wound-induced hair follicle regeneration, revealing specific cellular dynamics and heterogeneity that may influence hair follicle neogenesis.
February 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that tissue damage in adult mice triggers the release of mitochondrial DNA, which activates the TLR9 pathway and influences hair regeneration by recruiting gamma delta T cells, ultimately affecting healing outcomes such as fibrosis.
March 2023 in “Research Square (Research Square)” In this study, researchers found that changes in immune cell infiltration and immune-related gene expression may contribute to the immune microenvironment changes in male androgenetic alopecia.
This study found that interleukin-1α and interleukin-7 secreted by keratinocytes enhance the proliferation of γδT-cells and epidermal stem cells, revealing mechanisms of stem cell activation during wound healing in mice.
