November 2025 in “The Journal of Immunology” This study found that CD80 expression in wound-activated hair follicle stem cells induces Foxp3 expression in effector T cells, facilitating wound repair by converting them into regulatory T cells.
October 2025 in “Science Advances” In this study, researchers demonstrated that CD4 T cells from skin-draining lymph nodes in mice with alopecia areata can transfer the disease to recipient mice, revealing a critical role for CD4 T cells in disease development and suggesting potential therapeutic targets.
In this study, researchers found that CD4 T cells from the skin draining lymph nodes of mice with alopecia areata can transfer the disease to recipient mice, highlighting the key role of these cells and their interaction with CD8 T cells in the disease's development.
