June 2024 in “British Journal of Dermatology” This study found that treatment with EGFR inhibitors or mitogen-activated kinase inhibitors may compromise the immune privilege of human scalp hair follicles, suggesting new directions for managing drug-induced folliculitis.
July 2022 in “British Journal of Dermatology” This study found that epidermal growth factor receptor inhibitors used in cancer treatment induce a distinct inflammatory response in hair follicles, marked by immune privilege collapse and upregulation of inflammatory pathways.
July 2025 in “Journal of Investigative Dermatology” Alopecia areata involves complex immune cell interactions, especially between CD8+ T cells and macrophages, which could help develop new treatments.
This study found that UV radiation-induced fibroblast depletion in the skin is primarily due to a deregulated inflammatory response, with T cells aiding fibroblast survival under stress.
