This research observed that EGFR activity appears to maintain hair follicle quiescence and immune privilege, and its inhibition may lead to stem cell apoptosis and scarring alopecia during inflammation.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study reported that in mouse models, deletion of EGFR resulted in stem cell hyper-proliferation followed by apoptosis, leading to scarring alopecia, and implicated EGFR's role in maintaining hair follicle quiescence and immune privilege during inflammation.
November 2022 in “Journal of Investigative Dermatology” This study implicates EGFR as a critical regulator of immune privilege and stem cell quiescence in hair follicles, suggesting a link between EGFR inhibition and inflammation-driven hair loss during cancer therapy.
February 2018 in “Trends in Immunology” This study demonstrated that antigens from the skin bacterium Staphylococcus epidermidis can stimulate CD8+ T cells, which in turn enhance wound healing.
January 2026 in “Inflammation and Regeneration” This review highlights that two-photon excitation microscopy is a valuable tool for visualizing live skin structures and immune responses at high resolution, though its clinical use is hindered by safety and cost issues.
