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.
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.

September 2020 in “British journal of dermatology/British journal of dermatology, Supplement” This review explores the role of neutrophil recruitment in the inflammation seen in hidradenitis suppurativa and emphasizes potential therapeutic targets within these pathways, but it reports no new clinical results.
September 2023 in “Medicine” This study found increased infiltration of specific immune cells, such as γδ T cells and CD8+ T cells, in the bald scalp of male androgenetic alopecia patients, and identified four key immune-related genes potentially involved in hair loss development through interferon-γ signaling pathways.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that mitochondrial dysfunction might contribute to the pathogenesis of Lichen planopilaris by triggering a metabolic shift that leads to chronic inflammation and hair follicle damage.
