April 2023 in “Journal of Investigative Dermatology” This study identified TGFβ-2 as a potential driver of progenitor cell loss in hair follicles from early androgenetic alopecia scalps, suggesting its role in the condition's molecular disturbances.
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.
June 2023 in “Research Square (Research Square)” In this study, researchers used spatial transcriptome profiling to identify immune disturbances in the peri-infundibular region of androgenetic alopecia patients’ hair follicles, finding increased CD4+ T cells with a bias toward Th2 immune responses compared to controls.
November 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.
