Alopecia areata is complex, with genetic and immune factors, and animal models are key for future treatment research.

This study suggests that distinct chromatin topologies allow different lineage-specific enhancers to regulate Hoxd genes in mouse vibrissae and chicken feather primordia, while conserved regulatory elements maintain transcriptional robustness in the embryonic trunk across species.

This review discusses spatial and temporal patterns in animals, focusing on skin appendage organs, but provides no new research findings.

This study found that nanoparticles did not permeate intact rat skin but could penetrate skin that had been artificially punctured, primarily through grooves or hair follicles.

This study found that MYC and FGF pathways are crucial for hair cell regeneration in chick and zebrafish models, suggesting potential targets for promoting hair cell regeneration in mammals.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

Herman Bierens had a successful career in econometrics, contributed to education, and plans to continue research after retirement.

This study indicates that reduced activity of the matriptase-prostasin proteolytic cascade is likely the cause of human autosomal recessive ichthyosis with hypotrichosis, as demonstrated using a novel mouse model.

This review discusses the roles of Wnt signaling in skin organogenesis and related processes but reports no new experimental results, highlighting areas for future research.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.

In this study using zebrafish, four bisbenzylisoquinoline derivatives were found to protect hair cells from aminoglycoside-induced damage without reducing antibiotic efficacy, potentially leading to therapies for patients undergoing such treatments.

This study revealed that differential gene and protein expression in the "Yufen I" H line chicken breed is crucial for Columbian plumage coloration, particularly in the melanogenesis pathway.
