This study found that C57BL/6 mice and Sprague–Dawley rats show distinct distributions of eccrine sweat glands and hair follicles in their volar skin, suggesting these models should be selected according to research focus on skin appendages.

This study evaluated treatments for frontal fibrosing alopecia and found hydroxychloroquine and 5a-reductase inhibitors to be most effective, with 70-72% of patients experiencing stabilization or improvement, but limitations in treatment consistency and assessment methods remain.

In this study, researchers found that pigs with genetically disrupted ANTXR1 were resistant to Senecavirus A infection, showing no clinical symptoms, and provided a model for human GAPO syndrome, while confirming ANTXR1 as a receptor for the virus.

Finasteride helps treat frontal fibrosing alopecia, improving or stabilizing the condition in many patients.

This study found that intermediate filaments and matrix proteins in presumptive hair shaft cells are synthesized sequentially, identifying a new polypeptide component that changes during hair cell differentiation.
