    TLDR Immune activities and specific genes are important in male pattern baldness.
    This study used bioinformatics to analyze scalp biopsies from 14 male AGA patients and healthy controls, identifying 234 differentially expressed genes (DEGs) enriched in extracellular matrix and immune-related pathways. Key genes such as SERPINA1, POMC, and THBS1 were highlighted, along with significant differences in immune cell composition, particularly CD4 T cells, macrophages, and mast cells. These findings suggest that immune-related activities and specific hub genes play crucial roles in AGA's development, offering potential diagnostic biomarkers and therapeutic targets, though further validation with larger cohorts is needed.
