CD8A and autoimmune hepatitis: Quantitative profiling of the 22 immune cell subtypes revealed significant compositional shifts in AIH specimens relative to controls (Fig. 5D, E), with B-lymphocyte populations demonstrating marked enrichment in AIH microenvironments (Fig. 5F, Table S17), while xCell immunoinfiltration analysis showed significant enrichment of CD8 + T cells with iDCs in the AIH group (Fig. S27, Table S19).
