The proportion of porcine immune cells isolated from PBMCs changed with age. A Stacked histogram of eight distinct immune cell proportions in 15 PBMC samples. B Line chart of cell proportions of CD4αβ T cells, CD4 helper T cells, CD8 T cells, gamma delta T cells, naïve B cells and NK cells changing with age. C Distribution of ATAC peaks within ± 10 kb of core gene transcriptional start sites (TSS) in up clusters and down clusters. D Box plot of the proportion of naive B cells in PBMC of Landrace pigs and Songliao Black pigs. E GO enrichment analysis of DEGs in PBMC of Landrace pigs and Songliao Black pigs. 1M: 1-month-old, 4M: 4-month-old, 7M: 7-month-old
