The result demonstrated that SERPINA1 expression presented strong connections to B cells in 25 cancer types, CD4+ T cells in 28 cancer types, CD8+ T cells in 25 cancer types, neutrophils in 32 cancer types, macrophages in 31 cancer types, and dendritic cells (DCs) in 32 cancer types (Figure 8A). The gene discussed is CD8A; the disease is cancer.
