The results indicated significantly lower proportions of immune-associated cells in CAD samples, including endothelial cells (p = 0.0411), macrophages (p = 0.0152), NK (natural killer) cells (p = 0.0113), smooth muscle cells (p = 0.0326), Tgd (T gamma delta) cells (p = 0.0242), Th1 cells (p = 0.0233), Th2 cells (p = 0.0335), and CD8 Tem (effector memory T cell, p = 0.0263) (Figure 5a). The gene discussed is ABCA1; the disease is coronary artery disorder.
