The CAD phenotype was associated with transcriptional profiles of T lymphocytes (Tregs, T-CD4+, T-CD8+, and follicular T cells) and B lymphocytes (naive and memory cells), whereas the noCAD group was enriched with cell types associated with the innate immune system, such as granulocytes, monocytes, and mast cells. This evidence concerns the gene CD4 and coronary artery disorder.
