Thus, we sorted the iNKT, Treg, CD4 +T, and CD8+ T cells from the peripheral blood mononuclear cells (PBMCs)of 10 healthy volunteers, 10 patients with allergic asthma, and 10 patients with nonallergic asthma and examined their mRNA expression of ACC1 and PPARG. This evidence concerns the gene CD4 and asthma.
