CD14 and atrial fibrillation: The data described above demonstrated a predominant increased CD14+HLA-DR–/low cells in the accompanying ascites in comparison with the PB of OC patients; as previous studies have shown the presence of multiple inflammatory cytokines in the AF from OC patients and several inflammatory cytokines have been defined to be able to promote the expansion and accumulation of MDSC, we examined the levels of multiple inflammatory cytokines in the paired PB sera and AF from OC patients by cytokine array and then determined whether their levels were associated with the abundance of CD14+HLA-DR–/low MDSC.
