The CD3+CD4a–CD8a+CD8b+gating consistently provided lower cell numbers than the CD3+CD4a–CD8a+gating [50–70%, e.g., 69% (34%, 63%) in sepsis baseline, 62% (36%, 66%) in 18 h sepsis vs. 48% (36%, 64%) in sepsis+MSC baseline, 60% (42%, 63%) in 18 h sepsis+MSC] suggesting a significant population of TCR γδ cells. This evidence concerns the gene CD8B and Sepsis.
