CD69 and Sepsis: Our results are consistent with Liao et al.’s findings (29), which suggested that the amount of CD69+ γδ T cells was larger in septic patients than that in healthy controls; and septic patients with poor outcomes had impaired CD69 expression level in γδ T cells after stimulation of pamidronate (29), indicating that CD69, as an early activation biomarker of T cells, could play a crucial role in the early of sepsis.
