Circulating Th1 and Th2 Subset Accumulation Kinetics in Septic Patients with Distinct Infection Sites: Pulmonary versus Nonpulmonary by Ming Xue, Yuying Tang, Xu Liu, Mingyuan Gu, Jianfeng Xie, Ling Liu, Yingzi Huang, Fengmei Guo, Yi Yang, Haibo Qiu

“…Persistent peripheral CD4+T cell differentiation towards T helper (Th)2 rather than Th1 has been proved to be related to immunosuppression and poor prognosis in sepsis. However, it is unclear whether these circulating Th1 and Th2 subtype accumulations differed in septic populations of distinct infection sites and presented different associations with outcomes among patients with pulmonary versus nonpulmonary sepsis. …”
