Despite high levels of CXCR3 ligands in mechanically ventilated COVID-19 patients, BALF CD8 T cells were not enriched in CXCR3 cells but rather CCR6 , likely due to high CCL20 levels in BALF, and had very high PD-1 expression. In mechanically ventilated, but not ward, patients Th-1 immunity is impaired. .
尽管机械通气的 COVID-19 患者的 CXCR3 配体水平较高,但 BALF CD8 T 细胞并未富集 CXCR3 细胞,而是 CCR6,这可能是由于 BALF 中 CCL20 水平较高,并且 PD-1 表达水平非常高。在机械通气的患者中,但不在病房患者中,Th-1 免疫受损。
