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. ​.
