Although the available evidence favors the presence of severe immunopathology during COVID-19 ARDS, the compartmental transmission of immunoinflammatory processes between blood and lungs remains unexplored, and characterization of distinct leukocyte subpopulations and their cytokine mediators could thus potentially reveal both novel therapeutic targets and guide the timing of treatment. In the present study, we immunophenotyped bronchoalveolar lavage fluid (BALF) and blood of mechanically ventilated patients with moderate-to-severe COVID-19 ARDS. [33] [34] [35] A recent study performed genome-wide transcriptome sequencing of RNA obtained from BALF in 3 patients with COVID-19 with unknown disease severity; it reported different expression of 1004 genes, including a high expression of cytokines such as MCP-1, IP-10, MIP-1A, and MIP-1B. In conclusion, our study provides novel phenotypic insight into the cell composition and inflammatory mediators simultaneously present in the lungs and blood in patients with COVID-19 ARDS. ./cache/cord-302886-5zjghwkq.txt ./txt/cord-302886-5zjghwkq.txt
