claim: plasma proteomics reveals tissue-specific cell death and mediators of cell-cell interactions in severe covid-19 patients
evidence_1: by analyzing several thousand plasma proteins in 306 covid-19 patients and 78 symptomatic controls over serial timepoints using two complementary approaches, we uncover covid-19 host immune and non-immune proteins not previously linked to this disease.", "integration of plasma proteomics with nine published scrnaseq datasets shows that sars-cov-2 infection upregulates monocyte/macrophage, plasmablast, and t cell effector proteins.")
