FIGURE 2.

Western blot of exosome proteins from LTxRs with known SARS‐CoV‐2 (LTxRs‐COVID‐19; n = 7) for MST1, AGTR1, GRA‐B, and coronavirus proteins (229E). C is the control and 1–7 are exosome samples from each patient. (B) Densitometry and statistical analysis of exosomes from control and LTxRs‐COVID‐19, which was positive for SARS‐CoV‐2 spike protein S2, MST1, AGTR1, GRA‐B, lung SAgs (Col‐V, Kα1T), and NFkB proteins. (C) Western blot of exosome proteins from control and from asymptomatic LTx candidates (Asx; n = 7) for MST1, AGTR1, GRA‐B, coronavirus protein (229E), lung SAgs (Col‐V, Kα1T), and NFkB. (D) Densitometry and statistical analysis from control and Asx plasma positive for the SARS‐CoV‐2 spike protein S2, MST1, AGTR1, GRA‐B, coronavirus protein (229E), lung SAgs (Col‐V, Kα1T), and NFkB proteins. *All statistical analyses were performed using Mann–Whitney test using GraphPad Prism version 8.0
