PF4 and COVID-19: For proteins that were dysregulated only in moderate and/or under medication patients compared to healthy subjects, the Wiki-pathways found were the “network map of SARS-CoV-2 signaling pathways”, which include the upregulated proteins SERPINA10, LRG1, PF4, CPN1, APOC1, and the “RAS and bradykinin pathways in COVID-19”, which include the three upregulated proteins AGT, CPN1, PRKG1, and the “statin inhibition of cholesterol production” which also includes the upregulated proteins APOE, LCAT, and APOC1 (Figure 6).
