Moreover, recent reports linked plasma proteomic changes of COVID-19 patients to different degrees of disease severity, with special emphasis on tissue repair and coagulation proteins, such as the SERPINAs, inflammatory markers and regulators, like CRP and TSKU, macrophage trafficking markers, like SELENOP, as well as immune cell markers such as LBP and CD14 [68–75]. This evidence concerns the gene TSKU and COVID-19.
