The selection of the proteins for the verification stage was based on the following criteria: (1) high fold change; (2) being representative of the 49 different proteins; (3) P value of <0.05 in KEGG analysis (XRCC4 and PCF11) or having biological functions associated with immunity and other infectious diseases (SEMA4A and ATP11A). Here, SEMA4A is linked to infectious disease.
