IgG and IgA antibody responses to some proteins from human cytomegalovirus (HCMV), influenza A virus (H1N1 and H3N2), hepatitis B virus (HBV), vaccinia virus (VACV), and varicella-zoster virus (VZV) were detected in many pooled serum samples in both NPC and control groups (Fig. 2A), which suggests these proteins are highly immunogenic. Here, CD79A is linked to nasopharyngeal carcinoma.
