Serological studies have reported that patients with NPC generally exhibit high levels of IgA antibodies against EBV EA and VCA [15-21] and elevated titers of neutralizing antibodies against EBV DNA replication-related enzymes such as DNase, DNA polymerase and thymidine kinase also are detectable in the sera of patients with this disease [21-28]. Here, CD79A is linked to nasopharyngeal carcinoma.
