These findings indicated that the functions of EBV activated B lymphocytes of NPC patients and high titer of IgA/VCA individuals were lower than low titer of IgA/VCA and negative individuals in early immunological response of EBV infected PBMC.

• 结果表明；在EBV体外感染PBMC所引起的早期免疫反应中；NPC患体者和IgA/VCA高滴度者EBV活化的B细胞功能较IgA/VCA低滴度和阴性者降低.
