In OCI-Ly3 (ABC-origin DLBCL) cells, nuclear translocation of CagA, nuclear p-CagA expression, and nuclear localization of NFATc1 were simultaneously observed 1 and 6 h after HP (HM#2) infection, whereas cytoplasmic p-NFATc1 expression decreased at 1 and 6 h after HP (HM#2) infection (Fig. 1C). Here, CD8B is linked to infection.
