Abstract |
Rituximab is a chimeric monoclonal antibody directed against the CD20 antigen. Treatment using rituximab in combination with chemotherapy has dramatically improved overall survival rate of diffuse large B cell lymphoma (DLBCL). Since rituximab can deplete both lymphoma B cells and normal B cells, how rituximab-treatment affects normal B cell function in DLBCL patients under remission is unclear. Here, we examined peripheral blood B cell composition and antigen-specific B cell responses in DLBCL patients in remission and observed reductions in the frequencies of total B cell as well as several major B cell subsets, including CD19(+)IgD(+) naive B cells, CD19(+)IgD(-)CD27(+) memory B cells, and CD19(lo)CD27(hi) plasmablasts. Moreover, tetanus toxin (TT)-specific B cell proliferation was reduced in DLBCL patients in remission. On the other hand, HA-specific IgG-secreting B cell responses could be stimulated by influenza vaccination in DLBCL patients in remission, demonstrating that the machinery for generating de novo adaptive B cell responses was functional in DLBCL patients in remission. Our results provided insights in normal B cell function in DLBCL patients in remission. |
