To investigate the particular role of FcγRs in the antibody-mediated protection induced by MCMV-TRP2 vectors [10], we initially aimed to investigate whether FcγRs impact B cell responses including the development of germinal center (GC) B cells and plasma cells, T follicular helper (TFH) cell responses, and antibody responses upon CMV infection. Here, DCT is linked to cytomegalovirus infection.
