Different Antigen-Specific CD4+ and CD8+ T-Cell Response against HCMV Proteins in Pregnant Women with Primary Infection and in Control Subjects with Remote Infection

: Human cytomegalovirus (HCMV) is the most frequent cause of congenital infections. The HCMV-specific T-cell response in primary infection may help define reliable correlates of immune protection in pregnancy. In this study, the antigen-specific T-cell response against different HCMV proteins (IE-1, pp65, gB, gHgLpUL128L) was investigated in pregnant women with primary infection and in control subjects with remote infection to identify possible components of a vaccine.
