For example, in BALB/c mice, the tetravalent dengue ED3-based DNA vaccine induced one cross-reactive CD4+ T-cell epitope shared by DENV-1,?2, and?3 and one serotype-specific CD4+ T-cell epitope to DENV-4
For example, in BALB/c mice, the tetravalent dengue ED3-based DNA vaccine induced one cross-reactive CD4+ T-cell epitope shared by DENV-1,?2, and?3 and one serotype-specific CD4+ T-cell epitope to DENV-4. to DENV-2 was boosted in rMV-TDV-immunized mice after challenge. This result suggested that pre-existing DENV-3-dominated T-cell reactions did not cross-react, but a DENV-2-specific IFN- response, which was undetectable during immunization, was recalled. Interestingly, this recalled T-cell response identified the epitope in the same position as the E349?363 Miglustat hydrochloride but in the DENV-2 serotype. This result suggested that immunodomination occurred in the CD4+ T-cell epitopes between dengue serotypes after rMV-TDV vaccination and resulted in a DENV-3-dominated CD4+ T-cell response. Even though significant increase in IgG against both DENV-2 and -3 suggested that cross-reactive antibody reactions were boosted, the improved neutralizing antibodies…
