Aj. Zajac et al., THERAPEUTIC VACCINATION AGAINST CHRONIC VIRAL-INFECTION - THE IMPORTANCE OF COOPERATION BETWEEN CD4(-CELLS() AND CD8(+) T), Current opinion in immunology, 10(4), 1998, pp. 444-449
The goal of therapeutic vaccination is to elicit an antiviral immune r
esponse within persistently infected individuals and consequently erad
icate the infection. CD8(+) T cells are potent mediators of viral clea
rance; however, during chronic infections CD4(+) T cell help is requir
ed to sustain antiviral CD8(+) T cell activity. Therapeutic vaccinatio
n should be targeted towards enhancing both CD4(+) and CD8(+) T cell v
irus-specific responses.
