Therefore, the aim of the present study was to investigate the effects of oral administration of JTT in anti-vaccinia cellular immunity in tumour-bearing hosts to evaluate the induction of human immunodeficiency virus (HIV)-1 envelope glycoprotein (gp) 160-derived epitope peptide P18-I10-specific CD8+ T cells in mice inoculated with murine recombinant vaccinia virus expressing HIV-1 gp160 (vSC25). The gene discussed is CD8A; the disease is neoplasm.
