AB Immunization of mice with peptide constructs, consisting of a
determinant recognized by T cytotoxic cells colinearly linked to a
determinant recognized by T helper cells (TDc-TDh) was able to induce
cytotoxic T lymphocytes in vivo. Interestingly, this induction could be
achieved in the absence of adjuvant in non-depleted as well as in
CD4(+)-cell-depleted BALB/c mice. In the latter case, induction took
place simultaneously with the activation of CD8+ T helper cells specific
for a TDh contained within the sequence of the TDc RIQRGPGRAFVTIGK from
the immunodominant V3 loop of HIV1 gp120. The possible implications of
these findings in HIV infection and AIDS disease are discussed.
