Specific cell-mediated responses against gp120-expressing target cells by splenic effectors from co-immunized mice Mice were given two monthly injections with either SV(mIL-15), SV(gp120) or both cytokine and antigen sequentially or simultaneously IP. One month after the final inoculation(s), unselected spleen cells were assayed for specific cytolytic activity against gp120-expressing clone 24 cells labeled with ⁵¹Cr, as described in Methods. Results shown here represent ≥ 3 independent determinations per data set.
