Certainly the generation of CTL responses are dependent on helper-inducer
activity
but whether every antigen response by CD8 cells is absolutely governed by
CD4 responses hmmm i'm sure there are model systems that show that it
ain't i just can't think of one.

-in general TH1 cells help cytotoxic reponses and Th2 cells help Ab
responses but the lines aren't solid here either.
