CTL, Helper cells and B-cells etc

[Deva Patil]

Dear All,

I have following general questions in Immunology and would appreciate
your attention.

1)  Is the response of CD8+ CTL response dependent on CD4+ Helper cells?

2) If so, within the CD4+ Helper cells, is there a subpopulation
specifically interacting with CD8+ CTLs
and another subpopulation interacting with B cells?

Thank you very much for your time.
