proliferating lymphocytes in peripheral blood and CD25 expression

Hallo,

I would like to ask if anybody knows about the relationship of expression of classical 
proliferation markers (like Ki-67 or the transferrin receptor) and CD25 (which is also an activation marker) in peripheral blood lymphocytes. 
Do they give similar results, do they correlate or are they totally independent of each 
other ?
If they do correlate, how would an increased activation status of the immune system 
(increased percentage or number of HLA-DR+ cells) be expected to influence that 
relationship ?

Many thanks in advance.

Kind regards,
