Hi

a little different from the immunological approach, but may have some 
validity.

recently, while researching another topic, I came accross a reference for 
tetracycline where it is being used to identify neoplams. Apparently the 
t'cycline is taken up by the cells and allows them to fluoresce.

This means the cell has used t'cycline's cell wall weakness in growing. One 
would assume that at some point this cell would selfdestruct. I take it that 
because of rapid growth rate, the t'cycline is differentially taken in by the 
faster growing cell (than normal ones).....would be interesting to put this 
to practical tests. pretty innocuous.

BTW - on your original idea.....

metchnikov ~1800s had notted a method for enhancing(increasing) macrophage 
populations in an organism. This was done to try to cut down on infections 
after surgeries. The sytem used finely ground charcoal injected into the 
abdominal cavity.....after about a week, macropages were much more numerous 
and ready for any invader. 

Whether this would up the immunological function in such things as cancer 
would be another interesting (pretty cheap) study.

In the realm of pathogens......they have various ways of negating immune 
function (smart little survival tacktic). Overwhelming these organisms with 
an atificially created enhansed immune pressence may prove interesting. After 
all the immune system is very reactionary.

another BTW - metchnikov had studdied pathogenicity's affect on immune 
function in detail...well worth checking out....his book "Immunity in 
Infectious Disease" has bin reprinted. Another good one is "the Comparative 
patrhology of Imflamation"

hope this helps some
