"Conditioning"--IL-1 et al.

I've discussed the idea of IL-1 conditioning with Ader (he was one of
my speakers at the May 2 conference on "Neuropsychology and the
Neuroimmune Dialogue"--announced to bionet.immunology).  He agreed it
is a reasonable possibility, but did not know of any direct evidence. 
Much of his own work looks at agents or actions farther "downstream",
less on intermediate steps.

Maybe I should emphasize and make explicit: I'm really not interested
in "immune responses" in general, and certainly not in (e.g.) influence
of social or behavioral factors on health, resistance to disease, etc.
My interest is rather narrowly focused on IL-1, TNF, NO (and/or NOS),
and mast cells, and possible long-range "conditioning" (Pavlovian or
otherwise); on a time-order PERHAPS approaching that of responses based
on antigen recognition, but not this mechanism.

I'll certainly check out Lyle and Hiramoto.  Thanks!
