Our previous work showed that a suppressive factor (a protein with large molecular weight) in serum was induced by restraint stress in mice and rats, which suppressed Con A induced lymphocyte proliferation. It was also found that the generation of serum suppressive factor was under control of the central nervous system. Our further study showed that intracerebroventricular (icv) injection of interleukin 1 receptor antagonist (IL-1Ra) antagonised the generation of serum suppressive factor induced by restraint stress and icv injection of interleukin-1 beta (IL-1 beta) increased the generation of the suppressive factor. Our experiment also showed that the serum suppressive factor induced by restraint stress was first made in lymph tissue and then released into blood. The present work was designed to investigate the role of IL-1 in the brain in generation of the suppressive factor in lymph node in mice. Icv injection of IL-1 beta (1 pg/mouse) was shown to significantly increase the generation of the suppressive factor in lymph node. Icv injection of IL-1Ra, however, antagonised generation of the suppressive factor. In mice without restraint stress, both the suppressive factor in serum and in lymph node were found to be induced in dose-dependent manner by icv injection of IL-1 beta. Taken together, these results suggest that IL-1 beta in brain played a very important role in generation of the suppressive factor in lymph node. The positive correlation between the suppressive action of lymph node and of serum added to the evidence that lymph tissue is probably the source of the serum suppressive factor.
