AB In the present study, the requirements and characteristics for the
production of IL-13 by human T cells, T cell clones and B cells were
determined and compared with those of IL-4. IL-13 was produced by human
CD4+ and CD8+ T lymphocyte subsets isolated from peripheral blood
mononuclear cells and by CD4+ and CD8+ T cell clones. CD4+ T cell clones
belonging to Th0, Th1-like and Th2-like subsets produced IL-13 following
antigen-specific or polyclonal activation. In addition, EBV-transformed
B cell lines expressed IL-13 mRNA and produced small amounts of IL-13
protein. Expression of IL-13 mRNA and production of IL-13 protein by
peripheral blood T cells and T cell clones was induced rapidly and was
relatively long lasting, whereas IL-4 production by these cells was
transient. In addition, IL-13 mRNA expression was induced by modes of
activation that failed to induce IL-4 mRNA expression. IL-13 shares many
biological activities with IL-4 which is compatible with the notion that
the IL-13 and IL-4 receptors share a common component required for
signal transduction. However, IL-13 lacks the T cell-activating
properties of IL-4. Here we have shown that this is related to the fact
that T cells fail to bind radiolabeled IL-13 and do not express the
IL-13-specific receptor component. Taken together, these results
indicate that the differences in expression and biological activities of
IL-4 and IL-13 on T cells may have consequences for the relative roles
of these cytokines in the immune response.
