The signaling transduction mechanism mediated by tumor necrosis factor-alpha (TNF-alpha) in the alveolar epithelium is not well characterized. It was subsequently hypothesized that recombinant murine TNF-alpha (rmTNF-alpha) selectively regulates the inhibitory kappa B (I kappa B-alpha)/nuclear factor-kappa B (NF-kappa B) pathway and interferes with the endogenous biosynthesis of pro-inflammatory (stimulatory) and anti-inflammatory (inhibitory) cytokines. The cytokine rmTNF-alpha induced, in a time- and dose-dependent manner, the degradation of I kappa B-alpha within the cytosolic compartment, an effect associated with up-regulating its phosphorylation. This allowed the biphasic regulation of selective NF-kappa B subunit nuclear translocation, thereby mediating a dual excitatory mechanism on NF-kappa B activation. The immunoregulatory effect of rmTNF-alpha was associated with a time-dependent induction of pro-inflammatory [interleukin (IL)-1 beta, IL-6 and TNF-alpha] and anti-inflammatory (IL-10) cytokine biosynthesis. These results indicate a novel involvement of an I kappa B-alpha/NF-kappa B-sensitive pathway mediating the effect of TNF-alpha, which is associated with an autocrine, endogenous mechanism mediating the regulation of cytokine signaling.
