IL-6 controls the innate immune response against Listeria monocytogenes via classical IL-6 signaling.
The cytokine IL-6 plays a protective role in immune responses against bacterial infections. However, the mechanisms of IL-6-mediated protection are only partially understood. IL-6 can signal via the IL-6R complex composed of membrane-bound IL-6Rα (mIL-6Rα) and gp130. Owing to the restricted expression of mIL-6Rα, classical IL-6 signaling occurs only in a limited number of cells such as hepatocy...
متن کاملAlthough IL-6 trans-signaling is sufficient to drive local immune responses, classical IL-6 signaling is obligate for the induction of T cell-mediated autoimmunity.
IL-6-mediated T cell-driven immune responses are associated with signaling occurring through the membrane-bound cognate receptor α-chain (mIL-6Rα). Once formed, IL-6-mIL-6Rα complexes induce the homodimerization and subsequent phosphorylation of the ubiquitously expressed signal-transducing protein, gp130. This signaling event is defined as classical IL-6 signaling. However, many inflammatory p...
متن کاملIL-6 Trans-Signaling via the Soluble IL-6 Receptor: Importance for the Pro-Inflammatory Activities of IL-6
Interleukin-6 (IL-6) is a cytokine with many activities. It has functions in the regulation of the immune system and the nervous system. Furthermore, IL-6 is involved in liver regeneration and in the metabolic control of the body. On target cells, IL-6 binds to an 80 kDa IL-6 receptor (IL-6R). The complex of IL-6 and IL-6R associates with a second protein, gp130, which thereupon dimerizes and i...
متن کاملHuman marrow stromal cells: response to interleukin-6 (IL-6) and control of IL-6 expression.
Production of interleukin-6 (IL-6) by marrow stromal cells from human long-term marrow cultures and from stromal cells transformed with simian virus 40 was examined. As with other cultured mesenchymal cells, unstimulated stromal cells produced undetectable amounts of IL-6 mRNA when assayed by Northern blots. However, within 30 minutes after exposure of transformed marrow stromal cells to the in...
متن کاملArid5a controls IL-6 mRNA stability, which contributes to elevation of IL-6 level in vivo.
Posttranscriptional regulation of IL-6 has been largely uncharacterized, with the exception of the ribonuclease Regnase-1, which prevents autoimmunity by destabilizing IL-6 mRNA. Here, we identified AT-rich interactive domain-containing protein 5A (Arid5a) as a unique RNA binding protein, which stabilizes IL-6 but not TNF-α mRNA through binding to the 3' untranslated region of IL-6 mRNA. Arid5a...
