IL-11 signals through the same gp130 signal transducer as IL-6, despite using a distinct ligand-binding protein. Anti-gp130 antibodies abolished IL-11-induced cell proliferation, protein tyrosine phosphorylation, and junB gene expression in TF-1 cells, whereas anti-IL-6R antibody blocked IL-6 but not IL-11 signaling. |

IL-11 activates JAK tyrosine kinases, MAP kinases, and pp90rsk; pp90rsk is identified as an H7-sensitive protein kinase critical for primary response gene (junB, tis11, tis8, MAP kinase phosphatase) expression induced by IL-11. Tyrosine phosphorylation of Stat91 is involved but insufficient alone for primary response gene activation. |

Histamine synergizes with TGF-β1 to augment IL-11 production in human lung fibroblasts via H1 receptors and a calcium/calmodulin-dependent pretranslational mechanism; H2 receptor agonists and cAMP-dependent pathways were not involved. TGF-β1 alone did not alter cytosolic Ca2+, but histamine caused biphasic Ca2+ increase and sustained oscillations in the presence of TGF-β1. |

IL-11 is the dominant transcriptional response of human fibroblasts to TGFβ1 and is required for TGFβ1's pro-fibrotic effect. IL-11 and IL-11RA are expressed specifically in fibroblasts, where IL-11 drives non-canonical, ERK-dependent autocrine signaling that is required for fibrogenic protein synthesis. Fibroblast-specific Il11 transgene expression or Il-11 injection causes heart and kidney fibrosis in mice, while Il11ra1 deletion protects against fibrosis. |

A specific IL11RA missense mutation (p.Arg296Trp) rendered the receptor unable to mediate IL-11 signaling in cell transfection experiments, demonstrating that IL-11 signaling restricts suture fusion and tooth number. |

Hypoxic cancer cells express functional IL-11Rα, enabling autocrine IL-11 signaling that promotes anchorage-independent growth and tumor growth in vivo; silencing IL11 or STAT1 abrogated these hypoxia-induced effects. |

IL-11 signals in fibroblasts via IL6ST (gp130); IL-11-induced ERK activation (not STAT3) drives fibrogenesis and myofibroblast transformation. ERK activates an mTOR/P70RSK protein translation axis; selectivity for Collagen 1 synthesis is ascribed to an EPRS-regulated ribosome stalling mechanism. STAT3 inhibition caused proteotoxic ER stress and cell death unrelated to fibrogenesis. Recombinant human IL-11 increases pSTAT3 in Il11ra1-null fibroblasts, indicating off-target STAT3 effects of species-mismatched recombinant protein. |

IL-11 binds the membrane-bound IL-11 receptor (IL-11R), which recruits a gp130 homodimer for classic signaling. The rhomboid intramembrane protease RHBDL2 (in addition to previously known ADAM10) cleaves IL-11R between Ala-370 and Ser-371, generating soluble IL-11R (sIL-11R) that enables IL-11 trans-signaling via gp130 homodimerization. RHBDL2 can cleave IL-11R in the early secretory pathway. The human mutation IL-11R-A370V prevents RHBDL2-mediated cleavage but not classic signaling. |
