IL-13 是过敏性炎症的关键效应细胞因子。它由多种细胞类型产生,包括肥大细胞、嗜碱性粒细胞和 TH2 细胞。在肥大细胞和嗜碱性粒细胞中,其诱导可以通过免疫球蛋白受体或细胞因子的交联来刺激。 IL-1 家族成员 IL-33 和 IL-18 与肥大细胞和嗜碱性粒细胞诱导 IL-13 产生有关。在 CD4 TH2 细胞中,IL-33 介导的 IL-13 产生需要同时激活信号转导器和转录激活剂 (STAT) 5。在这里,我们讨论了肥大细胞和嗜碱性粒细胞中细胞因子诱导的 IL-13 产生是否遵循与 TH2 细胞相同的逻辑:需要 2 个独立的信号。方法:通过产生细菌人工染色体 (BAC) 转基因 IL-13 报告小鼠,我们测量了肥大细胞和嗜碱性粒细胞中 IL-13 的产生。在从腹腔收获的肥大细胞中,IL-13 的产生需要 2 种细胞因子信号:IL-33 和 IL-3。在骨髓肥大细胞中,IL-13 的产生需要 IL-33,但对 STAT5 诱导剂的需求很难评估,因为这些细胞需要持续存在 IL-3(一种 STAT5 激活剂)才能生存。培养物中较差的 STAT5 诱导剂(IL-4 或干细胞因子)会导致 IL-33 攻击后 IL-13 的产生减少,但添加外源性 IL-3 会增强 IL-13 的产生。这意味着骨髓来源的肥大细胞,如腹膜肥大细胞和 TH2 细胞,需要 IL-1 家族成员和 STAT5 诱导剂的刺激才能分泌 IL-13。嗜碱性粒细胞遵循相同的规则;脾嗜碱性粒细胞响应 IL-18 或 IL-33 加 IL-3 产生 IL-13。肥大细胞和嗜碱性粒细胞的最佳 IL-13 产生需要 2 个细胞因子信号。
IL-13 is a critical effector cytokine for allergic inflammation. It is produced by several cell types, including mast cells, basophils, and TH2 cells. In mast cells and basophils its induction can be stimulated by cross-linkage of immunoglobulin receptors or cytokines. The IL-1 family members IL-33 and IL-18 have been linked to induction of IL-13 production by mast cells and basophils. In CD4 TH2 cells IL-33–mediated production of IL-13 requires simultaneous signal transducer and activator of transcription (STAT) 5 activation. Here we have addressed whether cytokine-induced IL-13 production in mast cells and basophils follows the same logic as in TH2 cells: requirement of 2 separate signals. Methods: By generating a bacterial artificial chromosome (BAC) transgenic IL-13 reporter mouse, we measured IL-13 production in mast cells and basophils. In mast cells harvested from peritoneal cavities, 2 cytokine signals are required for IL-13 production: IL-33 and IL-3. In bone marrow mast cells IL-13 production requires IL-33, but the requirement for a STAT5 inducer is difficult to evaluate because these cells require the continuous presence of IL-3 (a STAT5 activator) for survival. Poorer STAT5 inducers in culture (IL-4 or stem cell factor) result in less IL-13 production on IL-33 challenge, but the addition of exogenous IL-3 enhances IL-13 production. This implies that bone marrow–derived mast cells, like peritoneal mast cells and TH2 cells, require stimulation both by an IL-1 family member and a STAT5 inducer to secrete IL-13. Basophils follow the same rule; splenic basophils produce IL-13 in response to IL-18 or IL-33 plus IL-3. Optimal IL-13 production from mast cells and basophils requires 2 cytokine signals.
