小鼠肥大细胞蛋白酶11(mMCP-11)是最近发现的小鼠肥大细胞类胰蛋白酶家族成员。这种类胰蛋白酶优先由嗜碱性粒细胞产生,而不是由肥大细胞表达的其他成员,但不是嗜碱性粒细胞。虽然血液循环中的嗜碱性粒细胞一直被认为是组织中肥大细胞的次要和多余的亲属,但最近的研究表明,嗜碱性粒细胞和肥大细胞在体内发挥不同的作用。为了探索嗜碱性粒细胞来源的mMCP-11在体内的作用,我们制备了重组mMCP-11及其蛋白酶死亡突变体。皮下注射野生型mMCP-11而非突变体可诱导水肿性皮肤肿胀,并以剂量依赖性方式增加微血管通透性。皮损中未检测到明显的促炎细胞浸润,包括中性粒细胞和嗜酸性粒细胞。用吲哚美辛(一种环氧合酶抑制剂)预处理小鼠,皮肤肿胀被消除,这表明野牡丹素对微血管渗漏的主要贡献。值得注意的是,即使在肥大细胞缺陷型小鼠中也引起皮肤肿胀,表明肥大细胞对mMCP-11诱导的皮肤肿胀敏感。因此,嗜碱性粒细胞衍生的mMCP-11可以诱导微血管渗漏,通过肥大细胞非依赖性的方式,并可能有助于嗜碱性粒细胞介导的炎症反应的发展。
Mouse mast cell protease 11 (mMCP-11) is the most recently identified member of the mouse mast cell tryptase family. This tryptase is preferentially produced by basophils in contrast to other members that are expressed by mast cells but not basophils. Although blood-circulating basophils have long been considered as minor and redundant relatives of tissue-resident mast cells, recent studies illustrated that basophils and mast cells play distinct roles in vivo. To explore the in vivo role of basophil-derived mMCP-11, here we prepared recombinant mMCP-11 and its protease-dead mutant. Subcutaneous injection of the wild-type mMCP-11 but not the mutant induced edematous skin swelling with increased microvascular permeability in a dose-dependent manner. No apparent infiltration of proinflammatory cells including neutrophils and eosinophils was detected in the skin lesions. The cutaneous swelling was abolished by the pretreatment of mice with indomethacin, a cyclooxygenase inhibitor, suggesting the major contribution of prostaglandins to the microvascular leakage. Of note, the cutaneous swelling was elicited even in mast cell-deficient mice, indicating that mast cells are dispensable for the mMCP-11-induced cutaneous swelling. Thus, basophil-derived mMCP-11 can induce microvascular leakage via prostaglandins in a mast cell-independent manner, and may contribute to the development of basophil-mediated inflammatory responses.
