Abstract
  1. A novel anti-inflammatory peptide (residues 204-212) of human recombinant lipocortin 5 (hrLC5) found on the high similarity region with uteroglobin is described. 2. Peptide 204-212 dose-dependently inhibited the contractions of rat isolated stomach strips elicited by porcine pancreatic phospholipase A2 (PLA2). Contractions caused by arachidonic acid (AA), prostaglandin E2 (PGE2) and 5-hydroxytryptamine were not affected. No direct enzyme inhibition was observed in a radiochemical assay. 3. PGE2 release by both human fibroblasts and rat macrophages was reduced by peptide 204-212 in a dose-dependent manner. 4. The development of carrageenin-induced oedema in rats was significantly inhibited by the local administration of peptide 204-212. 5. The pattern and potency of the biological effects of peptide 204-212 are similar to those of antiflammin 2, a lipocortin 1-derived peptide. 6. It is suggested that peptide 204-212 may represent the active site responsible for the anti-inflammatory properties of lipocortin 5.
摘要
  1. 描述了一种在人重组脂皮质素5(hrLC5)上与子宫珠蛋白高度相似区域发现的新型抗炎肽(第204 - 212位氨基酸残基)。2. 肽204 - 212剂量依赖性地抑制猪胰腺磷脂酶A2(PLA2)引起的大鼠离体胃条收缩。花生四烯酸(AA)、前列腺素E2(PGE2)和5 - 羟色胺引起的收缩不受影响。在放射化学分析中未观察到直接的酶抑制作用。3. 肽204 - 212以剂量依赖性方式降低人成纤维细胞和大鼠巨噬细胞释放PGE2。4. 局部给予肽204 - 212可显著抑制角叉菜胶诱导的大鼠水肿。5. 肽204 - 212的生物学效应模式和效力与脂皮质素1衍生肽抗炎症肽2相似。6. 提示肽204 - 212可能代表脂皮质素5抗炎特性的活性位点。
