摘要: 目的 观察重组人胰高血糖素类多肽-1(7-36) [rhGLP-1(7-36)] 对小猎兔犬的免疫原性。方法 健康小猎兔犬随机分为rhGLP-1(7-36) 高、中、低剂量组(200 、100 、50μg kg) 和生理盐水对照组,每组6 只, 雌雄各半。皮下注射给药, 每天1 次,每周6 次, 连续9 个月。采用酶联免疫吸附试验(ELISA) 和碱性磷酸酶免疫斑点试验检测犬血清中的抗体。结果 连续给药3 、9 个月及恢复期血清均未发现抗rhGLP-1(7-36) 抗体。结论 长期给予rhGLP-1(7-36) 对小猎兔犬无免疫原性。

Abstract: AIM: To assess the immunogenicity of recombinant glucagons-like peptide-1 (rhGLP-1) (7-36) in Beagle dogs.METHODS: The control group and different doses rhGLP-1(7-36) group dogs were respectively administered with a subcutaneous injection of NS, 200, 100 and 50μg kg of rhGLP-1(7-36) six times weekly for 9 months.Each group had 3 male and 3 female dogs.The antibodies in serum of dog were detected by enzyme linked immunosorbent assay (ELISA) and alkaline phosphatase immunospot assay.RESULTS: The antibodies for the rhGLP-1(7-36) were not detected in all dogs in 3 months and 9 months after dosing of the rhGLP-1(7-36) and in the 1 months after the last dosing.CONCLUSION: rh-GLP-1(7-36) has no immunogenicity on Beagle dogs in the long-term run.

Key words: recombinant glucagons-like peptide-1, immunogenicity, ELISA
