摘要:

目的采用微环DNA技术制备特异性的抗人乳头瘤病毒(human papillomavirus, HPV)16/18?L1卵黄抗体(eimmunoglobulin of egg yolk, IgY),为临床HPV感染提供一种新型的抗体治疗方法。方法利用家鸡密码子偏好,通过微环DNA技术构建微环DNA母质粒,通过工程菌(ZYCY10P3S2T22)诱导制备HPV16/18-L1微环DNA (MC.HPV16/18?L1)表达载体;MC.HPV16/18?L1作为免疫原免疫产蛋鸡制备抗HPV16/18?L1高效价的卵黄抗体。结果通过微环DNA技术成功制备了高效价的抗HPV16/18?L1卵黄抗体,其抗体效价可达1∶4 096;该卵黄抗体制备的抗HPV凝胶产品经临床观察,转阴效果可达88.6%。结论微环DNA作为一种新型的非病毒基因表达载体可用于高效价卵黄抗体的制备,采用微环DNA技术制备抗HPV抗体产品为临床HPV治疗提供了新思路。

Abstract:

ObjectiveTo prepare specific anti-HPV16/18-L1 egg yolk antibody (IgY) by using minicircle DNA technology, and to provide a new antibody treatment method for clinical HPV infection.MethodsUsing chicken codon preference, the minicircle DNA mother plasmid was constructed by minicircle DNA technology, and the HPV16/18-L1 minicircle DNA (MC. HPV16/18-L1) expression vector was induced and prepared by engineering bacteria (ZYCY10P3S2T22); MC. HPV16/18-L1 was used as an immunogen to immunize laying hens to prepare egg yolk antibody with high titer against HPV16/18-L1.ResultsThe anti-HPV16/18-L1 egg yolk antibody with high titer was successfully prepared by minicircle DNA technology, and its antibody dilution reached 1:4 096; the anti-HPV gel product prepared by the egg yolk antibody was clinically observed, and the negative effect was up to 88.6%.ConclusionMinicircle DNA, as a new type of non-viral gene expression vector, can be used for the preparation of high-titer egg yolk antibody. The preparation of anti-HPV antibody products by minicircle DNA technology provides a new idea for clinical HPV treatment.
