应用动物模型评价重组人乳铁蛋白(rhLF)的致敏性。将32只Brown Norway(BN)大鼠随机分为4组,分别给予卵清蛋白(OVA)(阳性对照)、重组人LF(rhLF)、牛乳铁蛋白(bLF)和生理盐水(阴性对照),每天灌胃给药42 d。检测特异性抗体(IgE、IgG、IgG2a)水平、血细胞计数、血压及重要脏器病理变化,并进行比较。与其他组相比,OVA刺激BN大鼠的特异性IgE和嗜酸性粒细胞(EO)计数显著升高(p <0.05),血压降低(p<0.05),肺损伤更严重。动物对rhLF和bLF无明显的体液、细胞和局部过敏反应。结果表明rhLF对动物的致敏性较弱,具有进一步鉴定研究的潜在价值。
The assessment of allergenicity of recombinant human lactoferrin (rhLF) using an animal model for its extensive use. In this study, 32 Brown Norway (BN) rats were divided into four groups that were exposed to ovalbumin (OVA) (positive control), rhLF, bovine lactoferrin (bLF) and saline (negative control), respectively, with daily intragastric administration for 42 days. The level of specific antibody (IgE, IgG and IgG2a), blood cell counts, blood pressure and pathology of important organs were measured and compared among the groups. OVA stimulated significant higher levels of specific-IgE and eosinophil (EO) counts (p <0.05), lower blood pressure (p<0.05) and more serious lesion in the lung of BN rats compared to the other groups. And the animals did not show obvious humeral, cell-mediated and local allergic response to rhLF and bLF. The results demonstrate a weak allergenicity of rhLF on the animal and reveal its potential value for further identified study.
