摘　　要：极低密度脂蛋白受体(VLDLR)是一类不可缺少的膜表面受体蛋白,在哺乳动物体内主要是将肝脏合成的甘油三酯和胆固醇转移到肝外组织供机体利用。在家禽中,VLDL和卵黄蛋白原(VTG)是占卵黄重量30%以上的两个重要的卵黄前体物质,它们通过VLDLR介导的内吞作用被生长中的卵母细胞吸收,从而加快卵泡的发育和卵黄的形成。目前关于VLDLR基因对家禽卵泡发育及蛋品质相关性状的调控取得了大量的研究进展,文章综述了VLDLR基因在家禽卵泡发育及蛋品质相关性状形成过程的研究进展,以期为后续相关研究提供参考和新的思路。Very low density lipoprotein receptor(VLDLR) is an indispensable membrane-surface receptor protein,which mainly transfers triglycerides and cholesterol synthesized by the liver to the extracellular tissues for the body use in mammals. Very low density lipoprotein(VLDL) and vitellogenin(VTG), the two key yolk precursors, accounting for more than 30% of yolk weight, are taken up by growing oocytes via VLDLR-mediated endocytosis. This process is essential for the development of oocyte and yolk formation in poultry. A great many previous studies showed that VLDLR gene could regulate the poultry follicular development and egg production related traits. In this study, the research progress of VLDLR gene in poultry follicular development and egg quality related trait formation were reviewed to provide references and new ideas for the subsequent related research.
