摘要: 性别控制是通过人为干预使雌性动物生产出特定性别后代的一项技术。鉴于X精子和Y精子的分离是实现动物性别控制的技术基础,本文基于X精子和Y精子在物理和化学上的特性差异总结和比较了受精前分离精子的新技术,包括流式细胞分离法、免疫学分离法、pH分离法、微流体和纳米技术。免疫学分离法中R848(雷西莫特)激活TLR7/8信号通路是精子分离的潜在方法,旨在为动物性别控制技术提供理论依据。

关键词: 性别控制, X精子, Y精子, 免疫学分离法, TLR7/8

Abstract: Sex control is a technique in which a female animal produces offspring with a specific sex through human intervention. Since the separation of X sperm and Y sperm is the technical basis for the realization of sperm sexing in animals, this paper summarizes and compares the new techniques for the separation of sperm before fertilization, including flow cytometry, immunological approach of sperm sexing, pH separation, microfluidics and nanotechnology. The activation of TLR7/8 signaling pathway by R848 (Resiquimod) in immunological isolation is a potential method for sperm isolation, aiming to provide a theoretical basis for sperm sexing techniques.

Key words: sperm sexing, X sperm, Y sperm, immunological approach of sperm sexing, TLR7/8
