By immunocytochemistry and in situ hybridization at the electron microscopy level, and by the PCR technique, we have shown that HIV-1 binds and enters normal sperm; that viral particles, their antigens, and nucleic acid are present in sperm from HIV-1 infected men; and that such sperm can transfer HIV-1 like particles to normal human oocytes. We also present evidence that a galactosylceramide-like compound is present on the sperm membrane and could function as an alternative receptor for HIV.
通过免疫细胞化学、电子显微镜水平的原位杂交以及聚合酶链反应技术，我们已经证明，HIV-1能够结合并进入正常精子；HIV-1感染男性的精子中存在病毒颗粒、其抗原和核酸；并且这种精子能够将HIV-1样颗粒转移至正常人类卵母细胞。我们还提供了证据表明，精子膜上存在一种半乳糖神经酰胺样化合物，它可能作为HIV的替代受体发挥作用。
