    • This invention discloses novel polypeptides having an antigenic determinant or determinants immunologically cross-reactive with determinants of a glycoprotein having a molecular weight of approximately 41,000 daltons, and determinants of a glycoprotein having a molecular weight of approximately 160,000 daltons which are obtained from cells infected with human immunodeficiency virus-1. The invention further discloses novel polypeptides having an antigenic determinant or determinants specific for a glycoprotein having a molecular weight of approximately 41,000 daltons obtained from cells infected with human immunodeficiency virus-1, the polypeptides further having an antigenic determinant or determinants immunologically cross-reactive with at least one glycoprotein having a molecular weight of 25,000 to 35,000 daltons, 45,000 daltons to 60,000 daltons, 80,000 to 100,000 daltons or 180,000 or 220,000 daltons, which are obtained from HSB, St, HeLa and human cells. The novel polypeptides of the invention are useful in methods of interfering with the effects of HIV-1 upon host cells having cell surface polypeptides capable of binding HIV-1. Methods of assay for HIV-1 infection are also disclosed. The invention also discloses peptides having amino acid sequences of about 10 to about 50 amino acids that correspond to at least a portion of an epitope of HIV and methods for developing such biologically active peptides.
    • 本发明公开了具有与具有约41,000道尔顿分子量的糖蛋白的决定簇免疫交叉反应的抗原决定簇或决定簇的新型多肽,以及分子量约为160,000道尔顿的糖蛋白的决定簇,这些糖蛋白是从感染人的细胞获得的 免疫缺陷病毒-1。 本发明进一步公开了具有抗原决定簇或具有特异性的决定簇的新型多肽,该决定簇具有从感染人类免疫缺陷病毒-1的细胞获得的具有约41,000道尔顿的糖蛋白的特异性,所述多肽还具有抗原决定簇或与抗原决定簇免疫交叉反应的决定簇 至少一种由HSB,St,HeLa和人细胞获得的分子量为25,000至35,000道尔顿,45,000道尔顿至60,000道尔顿,80,000至100,000道尔顿或180,000或220,000道尔顿的糖蛋白。 本发明的新型多肽可用于干扰HIV-1对具有能够结合HIV-1的细胞表面多肽的宿主细胞的作用的方法。 还公开了HIV-1感染的测定方法。 本发明还公开了具有对应于HIV表位的至少一部分的约10至约50个氨基酸的氨基酸序列的肽和用于开发此类生物活性肽的方法。
