美国得克萨斯大学西南医学中心的实验室研究显示，单克隆抗体（ＭｃＡｂ）结合蓖麻毒素亚单位能杀死９９％以上潜伏人类免疫缺陷症病毒（ＨＩＶ）的细胞。 研究者从健康志愿者中获取Ｔ细胞，用实验室培养的ＨＩＶ感染它们，杀死能产生ＨＩＶ的细胞，留下带有潜伏ＨＩＶ的细胞， Laboratory studies at the University of Texas Southwestern Medical Center have shown that monoclonal antibodies (McAbs) that bind to ricin toxin subunits can kill more than 99% of cells that harbor latent human immunodeficiency virus (HIV). The researchers took T cells from healthy volunteers, infected them with lab-grown HIV, killed HIV-producing cells, left cells with latent HIV,
