Herpes simplex virus (HSV) infections manifest as recurrent oral or genital mucosal lesions, meningoencephalitis, corneal blindness, and perinatal disease. Subunit vaccines have advanced into the clinic without success. None were tested preclinically in male mice. We compared a single-cycle candidate vaccine deleted in HSV-2 glycoprotein D (ΔgD-2) and subunit gD-2 or gD-1 protein vaccines in a male murine skin model. The ΔgD-2 provided complete protection against 10 times the lethal dose of HSV-1 or HSV-2 clinical isolates, and no latent virus was detected, whereas gD-1- and gD-2-adjuvanted proteins provided little or no protection. Protection correlated with Fc receptor activating but not neutralizing antibody titers.
单纯疱疹病毒 (HSV) 感染表现为复发性口腔或生殖器黏膜病变、脑膜炎脑炎、角膜盲和围产期疾病。亚单位疫苗已进入临床阶段,但未成功。在雄性小鼠中,没有一种疫苗在临床前进行过测试。我们在雄性小鼠皮肤模型中比较了一种单周期候选疫苗(缺失 HSV-2 糖蛋白 D (ΔgD-2) 的疫苗)和亚单位 gD-2 或 gD-1 蛋白疫苗。ΔgD-2 对 10 倍致死剂量的 HSV-1 或 HSV-2 临床分离株提供完全保护,未检测到潜伏病毒,而 gD-1 和 gD-2 佐剂蛋白提供的保护很少或没有。保护与 Fc 受体激活而不是中和抗体滴度相关。
