Pseudorabies virus (PrV) can infect several animals and causes severe economic losses in the swine industry. Recently, human encephalitis or endophthalmitis caused by PrV infection has been frequently reported in China. Thus, PrV can infect animals and is becoming a potential threat to human health. Although vaccines and drugs are the main strategies to prevent and treat PrV outbreaks, there is no specific drug, and the emergence of new PrV variants has reduced the effectiveness of classical vaccines. Therefore, it is challenging to eradicate PrV. In the present review, the membrane fusion process of PrV entering target cells, which is conducive to revealing new therapeutic and vaccine strategies for PrV, is presented and discussed. The current and potential PrV pathways of infection in humans are analyzed, and it is hypothesized that PrV may become a zoonotic agent. The efficacy of chemically synthesized drugs for treating PrV infections in animals and humans is unsatisfactory. In contrast, multiple extracts of traditional Chinese medicine (TCM) have shown anti-PRV activity, exerting its effects in different phases of the PrV life-cycle and suggesting that TCM compounds may have great potential against PrV. Overall, this review provides insights into developing effective anti-PrV drugs and emphasizes that human PrV infection should receive more attention.
伪狂犬病病毒(PrV)可以感染多种动物,给养猪业造成严重的经济损失。最近,中国频繁报告由 PrV 感染引起的人类脑炎或眼内炎。因此,PrV 可以感染动物,正在成为人类健康的潜在威胁。虽然疫苗和药物是预防和治疗 PrV 爆发的主要策略,但目前没有特效药物,而新的 PrV 变异株的出现降低了经典疫苗的有效性。因此,根除 PrV 具有挑战性。在本综述中,我们介绍并讨论了 PrV 进入靶细胞的膜融合过程,这有助于揭示新的 PrV 治疗和疫苗策略。分析了当前和潜在的 PrV 感染人类的途径,并假设 PrV 可能成为人畜共患病原体。化学合成药物治疗动物和人类 PrV 感染的疗效并不理想。相比之下,多种中药提取物对 PrV 表现出抗活性,在 PrV 生命周期的不同阶段发挥作用,这表明中药化合物可能对 PrV 具有很大的潜力。总的来说,本综述为开发有效的抗 PrV 药物提供了思路,并强调应更加关注人类 PrV 感染。
