Virus infections such as HIV/AIDS and SARS-CoV-2/COVID-19 sicken hundreds of millions of people. The current multiple pandemics have caused unprecedented levels of stress and other life disruptions, which exacerbate substance use disorders, increasing side effects of antiviral drugs and interfering with recovery of individuals suffering from virus infections. Antivirals such as remdesivir, molnupiravir, ritonavir, nirmatrelvir, tenofovir, and darunavir are commonly used to inhibit replication or cell entry for HIV and SARS-CoV-2, thereby inhibiting viral infections. However, some antivirals such as ritonavir of current regimens, especially in combination with other drugs or substance alcohol use, often induced liver injuries causing serious complications. Recently, we have found that remdesivir, ritonavir, and alcohol induce cellular organelle stress, especially endoplasmic reticulum (ER) stress, which is well established not only to cause hepatic cell death but also to compromise immune response leading to a spectrum of liver diseases in a variety of animal models as well as in human patients. Most recently, we discovered with next-generation RNA sequencing that a host protease, RCE1 is a potential off- target of the antiviral drugs. The substrates of RCE1 are limited to a few Rab small GTPase proteins (Rab proteins) with a CaaX motif, which are consequently reduced in the presence of anti-HIV or anti- COVID-19 drugs and reduced much more in drug and alcohol combinations. Because the Rab proteins regulate ER-Golgi trafficking that is essential for cellular organellar homeostasis in the liver, we hypothesize that the antiviral drugs inhibit the host RCE-Rab proteins and induce organelle stress responses that leads to fatty liver injury, and alcohol consumption under stress conditions (e.g., suffering from COVID-19 or frequent quarantine) worsens the drug-induced liver complications. We propose to investigate the pathogenic mechanisms of the RCE-Rab pathway in the antiviral-induced organelle stress and explore pharmaceutical and genetic solutions to mitigate the antiviral drug-induced hepatic injury. Our specific aims are to: (1) validate the mechanistic link of the RCE-Rab pathway with anti-HIV drug and alcohol-induced organelle stress and liver injury, (2) verify whether emerging anti- coronavirus drugs and/or alcohol consumption inhibit the RCE-Rab pathway and induce organelle stress in the liver, (3) explore pharmaceutical and genetic solutions to mitigate the antiviral drug- induced liver injury via testing prophylactic effects of enhanced expression of Rab proteins that compensate the consequence of the antiviral-inhibited host protease, and testing effects of unique enzyme nano-particles that facilitate alcohol removal. Our long-term objectives are to unravel specific pathogenic mechanisms underlying side effects of antivirals so that to improve/modify current antiviral drugs for a better care of the AIDS patients suffering from HIV and SARS-CoV-2 virus infections.

艾滋病毒/艾滋病和SARS-CoV-2/新冠肺炎等病毒感染使数亿人患病。 目前的多重疫情造成了前所未有的压力和其他生活中断， 它们会加剧物质使用障碍，增加抗病毒药物的副作用，并干扰 病毒感染者的康复。抗病毒药物，如瑞昔维韦，莫尼普拉韦， 利托那韦、尼马瑞韦、替诺福韦和达鲁那韦通常用于抑制复制或细胞进入 艾滋病毒和 SARS-CoV-2，从而抑制病毒感染。然而，一些抗病毒药物，如利托那韦， 目前的养生法，尤其是与其他药物或物质酒精联合使用时，通常会导致 肝脏损伤导致严重并发症。最近，我们发现瑞美西韦、利托那韦和 酒精引起细胞器应激，尤其是内质网应激，这是很好的 不仅会导致肝细胞死亡，还会损害免疫反应，从而导致 各种动物模型以及人类患者中的肝病谱。最近， 我们通过下一代RNA测序发现，一种宿主蛋白酶Rce1是一种潜在的关闭- 抗病毒药物的靶标。Rce1的底物仅限于少数Rab小GTP酶蛋白 (RAB蛋白)具有CAAX基序，因此在抗HIV或抗-HIV存在时被减少 新冠肺炎的药物和减少更多的药物和酒精的组合。因为Rab蛋白 调节内质网-高尔基体转运，这对肝脏细胞细胞器内稳态至关重要 假设抗病毒药物抑制宿主RCE-Rab蛋白并诱导细胞器应激 导致脂肪肝损伤的反应，以及在压力条件下饮酒(例如， 患有新冠肺炎或频繁隔离)会加重药物引起的肝脏并发症。我们 建议研究抗病毒诱导的RCE-Rab途径的致病机制 细胞器应激并探索药物和遗传解决方案以减轻抗病毒药物诱导的 肝脏损伤。我们的具体目标是：(1)验证RCE-Rab途径的机制联系 抗HIV药物和酒精诱导的细胞器应激和肝损伤，(2)验证新出现的抗HIV药物是否 冠状病毒药物和/或酒精摄入抑制RCE-Rab途径并诱导细胞器 (3)探索药物和遗传解决方案来缓解抗病毒药物- 通过检测增强表达的Rab蛋白的预防作用来诱导肝损伤 补偿后的抗病毒抑制宿主蛋白水解酶，并检测独特的效果 促进酒精去除的酶纳米颗粒。我们的长期目标是拆解具体的 抗病毒药物副作用的致病机制以改进/修改现有的抗病毒药物 用于更好地护理艾滋病患者，使其感染HIV和SARS-CoV-2病毒。
