我们假设帕金森病(PD)的发病机制可以分为三个时间阶段。在第一阶段,“触发器”,如病毒感染或环境毒素,引发大脑和/或外周组织中的疾病过程。然而,单独的触发因素可能是不够的,需要“促进因素”如外周炎症来发展PD病理。一旦这种疾病出现,“破坏者”会刺激进一步的神经变性并加剧症状。加重因素包括自噬受损和α-突触核蛋白病理的细胞间传播。我们认为,临床试验需要考虑这三个阶段,并在疾病过程的适当阶段针对潜在的治疗方法,以便有效。
We hypothesize that Parkinson’s disease (PD) pathogenesis can be divided into three temporal phases. During the first phase, “triggers”, such as viral infections or environmental toxins, spark the disease process in the brain and/or peripheral tissues. Triggers alone, however, may be insufficient, requiring “facilitators” like peripheral inflammation for PD pathology to develop. Once the disease manifests, “aggravators” spur further neurodegeneration and exacerbate symptoms. Aggravators are proposed to include impaired autophagy and cell-to-cell propagation of α-synuclein pathology. We believe clinical trials need to consider these three phases and target potential therapies at the appropriate stage of the disease process in order to be effective.
