摘要
HIV相关痴呆是AIDS指征性疾病之一,表现为运动和认知功能障碍。尸检发现皮质萎缩和广泛的神经元细胞丢失,其发病机制还不十分清楚。目前发现HIV蛋白Tat和gp120具有直接和间接的神经毒性。谷氨酸、NO、钙、氧化应激、凋亡和小胶质细胞都参与了HIV相关神经变性的致病过程。本文综述了HIV相关神经毒性致病理论的最新进展,展示了阻止神经丢失和运动/认知功能衰退的潜在治疗干预途径。
As an AIDS-defining illness, HIV are associated with dementia manifests motor and cognitive deficits. Gross postmortem inspection shows cortical atrophy and widespread neuronal loss. Complete understanding of HIV neurotoxicity has been elusive. Both direct and indirect toxic mechanisms have been implicated in the neurotoxicity of the HIV proteins, Tat and gp120. The glutamatergic system, nitric oxide, calcium, oxidative stress, apoptosis, and microglia have all been implicated in the pathogenesis of HIV-related neuronal degeneration. The aim of this review was to summarize the most recent work and provide an overview to the current theories of HIV-related neurotoxicity and potential avenues of therapeutic interventions to prevent the neuronal loss and motor/cognitive deficits previously described.
