人类免疫缺陷病毒1型(HIV-1)感染大脑通常会导致智力的毁灭性丧失。令人惊讶的是,HIV-1在没有显著感染神经元、星形胶质细胞和少突胶质细胞的情况下诱发了这种脑功能障碍。HIV-1在大脑中的靶点是巨噬细胞,它通常起吞噬、抗原呈递和免疫调节细胞的作用。这些细胞是如何产生如此严重的认知和运动脑损伤的?这里. Hans Nottet和霍华德Gendelman提出,HIV-1可以穿透分化中的巨噬细胞内的血脑屏障,巨噬细胞一旦进入大脑就会被免疫激活,并分泌高水平的神经毒素。慢性亚临床疾病是由星形胶质细胞调节巨噬细胞效应子功能引起的。最终,内源性控制机制被破坏,导致部分受影响者的运动和精神障碍。三分之一的成人和一半的儿童艾滋病患者将不可避免地发展神经功能障碍,直接归因于人类免疫缺陷病毒1型(HIV-1)感染的中枢神经系统(CNS)。脑和脊髓的HIV-1感染的一系列临床和病理疾病表现(统称为HIV-1相关的认知/运动复合体或HIV痴呆)是AIDS的突出特征(参考文献2)。疾病往往是微妙的,包括精神和身体的放缓,以及认知能力下降。随后会出现明显的记忆丧失和阅读或在工作和/或家中执行简单任务的困难。运动症状可能伴随发生,表现为笨拙,进展为步态障碍伴严重虚弱。不可避免地,花斑痴呆伴失禁,幻觉,癫痫,然后昏迷。
Infection of the brain with human immunodeficiency virus 1 (HIV-l) often leads to the devastating loss of mental faculties. Surprisingly, HIV-1 elicits such brain dysfunction without significantly infecting neurons, astrocytes and oligodendroglia. The target for HIV-1 in the brain is the macrophage, which usually functions as a phagocytic, antigen-presenting and immune-regulatory cell. How can these cells produce such serious cognitive and motor brain impairments? Here. Hans Nottet and Howard Gendelman propose that HIV-1 penetrates the blood-brain barrier inside differentiating macrophages, which become immune activated once inside the brain, and secrete high levels of neurotoxins. Chronic, subclinical disease results by astrocyte regulation of macrophage effector functions. Ultimately, endogenous control mechanisms break down, leading to motor and mental impairments in some affected subjects.A third of the adults and half of the children with AIDS will inevitably develop neurological impairments directly attributable to human immunodeficiency virus 1 (HIV-l) infection of the central nervous system (CNS). A range of clinical and pathological disease manifestations of HIV-l infection of the brain and spinal cord’(termed, collectively, the HIV-l-associated cognitive/motor complex or HIV dementia) is a prominent feature of AIDS (Ref. 2). Disease is often subtle, and includes mental and physical slowing, and diminished cognition. Complaints of overt memory loss and difficulties with reading or carrying out simple tasks at work and/or at home can follow. Motor symptoms may occur concomitantly and are manifested by clumsiness progressing to gait disturbances with profound weakness. Inevitably, florid dementia with incontinence, hallucinations, seizures, then comas ensues;.
