Stress is generally classified as any mental or emotional strain resulting from difficult circumstances, and can manifest in the form of depression, anxiety, post-traumatic stress disorder (PTSD), or other neurocognitive disorders. Neurocognitive disorders such as depression, anxiety, and PTSD are large contributors to disability worldwide, and continue to affect individuals and communities. Although these disorders affect men and women, women are disproportionately represented among those diagnosed with affective disorders, a result of both societal gender roles and physical differences. Furthermore, the incidence of these neurocognitive disorders is augmented among People Living with HIV (PLWH); the physical ramifications of stress increase the likelihood of HIV acquisition, pathogenesis, and treatment, as both stress and HIV infection are characterized by chronic inflammation, which creates a more opportunistic environment for HIV. Although the stress response is facilitated by the autonomic nervous system (ANS) and the hypothalamic pituitary adrenal (HPA) axis, when the response involves a psychological component, additional brain regions are engaged. The impact of chronic stress exposure and the origin of individual variation in stress responses and resilience are at least in part attributable to regions outside the primary stress circuity, including the amygdala, prefrontal cortex, and hippocampus. This review aims to elucidate the relationship between stress and HIV, how these interact with sex, and to understand the physical ramifications of these interactions.
压力通常被归类为任何因困难环境而产生的精神或情绪紧张,其表现形式可能是抑郁、焦虑、创伤后应激障碍(PTSD)或其他神经认知障碍。抑郁、焦虑和 PTSD 等神经认知障碍是全球残疾的主要原因之一,继续影响着个人和社区。尽管这些障碍影响男性和女性,但在被诊断患有情感障碍的人群中,女性的比例不成比例,这是社会性别角色和身体差异共同作用的结果。此外,这些神经认知障碍在艾滋病毒感染者(PLWH)中更为普遍;压力的身体影响增加了 HIV 感染的可能性、发病机制和治疗效果,因为压力和 HIV 感染都以慢性炎症为特征,这为 HIV 创造了一个更有利的环境。尽管自主神经系统(ANS)和下丘脑-垂体-肾上腺(HPA)轴促进了应激反应,但当反应涉及心理成分时,会涉及其他大脑区域。慢性应激暴露的影响以及应激反应和弹性的个体差异的起源至少部分归因于主要应激回路之外的区域,包括杏仁核、前额叶皮层和海马体。本综述旨在阐明压力与 HIV 之间的关系,以及这些因素如何与性别相互作用,并了解这些相互作用的身体影响。
