创伤后应激障碍(PTSD)在暴露于创伤应激的一部分人中发展。除了明确的心理和行为症状外,一些创伤后应激障碍患者还表现出炎症标志物的浓度升高,包括C-反应蛋白、白细胞介素6和肿瘤坏死因子-α。此外,创伤后应激障碍通常与免疫相关的疾病,如心脏新陈代谢障碍和自身免疫性疾病并存。许多因素,包括终生创伤负担、生物性别、遗传背景、代谢条件和肠道微生物区系,可能会导致创伤后应激障碍的炎症。重要的是,炎症可以影响大脑中与恐惧、焦虑和情绪调节相关的区域的神经回路和神经递质信号。鉴于创伤后应激障碍与免疫系统之间的联系,目前正在进行研究,以评估抗炎治疗对创伤后应激障碍患者的疗效。了解创伤后应激障碍和免疫系统之间的复杂相互作用对于未来发现诊断和治疗工具至关重要。
Posttraumatic stress disorder (PTSD) develops in a subset of individuals upon exposure to traumatic stress. In addition to well-defined psychological and behavioral symptoms, some individuals with PTSD also exhibit elevated concentrations of inflammatory markers, including C-reactive protein, interleukin-6, and tumor necrosis factor-α. Moreover, PTSD is often co-morbid with immune-related conditions, such as cardiometabolic and autoimmune disorders. Numerous factors, including lifetime trauma burden, biological sex, genetic background, metabolic conditions, and gut microbiota, may contribute to inflammation in PTSD. Importantly, inflammation can influence neural circuits and neurotransmitter signaling in regions of the brain relevant to fear, anxiety, and emotion regulation. Given the link between PTSD and the immune system, current studies are underway to evaluate the efficacy of anti-inflammatory treatments in those with PTSD. Understanding the complex interactions between PTSD and the immune system is essential for future discovery of diagnostic and therapeutic tools.
