Reorganization of host red blood cells by the malaria parasite Plasmodium falciparum enables their sequestration via attachment to the microvasculature. This artificially increases the dwelling time of the infected red blood cells within inner organs such as the brain, which can lead to cerebral malaria. Cerebral malaria is the deadliest complication patients infected with P. falciparum can experience and still remains a major public health concern despite effective antimalarial therapies. Here, the current understanding of the effect of P. falciparum cytoadherence and their secreted proteins on structural features of the human blood-brain barrier and their involvement in the pathogenesis of cerebral malaria are highlighted. Advanced 2D and 3D in vitro models are further assessed to study this devastating interaction between parasite and host. A better understanding of the molecular mechanisms leading to neuronal and cognitive deficits in cerebral malaria will be pivotal in devising new strategies to treat and prevent blood-brain barrier dysfunction and subsequent neurological damage in patients with cerebral malaria.
疟原虫恶性疟原虫通过重组宿主的红细胞,使其通过黏附在微血管上而被隔离。这人为地增加了受感染的红细胞在大脑等内脏器官中的停留时间,从而导致脑疟疾。脑疟疾是恶性疟原虫感染患者最致命的并发症之一,尽管有有效的抗疟治疗方法,但它仍然是一个主要的公共卫生关注点。在这里,我们强调了恶性疟原虫细胞黏附和它们分泌的蛋白对人血脑屏障结构特征的影响,以及它们在脑疟疾发病机制中的作用。还进一步评估了先进的 2D 和 3D 体外模型,以研究寄生虫和宿主之间这种破坏性的相互作用。更好地了解导致脑疟疾中神经元和认知功能障碍的分子机制,对于制定新的策略来治疗和预防脑疟疾患者的血脑屏障功能障碍和随后的神经损伤至关重要。
