* 病理学病理学
* 血液学血液学

背景情况:

*全球高血压患病率正在上升,这给医疗保健带来了挑战,特别是在疟疾流行地区.
*高血压对疟疾易感性的影响尚未得到充分研究,尽管红细胞 (RBC) 是疟疾寄生虫的宿主.
* 之前的工作表明高血压与异常的红细胞生理和贫血有关.

研究的目的:

* 调查高血压是否使个人易患疟疾感染.
* 测试高血压患者与红细胞异常有更高的风险感染等杆菌的假设.

主要方法:

*使用了正常血压 (BPN/3J) 和高血压 (BPH/2J) 的小鼠.
*红细胞生理学的特征是,随后感染Plasmodium yoelii (P. yoelii).

主要成果:

*高血压BPH小鼠表现出微细胞贫血,抗性红细胞和膜刚度增加.
* BPH小鼠的红血细胞脂质组成发生了变化,并且更多的不成熟的红血细胞 (网细胞) 容易感染P. yoelii.
* BPH小鼠在感染时显示出更大的体重减轻,持续的寄生素血,贫血和炎症反应.

结论:

*高血压中异常的红细胞生理学有助于增加对P. yoelii感染的易感性.
*高血压通过改变红细胞功能,加剧了与疟疾相关的病理.

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
