程序性细胞死亡(PCD)途径仍然在寄生原生动物的研究不足,尽管他们提供了新的治疗发展的潜在目标。在高等真核生物中最好理解的PCD途径是细胞凋亡,尽管新出现的证据也指出自噬在某些生理环境中是死亡的介导者。生物信息学分析结合生物化学和细胞生物学研究表明,寄生原生动物具有PCD的能力,包括原始形式的细胞凋亡。弓形虫的最新研究和疟原虫的新数据表明,自噬相关过程可能是顶复门中另一个死亡促进途径。对寄生原生动物中PCD分子基础的详细机制研究代表了研究和药物开发的肥沃领域。
Programmed cell death (PCD) pathways remain understudied in parasitic protozoa in spite of the fact that they provide potential targets for the development of new therapy. The best understood PCD pathway in higher eukaryotes is apoptosis although emerging evidence also points to autophagy as a mediator of death in certain physiological contexts. Bioinformatic analyses coupled with biochemical and cell biologic studies suggest that parasitic protozoa possess the capacity for PCD including a primordial form of apoptosis. Recent work in Toxoplasma and emerging data from Plasmodium suggest that autophagy-related processes may serve as an additional death promoting pathway in Apicomplexa. Detailed mechanistic studies into the molecular basis for PCD in parasitic protozoa represent a fertile area for investigation and drug development.
