Chagas cardiomyopathy is caused by infection with flagellated protozoan Trypanosoma cruzi. In patients, there is a fine balance between control of the replication and the intensity of the inflammatory response so that the host is unable to eliminate the parasite resulting in the parasite persisting as a lifelong infection in most individuals. However, the parasite persists in such a way that it causes no or little disease. This chapter reviews our understanding of many of the mediators of inflammation and cells which are involved in the inflammatory response of mammals to T. cruzi infection. Particular emphasis is given to the role of chemokines, endothelin and lipid mediators. Understanding the full range of mediators and cells present and how they interact with each other in Chagas disease may shed light on how we modulate disease pathogenesis and define new approaches to treat or prevent the disease.
克氏锥虫感染引起的恰加斯心肌病。在患者中,寄生虫的复制和炎症反应的强度之间存在着微妙的平衡,使得宿主无法清除寄生虫,从而导致寄生虫在大多数个体中持续存在为终身感染。然而,寄生虫以这样一种方式存在,它不会引起或很少引起疾病。本章回顾了我们对许多炎症介质和细胞的理解,这些介质和细胞参与了哺乳动物对 T. cruzi 感染的炎症反应。特别强调趋化因子、内皮素和脂质介质的作用。了解恰加斯病中存在的各种介质和细胞及其相互作用的方式,可能有助于阐明我们如何调节疾病发病机制,并为治疗或预防疾病提供新的方法。
