Helminths can adapt to environmental conditions in the host, utilising anaerobic processes like fermentation and malate dismutation to produce energy from carbohydrate. Although targeting carbohydrate metabolism is an established therapeutic strategy to combat helminth infection, questions remain over the metabolic pathways they employ as adults to survive and evade host immunity. Helminths also use amino acid, polyunsaturated fatty acid (PUFA), and cholesterol metabolism, a possible strategy favouring the production of immunomodulatory compounds that may influence survival in the host. Here, we discuss the significance of these differing metabolic pathways and whether targeting of helminth metabolic pathways may allow for the development of novel anthelmintics.
寄生虫可以适应宿主环境条件,利用厌氧过程(如发酵和苹果酸歧化)从碳水化合物中产生能量。尽管针对碳水化合物代谢是一种对抗寄生虫感染的既定治疗策略,但对于它们在成虫阶段赖以生存和逃避宿主免疫的代谢途径仍存在疑问。寄生虫还利用氨基酸、多不饱和脂肪酸(PUFA)和胆固醇代谢,这可能是一种有利于产生免疫调节化合物的策略,这些化合物可能会影响其在宿主中的生存。在这里,我们讨论了这些不同代谢途径的意义,以及是否针对寄生虫代谢途径可能为开发新型驱虫药提供可能。
