Abstract

Autophagy is a self-destructing mechanism of cell via lysosomal degradation, which helps to degrade/destroy hazardous substances, proteins, degenerating organelles and recycling nutrients. It plays an important role is cellular homeostasis and regulates internal environment of cell, moreover, when needed causes non-apoptotic programmed death of cell. Autophagy has been observed as one of the major factors in parasite clearance in leishmaniasis. Being an intra-cellular pathogen, the cell mediated response is the only alternative for adaptive immunity against Leishmania in host. Pro-inflammatory cytokines IL12 and TNFα generate Th2 response which helps in active phagocytosis of parasite whereas an anti-inflammatory cytokine like IL10 mediate parasite promotion by blocking autophagic pathways and inhibiting phagocytic actions. In the present chapter, through systems biology approach, we are trying to decipher the role of pro-inflammatory and anti-inflammatory cytokine in autophagy during leishmanial infection. TLR2/6 mediated signaling stimulated by LPG produces many pro-inflammatory cytokines like IL12, TNFα and IL6 etc. Among them TNFα, causes the activation of PI3P through a series of events, which results in activation of autophagic machinery, whereas, IL10 through ATG9 and mTOR activation, inhibits autophagy. The mathematical modeling of these pathways shows that, ATG9-PI3P act as a negative feedback loop in autophagic machinery of leishmaniasis.

摘要

自噬是细胞通过溶酶体降解的一种自我毁灭机制,有助于降解/破坏有害物质、蛋白质、变性细胞器和回收营养物质。它在细胞内稳态中起着重要作用,并调节细胞的内部环境,此外,在需要时会导致细胞非凋亡程序性死亡。自噬已被观察到是利什曼病中寄生虫清除的主要因素之一。作为一种细胞内寄生虫,细胞介导的反应是宿主对利什曼原虫适应性免疫的唯一替代方法。促炎细胞因子 IL12 和 TNFα 产生 Th2 反应,有助于寄生虫的主动吞噬,而抗炎细胞因子如 IL10 通过阻断自噬途径和抑制吞噬作用来促进寄生虫。在本章中,我们通过系统生物学方法,试图解码促炎和抗炎细胞因子在利什曼原虫感染期间自噬中的作用。LPG 介导的 TLR2/6 信号转导会产生许多促炎细胞因子,如 IL12、TNFα 和 IL6 等。其中 TNFα 通过一系列事件激活 PI3P,从而激活自噬机制,而 IL10 通过 ATG9 和 mTOR 激活来抑制自噬。这些途径的数学建模表明,ATG9-PI3P 在利什曼病的自噬机制中充当负反馈回路。
