在哺乳动物中,半胱氨酸蛋白酶对于先天性和适应性免疫反应的诱导和发展至关重要。这些蛋白酶在抗原和病原体识别和消除、信号处理和细胞稳态中发挥作用。许多病原体还分泌半胱氨酸蛋白酶,这些蛋白酶通常作用于与哺乳动物蛋白酶相同的靶蛋白,从而可以调节宿主免疫从初始识别到效应机制。病原体衍生的蛋白酶包括非特异性蛋白酶,这些蛋白酶可降解参与免疫反应的多种蛋白质,而酶的作用模式非常特异。在这里,我们概述了病原体衍生的半胱氨酸蛋白酶的最新知识,这些蛋白酶通过改变哺乳动物免疫系统中关键受体或途径的正常功能来调节免疫反应。
In mammals, cysteine proteases are essential for the induction and development of both innate and adaptive immune responses. These proteases play a role in antigen-and pathogen-recognition and elimination, signal processing and cell homeostasis. Many pathogens also secrete cysteine proteases that often act on the same target proteins as the mammalian proteases and thereby can modulate host immunity from initial recognition to effector mechanisms. Pathogen-derived proteases range from nonspecific proteases that degrade multiple proteins involved in the immune response to enzymes that are very specific in their mode of action. Here, we overview current knowledge of pathogen-derived cysteine proteases that modulate immune responses by altering the normal function of key receptors or pathways in the mammalian immune system.
