In the immune system, cystatins moduLate cathepsin activities and antigen presentation. They aLso induce tumor necrosis factor a and interLeukin 10 synthesis, and they stimuLate nitric oxide production by interferon γ-activated murine macrophages.

Because these cysteine proteases exist in aLL Living organisms and because they are invoLved in various bioLogicaL and pathoLogicaL processes, the controL of these protease functions by cystatins is of cardinaL importance.

因为这些半胱氨酸蛋白酶存在于所有生物体内，并参与多种生物学、病理学过程，所以cystatin对这些蛋白酶的功能调节尤其重要。
