應用
在一项研究中，使用人糜酶来评估三七花提取物对心脏重构中TGFβ/ Smad信号转导途径的影响。 人糜酶也已被用于一项研究中，以研究链脲佐菌素处理的人糜酶转基因小鼠的血糖水平和存活率。
胸苷酶与血管紧张素II的产生和大内皮素的裂解有关。研究表明它可能与血管增生、心肌梗塞和皮炎有关。
生化／生理作用
该酶可迅速将血管紧张素 I 转化为血管紧张素 II。酶活性的最适 pH 值为 7.5 ~ 9.0。大豆胰蛋白酶抑制剂、苯甲基磺酰氟和糜蛋白酶抑制剂可抑制酶的活性。
物理性質
糜蛋白酶是一种主要存在于肥大细胞的组织蛋白酶G样S1丝氨酸蛋白酶。它的分子量约为30 kDa，但在SDS-PAGE上的表观分子量约为37 kDa。

During infection and tissue damage, virulence factors and alarmins are pro-inflammatory and induce activation of various immune cells including macrophages and mast cells (MCs). Activated MCs instantly release preformed inflammatory mediators, including several proteases. The chymase mouse mast cell protease

Tumor cells are surrounded by infiltrating inflammatory cells, such as lymphocytes, neutrophils, macrophages, and mast cells. A body of evidence indicates that mast cells are associated with various types of tumors. Although role of mast cells can be directly related

Nutritional stimulation of the cholecystokinin-1 receptor (CCK-1R) and nicotinic acetylcholine receptor (nAChR)-mediated vagal reflex was shown to reduce inflammation and preserve intestinal integrity. Mast cells are important early effectors of the innate immune response; therefore modulation of mucosal mast cells
