2023年7月26日 · Cystatin C is a protein produced by the cells in your body. When kidneys work well, they keep the level of cystatin C in your blood just right. If the level of cystatin C in your blood is too high, it may mean your kidneys are not working well.

胱抑素C (Cystatin C，Cys C)，又名γ2痕迹碱性蛋白或后 γ球蛋白，是 半胱氨酸蛋白酶抑制剂 蛋白质 中的一种。 编码Cys C的基因属于 管家基因，能在所有的 有核细胞 内以恒定速度持续转录与表达，无 组织特异性，故Cys C可在体内以恒定速度产生，并存在于各种体液之中，尤以 脑脊液 和 精浆 中含量为高，尿液中最低，不受年龄、性别、体重、炎症等因素影响，（研究表明Cys C自1岁后到60岁前在血液中浓度恒定）。 其分子量小（13KD）， 生理条件 下带 正电荷，能自 …

2021年1月15日 · Cystatin C can be used as a replacement for blood creatinine for the assessment of kidney function. It has several advantages over creatinine: Its levels don’t depend on muscle mass, physical activity, or protein intake.

Cystatin C or cystatin 3 (formerly gamma trace, post-gamma-globulin, or neuroendocrine basic polypeptide), [5] a protein encoded by the CST3 gene, is mainly used as a biomarker of kidney function. Recently, it has been studied for its role in predicting new-onset or deteriorating cardiovascular disease .

Serum cystatin C is an earlier and more accurate biomarker of GFR than creatinine in many patient populations. Cystatin C is independently associated with cardiovascular disease, end stage renal disease, and all-cause mortality.

2024年8月28日 · What is the cystatin C test? The cystatin C test is a type of blood test to see how well your kidneys are working. Cystatin C is a protein made by cells in your body. Here is how this works: Your cells make cystatin C and release it into your blood at a steady pace. Then, your kidneys filter out cystatin C to keep it at a normal level.

胱抑素C(cystatin C、cystatin 3、gamma trace、血清胱抑素C、半胱氨酸蛋白酶抑制劑、胱蛋白、後γ-球蛋白，或神經內分泌基本多肽)， [2] 是由CST3基因編碼的一種蛋白質，其分子量小(13000)由體內有核細胞恆定產生，能自由通過(濾過)腎小球，且腎小管上皮細胞不分泌亦 ...

血清胱抑素C（Cystatin C，简称CysC）亦称半胱氨酸蛋白酶抑制剂C，是一种由120个氨基酸组成，分子量为13kDa的低分子量、碱性非糖化蛋白质。 CysC基因在包括肾、肝、胰、肠、胃、肺及胎盘等所有组织中持续地转录和表达。

2022年8月18日 · 胱抑素(cystatin c)是一种半胱氨酸蛋白酶抑制剂，也被称为γ-微量蛋白及γ-后球蛋白，广泛存在于各种组织的有核细胞和体液中,是一种低分子量、碱性非糖化蛋白质，分子量为13.3KD，由122个氨基酸残基组成,可由机体所有有核细胞产生，产生率恒定。

胱抑素 C，又称半胱氨酸蛋白酶抑制剂 C（Cystatin C，Cys C），编码基因属于管家基因，能在所有的有核细胞内以恒定速度持续转录与表达，无组织特异性，故 Cys C 可在体内以恒定速度产生，并存在于各种体液之中，不受年龄、性别、体重、炎症等因素影响，胱 ...
