Released by activated macrophage and natural killer cells , it is a potent immuno - modulator which mediates a wide range of immune and inflammatory responses including the activation of b and t cells 为细胞活素之一,由多种免疫细胞于感染、伤害或与抗原反应时产生,可用于
Each time the tests were administered , blood samples were collected to assess natural killer cell activity and number of circulating lymphocyte subsets , indicators of immune system function 每次的测试都要采取受试者血样,用于评价天然杀伤性细胞的活性和循环性淋巴细胞各亚型细胞的数量,以此反映免疫系统的功能。
Traditional nutritional protein markers ( albumin , transferrin and prealbumin ) , immunoglobulin , t - lym - phocyte subsets , pha - stimulated lymphocyte proliferation , natural killer cell activity and nitrogen balance were measured before and after nutritional support 结果较之肠外营养,肠内营养组营养前后前白蛋白变化明显,淋巴细胞增殖率增加显著。
< wp = 8 > il - 12 is an effective adjuvant that can initiate protective immune response . it regulates specific and nonspecific immune response by activating natural killer cells and cytotoxic t lymphocytes Il - 12是启动保护性细胞免疫的有效佐剂,在调节机体非特异性和特异性免疫方面具有重要作用,其调节方式主要通过刺激nk细胞和细胞毒淋巴细胞来完成。
Porcine il - 12 ( pil - 12 ) , also termed as natural killer cell stimulatory factor ( nksf ) and cytotoxic lymphocyte maturation factor ( clmf ) , can induce some cytokines , particularly ifn - , from t and nk cells , as well as enhance the cytotoxic activity of these cells . its most critical role may be to initiate the development of cell - mediated immunity by promoting the differentiation of th1 cells from naive t cells 白细胞介素- 12 ( il - 12 )又名nk细胞刺激因子( nksf )或细胞毒淋巴细胞成熟因子( clmf ) ,能诱导t细胞和nk细胞产生ifn - ,并增强其细胞毒活性,它的关键作用是能诱导th0细胞分化为th1细胞以激发细胞免疫进程。
