| 2. | The inhibitory effect of hydrocortisone on the chemotactic migration of human leukocytes
氢化可的松对人白细胞趣化移动的抑制 |
| 3. | Cf chemotactic factor
趋化因子 |
| 4. | Chemotaxis ( chemotactic movement ) a txis in response to a chemical concentration gradient
趋化现象：一种对化学浓度梯度的趋化反应。 |
| 5. | At very high doses of radiation , neutrophils failed to respond significantly to chemotactic stimuli
很高辐射剂量时，中性粒细胞对趋化刺激物无明显反应。 |
| 6. | Motile organisms may also be negatively chemotactic , swimming away from concentrations of toxic chemicals
可以游动的生物体也有负向的趋化现象，总是远离有害的化学物质。 |
| 7. | Effects of urokinase - type plasminogen activator receptor on sperm chemotactic response induced by urokinase - type plasminogen activator in mice
尿激酶受体在尿激酶诱导小鼠精子趋化运动中的作用 |
| 8. | The spermatozoids of primitive plants are often positively chemotactic , swimming toward the female organs in response to a chemical secreted by the latter
较原始的植物的游动精子有正向的趋化现象，总是游向由雌性器官所分泌的物质。 |
| 9. | Interestingly , inhibition of p38 mapk activation ( but not erk activation ) by its inhibitors or by expression of a dominant negative mutant of p38 mapk could effectively block the chemotactic effect of ( - arrestin2
P38mapk上游激酶ask1的显性失活突变体也可以阻断- arrestin2对趋化的增强作用。这说明是p38mapk而不是erk信号通路与- arrestin2对趋化的增强作用相关。 |
| 10. | Chemotaxis mediated by chemokine receptors , such as cxcr4 , play a key role in lymphocyte homing and hematopoiesis as well as in breast cancer metastasis . we have previously demonstrated that ? - arrestin2 functions to attenuate cxcr4 - meidated g protein activation and to enhance cxcr4 internalization . here we further show that expression of ( - arrestin2 in both hela and hek293 cells significantly enhanced the chemotactic efficacy of stromal - cell derived factor 1 ( ( sdf - 1 ( ) , the specific agonist of cxcr4
- arrestin2是趋化因子受体的一种重要的调节蛋白，本研究工作发现在hek - 293或hela细胞中升高- arrestin2的表达水平会显著增强cxcr4介导的趋化作用，反之当- arrestin2的表达被它的反义核苷酸或rnai所抑制， cxcr4介导的趋化作用则被明显抑制。 |
