Chemotaxis ( chemotactic movement ) a txis in response to a chemical concentration gradient
趨化現象：一種對化學濃度梯度的趨化反應。 -
At very high doses of radiation, neutrophils failed to respond significantly to chemotactic stimuli
很高輻射劑量時，中性粒細胞對趨化刺激物無明顯反應。 -
Motile organisms may also be negatively chemotactic, swimming away from concentrations of toxic chemicals
可以游動的生物體也有負向的趨化現象，總是遠離有害的化學物質。 -
Effects of urokinase - type plasminogen activator receptor on sperm chemotactic response induced by urokinase - type plasminogen activator in mice
尿激酶受體在尿激酶誘導小鼠精子趨化運動中的作用 -
The spermatozoids of primitive plants are often positively chemotactic, swimming toward the female organs in response to a chemical secreted by the latter
較原始的植物的游動精子有正向的趨化現象，總是游向由雌性器官所分泌的物質。 -
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的顯性失活突變體也可以阻斷- arrestin2對趨化的增強作用。這說明是p38mapk而不是erk信號通路與- arrestin2對趨化的增強作用相關。 -
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是趨化因子受體的一種重要的調節蛋白，本研究工作發現在hek - 293或hela細胞中升高- arrestin2的表達水平會顯著增強cxcr4介導的趨化作用，反之當- arrestin2的表達被它的反義核苷酸或rnai所抑制， cxcr4介導的趨化作用則被明顯抑制。
