exocytosis
解釋
胞吐，胞裂外排，外吐作用-
Both products are released by exocytosis.
兩種產物都由外排作用釋放出來。 -
Exocytosis is the reverse of endocytosis.
出胞作用是內容作用的逆轉。 -
Rab gtpases are involved in cell differentiation, migration, endocytosis and exocytosis, cytosolic proteins transport and regulation of the transport and fusion of vesicle. in neuron cells, rab gtpases play a crucial role in synaptic vesicle transmission and transmitter release
Rab蛋白主要通過調節囊泡（ vesicle ）的出芽（ budding ） 、運輸、錨定和融合，參與細胞的分化發育、細胞的內吞和外排、胞內蛋白的運輸、交換和定位以及神經遞質的運輸和釋放。 -
The exocytosis of milk fat may be related to its high lysolecithin content.
乳脂的外吐，可能與它溶血卵磷脂含量有關。 -
Nishio h. and colleagues find that rab3d mrna is upregulated in the course of myeloid differentiation into granulocytic pathway, which suggests that human rab3d may play a specific role in granulocytes functions, for example, exocytosis of neutrophil - specific granules or degranulation of both eosinophils and basophils
其他的研究者在實驗中也發現， rab1a 、 rabz 、 rab4 、 rabs 、 rab6 、 rab7在白血病細胞的粒系或單核系分化途徑中都有升高。可惜的是關于這方面的研究很少，也不深入。 -
The results were as follows : ( l ) the pre - incubation of pmr induced the exocytosis of the cortical granules ( cgs ) in the oocytes and reduced the quantity of the microvillus on the surface of oocytes ; ( 2 ) the matrix of cg might migrate to the surface of plasma membrane of oocytes after pmr pre - treatment. ( 3 ) incubation of zona - free hamster eggs with spermatozoa pretreated with pmr a ntiserum was associated with a dose - dependent significant reduction in the number of spermatozoa binding to the oolemma, compared with a contraband with a dose - dependent reduction of the fertilization rate and the penetration index. the results indicate that mr of human sperm plays an important role in sperm - oocyte fusion and oocyte activation
結果顯示： （ 1 ）人精子mr能夠誘發去透明帶金黃地鼠卵母細胞中皮質顆粒的胞吐，並引起卵母細胞膜表面微絨毛形態和數量發生改變； （ 2 ）皮質顆粒胞吐后，其內容物可結合到卵膜表面； （ 3 ）抗mr抗血清預處理精子可抑制精子與卵子的結合與融合，使受精率、穿透指數和結合指數下降，並均有劑量依賴性。以上結果提示，人精子mr在受精過程中起重要作用，其主要作用可能是介導精-卵膜融合併促進卵母細胞的活化。 -
In order to investigate the role of mannose receptor ( mr ) of human sperm, the zona free hamster eggs were pre - incubated with purified mr ( pmr ) isolated from motile human sperm by mannose - agarose gel affinity chromatography. the ultrastuctural alteration and cortical granule exocytosis of the eggs were then observed by transmissian electron microscope and tritc - lca immunofluorescence microscope, respectively. the mice were immunized with pmr and the antiserum was raised. after capacitation and induction of the acrosome reaction, the human spermatozoa and oocytes were incubated with the antiserum. then the sperm penetration assay was undertaken
為了進一步探討人精於mr在精卵融合中的作用，本文採用改良后的甘露糖-瓊脂糖凝膠親和層析法分離純化人精子mr ，並將提純的人精子甘露糖受體（ purifiedmannosereceptor ， pmr ）作用於去透明帶的金黃地鼠卵母細胞，運用透射電子顯微鏡技術和羅丹明偶聯的兵豆凝集素（ tritc - lca ）免疫熒光標記技術觀察pmr對卵子的影響。
