Healthy cells typically attempt to kill internalized pathogens by having the entry vacuoles fuse with lysosomes , cellular structures containing enzymes that chop up proteins , lipids and dna 一般来说,健康的细胞会以溶小体与囊泡融合,将进入细胞的病原菌杀死;因为溶小体当中带有分解蛋白质、脂质及dna的酵素。
One potential drug could interfere with the proteins ' activity in a way that would force the entry vacuole to fuse with lysosomes , triggering an immune attack right after the chlamydiae invade the cell 其中一种的可能作用,在于干扰这些蛋白质的活性,迫使入侵囊泡与溶小体融合,而在披衣菌侵入细胞后,即迅速引发免疫攻击。
The place where it adds up is called the lysosome , a special vessel that contains the most powerful degradation machinery in the cell ; if something can ' t even be broken down there , it just stays there forever 堆积的地方称为溶酶体,它是一种细胞中含有最强大降解机器的特殊容器;如果某些东西甚至不能被溶酶体所降解,它就会永远堆积在那儿。
Under transmission electron microscopy , lead granules deposited in lysosome , then accumulated gradually in the apex of the cells , and finally were individually discharged into the gland lumen by apocrine secretion and excreted with the urine 在电镜下细胞内的溶酶体中沉积有大量的铅颗粒,铅通过积聚,在细胞顶端部位逐渐增多,从而出现外排现象。
It will take time to find the right enzymes in the soil microorganisms , to find the ones that work well in mammalian cells and are not toxic , to modify them so that the cell knows how to target them to the lysosome , and so on 需要时间在土壤微生物中发现需要的酶、这些酶能在哺乳动物细胞中工作得很好而又没有毒性、修饰它们使得细胞知道怎样把它们运送到溶酶体,等等。
A lot of mercury granules were found primarily in antennal gland by transmission electron microscope and mass spectrum analysis . mercury granules were found in the lysosome of the cell of antennal gland , and were transited to lumen by apocrine secretion 日本沼虾的触角腺内具有大量的汞颗粒;汞颗粒沉积在细胞内的溶酶体中,汞颗粒通过顶端分泌排出细胞并积聚在触角腺的管腔内。
The lysosome system and the other cells amongst retinular cells carry out the breakdown of microvilli . the former includes coated vesicles , lysosome , lamellar bodies and oil droplets ; and the latter include the hemocytes , proximal reflecting pigment cells and nerve glial cells 微绒毛降解过程通过自身的溶酶体系统(包括被膜小泡、溶酶体、板膜体和脂滴)和小网膜细胞之外的其它细胞(如血细胞、近端反光色素细胞和神经胶质细胞)共同完成。
Nucleoli do not emerge in this process . the number of the organelles increase until secondary spermatocyte stage . mitochondria accumulate together , merging together with lysosomes and golgi bodies at the early spermatid stage , and finally the lamellar structure is formed , which forms the acrosome at last 在精子发生过程中,线粒体、内质网和核糖体逐渐增多,其中线粒体数目在次级精母细胞阶段达到顶峰,并形成线粒体区,精细胞早期核内出现膜性泡结构,同时次级溶酶体与高尔基体大量存在,这些细胞器共同形成片层复合体,并参与顶体的形成。
We found nuclear deformation lymphocytes with increased heterochromatin and impaired thymus epithelium cells with increased lysosomes and deformation of mitochondrias . ( 4 ) effects on mouse liver of so2 challenge : so2 can cause significant liver injury . he staining showed several kinds of necrosis of liver including spot necrosis , focal necrosis and submassive necrosis infiltrated with lymphocytes , monocytes , few neutrophils and eosinophils ; tem observation showed fatty degeneration with dispersion of fatty droplets and dilation of rough endoplasmic reticulums , acid degeneration with significant hyperplasia of mitochondrias , necrosis of hepatocytes with karyorrhexis and other organelles losing their normal structure ( 4 )二氧化硫染毒对小鼠肝脏的组织学结构有明显影响,可引起肝脏点状坏死、灶状坏死甚至片状坏死,伴随不同程度的炎性细胞浸润;透射电镜观察发现二氧化硫可引起肝细胞脂肪变性、嗜酸性颗粒变和坏死,脂肪变肝细胞中可见大小不等的脂滴存在,嗜酸性颗粒变肝细胞中可见线粒体明显增生,坏死肝细胞可见细胞核结构破坏,细胞器减少,细胞膜不完整。
Lots of copper granules were primarily deposited in hepatopancreas tubules and r cell of the hepatopancreas , and accumulated copper granules were distributed in haemocyte space . under transmission electron microscopy , copper granules were primarily deposited in the lysosome of hepatopancreas cells , and a little amount of copper granules was absorbed in smooth surfaced endoplasmic reticulum . the copper granules were excreted to the lumen by apocrine secretion 大量铜颗粒分布在肝胰脏的肝小管和r细胞中,在血腔中也有铜颗粒的分布;电镜观察发现铜主要分布在细胞内的溶酶体中,少量颗粒吸附在滑面内质网上;这些铜颗粒通过积聚,在细胞顶端逐渐增多,从而出现外排现象。
an organelle found in the cytoplasm of most cells (especially in leukocytes and liver and kidney cells)
百科解释
Lysosomes are cellular organelles that contain acid hydrolase enzymes that break down waste materials and cellular debris. They can be described as the stomach of the cell.
