Endocytosis - Wikipedia
Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested materials. Endocytosis includes pinocytosis (cell drinking) and phagocytosis (cell eating).
胞吞作用 - 维基百科，自由的百科全书
胞吞作用 （Endocytosis）又稱 內吞作用 、 入胞作用，是 大分子 物質（如 糖類 、 脂質 、 蛋白質 等）、亞顯微顆粒（如 病毒），或大如其他細胞、其他微生物（如 凋亡 細胞、 細菌）進入細胞內部的方式。 有別於小分子物質（如 水 、 無機鹽 、 氨基酸 等）進入細胞的方式（簡單擴散或主動運輸），胞吞作用先以細胞膜凹陷的方式形成一個 囊泡 （vesicle），將欲進入細胞內部的物質包裹起來，之後囊泡脫離細胞膜進入細胞內部，而細胞膜重新組合以免出現破損，此時囊泡會一 …

细胞内吞作用或胞吞作用 (endocytosis)是细胞从胞外获取大分子和颗粒状物质的一种重要方式，它是 真核细胞 中普遍存在的一种生理现象。 胞外物质通过质膜包裹，质膜内陷并形成膜包被的囊泡，囊泡与质膜脱离进入胞内并在胞内产生一系列的生理活动和生理功能。 胞吞作用与多种生命活动有着密切关系，如免疫应答、神经递质运输、细胞信号转导、细胞和组织代谢平衡等。 近年来随着对其研究的深入，我们对胞吞作用的功能和机制有了较深入的认识。 根据胞吞作用所形成内 …
Endocytosis - The Cell - NCBI Bookshelf
Eukaryotic cells are also able to take up macromolecules and particles from the surrounding medium by a distinct process called endocytosis. In endocytosis, the material to be internalized is surrounded by an area of plasma membrane, which then buds off inside the cell to form a vesicle containing the ingested material.
Transport into the Cell from the Plasma Membrane: Endocytosis
In this process, the material to be ingested is progressively enclosed by a small portion of the plasma membrane, which first invaginates and then pinches off to form an endocytic vesicle containing the ingested substance or particle. Two main types of endocytosis are distinguished on the basis of the size of the endocytic vesicles formed.
Endocytosis – Definition, Steps, Types, Mechanism, Function, …
2024年4月7日 · Endocytosis, a fundamental cellular process, facilitates the internalization of extracellular substances, encompassing proteins, fluids, electrolytes, and various macromolecules. This mechanism is pivotal for the cell to acquire essential nutrients, regulate cellular components, and maintain homeostasis.
Mechanisms of endocytosis - PubMed
Endocytic mechanisms control the lipid and protein composition of the plasma membrane, thereby regulating how cells interact with their environments. Here, we review what is known about mammalian endocytic mechanisms, with focus on the cellular proteins that control these events.
Endocytic Pathways and Endosomal Trafficking: A Primer
Endocytosis, the process by which cells internalize macromolecules and surface proteins, was first discovered with the advancement of electron microscopy that enabled visualization of the specialized membrane domains responsible for two mechanistically and morphologically distinct pathways: clathrin-mediated endocytosis (CME) [1] and caveolae up...
Vesicle Formation and Endocytosis: Function, Machinery, …
In this review of endocytosis, we broadly discuss the structural and signaling proteins that compose the molecular machinery governing endocytic vesicle formation (budding, invagination, and fission from the membrane), with some regard for the specificity observed in …
The Cell Biology of the Endocytic System from an Evolutionary ...
Comparing the endocytic machinery of diverse organisms has provided insights into the origins and evolution of endocytic systems, as well as basic functions of modern cells. The endomembrane system mediates transport of lipids, proteins, and other molecules to the various locations in the eukaryotic cell.
