这关键区别在顺行和逆行运输之间是顺行传输将生理材料移向突触前末端,而逆行运输将生理材料从外围移回细胞体。
轴突运输是一种生理过程,可将神经体中合成的蛋白质和其他物质传递到神经末端。细胞骨架。简而言之,这是涉及细胞体和轴突末端之间物质转移的过程神经元。轴突are capable of bidirectional transport. Based on the direction of the material flow, there are two categories of axonal transport: anterograde and retrograde axonal transport. In anterograde transport, materials are transported towards the presynaptic terminals while in retrograde transport, materials are transported from the periphery towards the cell body.

什么是顺行运输?
Anterograde transport is one of the two types of axonal transport. In anterograde transport, materials are transported towards the presynaptic terminals. Through this process, nutrients, organelles, and other molecules are transported from the soma (cell body) to the distal axon. Anterograde transport is facilitated by cytoplasmic motors kinesins. Anterograde transport is important since it provides newly synthesized components such as membrane-associated enzymes, neurotransmitters, neuropeptides and membrane lipids, which are essential for neuronal membrane function and maintenance.
什么是逆行运输?
Retrograde transport is the process by which physiological materials are transported back to the cell body (soma) from the periphery (axon). This process allows the returning of membrane molecules to the cell body for degradation by acid hydrolases present in lysosomes.
材料将被运送到溶酶体n the cell body are mainly transported via retrograde transport. It is also an important pathway for some neurotropic viruses to invade the central nervous system. Retrograde transport is facilitated by cytoplasmic motors dyneins. Dynein moves toward the minus end of the microtubule, which is oriented toward the cell body.
顺行传输和逆行运输之间有什么相似之处?
- 顺行和逆行运输是轴突运输的两类。
- 这些过程将材料从躯体转移到轴突和从轴突到躯体。
- 细胞质电动机促进了这些过程。
顺行传输和逆行运输有什么区别?
顺行传输是将生理材料从细胞体运输到轴突的过程,而逆行运输是将生理材料从轴突传输到细胞体的过程。因此,这是顺行传输和逆行运输之间的关键区别。此外,运动动力蛋白促进了顺行传输,而细胞质运动蛋白则有助于逆行转运。
此外,顺行传输和逆行运输之间的另一个区别是,诸如膜相关酶,神经递质,神经肽和神经肽和膜脂质等材料是通过顺序转运运输的,而应通过逆转运输运输到细胞体中的溶酶体。
以下是顺行传输和逆行运输之间差异的汇总表。
摘要 - 顺行与逆行运输
轴突运输是双向的。基于方向,可以是顺行传输或逆行运输。顺行传输涉及将材料从SOMA运输到远端轴突。相比之下,逆行运输涉及从远端区域运输材料到SOMA。因此,这是顺行传输和逆行运输之间的关键区别。运动动力蛋白参与顺行传输。运动动蛋白参与逆行运输。
