Anaphylatoxin是一个英文词汇，意思是补体活化片段相关分子。它是一种由补体活化产生的细胞因子，具有强烈的炎症介质作用，可以引起一系列的血管扩张和通透性增加，并可引起平滑肌收缩、白细胞趋化、血小板聚集等。
在英文范文方面，以下是一篇可能的示例：
标题：Anaphylatoxin and Inflammatory Response
Anaphylatoxin, a product of the complement system, plays a crucial role in the inflammatory response. When complement is activated by foreign particles or damaged cells, anaphylatoxin is released into the bloodstream, where it acts on various cells and tissues to induce a series of inflammatory reactions. These reactions include increased vascular permeability, vasodilation, and smooth muscle contraction, as well as leukocyte and platelet recruitment. Anaphylatoxin also promotes the production of additional cytokines and chemokines, further amplifying the inflammatory response. Understanding the role of anaphylatoxin in inflammatory diseases may lead to new therapeutic strategies for treating these conditions.
anaphylatoxin的意思是“过敏毒素”。在医学和免疫学中，anaphylatoxin是一类由过敏反应产生的细胞产物，特别是C型过敏反应蛋白（C-reactive protein）。它们在体内与补体系统有关，参与免疫反应和炎症过程。
以下是一篇关于anaphylatoxin的英文范文：
Anaphylatoxin C3a: An Important Mediator in the Immune Response
The immune system is a complex network of cells and proteins that work together to protect the body from harmful microorganisms. One of the key players in this system is anaphylatoxin C3a, a chemical messenger that is released during an immune response.
C3a is produced by the body’s immune cells when they are activated during an allergic or inflammatory reaction. It plays a crucial role in the inflammatory process by attracting white blood cells to the site of injury and stimulating them to release additional cytokines and other inflammatory mediators. These substances then cause further tissue damage and promote healing.
Anaphylatoxin C3a also plays a role in the activation of other immune cells, such as neutrophils and macrophages. It stimulates these cells to release additional cytokines and other inflammatory mediators, which further enhances the immune response.
In addition to its role in the inflammatory response, C3a is also involved in the activation of the complement system, a crucial part of the innate immune response. The complement system is a series of proteins that work together to kill bacteria and viruses, and it is activated by binding to anaphylatoxin C3a on immune cells.
Overall, anaphylatoxin C3a plays a key role in the immune response by promoting inflammation, activating other immune cells, and activating the complement system. Understanding its role in health and disease may lead to new therapeutic strategies for treating various immune-related conditions.
anaphylatoxin的意思是补体活化后产生的过敏毒素。
在英文范文中的用法，例如：
- Anaphylatoxin C5a is a key mediator of complement activation and a critical modulator of inflammatory responses.
- 补体活化产生的过敏毒素C5a是补体激活的关键介质，也是炎症反应的重要调节剂。
