antigenic

antigenic的音标为[ˌæntɪdʒɪ"enɪk] ，基本翻译为“抗原的”，速记技巧为“抗原=抗(antibody)免疫(immune)的”。

Antigenic:

1. 词源: 该词源于希腊语“anti” (反对) 和“genos” (种类) ，因此“antigen”意为“对抗原”。

变化形式: 无变化形式。

相关单词:

1. Antigenic determinant: (抗原决定基) - 这是抗原分子上决定其免疫特性的特定结构。

2. Antigen-antibody reaction: (抗原抗体反应) - 这是免疫系统中常见的一种反应，当抗原与抗体结合时会形成免疫复合物，可能导致组织损伤。

3. Antigenic shift: (抗原性转变) - 指由于某些因素导致机体抗原性发生改变的现象。

4. Antigenic diversity: (抗原多样性) - 指抗原分子种类的多样性，有助于机体识别不同的抗原并产生特异性免疫反应。

5. Antigenic mimicry: (抗原模拟) - 指一种现象，即一种抗原分子可能与其相似物在结构上相似，导致机体产生错误的免疫反应。

6. Antigen-presenting cell (APC): (抗原呈递细胞) - 这类细胞可将抗原呈递给T细胞，使其识别并引发免疫反应。

7. Antigen capture assay: (抗原捕获试验) - 一种用于检测特定抗原的实验室技术。

8. Antigen-specific T cell response: (抗原特异性T细胞反应) - 指T细胞针对特定抗原产生的免疫反应。

9. Antigen-antibody complex: (抗原抗体复合物) - 指抗原与抗体结合形成的复合物，通常在免疫反应中形成。

10. Antigen-binding site: (抗原结合位点) - 指抗体或受体蛋白上与抗原结合的特定区域，有助于识别和引发免疫反应。

antigenic常用短语：

1. antigenic difference 抗原性差异

2. antigenic determinant 抗原决定基

3. antigenic formula 抗原式

4. antigenic site 抗原位点

5. antigenic specificity 抗原特异性

6. antigenic structure 抗原性结构

7. antigenic variation 抗原性变化

例句：

2. The two proteins have different antigenic properties.

3. The immune system responds to antigens in a unique way.

4. The tumor cells express antigens that can be recognized by the immune system.

5. Antigenic variation is a mechanism used by viruses to evade the immune response.

6. The vaccine must be updated regularly to include new antigens that arise in the disease.

7. Understanding antigenic variation is crucial for effective vaccine design.

Antigens and Immunity

Antigens are proteins or other substances that trigger an immune response when they are recognized by the immune system. Antigens are important in immunity because they allow the body to recognize and fight off foreign invaders, such as viruses and bacteria. However, antigens can also vary between individuals, leading to antigenic variation, a mechanism used by viruses to evade the immune response and replicate more efficiently. Understanding antigenic variation is crucial for effective vaccine design and development, as it allows for the identification of antigens that are specific to a given pathogen and can therefore elicit a strong and lasting immune response. In addition, antigens can also be used for diagnosis and monitoring of diseases, allowing for early detection and treatment of infections. Therefore, antigens play an essential role in immunity and disease management.
