dendritic

dendritic的音标是[dɪˈnɪstɪk]，基本翻译是树突的，速记技巧是谐音记忆：“地尼斯特”（谐音：地上的树枝）。

Dendritic这个词源于希腊语词根dendron，意思是“树”或“树状物”。这个词在英语中主要用作形容词和名词，表示树枝状的或分枝的。

变化形式：词形主要为复数形式，如dendrites。

相关单词：

1. Dendrite：树枝、树枝状物；神经元树突。树突是神经元的一部分，呈树枝状，负责接收来自其他神经元的电信号。

2. Dendriticity：树枝状结构；分枝性。这个词用来描述具有树枝状特性的结构或系统。

3. Dendritic branching：树枝状分支；分枝生长。描述树枝或分枝的形状和生长方式。

4. Dendritic cell：树突细胞；抗原呈递细胞。树突细胞是免疫系统中重要的一类细胞，能够捕获并处理抗原，然后将这些信息传递给其他免疫细胞。

5. Dendritic spine：树突棘；神经元突触小体。树突棘是神经元树突上的一种结构，与突触相连，参与神经信号的传递。

6. dendrology：树木学；树志学。这个学科研究各种树木的形态、生长和分布，以及它们在生态系统中的作用。

7. dendrochronology：树木年轮学；年轮考古学。这个学科研究树木年轮的周期性变化，以此来推断气候变化、地质事件等历史信息。

8. dendrogram：树状图；分支图。这是一种用于表示系统或组织结构的图表，通常以树状的形式展示各个组成部分及其之间的层次关系。

9. dendritic map：树枝状图；树突图。这个词用来描述神经元内部的结构图，显示了树突和与其相连的突触的位置和数量。

10. dendritic spine modulation：树突棘调节；神经元突触可塑性。这个词描述了如何通过改变树突棘的形态或数量来影响神经元的信号传递和行为。

Dendritic Cells: Guardians of the Immune System

Dendritic cells are a type of immune cell that plays a crucial role in defending the body against foreign invaders. These sentinels of the immune system patrol the body, detecting potential threats and alerting other immune cells to their presence.

Through their unique ability to capture and present antigens to T cells, dendritic cells initiate and drive the adaptive immune response. They also play a role in immune regulation, helping to maintain balance in the body’s response to foreign invaders.

Dendritic cells can be found in various tissues throughout the body, including the skin, gut, lungs, and lymph nodes. Their location allows them to quickly respond to threats in different parts of the body, ensuring that the immune system is effective against a wide range of infections and diseases.

Despite their crucial role in defending the body, dendritic cells can also have a negative impact in certain conditions, such as autoimmunity and allergies. Understanding their function and regulation is essential for developing effective treatments and preventing diseases.
