dendritic的音標是[d??n?st?k]，基本翻譯是樹突的，速記技巧是諧音記憶：“地尼斯特”（諧音：地上的樹枝）。

Dendritic這個詞源于希臘語詞根dendron，意思是“樹”或“樹狀物”。這個詞在英語中主要用作形容詞和名詞，表示樹枝狀的或分枝的。

變化形式：詞形主要為復(fù)數(shù)形式，如dendrites。

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.
