What is a "dendritic cell"?

A dendritic cell is an antigen-presenting cell that plays a crucial role in the immune system by capturing and presenting antigens to other immune cells, thus initiating and coordinating immune responses in the human body. Dendritic cells act as sentinels, patrolling various tissues, and are responsible for activating T cells and shaping both innate and adaptive immune responses. They are known for their unique ability to bridge the innate and adaptive immune systems, making them essential for effective immune defense against pathogens and the development of immunological memory.

Examples

1. The circled type of cell in the lining of the wall are these dendritic cells.

2. Macrophages and dendritic cells are pretty much similar in this respect.

3. So I have this dendritic cell here.

4. Dendritic cells tend to inhabit the lymph nodes.
