Dendritic cells
Dendritic cells are a type of immune cell that act as crucial messengers between the innate and adaptive immune systems. They are found in tissues and are responsible for capturing, processing, and presenting foreign substances, like viruses or bacteria, to T cells, which then help orchestrate an immune response. Think of them as "scouts" that identify threats and alert other immune cells. By educating T cells about these invaders, dendritic cells play a vital role in initiating and shaping the body’s defense against infections and diseases.

Dendritic cells are a type of immune cell that play a crucial role in the body's defense system. They act as sentinels, constantly monitoring for signs of infection or foreign invaders. When they encounter pathogens, such as viruses or bacteria, dendritic cells capture and process these threats. They then travel to the lymph nodes, where they present pieces of the pathogens to other immune cells, helping to activate and orchestrate a stronger immune response. Essentially, dendritic cells are like messengers, educating the immune system about what it needs to fight off infections effectively.
