What is the function of dendritic cells in inflammation?

• A. To transport oxygen to injured tissues
• B. To capture and present antigens to T cells
• C. To release inflammatory mediators
• D. To facilitate the formation of scar tissue

Answer: (B)

Dendritic cells play a crucial role in the immune response, particularly in the context of inflammation. Their primary function is to capture, process, and present antigens to T cells, which is key for initiating adaptive immune responses. When tissue injury or infection occurs, dendritic cells migrate from the site of inflammation to the lymph nodes, where they present the processed antigens to T cells. This interaction is essential for T cell activation, which leads to a more specific immune response aimed at eliminating pathogens or damaged cells. While other cells are responsible for functions such as transporting oxygen, releasing inflammatory mediators, or facilitating scar tissue formation, it is primarily the antigen presentation by dendritic cells that bridges the innate and adaptive immune responses during inflammation. This ensures that the body can effectively recognize and respond to specific threats, thus playing a vital role in the inflammatory process.
