Dendritic cells (DCs) are a type of immune cell that play a crucial role in the body's immune response. They act as antigen-presenting cells (APCs), which means they process antigen material and present it on their surface to T-cells, thereby initiating an immune response. DCs are found in tissues that are in contact with the external environment, such as the skin, and the inner lining of the nose, lungs, stomach, and intestines.
