Final answer:
True, Langerhans cells are specialized dendritic cells found in the stratum spinosum of the skin, acting as macrophages and antigen-presenting cells in the immune system.
Step-by-step explanation:
The statement is true; Langerhans cells are indeed specialized dendritic cells located in the epidermis, particularly in the stratum spinosum layer. These cells function as macrophages and are part of the immune system. They have the ability to detect and fight pathogens that enter through the skin. Moreover, Langerhans cells are known for their role as antigen-presenting cells that trigger adaptive immune responses, which is crucial for the body's defense mechanisms against various threats.
