Antigen-presenting cells in the skin that engulf and process foreign particles. Langerhans cells are specialized dendritic cells in the epidermis that perform phagocytosis to capture microbes and debris. They then process the antigens and migrate to lymph nodes to present them to T cells, helping to initiate the adaptive immune response. This role as immune sentinels distinguishes them from other skin cells: melanocytes make pigment, keratinocytes form the protective outer layer by producing keratin, and desmosomes are junctions that glue skin cells together. So, Langerhans cells best fit the description of immune cells that engulf foreign particles.
