Answer Choices:
Dendritic cells
🔴 Dendritic cells (Langerhans cells) in the epidermis serve an immunological role by acting as antigen-presenting cells.
🔴 They capture and process microbial antigens that breach the skin barrier.
🔴 Once activated, they migrate to lymph nodes to stimulate T-cell responses.
🔴 This makes them essential for cutaneous immunity and defense against infections.
🔴 Other cells like keratinocytes, melanocytes, and Merkel cells have structural, pigmentary, or sensory roles but are not primary immune cells.
