Which cells are known for phagocytosis and immune defense in the skin?

Macrophages are the cells known for phagocytosis and immune defense in the skin. They actively engulf bacteria, dead cells, and debris, acting as frontline defenders. They also coordinate the immune response by releasing cytokines and presenting antigens to T cells, helping to activate the adaptive immune system. In the skin, these macrophages reside in the dermis and play a key role in surveillance, inflammation, and wound healing. While there are other immune-related cells in the skin, such as antigen-presenting Langerhans cells, the primary phagocytic immune defense comes from macrophages. The other options aren’t phagocytes or primary defenders in skin: nerve endings sense stimuli, sweat glands secrete sweat, and plasma cells produce antibodies.
