Which immune cells in the skin protect against infection?

In the skin, immune protection is provided by specialized cells that reside in the epidermis. Langerhans cells act as resident antigen-presenting immune cells; they patrol the skin, capture and process microbes, and then migrate to lymph nodes to present antigens to T cells, helping to kick-start the body's adaptive immune response against infections. This makes them the primary immune defender among the options listed. Excretion isn’t a cell; it’s a process related to removing waste. Melanocytes produce melanin, the pigment that gives skin its color and helps shield against UV radiation, not primarily immune defense. Adipocytes store fat in subcutaneous tissue and provide energy and insulation, not immune protection.
