Lines of langerhans face
NettetEpidermal Langerhans cells use their dendrites (arm-like projections) to survey the environment, especially in the stratum corneum. The Langerhans cells bind pathogens to their TLRs, travel to draining lymph nodes, and present antigens to naïve lymphocytes. NettetFour major groups of linear patterns can be distinguished: Langer lines, dermatomes, Blaschko lines and exogenous patterns. Langer lines run in the direction of the underlying collagen fibers (least skin tension) and play an important diagnostic role for some exanthematous skin diseases.
