In adults, pulmonary involvement with Langerhans’ cell histiocytosis usually occurs as a single-system disease and is characterised by focal Langerhans’ cell granulomas infiltrating and destroying distal bronchioles. Langerhans cell histiocytosis is an abnormal clonal proliferation of Langerhans cells, abnormal cells deriving from bone marrow and capable of migrating from skin to lymph nodes. Here, we review some aspects of LC biology, emphasizing those areas where LC are or may turn out to be special. Adult pulmonary Langerhans’ cell histiocytosis is a rare disorder of unknown aetiology that occurs predominantly in young smokers, with an incidence peak at 20–40 yrs of age. 1983 Nov 1;158(5):1522-36. doi: 10.1084/jem.158.5.1522. animal models of allergic contact dermatitis in which haptens are sensitized through the skin.

On the basis of their similarity to these other dendritic cells, we believe Langerhans cells may function in antigen presentation, lymphokine production, provision of a microenvironment for T lymphocytes, and prostaglandin secretion. antibodies that upon binding neutralize the biological function of their antigen. properties. In contrast to other DCs, LCs arise from hematopoietic precursors that seed the skin before birth. tissue macrophages and similar to DCs, they homeostatically migrate to lymph nodes Elicit immune responses only in the bound form.
