Langerhans cells are generated by two distinct PU.1-dependent transcriptional networks. Stratum corneum defensive functions: an integrated view. 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. immune responses initiated by LCs are complex and dependent on antigenic properties of the dendritic cell (DC) lineage, they are now considered to be a specialized subset protozoan infection that is transmitted by sandflies and, in its cutaneous form, manifests as open sores or chronic non-healing ulcers. important structural protein of the stratum corneum and a major source for natural moisturizing factors. Langerhans cells are negative regulators of the anti-Leishmania response.

Islet resident macrophages are uniquely found within the endocrine tissue (islet), while nearby in the nearby acinar tissue, macrophages express a different repertoire of CD (cluster of differentiation) markers and come from a different developmental origin. Control of RelB during dendritic cell activation integrates canonical and noncanonical NF-kappaB pathways.
