To investigate the response of Langerhans cells to tumor growth, we examined the appearance and number of ATPase+ and Ia+ dendritic cells in the epidermis covering subcutaneous tumors. Mice were injected with cells from syngeneic UVB- and PUVA-induced tumors and a melanoma, and the overlying skin was examined at various times during progressive tumor growth. An increase in the number of ATPase+ and Ia+ dendritic cells was observed in skin over all three tumor types. Morphologic alterations in the cells were also noted, including a decrease in dendricity. These changes were apparent only in skin directly over growing tumor masses; contralateral and perilesional skin was unaffected. Injection of nontumorigenic cells and implantation of silicon did not induce changes in Langerhans cells. Regression of highly antigenic tumor cells and tumor regression in immunized mice were not accompanied by detectable alterations in Langerhans cells, whereas changes in Langerhans cells were apparent during tumor growth in nude mice. These results demonstrate that changes in the number and morphology of Langerhans cells occur in response to tumor growth but that the changes are not dependent on immunologic or inflammatory responses.

UI	MeSH Term	Description	Entries
D007801	Langerhans Cells	Recirculating, dendritic, antigen-presenting cells containing characteristic racket-shaped granules (Birbeck granules). They are found principally in the stratum spinosum of the EPIDERMIS and are rich in Class II MAJOR HISTOCOMPATIBILITY COMPLEX molecules. Langerhans cells were the first dendritic cell to be described and have been a model of study for other dendritic cells (DCs), especially other migrating DCs such as dermal DCs and INTERSTITIAL DENDRITIC CELLS.

D000251	Adenosine Triphosphatases	A group of enzymes which catalyze the hydrolysis of ATP. The hydrolysis reaction is usually coupled with another function such as transporting Ca(2+) across a membrane. These enzymes may be dependent on Ca(2+), Mg(2+), anions, H+, or DNA.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000949	Histocompatibility Antigens Class II	Large, transmembrane, non-covalently linked glycoproteins (alpha and beta). Both chains can be polymorphic although there is more structural variation in the beta chains. The class II antigens in humans are called HLA-D ANTIGENS and are coded by a gene on chromosome 6. In mice, two genes named IA and IE on chromosome 17 code for the H-2 antigens. The antigens are found on B-lymphocytes, macrophages, epidermal cells, and sperm and are thought to mediate the competence of and cellular cooperation in the immune response. The term IA antigens used to refer only to the proteins encoded by the IA genes in the mouse, but is now used as a generic term for any class II histocompatibility antigen.
