[The Langerhans cell. Recent immunologic achievements]
1Service de Dermatologie, Hôpital Michel Levy, Marseille.
Abstract:
The epidermal Langerhans cells has been keeping, most of its secrets for about a hundred years since its first description in 1868. Its characterization in electron microscopy by Birbeck and then the use of histoenzymology (ATPase) and monoclonal antibodies (against HLA-DR, T6, LCA, C3b...) brought a new great interest on its study. The Langerhans cell must play an important immunologic role in the epidermis because of its responsibility in the antigenic information of the lymphocytes; in this way it may represent the specific epidermal differentiation of the monocyte-macrophage cell type, which are all bone-marrow derived cells. The epidermal Langerhans cell is one of the most important links in the elicitation of contact dermatitis. Recent trends about its metabolism, antigens and functions are reviewed and discussed.

Cell-mediated Immune Responses
Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Antigens Involved in Adaptive Immunity
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
