Langerhans Cells in Skin Lesions of Leprosy
Background: Langerhans cells are important in the pathogenesis of leprosy. A recent study reported that these cells were almost absent in the epidermis overlying lepromatous lesions. Objective: To investigate a possible relationship between the number of Langerhans cells and the histopathologic spectrum of lesions in patients with leprosy. Methods: An immunohistochemical staining for S100 prot...

متن کاملChanges of Langerhans cells during skin ageing
INTRODUCTION During the process of skin ageing, changes occur in all skin layers and all cells, including the Langerhans cells. AIM To assess whether any quantitative difference in the number of CD1a+ LC cells/mm2 and HLA-DR+ LC cells/mm2 as well as in their morphological features can be observed during the course of different types of skin ageing. MATERIAL AND METHODS The study was conduct...
متن کاملAmerican tegumentary leishmaniasis: Langerhans cells in Montenegro skin test.
This work analyzed the histopathology and epidermal Langerhans cells (LC) of Montenegro skin test (MST) in patients with American tegumentary leishmaniasis (ATL) in order to in situ characterize and compare the immunological reaction of the two major clinical forms of ATL, localized cutaneous leishmaniasis (LCL) and mucocutaneous leishmaniasis (MCL). MST histopathology of both LCL and MCL showe...
متن کاملEpidermal Langerhans cells tune skin reactivity to contact allergens.
Allergic contact dermatitis is a common disorder that has fascinated dermatologists and immunologists for decades. Extensive studies of contact sensitivity reactions in mice established a mechanistic paradigm that has been revisited in recent years, and the involvement of Langerhans cells (LCs), a population of epidermal dendritic cells, in immune responses to epicutaneously applied antigens ha...
