The Cells of the Islets of Langerhans [PDF]
Journal of Clinical Medicine, 2018 Islets of Langerhans are islands of endocrine cells scattered throughout the pancreas. A number of new studies have pointed to the potential for conversion of non-β islet cells in to insulin-producing β-cells to replenish β-cell mass as a means to treat ...

Journal of Investigative Dermatology, 1965 Since Langerhans (1) first described the presence of gold-positive dendritic cells in the epidermis, their nature has been an unsettled question. These cells, which morphologically resemble melanocytes, are free of pigment and are not seen when stained for melanin nor when the dopa stain is used; but they can be demonstrated with gold chloride methods.

Trauma of Peripheral Innervation Impairs Content of Epidermal Langerhans Cells [PDF]
Diagnostics, 2022 Langerhans cells represent the first immune cells that sense the entry of external molecules and microorganisms at the epithelial level in the skin. In this pilot case-study, we evaluated Langerhans cells density and progression of epidermal atrophy in ...

Antigen Presentation and Allogeneic Stimulation by Langerhans Cells [PDF]
, 1980 Isolated Langerhans cells were studied for 2 immunologic functions, the ability to present antigen to sensitized T lymphocytes and the ability to act as stimulator cells for mixed lymphocyte reactions. Langerhans cells can perform both of these functions.

Immunohistochemical analysis of S100-positive epidermal Langerhans cells in dermatofibroma, [PDF]
Anais Brasileiros de Dermatologia, 2020 Dermatofibroma is a dermal fibrohistiocytic neoplasm. The Langerhans cells are the immunocompetent cells of the epidermis, and they represent the first defense barrier of the immune system towards the environment.

Immunohistochemical staining of Langerhans cells in HPV-positive and HPV-negative cases of oral squamous cells carcinoma [PDF]
Journal of Applied Oral Science, 2011 The Human Papillomavirus (HPV) has been strongly implicated in development of some cases of oral squamous cell carcinoma (OSCC). However, the immunological system somehow reacts against the presence of this virus.

Pathophysiology of Langerhans cells
Journal of Oral and Maxillofacial Pathology, 2012 Langerhans cells (LCs) were first described by Paul Langerhans, in 1868, as dendritically shaped cells, which were located in the squamous epithelia of epidermis.

The Potentials and Pitfalls of a Human Cervical Organoid Model Including Langerhans Cells [PDF]
Viruses, 2020 Three-dimensional cell culturing to capture a life-like experimental environment has become a versatile tool for basic and clinical research. Mucosal and skin tissues can be grown as “organoids” in a petri dish and serve a wide variety of research ...
