Langerhans cell histiocytosis [PDF]

open access: yesBlood, 2020
Abstract Langerhans cell histiocytosis (LCH) is caused by clonal expansion of myeloid precursors that differentiate into CD1a+/CD207+ cells in lesions that leads to a spectrum of organ involvement and dysfunction. The pathogenic cells are defined by constitutive activation of the MAPK signaling pathway.

Phagocytosis of antigens by Langerhans cells [PDF]

open access: yes, 1992
Mature dendritic cells (DC) isolated from lymphoid tissues initiate antigen-specific T-dependent responses even though they are non-phagocytic and weakly pinocytic, whereas Langerhans cells (LC; immature DC) can process protein antigens but are poorly ...

Primary Langerhans Cell Histiocytosis of the Extrahepatic Bile Duct Occurring in an Adult Patient

open access: yesBalkan Medical Journal, 2018
Background: Langerhans cell histiocytosis is characterized by an abnormal proliferation of neoplastic Langerhans cells. Langerhans cell histiocytosis commonly affects the pediatric population, whereas presentation in adults remains a rare event.

The Potentials and Pitfalls of a Human Cervical Organoid Model Including Langerhans Cells

open access: yesViruses, 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 ...

Identification of proteases employed by dendritic cells in the processing of protein purified derivative (PPD) [PDF]

open access: yes, 2004
Dendritic cells (DC) are known to present exogenous protein Ag effectively to T cells. In this study we sought to identify the proteases that DC employ during antigen processing.

Adult-onset perianal Langerhans cell histiocytosis presenting as pruritus ani: a case report and review of the literature

open access: yesJournal of Medical Case Reports, 2021
Background Langerhans cells belong to the histiocytic system and give rise to two tumors: Langerhans cell histiocytosis and Langerhans cell sarcoma. Clinical aggressiveness and degree of atypia distinguish the two neoplasms. Langerhans cell histiocytosis
