Skin-limited Langerhans cell histiocytosis in an adult: a case report

open access: yesDermatology Reports, 2021
Langerhans cell histiocytosis (LCH) is an idiopathic group of disorders characterized histologically by proliferation and infiltration of tissue by Langerhans cell-type histiocytes. This disease can affect various organs.

Pathophysiology of Langerhans cells

open access: yesJournal 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. Later on, these cells were identified in all stratified squamous epithelium of mammals. Dendritic cells (DCs) play an important role in local defense mechanisms in the epithelium.

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.

A Transcriptionally Distinct Intermediate Activation State Precedes Langerhans Cell Migration From the Epidermis

open access: yesAdvanced Science, EarlyView.
A transcriptionally distinct intermediate Langerhans cell state is identified between steady and migratory populations during skin injury. Integrated single‐cell transcriptomics, flow cytometry, and intravital imaging reveal state‐specific markers and implicate complement signaling, particularly C3, in regulating Langerhans cell accumulation near ...

Nodal Langerhans cell neoplasm: detailing the diagnostic quandaries

open access: yesAutopsy and Case Reports, 2022
Langerhans cells, found in the supra-basal region of the mucous membranes in the epidermis of the skin, in lymph nodes and thymus, function as antigen-presenting cells within the histiocyte system.

Human Fibroblast–Myeloid Cell Tissue Atlas Across the Lungs, Synovium, Skin, and Heart

open access: yesArthritis &Rheumatology, EarlyView.
Objective The availability of single‐cell RNA sequencing (scRNAseq) data in different tissues and disease states provides an opportunity to compare cellular subsets and identify common and unique cellular activation. In this study, we aimed to characterize shared and tissue‐specific myeloid and stromal phenotypes and to uncover key cellular subtypes ...

Clinical periodontal diagnosis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...
