Morphometric analysis of dendritic cells from anal mucosa of HIV-positive patients and the relation to intraepithelial lesions and cancer seen at a tertiary health institution in Brazil Análise morfométrica das células dendríticas da mucosa anal de pacientes HIV-positivos e relação com as lesões intraepiteliais e o câncer numa instituição de saúde terciária no Brasil

Acta Cirúrgica Brasileira, 2011
PURPOSE: To morphometrically quantify CD1a+ dentritic cells and DC-SIGN+ dendritic cells in HIV-positive patients with anal squamous intraepithelial neoplasia and to evaluate the effects of HIV infection, antiretroviral therapy and HPV infection on ...

Tumor necrosis factor-α, CD1A and CD1E genetic polymorphisms in Guillain-Barré syndrome: A study from India

Annals of Indian Academy of Neurology, 2023
Background: Guillain–Barré Syndrome (GBS) is an acute acquired autoimmune inflammatory disorder of peripheral nerves and roots. The pathogenesis is essentially an aberrant post-infectious immune response in a genetically susceptible host milieu.

CTLA4 is expressed on mature dendritic cells derived from human monocytes and influences their maturation and antigen presentation [PDF]

, 2011
Background Dendritic cells (DCs) initiate immune responses through their direct interaction with effector cells. However, the mechanism by which DC activity is regulated is not well defined. Previous studies have shown that CTLA4 on T cells regulates DCs

Two canine CD1a proteins are differentially expressed in skin [PDF]

Immunogenetics, 2008
Lipid antigens are presented to T cells by the CD1 family of proteins. In this study, we characterize the complete dog (Canis familiaris) CD1 locus, which is located on chromosome 38. The canine locus contains eight CD1A genes (canCD1A), of which five are pseudogenes, one canCD1B, one canCD1C, one canCD1D, and one canCD1E gene.

A dendritikus sejtek szerepe az immunológiai szinapszis kialakításában, a T-limfociták homeosztázisának és aktiválásának szabályozásában = The role of dendritic cells in the formation of immunological synapses and in the regulation of T lymphocyte homeostasis and activation [PDF]

, 2007
A CD14+ monociták CD1a- és CD1a+ DS-ekké differenciálódnak, de a CD1a- és CD1a+ sejtek arányát a szérum lipoproteinek dózis függően befolyásolják. Kinetikai vizsgálatok igazolták, hogy az éretlen CD1a- DS-ek CD1a+ sejtekké differenciálódnak, ezt az ...

An improved ontological representation of dendritic cells as a paradigm for all cell types [PDF]

, 2009
The Cell Ontology (CL) is designed to provide a standardized representation of cell types for data annotation. Currently, the CL employs multiple is_a relations, defining cell types in terms of histological, functional, and lineage properties, and the ...

CD1a expression in psoriatic skin following treatment with propylthiouracil, an antithyroid thioureylene [PDF]

, 2003
BackgroundThe antithyroid thioureylenes, propylthiouracil (PTU) and methimazole (MMI), are effective in the treatment of patients with plaque psoriasis. The mechanism of action of the drugs in psoriasis is unknown.

Cutaneous Crystal‐Storing Histiocytosis With Marginal Zone Lymphoma. A Case Report With A Striking Clinical Presentation

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Cutaneous crystal‐storing histiocytosis (CSH) is an extremely rare histopathologic finding of histiocytes accumulating crystals of immunoglobulin or paraproteins, often associated with lymphoplasmacytic malignancies. It commonly presents in a wide age range of both female and male adults with a history of a lymphoproliferative disorder ...

CD1a and langerin: acting as more than Langerhans cell markers [PDF]

Journal of Clinical Investigation, 2004
Langerhans cells (LCs) represent a unique DC subset populating the outermost body surface, i.e., the epidermis. Although CD1a and langerin (CD207) are used as specific markers to distinguish LCs from other DC subsets, their immunological functions have remained mostly unknown.

An unusual case of intertrigo in an adult caused by purely cutaneous Langerhans cell histiocytosis [PDF]

, 2016
We report a case of persistent intertrigo in an adult, eventually diagnosed as cutaneous Langerhans cell histiocytosis (LCH). It is known that LCH has a predilection for intertriginous areas, however purely cutaneous disease as in our case, is uncommon ...
