1. Distribution of Dendritic Cells in AIDS-Associated Oral Kaposi’s Sarcoma
Resumo O objetivo deste estudo foi determinar se a distribuição das células de Langerhans (CL) e das células dendríticas intersticiais (CDI) está alterada no sarcoma de Kaposi oral associado à AIDS quando comparado às lesões orais altamente vasculares HIV-negativas. 51 casos de sarcoma de Kaposi oral associado à AIDS e 20 de lesões orais altamente

2. ANÁLISE DO COURO CABELUDO DE MULHERES COM AIDS SUBMETIDAS À AUTÓPSIA: aspectos epiteliais, foliculares e imunológicos
Introduction: Several diseases of skin and scalp (S) occur with greater clinicalseverity in individuals infected with HIV. With the emergence and effectiveness of HAART, there was a decrease in the incidence of the processes associated withimmunodeficiency, and the emergence of apparently less serious problems, such as onychodystrophy, seborrheic dermatitis

3. Immunohistochemical staining of Langerhans cells in HPV-positive and HPV-negative cases of oral squamous cells carcinoma
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. Among the cells involved in such mechanism of defense Langerhans cells (LC) stand out, which are responsible for processing and presenting antigen

4. Langerhans cells in periodontal disease of HIV- and HIV+ patients undergoing highly active antiretroviral therapy
The aim of this study was to assess and compare quantitatively the presence of S100+ Langerhans cells (LC) by immunochemistry techniques in HIV+ and HIV- gingivitis and periodontitis subjects. Additionally, it aimed to evaluate the correlation among densities of these cells with CD4+ and CD8+ T cells, and viral load levels in HIV+ subjects, all using Highly

5. Avaliação das células de Langerhans na língua de pacientes autopsiados com AIDS em estágio avançado / Expression of Langerhans cells in the tongue of autopsied patients with advanced AIDS
The tongues of AIDS patients can be affected by opportunistic infections and neoplasms. Objectives: to quantify and compare the expression of Langerhans cells (LC) in lesional and non lesional areas in the tongue from patients with and without AIDS (control group), using autopsy material. Methods: we analysed the expression of CD1a, HLA-DR and CD83 using imm

6. CÃlulas de Langerhans no colo uterino de mulheres HIV â soropositivas com neoplasia intraepitelial cervical
Objective: To compare the density of cervical mucosa Langerhans Cells (LC) in HIVpositive women with HSIL or LSIL. Method: Fifty-five HIV-infected women with colposcopic and histocitologic alterations were assessed for SIL and LC density between March 2005 and March 2006. LC were identified using the S-100 immunohistochemical stain. Polymerase chain reaction

7. Detecção imuno-histoquímica de células de langerhans em granuloma dentário e cisto radicular
Dental Granuloma and Radicular Cysts represent chronic periapical lesions that frequently affect the jaw bones. The Langerhans Cells are dendritic antigen-presenting cells that initiate primary T-lymphocyte-dependent immune response T. These cells play a important role in normal and pathological epithelial tissues as those seen in periapical chronic lesions.

8. Papilomavírus humano (HPV) e células de Langerhans em carcinoma epidermóide oral
The Human Papillomavirus (HPV) has been strongly implicated on development of some cases of oral squamous cell carcinoma (OSCC). However, the immunological system somehow reacts against the presence of this virus. Among the cells involved on such mechanism of defense detaches the Langerhans cells (LC), which are responsible for processing and presenting anti

9. Dermal dendritic cell number correlates with serum autoantibody titers in Brazilian pemphigus foliaceus patients
Pemphigus foliaceus (PF) is an autoimmune bullous disease endemic in Brazil. Since serum IL-12 is increased in patients with PF and Langerhans cells (LC) produce IL-12, we titrated serum autoantibodies by indirect immunofluorescence, and quantified epidermal dendritic cells, known as LC, and dermal dendritic cells (DC). Biopsies of blistering lesions were ob

10. HistoquÃmica e anÃlise digital de imagens em neoplasias cutÃneas
This work evaluated alterations in the expression of carbohydrates and the density of tumour cells and Langerhans cells (LC) using lectin histochemistry, immunohistochemistry and computer image analysis in neoplasic cutaneous tissues. Biopsies of basal cell carcinoma (BCC, n=35), epidermoid carcinoma (EpC, n= 18), tricoepithelioma (TE, n=12), keratoacanthoma

11. Analise comparativa das caracteristicas microscopicas da lesão liquenoide na GVHD cronica e no liquen plano de boca
Lichen planus (LP) is a chronic mucocutaneous disease of unknown etiology, that frequently affects the oral mucosa. Microscopically, LP is characterized by areas of epithelial acantosis and atrophy, with disorganization of the basal layer, and by a subepithelial band-like mononuclear inflammatory infiltrate. Lichenoid lesion are diseases that present a simil

12. Phenotypic changes in Langerhans' cells after infection with arboviruses: a role in the immune response to epidermally acquired viral infection?
The role of Langerhans cells (LC) in the initiation of an immune response to a viral infection remains unclear. In vivo epidermal infection with the arboviruses West Nile virus and Semliki Forest virus significantly increased the expression of major histocompatibility complex class II antigens, CD54, and CD80 on LC. Thus, during an epidermally acquired viral
