1. Congenital solitary reticulohistiocytosis (Hashimoto - Pritzker)
Abstract Congenital and self-healing Hashimoto-Pritzker reticulohistiocytosis is the benign variant of the Langerhans cell histiocytosis (LCH) group. It is characterized by multiple skin lesions (congenital or appearing during the first days after birth), without systemic manifestations and spontaneous resolution in days to months. The authors report the cas

2. Immunohistochemical analysis of S100-positive epidermal Langerhans cells in dermatofibroma,
Abstract 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. The objective was to immunohistologically compare the densities of S100-positive Langerhans cells in the healthy peritumoral epidermis ag

3. Aspects of Langerhans cells and TNF-α in the cutaneous immunity of anogenital warts,
Abstract Background: Anogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of th

6. 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

7. In situ immune response in human dermatophytosis: possible role of Langerhans cells (CD1a+) as a risk factor for dermatophyte infection
ABSTRACT Dermatophytosis is a cutaneous mycosis caused by a plethora of keratinophilic fungi, but Trichophyton rubrum is the most common etiological agent. Despite its high prevalence worldwide, little is known about the host defense mechanisms in this infection, particularly the in situ immune response. Using an immunohistochemistry approach, we investigate

8. Congenital self-healing reticulohistiocytosis with spontaneous regression
Abstract: Congenital self-healing reticulohistiocytosis is a rare, benign, self-limiting variant of Langerhans cell histiocytosis (LCH). LCH encompasses a group of idiopathic disorders characterized by the clonal proliferation of Langerhans cells. Congenital self-healing reticulohistiocytosis typically appears at birth or in the neonatal period as isolated c

9. Genetic characterisation of Langerin gene in human immunodeficiency virus-1-infected women from Bahia, Brazil
Studies on human genetic variations are a useful source of knowledge about human immunodeficiency virus (HIV)-1 infection. The Langerin protein, found at the surface of Langerhans cells, has an important protective role in HIV-1 infection. Differences in Langerin function due to host genetic factors could influence susceptibility to HIV-1 infection. To verif

10. Correlação do perfil das células dendríticas com a resposta imune celular T CD4+ e T CD8+ na infecção experimental do camundongo BALB/c por Leishmania (Leishmania) amazonensis e Leishmania (Viannia) braziliensis / Correlation to the profile of dendritic cells and CD4+ and CD8+ T cellular immune response in experimental infection of BALB/c mice by Leishmania (Leishmania) amazonensis and Leishmania (Viannia) braziliensis
L. (L.) amazonensis (La) e L. (V.) braziliensis (Lb) podem causar um espectro de manifestações clínicas e imunopatológicas no homem, sendo La responsável pela forma anérgica difusa e Lb pela forma mucocutânea da doença, formas polares e de elevada gravidade. Neste sentido, o objetivo do presente estudo foi avaliar os aspectos da resposta imune celula

11. Células dendríticas plasmocitoides, dendrócitos dérmicos fator XIIIa positivos, macrófagos e expressão da forma induzida da óxido nítrico sintase na resposta tecidual cutânea de leishmaniose tegumentar americana / Plasmacytoid dendritic cells, Factor XIIIa-positive dermal dendrocytes, macrophages and inducible nitric oxide synthase expression in American tegumentary leishmaniasis skin lesions
Em todas as formas clínicas da leishmaniose tegumentar americana os macrófagos são as células efetoras mais importantes na destruição do parasita intracelular. As células dendríticas são células apresentadoras de antígeno localizadas nos sítios de inoculação, como pele e mucosa. Os dendrócitos dérmicos Fator XIIIa positivos são células deri

12. O efeito pró-apoptótico de oligômeros da amilina humana não é potencializado pela lipotoxicidade em ilhotas pancreáticas de rato em cultura / The pro-apoptotic effect of human amylin oligomers is not potentiated by lipotoxicity in rat pancreatic islets in culture
The amyloid deposit is a common histopathological feature in patients with type 2 diabetes mellitus (T2DM) and it seems to be related to the pancreatic beta cell dysfunction characteristic of this disease. A study previously developed in our laboratory found that human amylin oligomers decrease mRNA expression of the glucose-dependent insulinotropic polypept
