1. Bullous pemphigoid and milia: prevalence and clinical laboratory findings in a Brazilian sample
Abstract Background: Bullous pemphigoid (BP) associated with milia lesions has been increasingly reported, but its prevalence has not been reported in a Brazilian BP population yet. Objectives: To describe the occurrence and clinical-laboratorial findings of BP-milia association in a southeastern Brazilian sample. Methods: A descriptive study based on the

3. Desensitization using IVIG alone for living-donor kidney transplant: impact on donor-specific antibodies
Resumo Introdução: Sensibilização HLA é uma barreira ao transplante em pacientes sensibilizados. Há poucos dados publicados sobre dessensibilização utilizando somente imunoglobulina intravenosa humana polivalente (IgIV). Métodos: Revisamos retrospectivamente prontuários de 45 pacientes com prova cruzada positiva por citotoxicidade dependente do c

4. The rs11755527 polymorphism in the BACH2 gene and type 1 diabetes mellitus: case control study in a Brazilian population
ABSTRACT Objective Type 1 diabetes mellitus (T1DM) is an autoimmune disorder caused by a complex interaction between environmental and genetic risk factors. BTB domain and CNC homolog 2 (BACH2) gene encodes a transcription factor that acts on the differentiation and formation of B and T lymphocytes. BACH2 is also involved in the suppression of apoptosis an

5. Flucloxacillin-Induced Hepatotoxicity - Association with HLA-B*5701
RESUMO A hepatotoxicidade à flucloxacilina é rara e classifica-se como idiossincrática, uma vez que é dependente da suscetibilidade individual, não expectável e independente da dose. Apresentamos o caso de um homem, 74 anos, antecedentes de gamapatia monoclonal e hábitos alcoólicos de 24 g/dia, com quadro de astenia, anorexia, náuseas, desconforto a

6. HLA-alleles class I and II associated with genetic susceptibility to neuromyelitis optica in Brazilian patients
RESUMO Objetivo: Estudar a suscetibilidade genética a neuromielite óptica (NMO) assim como sua relação com o genótipo HLA na população do sul do Brasil. Métodos: Nós analisamos pacientes com NMO que preenchiam os critérios diagnósticos de Wingerchuk para NMO, com presença do anticorpo anti-AQP4-IgG no soro. O genótipo HLA foi realizado usando

7. Standardization and quality assessment for clinical grade mesenchymal stem cells from human adipose tissue
Abstract Background Mesenchymal stem cells have immense potential in stem cell-based therapies, however there is a pre-requisite to develop a curative cell dose. Adipose tissue-derived mesenchymal stem cells are promising mainly due to their potential abundance, immunomodulatory effect and remarkable differentiation potential. Nevertheless, senescence may d

8. Immunohistochemical evaluation of HLA-G and FoxP3+ T regulatory cells in oral cavity and lower lip squamous cell carcinomas
Abstract: Human Leukocyte Antigen G (HLA-G) is a molecule involved in the tumor immunosuppression and also in the generation of regulatory T (Treg) cells, thus leading to evasion to the immune system host, and consequently, contributing to tumor progression in several cancers. The aim of this study was to evaluate the immunoexpression of HLA-G by tumor cells

9. Type-2 diabetes alters the basal phenotype of human macrophages and diminishes their capacity to respond, internalise, and control Mycobacterium tuberculosis
BACKGROUND Type 2 diabetes (T2D) is a risk factor for the development of tuberculosis (TB), although the associated mechanisms are not known. OBJECTIVES To study the association between T2D and the basal phenotype of macrophages, and their immune response to Mycobacterium tuberculosis (Mtb) infection. METHODS We evaluated the influence of T2D on the re

10. Immune development in HIV-exposed uninfected children born to HIV-infected women
ABSTRACT Immunological and clinical findings suggestive of some immune dysfunction have been reported among HIV-exposed uninfected (HEU) children and adolescents. Whether these defects are persistent or transitory is still unknown. HEU pediatric population at birth, 12 months, 6-12 years were evaluated in comparison to healthy age-matched HIV-unexposed contr

11. Antígeno leucocitário humano HLADRB1 é determinante de susceptibilidade para a doença do refluxo
RESUMO CONTEXTO A doença do refluxo gastroesofágico (DRGE) caracteriza-se por diversos sintomas. Há evidências de um componente genético para a doença de refluxo suportado pela agregação familiar desta doença. OBJETIVO Investigar se certos genes de antígeno de leucócito humano HLA-DRB1 são associados à DRGE. MÉTODOS Pacientes e indivíduos c

12. Uso de everolimo de novo em receptores de transplante renal com doador vivo HLA idêntico
Resumo Introdução: Receptores de rim de doadores vivos HLA-idêntico apresentam menor risco para rejeição aguda e maior sobrevida do enxerto, quando comparado a outros tipos de transplante. Um regime imunossupressor sem inibidor de calcineurina (ICN) pode melhorar ainda mais esses resultados, através da redução de eventos cardiovasculares, metabólic
