1. Cutaneous tuberculosis: epidemiological, clinical, diagnostic and therapeutic update
Abstract Tuberculosis is certainly one of the diseases considered to be ancient on planet Earth. The etiological agent of tuberculosis is Mycobacterium tuberculosis. This terrible bacterial infection still results in severe socioeconomic consequences to date, and its complete eradication represents a great challenge. It constitutes one of the most important

2. Positive Correlation Between the Level of Interferon-Gamma and the Severity of Periodontitis
Abstract Objective: To examine the IFN-γ levels in patients with periodontitis and determine the difference in the levels of IFN-γ with the severity of the disease. Material and Methods: The study design was cross-sectional, and the sample consisted of 31 patients, aged between 18 and 64 years. Plaque index (PlI), calculus index (CI), and papillary bleed

3. Differential expression of T helper cytokines in the liver during early pregnancy in sheep
Abstract Liver plays important roles in the innate and adaptive immunity, and contributes to the maternal immune adjustments during pregnancy in mice and rats. T helper 1 (Th1) and Th2 cytokines are related to immune response. However, expression of Th1 and Th2 cytokines in maternal livers is unclear during early pregnancy in sheep. In this study, livers wer

4. QuantiFERON-TB Gold In-Tube test in active tuberculosis patients and healthy adults
ABSTRACT Interferon-gamma (IFN-γ) release assays have improved latent tuberculosis (TB) detection and have been considered promising for the diagnosis of TB disease. However, diagnosis efficacy data is limited in high burden countries. The aim of this study was to determine the diagnostic potential of the QuantiFERON-TB Gold In-Tube (QFT-GIT) test for the d

5. IFN-γR2 is strongly expressed on endothelial cells of gingival tissues from patients with chronic periodontitis
Abstract Chronic periodontitis (CP) is characterized by gingival inflammation and bone destruction. It has been reported that interferon-gamma (IFN-γ) levels are high in CP patients; however, the IFN-γ receptor (IFN-γR) has not been studied in gingival tissue from these patients. Objective: To evaluate IFN-γ levels and IFN-γR expression in gingival tis

6. Single nucleotide polymorphisms of cytokine-related genes and association with clinical outcome in a Chagas disease case-control study from Brazil
BACKGROUND The severity of chronic chagasic cardiomyopathy (CCC), the most frequent clinical outcome of Chagas disease (CD), has been associated with cytokine-enriched heart tissue inflammation, and high serum levels of transforming growth factor (TGFβ), interferon-gamma (IFNγ), and tumour necrosis factor (TNF). Conversely, increased interleukin (IL)-10 s

7. Social conditions and immune response in human immunodeficiency virus-seropositive pregnant women: a cross-sectional study in Brazil
Abstract INTRODUCTION The functioning of the immune system during pregnancy is altered in both human immunodeficiency virus (HIV)-infected and uninfected women. Unfavorable socioeconomic conditions have been indicative of higher morbidity and mortality and worsening of the immune system. The aim of this study was to correlate social status with levels of i

8. Immune Regulatory Effects of Enteromorphaclathrata Polysaccharides on Nd Attenuated Vaccine in a Chicken Model Infected with Reticuloendotheliosis Virus
ABSTRACT Reticuloendotheliosis virus (REV) infection has frequently affected the poultry industry in recent years. The infection with REV weakens the immune responses of the infected poultry. It is reported that Enteromorphaclathrata polysaccharides are capable of regulating immune function. In order to investigate the immuno regulatory effects of Enteromorp

9. IL-10 down-regulates the expression of survival associated gene hspX of Mycobacterium tuberculosis in murine macrophage
Abstract Mycobacterium tuberculosis (MTB) adopts a special survival strategy to overcome the killing mechanism(s) of host immune system. Amongst the many known factors, small heat shock protein 16.3 (sHSP16.3) of MTB encoded by gene hspX has been reported to be critical for the survival of MTB. In the present study, the effect of recombinant murine interfero

10. Taxa de resultados indeterminados de ensaio de liberação de interferon-gama entre pessoas infectadas pelo HIV
RESUMO Objetivo: Avaliar a frequência de resultados indeterminados de um interferon-gamma release assay (IGRA, ensaio de liberação de interferon-gama) e os fatores relacionados com esses resultados em pessoas vivendo com HIV/AIDS (PVHA). Métodos: Foram avaliadas 81 PVHA na região Centro-Oeste do Brasil, por meio do teste tuberculínico e de um IGRA. I

11. Expression analysis of three immune genes Interferon-gamma, Mx and Interferon regulatory factor-1 of Japanese flounder ( Paralichthys olivaceus )
ABSTRACT IFN-γ (Interferon-gamma), Mx and IRF-1 (Interferon regulatory factor-1) are main immune-related genes and they play important roles in the innate immune system of vertebrates. In this study, the expression level of the three immune-related genes in twelve tissues of normal adult Japanese flounder was detected using semi-quantitative RT-PCR. Thirtee

12. Clinical Study of Extrapulmonary Head and Neck Tuberculosis: A Single-Institute 10-year Experience
Introduction Although the incidence of tuberculosis (TB) in Japan has been decreasing yearly, Japan remains ranked as an intermediate-burden country for TB. Objective This study aims to investigate the current situation of head and neck extrapulmonary TB (EPTB) diagnosed in our department. Methods We retrospectively reviewed the clinical records of 47
