1. Enhancing immune effects of a DNA vaccine against kidney cancer using CD40L as an adjuvant
The use of specific combinations of antigens and adjuvant represents a promising approach for increasing the immunogenicity of DNA vaccines. In the present study, we evaluated the immunity and antitumor effects of DNA vaccines with G250 as the target antigen in a mouse model of renal cell carcinoma. We constructed two recombinant plasmids, pVAX1-G250 and pVA

2. Preservation of cytotoxic granule production in response to mycobacterial antigens by T-lymphocytes from vertically HIV-infected Brazilian youth on effective combined antiretroviral therapy
ABSTRACT Background: HIV infection harms adaptive cellular immunity mechanisms. Long-term virological control by combined antiretroviral therapy (cART) reduces the risk of mycobacterial infections. Thus, we aimed to study cellular responses to mycobacterial antigens in 20 HIV-infected adolescents with at least one year of virological control (HIV-RNA <40 co

3. Humoral and cellular immune response of mice challenged with Yersinia pestis antigenic preparations
ABSTRACT Objectives: The plague, which is an infectious disease caused by Yersinia pestis, still threatens many populations in several countries. The worldwide increase in human plague cases and the potential use of the bacteria as a biological weapon reinforce the need to study the immunity that is induced by potential vaccine candidates. To determine the

4. Generation of potent cytotoxic T lymphocytes against in male patients with non-muscle invasive bladder cancer by dendritic cells loaded with dying T24 bladder cancer cells
ABSTRACT Background In order to induce a potent cytotoxic T lymphocyte (CTL) response in dendritic cell (DC)-based immunotherapy for bladder cancer, various tumor antigens can be loaded onto DCs. Objective The aim of this study was to establish a method of immunotherapy for male patients with non-muscle invasive bladder cancer (NMIBC), using bladder canc

5. Angiogênese, células-tronco neoplásicas CD34+ e sinvastatina em modelo de carcinogênese mamária induzida quimicamente / Angiogenesis, CD34+ cancer stem-cells and simvastatin in a chemically induced mammary carcinogenesis model
Breast cancer is the most common malignancy and the leading cause of death from cancer among females worldwide. Despite all the research and all the progress achieved so far, the morbidity and mortality due to this cancer remains high in patients at advanced stages. Recently, it was described a new model of carcinogenesis in which stem cells (SC) could be re

6. Effect of aging and oral tolerance on dendritic cell function
Oral tolerance can be induced in some mouse strains by gavage or spontaneous ingestion of dietary antigens. In the present study, we determined the influence of aging and oral tolerance on the secretion of co-stimulatory molecules by dendritic cells (DC), and on the ability of DC to induce proliferation and cytokine secretion by naive T cells from BALB/c and

7. Análise fenotípica e funcional de células dendríticas e monócitos, em pacientes com tuberculose pulmonar infectados por helmintos intestinais
The Tuberculosis (TB) remains a global threat to humanity, which no effective vaccine available until now. Epidemiological studies have shown that Mycobacterium tuberculosis (MTB) and helminths are co-endemic in many regions in the world, and that co-infections with these pathogens are frequent. The intestinal helminths infection may be a risk factor to the

8. Estudo de células dendríticas, expressão das citocinas TNF-alfa, IFN-gama e IL-10 e da molécula de adesão E-caderina em lesões vulvares induzidas pelo papilomavírus humano / Study of dendritic cells, cytokines TNF-alpha, IFN-gamma and IL-10 and the adhesion molecule E-cadherin in vulvar lesions induced by human papillomavirus
INTRODUCTION: The human papillomavirus (HPV) is the most frequent agent in sexually transmitted diseases and is responsible for almost 40% of vulvovaginal cancer. We studied the immune response in vulvar lesions, considering the CD1a+, FXIIIa+ and S-100+ dendritic cells, TNF-, IFN- and IL-10 cytokines and the adhesion molecule E-cadherin. METHODS: We used 49

9. Interections between CD40/CD40L and PPARs signaling pathways / Interação entre as vias de sinalização CD40/CD40L e os PPARs
The membrane receptor CD40 and its ligand CD40L play an important role in the interface between innate and acquired immunity. Dysfunction of this signaling pathway was described in inflammatory and autoimmune diseases. In systemic lupus erythematosus (SLE), increased serum levels of soluble CD40L have been detected, where it plays a significant role in the g

10. Primary bone lymphomas : comparison of the immunoexpression of apoptosis related proteins and adhesion molecules with nodal lymphomas and lymphomas metastatic to bone / Linfomas osseos primarios : estudo comparativo com linfomas nodais e linfomas osseos metastaticos quanto a imunoexpressão de proteinas relacionadas a apoptose, regulação do ciclo celular e adesão celular
The incidence of extranodal lymphomas is increasing in the last decades. Around 20 to 40% of B-cell non-Hodgkin lymphomas (NHL) arise outside the lymph nodes and may present distinct biological behavior, as compared to the corresponding nodal counterpart of similar histological grade. The heterogeneity of large B-cell lymphomas (LBCL) has been matter of vari

11. Abnormal humoral immune response to influenza vaccination in pediatric type-1 human immunodeficiency virus infected patients receiving highly active antiretroviral therapy
Given that highly active antiretroviral therapy (HAART) has been demonstrated useful to restore immune competence in type-1 human immunodeficiency virus (HIV-1)-infected subjects, we evaluated the specific antibody response to influenza vaccine in a cohort of HIV-1-infected children on HAART so as to analyze the quality of this immune response in patients un

12. CD4 T cells producing pro-inflammatory interleukin-17 mediate high pathology in schistosomiasis
In murine schistosomiasis mansoni, pronounced CD4 T cell-mediated, egg-induced, hepato-intestinal immunopathology and death, whether genetically determined or elicited experimentally, are associated with failure to down-regulate a net pro-inflammatory immune response. Important evidence contributing to this notion comes from the observation that immunization
