1. Utility of immunoglobulin isotypes against LID-1 and NDO-LID for, particularly IgG1, confirming the diagnosis of multibacillary leprosy
BACKGROUND Leprosy remains a health problem in many countries, with difficulties in diagnosis resulting in delayed treatment and more severe disabilities. Antibodies against several Mycobacterium leprae antigens have, however, shown value as diagnostic and/or prognostic markers. OBJECTIVES The objective of this study was to evaluate serum immunoglobulin

2. Isotipos IgG e IgM anti-dsDNA em pacientes com lúpus eritematoso sistêmico
IgG anti-dsDNA antibodies are associated to lupus nephritis. Recent data suggest that IgM isotype is nephroprotector. We evaluated the frequency of IgG anti-dsDNA in patients with Systemic lupus erythemathosus (SLE) and its relation between IgG/IgM proportion and clinical manifestations of the disease. This transversal study included 137 SLE patients accordi

3. Investigações de interações hiperfinas de DNA e anticorpos de diferentes linhagens de camundongos frente à infecção por T. cruzi pela espectroscopia de correlação angular gama-gama perturbada / Investigation of hyperfine interactions in DNA and antibody of different lineages of mice infected by T. cruzi by perturbed gamma-gamma angular correlation spectroscopy
In the present work perturbed angular correlation (PAC) spectroscopy was used to measured electric quadrupole interactions in DNA biomolecules of different mice lineages (A/J, C57BL/6, B6AF1, BXA1 e BXA2), samples of different isotypes of immunoglobulin G (IgG1, IgG2a e IgG2b) and active portions of complete and fragmented immunoglobulin responsible by the i

4. Análise cinética da resposta imune humoral contra a proteína recombinante SAG2A em pacientes com Toxoplasmose aguda
Proteínas recombinantes de Toxoplasma gondii têm sido utilizadas em diversos modelos experimentais, assim como para o diagnóstico sorológico da infecção humana por este parasito, principalmente com o intuito de diferenciar as fases aguda e crônica da toxoplasmose. Neste estudo, foi avaliada a cinética dos anticorpos IgM, IgA ,IgG e subclasses (IgG1 e

5. Vaccination with Trypanosoma rangeli modulates the profiles of immunoglobulins and IL-6 at local and systemic levels in the early phase of Trypanosoma cruzi experimental infection
In America, there are two species of Trypanosoma that can infect humans: Trypanosoma cruzi, which is responsible for Chagas disease and Trypanosoma rangeli, which is not pathogenic. We have developed a model of vaccination in mice with T. rangeli epimastigotes that protects against T. cruzi infection. The goal of this work was to study the pattern of specifi

6. A revacinaÃÃo com a bcg modula a produÃÃo de citocinas frente a antÃgenos do Mycobacterium leprae, em contatos menores de 15 anos de pacientes com hansenÃase. / Revaccination with BCG modulates cytokine production against antigens of Mycobacterium leprae in contacts under 15 years of leprosy patients.
Studies in different populations have shown that vaccination with BCG provides partial protection against leprosy. However, need of boost BCG vaccination and your impact in response immune against antigens of Mycobacterium leprae is poorly understood, mainly in children who are contacts of these patients with leprosy, and constitute population of risk for il

7. Identificação de isoformas antigênicas de Dermatophagoides pteronyssinus reconhecidas por anticorpos IgE e IgG1 em pacientes atópicos e não atópicos
The house dust mite Dermatophagoides pteronyssinus (Dp) is a major source of indoor allergens in the world and considered important for sensitization of genetically predisposed subjects. Some allergens from this mite can occur as isoallergens with differences in amino acid sequences or glycosylation, leading to differences in allergenic sensitization. The ai

8. A função da IL-10 na paracoccidioidomise pulmonar murina. / The role of IL-10 in murine pulmonary paracoccidioidomycosis.
Cellular immunity is the main defense mechanism of hosts infected by the Paracoccidioide brasiliensis (Pb), a dimorphic fungus that causes the most important systemic mycosis in Latin America. IFN-g activated macrophages participate in this activity that is antagonized by IL-10 an anti-inflammatory cytokine. Both, in the human pathology a

9. Biotin-avidin sandwich elisa with specific human isotypes IgG1 and IgG4 for Culicidae mosquito blood meal identification from an epizootic yellow fever area in Brazil
With a view toward investigating the feeding behavior of Culicidae mosquitoes from an area of epizootic yellow fever transmission in the municipalities of Garruchos and Santo Antônio das Missões, Rio Grande do Sul State, Brazil, specimens were collected by aspiration from September 2005 to April 2007. The engorged females were submitted to blood meal ident

The knowledge of mosquitoes Culicidae host feeding patterns permits to clarify some aspects related to zoonosis transmission and to estimate the degree of human-vector contact which is relevant in epidemiological studies. Aiming to explore the feeding behavior of these mosquitoes, specimens were collected in the municipalities of Santo Antônio das Missões

Leptospirosis is a zoonotic disease caused by pathogenic bacteria belonging to the Leptospira genus. Several mammals may carry the agent, and rats are the most important source of human infection in urban settings. The wide spectrum of clinical manifestations varies from mild cases, with fever and headaches, to severe presentations, with liver and kidney fai

Resposta imune frente à Bothropstoxina -1 irradiada com 60Co: identificação das principais citocinas envolvidas e a participação de substâncias scavengers / Immune response against the irradiated Bothropstoxin-1: Identification of main cytokines involved and the participation of scavengers substances
Considering the effects of gamma radiation on proteins and the ability of immune system to recognize modified macromolecules, we have identified the major cytokines involved in immune response of B10.PL, BALB/c and Knockout- IFN-/- mice exposed to native or irradiated bothropstoxin-1 (BTHX-1), in the presence and absence of scavengers substances. In order to
