1. Saliva collection and detection of anti- T. gondii antibodies of low-income school-age children as a learning strategy on hygiene, prevention and transmission of toxoplasmosis
ABSTRACT School-age children are a social group in which blood collection for laboratory testing can be perceived as an invasive procedure, with low acceptance and tolerance of stakeholders. This problem could be circumvented by replacing serum samples with saliva. For this purpose, and to make the collection of saliva samples playful and instructive for chi

2. Dendritic cells and their relation to apical peridontitis
Abstract: The purpose of this manuscript was to re-discuss apical periodontitis, apical biofilm, and its possible relationship with dendritic cells (DC). DCs are potent regulators of the immune system and their function is divided into three categories that involve the presentation of antigens: the presentation of antigens and activation of T cells; a not we

3. 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

4. The role of intradermal proliferation of T-cells in the pathogenesis of psoriasis
Abstract: BACKGROUND: Psoriasis is a common immune-mediated chronic inflammatory disease of the skin and joints, affecting 1-3% of the population. It is generally accepted that the pathogenesis of psoriasis involves accumulation of effector T-cells within lymph nodes and their subsequent migration into the skin through the blood system. Here we provide evid

5. Involvement of memory T-cells in the pathophysiology of chronic lymphocytic leukemia
The role of T-cells in the pathogenesis of chronic lymphocytic leukemia has recently gained much attention due to the importance of the constant interaction between neoplastic B-cells with microenvironment substratum and T-cells. It is believed that these interactions modulate the clinical course of the disease, mainly through the regulation of the expansion

6. Desenvolvimento e manutenção de memória imunológica após imunização contra Neisseria meningitidis B com a vacina VA-MENGOC-BC / Development and maintenance of immune memory after immunization against Neisseria meningitidis B with VA-MENGOC-BC .
Neisseria meningitidis é uma das principais causas de meningite bacteriana e septicemia em todo o mundo, acometendo principalmente crianças menores de 4 anos. Atualmente, não existe uma vacina universal contra o meningococo B (MenB). A imunidade protetora contra o meningococo caracteriza-se pela presença e persistência de anticorpos bactericidas, porém

7. Produção e caracterização do anticorpo monoclonal aDEC205 acoplado a proteína MSP-1 (19) de Plasmodium chabaudi. / Production and characterization of a monoclonal antibody aDEC205 coupled to MSP-1(19) protein from Plasmodium chabaudi.
Despite the strong activation of the immune system that occurs during infection by Plasmodium, the immunological memory to infection is restricted to patients residing in endemic areas. Thus it is important to the generation of methods to induce an effective immune response against the parasite. In this context, the targeting of antigens to the central cells

8. Impairment of spatial performance by continuous intensive noise: a behavioral view
A wide range of animal and human investigations have tested the neurobiological and immunological aspects of noise. Few studies, however, have explored the behavioral characteristics of noise on neuromotor movements. To examine this correlation, we tested the effects of continuous intensive noise on retention and contextual transfer in a spatial memory task

9. A dymanical approach to study the immunocompetence and the immunological tolerance of mammals.
In this paper we present an in silico study about immune tolerance, where phase transitions have been observed when antigen dosages were varied in virtual samples. Using a dynamical model to study the behavior of the immune system - presented in a previous edition of the International Symposium on Mathematical and Computational Biology -, we have identified

10. Uma aplicação da abordagem de Verhulst para investigar a influência da mutação antigênica na durabilidade da memória imune.
Modelos matemáticos têm sido utilizados para responder a várias questões imunológicas complexas como o processo de memória imunológica e a duração de vacinas, onde os mecanismos de regulação ainda não são suficientemente conhecidos. Neste artigo é apresentada uma abordagem in silico para simular o processo de mutação antigênica e suas implic

11. Etiology and immunology of infectious bronchitis virus
Infectious bronchitis virus (IBV) of chickens is currently one of the main diseases associated with respiratory syndrome in domestic poultry, as well as with losses related to egg production. The etiological agent is a coronavirus, which presents structural differences in the field, mainly in the S1 spike protein. The immune response against this virus is co

12. Inflammatory and Immunological Aspects of pulpitis Human Dental / Aspectos Inflamatórios e Imunológicos de Pulpites Dentárias Humanas
Immune and inflammatory cells may contribute to host defense and microenvironmental changes during the pathogenesis of dental pulpitis. This study evaluated the microscopic characteristics and densities (per mm2) of tryptase+ mast cells, CD4+ T helper lymphocytes, CD45RO+ memory T lymphocytes, foxp3+ T regulatory lymphocytes, CD20+ B lymphocytes, CD68+ macro
