1. Phenotypic analysis of regulatory T cells and dendritic cells in human infections with P. vivax and P. falciparum. / Análise fenotípica de células T reguladoras e células dendríticas na infecção humana por Plasmodium vivax e Plasmodium falciparum
This study compares levels of circulating cytokines and peripheral-blood populations of CD4+CD25+ Treg cells, based on the expression of FOXP3 and CTLA-4, and dendritic cells (DCs) in individuals infected with P. falciparum, P. vivax or co-infected with both species and in healthy controls living in an area of unstable transmission of malaria in the Brazilia

2. Manifestações clínicas e patogênese da plaquetopenia na malária
Thrombocytopenia is a well-known hematological complication of malaria, although its pathogenesis is still unclear. The objectives of the present work were to estimate the frequency and the clinical manifestations of thrombocytopenia in malaria, and to investigate a possible role for the circulating immune complexes (CIC) and of platelet aggregation in vitro

3. "Resposta imune humoral na malária humana: quantidade e qualidade de anticorpos anti-Plasmodium falciparum" / Humoral immune response in human malaria : quantity and quality of anti-Plasmodium falciparum antibodies
Neste estudo avaliamos a resposta imune humoral de indivíduos naturalmente expostos à malária em áreas endêmicas no Brasil. Os anticorpos IgG, IgG1, IgG2, IgG3, IgG4, IgM, IgE e IgA anti-formas eritrocitárias de Plasmodium falciparum foram determinadas por ELISA. Anticorpos IgG, IgG1, IgG2 de alta avidez e IgG3 de baixa avidez predominaram nos indivíd

4. Plasmodium interspersed repeats: the major multigene superfamily of malaria parasites
Functionally related homologues of known genes can be difficult to identify in divergent species. In this paper, we show how multi-character analysis can be used to elucidate the relationships among divergent members of gene superfamilies. We used probabilistic modelling in conjunction with protein structural predictions and gene-structure analyses on a whol

5. Susceptibility of different strains of mice to hepatic infection with Plasmodium berghei.
Despite the low susceptibility of BALB/c mice to hepatic infection by Plasmodium berghei, this animal model is routinely used to investigate the basic biology of the malaria parasite and to test vaccines and the immune response against exoerythrocytic (EE) stages derived from sporozoites. A murine model in which a large number of EE parasites are established
