1. Evaluation of the involvement of Toll like and C-type lectin receptors in the immunessuppression induced by high molecular weight components from Ascaris suum extract. / Avaliação da participação dos receptores do tipo Toll e lectinas tipo C na supressão da resposta imune induzida por componentes de alta massa molecular do extrato de Ascaris suum.
Helminths and antigens derived from them are potent immunemodulators. High molecular weight components of Ascaris suum extract (PI) suppress the anti-ovalbumin response. The PI components inhibit in antigen-presenting cells (APCs), as dendritic cells (DCs), the expression of MHC-II and coestimulatory molecules and, thus the CD4 + T cells activation. APCs via

2. Xerostomy, dental caries and periodontal disease in HIV+ patients
We studied xerostomy and its correlation with periodontal and dental cavity diseases in HIV patients, through measurement of salivary flow and through variables such as saliva buffer capacity, salivary pH, periodontal index, MDF index, dental carie risk and risk of periodontal disease. One hundred patients were analyzed. They were distributed into two groups

3. Obtaining molecular markers for prognostic and diagnosis of cutaneous malignant melanoma. / Obtenção de marcadores moleculares para prognóstico e diagnóstico de melanoma cutâneo maligno.
The incidence of malignant skin melanoma (MM) increases around 2,5 a 4% each year in the world. The main risk factors are family history of MM, multiple benign or atypical nevi, and additional factors such as immunossuppression, sun sensibility and UV exposure. Genomic instability is responsible for a collection of mutations that are frequently involved in m

4. In vitro evaluation of the mechanisms of transitory immunosuppression induced by L. amazonensis in healthy individuals low producers of IFN-gamma / Avaliação in vitro dos mecanismos imunossupressores induzid0s por leishmania amazonensis na resposta imune de indivíduos sadios
Estudos anteriores mostraram que indivíduos expostos à Leishmania amazonensis apresentam resposta diferenciada em relação à produção de IFNγ. Aqueles com baixa produção geram uma resposta Th2 e os que apresentam alta produção desta citocina, desde as primeiras horas de infecção, uma resposta Th1. Com o objetivo de avaliar o mecanismo de sup

5. Human immunodeficiency virus/acquired immunodeficiency syndrome and tropical diseases: a Brazilian perspective
The paper summarizes recent findings on the epidemiology and pathogenesis of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/Aids), highlighting the role of co-infections with major tropical diseases. Such co-infections have been studied in the Brazilian context since the beginning of the Aids epidemic and are expected to be more frequen
