Abstract
Paracoccidioidomycosis (PCM) is a human systemic granulomatous mycosis caused by thermodimorphic fungi from Paracoccidioides genus. The disease is prevalent in Latin America and triggers a serious clinical condition. Consequently, rapid diagnosis and treatment are crucial to prevent progression of the disease, which can result in death. Currently, there are several established methods for PCM diagnosis. However, many of these tests still present challenges in terms of cost, accessibility and efficiency. In this scenario, gold nanoparticles represent a promising alternative since they have particular optical and electronic properties, which allow its use for biomolecules detection. This review will briefly present techniques available for PCM diagnosis and the perspectives of implementation of gold nanoparticles for diagnosis of this mycosis.

Abstract
INTRODUCTION Paracoccidioidomycosis (PCM) is the most important systemic mycosis in South America. Central nervous system involvement is potentially fatal and can occur in 12.5% of cases. This paper aims to contribute to the literature describing eight cases of neuroparacoccidioidomycosis (NPMC) and compare their characteristics with patients without neurological involvement, to identify unique characteristics of NPCM. METHODS A cohort of 213 PCM cases was evaluated at the Infectious Diseases Clinic of the University Hospital, Federal University of Minas Gerais, Brazil, from October 1976 to August 2008. Epidemiological, clinical, laboratory, therapeutic and follow-up data were registered. RESULTS Eight patients presented NPCM. The observed NPCM prevalence was 3.8%. One patient presented the subacute form of PCM and the other seven presented the chronic form of the disease. The parenchymatous form of NPCM occurred in all patients. 60% of the patients who proceeded from the north/ northeast region of Minas Gerais State developed NPCM. The neurological involvement of a mother and her son was observed. NPCM patients exhibited demographical and clinical profiles similar to what is described in the literature. When NPCM cases were compared to PCM patients, there were differences in relation to origin and positive PCM family history. CONCLUSIONS The results corroborate the clinical view that the neurological findings are extremely important in the evaluation of PCM patients. Despite the limitations of this study, the differences in relation to patient's origins and family history point to the need of further studies to determine the susceptibility factors involved in the neurological compromise.

Abstract
Immunoepidemiological studies from endemic areas have revealed age-dependent resistance correlation with increased level of IgE and decreased level of IgG4 antibodies in responses to schistosomes' soluble worm antigen. However, there have been limited studies on analyses of major antigens that provoke IgE and IgG4 immune response during chronic stage of schistosomiasis. In this study, for the first time, immunoproteomics approach has been applied to identify S. japonicum worm antigens in liquid fractions that are recognized by IgE and IgG4 antibody using plasma from chronically infected population. ProteomeLabPF 2D fractionated 1-D and 2-D fractions of SWA antigens were screened using pooled high IgE/IgG4 reactive plasma samples by dot-blot technique. In 1-D fractions, IgE isotype was detected by fewer antigenic fractions (43.2%). The most recognized isotype was IgG3 (79.5%) followed by IgG1 (75.0%) and IgG4 (61.4%). Liquid chromatography MS/MS protein sequencing of reactive 2-D fractions revealed 18 proteins that were identified, characterized and gene ontology categories determined. 2-D fractions containing proteins such as zinc finger, RanBP2-type, domain-containing protein were strongly recognized by IgE and moderately by IgG4 whereas fractions containing proteins such as ubiquitin-conjugating enzyme and cytosolic II 5'-nucleotidase strongly recognizing by IgG subclasses (IgG1, IgG3 and IgG4) but not IgE. By this study, a simple and reproducible proteomic method has been established to identify major immunoreactive S. japonicum antigens. It is anticipated that this will stimulate further research on the immunogenicity and protective potential of proteins identified as well as discovery of novel compounds that have therapeutic importance.

Abstract
Este trabalho é o primeiro a realizar uma revisão sistemática dos casos de neuroparacoccidioidomicose disponíveis na literatura. Foram encontrados 257 casos em 81 trabalhos pesquisados pelo MEDLINE e LILACS, com maior número de publicações após as décadas de 1970-1980. Aproximadamente, 93% dos pacientes eram homens, principalmente lavradores, com idade média de 43 anos. O quadro caracterizou-se por sintomatologia motora ou de hipertensão intracraniana. A forma crônica pseudotumoral predominou. O período médio de evolução foi de 4,9 meses. As lesões foram principalmente supratentoriais (66,8%), localizando-se nos lobos frontais e parietais. A biópsia determinou o diagnóstico em 57,2% dos casos e utilizaram-se métodos de neuroimagem em 64,6% deles. Houve grande associação com a forma pulmonar da doença (59,1%). A mortalidade foi de 44,1% e 50,1% dos sobreviventes evoluíram com sequelas, principalmente motoras. Assim, deve-se considerar a neuroparacoccidioidomicose no diagnóstico diferencial dos processos expansivos e meningoencefalíticos do sistema nervoso central para se estabelecer tratamento precoce e evitar seqüelas incapacitantes.

Abstract
Paracoccidioidomycosis (PCM) is the most common systemic mycosis in Latin America. A major problem in the management of PCM is to determine the best time to discontinue therapy due to the high relapse rate among patients. Soluble TNF receptors (sTNF-R) levels and chemokines are associated with disease activity in several infectious, inflammatory and autoimmune disorders. The aim of the present work was to evaluate levels of sTNF-R1, sTNF-R2 and chemokines in serum of patients with adult type of PCM, before and after antifungal therapy, and to correlate those levels to disease activity. Concentrations of sTNF-R1, sTNF-R2 and CXCL9 were higher in untreated patients and decreased progressively with treatment. The serum marker with the best accuracy to discriminate PCM cases from controls was sTNF-R2. sTNF-R1 did not drop to control levels before 36 months of treatment. CCL2 and CCL3 levels were low at baseline in PCM patients, raised significantly after 12 months of treatment and diminished thereafter. CCL24 levels were higher after 36 months of antifungal therapy in PCM patients. CCL11 levels were not statistically different from control subjects. sTNF-R1, sTNF-R2 and CXCL9 may be useful as laboratory parameters to assess disease activity in PCM patients.

Abstract
Paracoccidioides brasiliensis is the fungus agent of paracoccidioidomycosis, a chronic systemic disease prevalent in Latin America. The aim of the present work was to evaluate the protection elicited by the immunization of BALB/c mice with radioattenuated yeast cells of P. brasiliensis. The immunization promoted a long lasting protection against highly infective yeast forms of P. brasiliensis. A 99.5% decrease in CFUs recovery was verified 90 days post challenge. At the same time the levels of IgG2a and IFN-gamma were high while a very low production of IL-10 and IL-5 was verified, suggesting that a Th1 pattern was dominant. This work shows the potential of radioattenuated yeast cells for the development of vaccines against fungi infections.

Abstract
Memory T cell populations in patients with paracoccidioidomycosis (PCM) were analyzed before and after chemotherapy treatment. Peripheral blood mononuclear cells (PBMC) collected from patients infected by Paracoccidioides brasiliensis or from non-infected individuals were stimulated in vitro with either membrane and extra-cellular antigens (MEXO) or yeast cell antigen preparation (PbAg) of P. brasiliensis. An increase in the level of CD4(+) memory T cells was determined in PBMC from PCM patients before (NT) and after treatment (TR) and in those with PCM relapsed (RE) compared to that from non-infected controls (NINF). The CD8(+) memory T cells were increased in PBMC from RE patients stimulated with MEXO, but not in NT or TR. The distribution of memory B cells did not differ between NT and TR patients, while a significant elevation was determined in RE patients and higher antibody levels were also detected. The cytokine analysis showed low production of IFN-gamma by cells from RE patients compared with NT or TR patients. In contrast, high production of IL-4 was detected in NT and RE patients, and moderate levels were produced by RE patients. These results suggest that IFN-gamma production may participate in the maintenance of immunological memory in the acquired protection against P. brasiliensis infection and this data can contribute to future development of successful treatment of PCM to avoid relapsing.

Abstract
Allelic variants of cytokine genes seem to be involved in mechanisms of resistance or susceptibility to several diseases. The aim of this study was to investigate the frequency of genotypes with the tumor necrosis factor-alpha TNF-alpha gene polymorphism G/A at position -308 and the IL-10 gene polymorphism G/A at position -1082, and to verify a possible association of these polymorphisms with paracoccidioidomycosis (PCM) caused by Paracoccidioides brasiliensis. Genotyping was performed by allele-specific polymerase chain reaction (ASPCR) and restriction fragment length polymorphism (RFLP) on genomic DNA isolated of granulocytes from 54 PCM patients and 31 noninfected individuals. The analysis of SNP at position -1082 IL-10 showed a high frequency of GA genotype in both patients and controls (51% and 55%, respectively), while the allelic frequency showed 54% of G allele in the patients and 66% of A allele in the controls. The GG genotype was more frequent in patients (85%) and controls (68%) when we analyze the SNP at position -308 of TNF-alpha gene. Otherwise, 91% of PCM patients and 84% of noninfected individuals carried the G allele in -308 TNF-alpha SNP. Stimulation of cells from individuals with PCM phenotyped as A+ (GA or AA genotypes) presented elevation of TNF-alpha producing cells when compared with IL-10-producer cells. These findings reinforce the critical role of IL-10 and TNF-alpha in the paracoccidioidomycosis and can strongly suggest that the genetic screening of the -308G/A and -1082G/A polymorphisms may be a valid tool for identification of subjects needing a more appropriate therapy.
