The percentage of T-cell subpopulations in PBL from infected mice did not differ significantly from those of normal mice. Immunoregulation of ...
THESIS. The inhibitory effect of MK886 on the inflammatory process caused by Paracoccidioidomycosis brasiliensis infection in genetically selected mice. Correspondence to. Thesis: H. A. Balderramas submitted this thesis for his Masters in Tropical Diseases at the Botucatu Medical School, São Paulo State University, UNESP, Botucatu, São Paulo State, Brazil, 2008.. Advisor: Professor Silvio Luis de Oliveira. ABSTRACT. Leukotrienes are classic inflammatory response mediators considered chemotactic agents and microbicidal activity regulators in cells of the innate immune system, playing a protective role against different infectious agents. In this study, we investigated the involvement of leukotrienes in the course of murine paracoccidioidomycosis based on the following immunologic parameters: cell influx, mieloperoxydase activity, NO production, cytokine production, and fungal recovery in lungs of mice selected according to the intensity of their low (AIRmin) and high (AIRmax) acute inflammatory ...
Paracoccidioidomycosis (PCM) is an endemic systemic mycosis in Latin America, with the best prevalence in Brazil, Colombia, and Venezuela. most significant systemic granulomatous illnesses in Latin America (Taborda et al., 2015). PCM is certainly widespread in Brazil especially, affecting generally rural employees (Restrepo, 1985; Taborda and Travassos, 2012b). In Brazil, 1 approximately,853 (51.2%) of 3,583 confirmed deaths due to systemic mycoses from 1996 to 2006 were caused by PCM (Prado et al., 2009). Phylogenetic analyses have revealed that this clinically relevant species include (Teixeira et al., 2013). Acquisition of spp. follows the inhalation of conidia, which are deposited into the lower respiratory tract. These propagules subsequently undergo morphogenic transformation into yeast forms, which constitute the pathogenic morphology EM9 in tissues (Taborda et al., 2015). PCM has two main clinical forms that are predicated upon the immunological status of the infected host. Within weeks ...
We used the micro- and macroimmunodiffusion test for the qualitative and quantitative measurement of anti - P. brasiliensis antibodies in serum of patients with paracoccidioidomycosis. All 103 paracoccidioidomycosis sera (100%) were positive in the micro test versus 87% positivity index in the macrotest. All 83 control sera from patients with other diseases were negative in both tests. Titers of the positive sera tended to be higher in the microtest, which revealed sharper and easier to read precipiting bands. Microimmunodiffusion is simple to be performed, requires a minimum amount of reagents and allows the simultaneous testing of 102 sera. It may replace the macrotest specially in laboratories dealing with great serologic routine ...

Paracoccidioidomycosis should be differentiated from other opportunistic diseases in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients who live in Latin America. Laboratory investigation can begin with serological tests, which are rapid and efficient. In the present study, double immunodiffusion (DID), counterimmunoelectrophoresis (CIEP) and an enzyme linked immunosorbent assay (ELISA) tests were assessed for the detection of anti-Paracoccidioides brasiliensis antibodies in 40 patients coinfected with HIV. The results were compared to those obtained for 75 non-HIV-infected patients with endemic paracoccidioidomycosis. Anti-P. brasiliensis antibodies were detected in 65% (DID), 79% (CIEP) and 95% (ELISA) of the patients with HIV/AIDS, significantly lower rates than those detected in cases of endemic paracoccidioidomycosis, which were 89%, 99% and 100%, respectively. The reactive sera of HIV-infected patients also showed lower anti-P. brasiliensis antibody ...
Background and purpose:The present study reports on the preparation and testing of a sustained delivery system for the immunomodulatory peptide P10 aimed at reducing the in vivo degradation of the peptide and the amount required to elicit a protective immune response against paracoccidioidomycosis.Experimental approach:BALB/c mice were infected with the yeast Paracoccidioides brasiliensis to mimic the chronic form of paracoccidioidomycosis. the animals were treated daily with sulfamethoxazole/trimethoprim alone or combined with peptide P10, either emulsified in Freunds adjuvant or entrapped in poly(lactic acid-glycolic acid) (PLGA) nanoparticles at different concentrations (1 mu g, 5 mu g, 10 mu g, 20 mu g or 40 mu g center dot 50 mu L-1). Therapeutic efficacy was assessed as fungal burden in tissues and the immune response by quantitative determination of cytokines.Key results:Animals given combined chemotherapy and P10 nanotherapy presented a marked reduction of fungal load in the lungs, ...
Deaths caused by systemic mycoses such as paracoccidioidomycosis, cryptococcosis, histoplasmosis, candidiasis, aspergillosis, coccidioidomycosis and zygomycosis amounted to 3,583 between 1996-2006 in Brazil. When analysed as the underlying cause of death, paracoccidioidomycosis represented the most important cause of deaths among systemic mycoses (~ 51.2%). When considering AIDS as the underlying cause of death and the systemic mycoses as associated conditions, cryptococcosis (50.9%) appeared at the top of the list, followed by candidiasis (30.2%), histoplasmosis (10.1%) and others. This mortality analysis is useful in understanding the real situation of systemic mycoses in Brazil, since there is no mandatory notification of patients diagnosed with systemic mycoses in the official health system ...
The 43-kDa glycoprotein of may be the major diagnostic antigen of paracoccidioidomycosis, the prevalent systemic mycosis of Latin America. challenge by virulent antigens, whether associated with polyclonal B-cell activation or not, does not induce protection (26). Rabbit Polyclonal to ACOT2. Considering the immunodominant cellular immune response elicited by gp43, which may halt the progression of the infection, along with a locally effective but generally unprotective antibody response to this antigen, we aimed in the present investigation at determining the epitopes mediating these immune responses and at selecting those that could MP470 be used in vaccination trials. We show here that a 15-amino-acid peptide (P10) contained in gp43 is responsible for glycoprotein-mediated T-cell activation and protection against PCM in BALB/c mice without eliciting antibodies directed against the native antigen. MATERIALS AND METHODS Purification of gp43 from B-339, originally obtained from A. ...
Primary infection, although poorly understood due to lack of data, is thought to occur through inhalation of the conidia through the respiratory tract, after inhaling fungal conidia produced by the mycelial form of P. brasiliensis.[10][16] This occurs predominantly in childhood and young adulthood, after exposure to agricultural activity.[9] Infection may occur through direct skin inoculation, although this is rare.[11]. After inhalation into the alveoli, there is rapid multiplication of the organism in the lung tissue, sometimes spreading via the venous and lymphatic systems.[10] Approximately 2% of people develop clinical features after the initial asymptomatic infection.[11]. The type of immune response determines the clinical manifestation of the infection, with children and HIV co-infected individuals most commonly developing the acute/subacute disseminated disease.[10] Most of those infected develop a Type 1 T-cell (Th1) mediated immune response, resulting in alveolitis and compact ...
Results: Patients in cases 1 and 2 both reported indisposition, asthenia, nausea, hyperpigmentation of the skin, hypotension, and weight loss. Complementary exams confirmed PAI due to PCM. Case 1 was serologically diagnosed. In contrast, the definitive diagnosis of case 2 was only reached by computed tomography (CT)-guided adrenal biopsy after negative serologies for PCM. Case 3, with diabetes mellitus, had a history of asthenia, nausea and weight loss after persistent sinusitis. Initially, serologic results were negative for PCM and the patients CT-guided biopsy resulted in insufficient tissue to obtain a definitive diagnosis. Contrary to the initial hypothesis of invasive aspergillosis, since the only etiological evidence for the patients clinical condition were positive serologies for Aspergillus fumigatus, histopathologic examination of the specimen provided by a left adrenalectomy finally confirmed PCM as the etiology for PAI in this case as well ...

C3-bearing immune complexes and C3 activation products were detected by using two monoclonal antibodies, one specific for a neoantigenic determinant on C3c and the other for C3d. To quantitate immune complexes, the anti-C3c or anti-C3d antibodies were fixed to microtiter plates and reacted with test plasma. The binding of C3-bearing immune complexes in this plasma was then measured with radioisotope- or enzyme-labeled anti-human IgG. To test for C3 breakdown products, solid-phase monoclonal antibody to the C3d neoantigen was reacted with EDTA-plasma samples, and fixed iC3b or C3d was measured with a polyclonal anti-C3 antibody. Patients with autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and Sjogrens syndrome, and paracoccidioidomycosis were found to contain immune complexes bearing C3b/iC3b or C3d. In most conditions, there were more C3d-containing immune complexes than C3b/iC3b. Although CR1 (C3b receptors) rapidly converted immune complex-bound iC3b to ...
American cutaneous leishmaniasis (ACL) should be differentiated from traumatic ulcers, venous ulcers, tropical ulcer, lower limb ulcers due to sickle cell anemia, pyodermatitis, paracoccidioidomycosis, syphilis, cutaneous neoplasms, among others.1 Histopathology may be suggestive, but it is rarely specific enough to make the diagnosis without identification of the amastigote forms of the parasite.2 Among the non-specific alterations to the histopathological examination, pseudoepitheliomatous hyperplasia (PEH) presents as a challenge, especially in the differential diagnosis with squamous cell carcinoma (SCC).

14-3-3 proteins comprise a family of eukaryotic multifunctional proteins involved in several cellular processes. The Pb14-3-3 of Paracoccidioides brasiliensis seems to play an important role in the Paracoccidioides-host interaction. Paracoccidioides brasiliensis is an etiological agent of paracoccidioidomycosis, which is a systemic mycosis that is endemic in Latin America. In the initial steps of the infection, Paracoccidioides spp. synthetizes adhesins that allow it to adhere and invade host cells. Therefore, the aim of this work was to perform a functional analysis of Pb14-3-3 using Saccharomyces cerevisiae as a model. The functional analysis of Pb14-3-3 was performed in S. cerevisiae, and it was found that Pb14-3-3 partially complemented S. cerevisiae proteins Bmh1p and Bmh2p, which are recognized as two yeast 14-3-3 homologues. When we evaluated the adhesion profile of S. cerevisiae transformants, Pb14-3-3 acted as an adhesin in S. cerevisiae; however, Bmh1p did not show this function. The influence

N2 - Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the dimorphic fungi Paracoccidioides spp. The duration of antifungal treatment ranges from months to years and relapses may nevertheless occur despite protracted therapy. Thus, there remains an urgent need for new therapeutic options. Miltefosine (MLT), an analogue of alkylphospholipids, has antifungal activity against species of yeast and filamentous fungi. The aim of this study was to evaluate the antifungal effects of MLT on the yeast forms of Paracoccidioides brasiliensis and Paracoccidioides lutzii. MLT demonstrated inhibitory activity from 0.12 to 1 µg/mL, which was similar to amphotericin B or the combination ...
Paracoccidioides brasiliensis is the causative agent of a true systemic (endemic) mycosis called paracoccidioidomycosis. The spectrum of the disease is wide, varying from an asymptomatic infection verified by the skin test to a subclinical, symptomatic or chronic infection. Diagnosis of paracoccidioidomycosis is often difficult. The infection may become apparent several years after exposure to Paracoccidioides brasiliensis, suggesting the possibility of a long latent period. The infection is presumably acquired via inhalation of the conidia, followed by primary infection of the lungs. The degree of pathogenicity may vary and appears strain-dependent. An exocellular serine-thiol proteinase enzyme is a significant virulence factor of the fungus for tissue invasion. In addition to the primary pulmonary form of the disease, acute pulmonary, chronic pulmonary, and disseminated forms may also be observed. In cases of disseminated paracoccidioidomycosis, reticuloendothelial system, skin and mucous ...
The major aim of this study was to evaluate the possible role of NK cells in the initial immunological response against P. brasiliensis. Among the few studies about this issue, the study carried out by Peraçoli et al. (13) showed more NK cells in the peripheral blood of PCM patients, although exhibiting a diminished cytotoxic activity. Our data partially confirm these data, given that we observed that NK cells from patients with active disease did exhibit a decreased cytotoxic response against target cells. In relation to the number of CD56+ cells, we found no differences between PCM patients and healthy individuals. Additionally, we observed that after the treatment, the cytotoxic capability of NK cells from patients was similar to that observed in the control group. These data indicate that during the development of the disease, it is possible that the acquired immunological response interfere with the activation of NK cells. PCM patients with active disease are characterized by the ...
Background. Paracoccidioides brasiliensis is a facultative intracellular dimorphic fungus that causes paracoccidioidomycosis (PCM), the most important deep mycosis in Latin America. Only a small percentage of individuals infected by P. brasiliensis develop clinical PCM, possibly in part because of genetically determined interindividual variability of host immunity. However, no primary immunodeficiency has ever been associated with PCM.. Methods. We describe the first patient, to our knowledge, with PCM and a well-defined primary immunodeficiency in the β1 subunit of the interleukin (IL)-12/IL-23 receptor, a disorder previously shown to be specifically associated with impaired interferon (IFN)-γ production, mycobacteriosis, and salmonellosis.. Results. Our patient had a childhood history of bacille Calmette-Guùrin disease and nontyphoid salmonellosis and, at the age of 20 years, presented to our clinic with a disseminated (acute) form of PCM. He responded well to antifungal treatment and is ...

The fungal pathogen Paracoccidioides brasiliensis produces a melanin-like pigment in the presence of l-DOPA in vitro. We investigated whether melanization affected yeast uptake by alveolar and peritoneal macrophages, the intracellular resistance of fungal cells and their susceptibility to antifungal drugs. The interactions of melanized and nonmelanized P. brasiliensis with murine primary macrophages and J774.16 and MH-S macrophage-like cell lines were investigated. Melanized yeast cells were poorly phagocytosed by the cells even in the presence of complement. Melanization caused significant interference with the binding of cell wall components to lectin receptors on macrophages. Melanized cells were also more resistant than nonmelanized cells to the antifungal activity of murine macrophages. No difference in the susceptibilities of melanized and nonmelanized P. brasiliensis to antifungal drugs was observed using the minimum inhibitory concentration (MIC) method. However killing assays showed ...
Abstract Sera of patients with paracoccidioidomycosis contained IgG-, IgA-, and IgM-specific antibodies to a 43 kDa antigen contained in the filtrate of a culture of Paracoccidioides brasiliensis. IgG- and IgA-specific antibodies were present in all observed patients. The IgM response was more frequent in acute cases, and the mean titers of IgG- and IgM-specific antibodies were higher in the acute forms. By the fourth month of chemotherapy, there was a decay of IgG, IgA, and IgM antibody titers to this antigen in acute cases, correlating with clinical improvement. The detection of IgG and IgA antibodies and the sequential determination of antibodies to the 43 kDa glycoprotein may be useful tools for serodiagnosis and evaluation of therapeutic efficacy.
Sera from patients with paracoccidioidomycosis (PCM), histoplasmosis (HP), or Jorge Lobos disease (JL) were titrated against purified gp43 from Paracoccidioides brasiliensis by using both enzyme-linked immunosorbent assay (ELISA) and immunoprecipitation (IPP) reactions with 125I-labeled antigens. In IPP, PCM sera and other sera could be distinguished on the basis of serum titers, whereas in ELISA, 53% of the HP sera and 29% of the JL sera reacted similarly to the PCM sera. To investigate the possible role of the carbohydrate epitopes in these reactions, we compared the reactivities of sera from several patients with native and deglycosylated gp43. Competition experiments were carried out with monosaccharides as inhibitors. The results suggest that greater than 85% of the reactions of the PCM sera with gp43 involved peptide epitopes. Cross-reactions with HP and JL sera in ELISA were predominantly attributed to periodate-sensitive carbohydrate epitopes containing galactosyl residues. HP and JL ...
The basis for virulence in Paracoccidioides brasiliensis is not completely understood. There is a consensus that the sequencial in vitro subcultivation of P. brasiliensis leads to loss of its pathogenicity, which can be reverted by reisolation from animal passage. Attention to morphological and biochemical properties that are regained or demonstrated after animal passage may provide new insights into factors related to the pathogenicity and virulence of P. brasiliensis. We evaluated morphological characters: the percentage of budding cells, number of buds by cell and the diameter of 100 mother cells of yeast-like cells of 30 P. brasiliensis isolates, before and after animal passage. The isolates were obtained from patients with different clinical forms of paracoccidioidomycosis (PCM): acute form (group A, n=15) and chronic form (group C, n=15). The measurement of the yeast cell sizes was carried out with the aid of an Olympus CBB microscope coupled with a micrometer disc. We measured the major ...
Since Paracoccidioides brasiliensis and Histoplasma capsulatum are known to be present in similar environments, there have been many epidemiologic investigations regarding the prevalences of these two organisms. However, cross-reactivity can occur in paracoccidioidin and histoplasmin skin tests, and this usually results in the overestimation of the prevalence of P. brasiliensis.The prevalence of infection with P. brasiliensis was evaluated in a cross-sectional study of 298 asymptomatic school children in the Brazilian Amazon region (Mato Grosso State). In this investigation, the reactivity of children to two different P. brasiliensis antigen preparations, paracoccidioidin and a purified 43-kD glycoprotein (gp43), was compared with or without the co-administration of histoplasmin. In the group of individuals receiving paracoccidioidin who had a positive histoplasmin skin test result, the prevalence of exposure to P. brasiliensis was 44% (16 of 36). This reactivity to P. brasiliensis was significantly

Paracoccidioidomycosis (PCM) occurs in two distinct forms, the acute or juvenile form (JF), and the chronic or adult form (AF). To clarify the basis of this dichotomy, specific IgG subclasses, IgA and IgE anti-gp43 were measured by enzyme-linked immunosorbent assay, in patients with different forms of PCM. Serum levels of tumor necrosis factor-alpha, interleukin (IL)-6, IL-8, macrophage inflammatory protein (MIP)-1alpha and transforming growth factor (TGF)-beta were also quantified. We show here that JF patients have significantly higher titers of IgE antibodies against gp43, an immunodominant antigen specific for Paracoccidioides brasiliensis, than do patients with the unifocal adult form (UF-AF, isolated lesions). Patients with the multifocal adult form (MF-AF, lesions in more than one organ) also produced elevated levels of anti-P. brasiliensis IgE. Furthermore, specific IgE levels were correlated with IgG4, IgA and eosinophilia. Patients with JF showed eosinophilia and increased levels of ...

The P. brasiliensis virulence orthologs were placed in groups, based either on their functional or structural characteristics, such as: metabolism-, cell wall-, detoxification-related genes, secreted factors and other determinants (Navarro-Garcia et al., 2001). In this review, we examined specific gene products that were assigned as virulence factors by a molecular genetic approach (molecular Kochs postulates).. METABOLISM-RELATED GENES. P. brasiliensis, a facultative intracellular pathogen, is able to survive and replicate within the phagosome of nonactivated murine and human macrophages (Brummer et al., 1988a,b, 1989, 1990; Moscardi-Bacchi et al., 1994; Gonzalez et al., 2000). Thus, this fungus may have evolved mechanisms that counteract the metabolic constraints imposed by phagocytic cells. The phagosome is believed to be a poor source of complex carbon, such as carbohydrates. Instead, intracellular pathogens may find only two-carbon (C2) compounds for energy production such as acetate, a ...

Resumo: A paracoccidioidomicose (PCM), causada pelo fungo dimórfico Paracoccidioides brasiliensis (Pb), é a micose sistêmica de maior incidência no Brasil. Estudos anteriores demonstraram que a resistência ou suscetibilidade a essa infecção podem ser associadas, respectivamente, a padrões de resposta Th1 ou Th2. Recentemente, foram descritas novas subpopulações de linfócitos T, dentre elas as células Th17, que tem se mostrado importantes na proteção contra infecções fúngicas, mas cujo papel ainda não foi estudado na PCM humana. A diferenciação de células T CD4+ é modulada após o reconhecimento do patógeno por células dendríticas (DCs) por meio de vários receptores de reconhecimento padrão (PRRs), os quais modulam a diferenciação de células Th1, Th2 e Th17. Neste trabalho investigamos o papel dos receptores TLR2, TLR4 e Dectina-1 no reconhecimento de células leveduriformes de P. brasiliensis (Pb) por DCs derivadas de monócitos, assim como, a capacidade dessas DCs ...
