Small Myristoylated Protein-3, Identified as a Potential Virulence Factor in Leishmania amazonensis, Proves to be a Protective Antigen against Visceral Leishmaniasis.

In a proteomics approach conducted with, parasite proteins showed either an increase or a decrease in their expression content during extensive in vitro cultivation, and were related to the survival and the infectivity of the parasites, respectively. In the current study, a computational screening was performed to predict virulence factors among these molecules. Three proteins were selected, one of which presented no homology to human proteins. This candidate, namely small myristoylated protein-3 (SMP-3), was cloned, and its recombinant version (rSMP-3) was used to stimulate peripheral blood mononuclear cells (PBMCs) from healthy subjects living in an endemic area of leishmaniasis and from visceral leishmaniasis patients. Results showed high interferon-γ (IFN-γ) production and low levels of interleukin 10 (IL-10) in the cell supernatants. An in vivo experiment was then conducted on BALB/c mice, which were immunized with rSMP-3/saponin and later challenged withpromastigotes. The rSMP-3/saponin combination induced high production of protein-specific IFN-γ, IL-12, and granulocyte-macrophage colony-stimulating factor (GM-CSF) by the spleen cells of the immunized mice. This pattern was associated with protection, which was characterized by a significant reduction in the parasite load in distinct organs of the animals. Altogether, these results have revealed that this new virulence factor is immunogenic in both mice and humans, and have proven its protective efficacy against visceral leishmaniasis in a murine model.

The Combination of Fosfomycin, Metronidazole, and Recombinant Human Granulocyte-Macrophage Colony-Stimulating Factor is Stable in vitro and Has Maintained Antibacterial Activity.

Treatment of secondary peritonitis includes surgery and antimicrobial agents. Antimicrobial agents are often administered intravenously, however, the alternative route intraperitoneal administration could be considered. Investigations must be conducted prior to clinical application. Therefore, we aimed to investigate the combination of fosfomycin, metronidazole, and recombinant human granulocyte-macrophage colony-stimulating factor with regard to its chemical properties and the solution's stability. In addition, the antibacterial effect of the mixed drug solution was compared with the effect of the individual antibacterial agents.

Topically administered rhGM-CSF affects PPARβ expression in the stasis zone.

Using a rat comb thermal damage model, we investigated the effects of topically administered recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) on peroxisome proliferator-activated receptor PPARβ expression. We created bilateral comb scald models on the backs of fifty Sprague-Dawley rats. The left sides of the backs served as the experimental group and the right sides served as the control group. The experimental group received topically applied rhGM-CSF hydrogel and the control group did not. The survival situations of the stasis zones were compared between the experimental and control groups on the 1st, 3rd, 7th, 14th and 21st post-burn days. Tissues from the surviving stasis zones of both groups were collected at different time-points. Reverse transcriptase-polymerase chain reaction (RT-PCR) and western blotting were used to detect the PPARβ mRNA and protein expression levels. Immunohistochemical methods were applied to detect the localization of PPARβ protein expression. The results showed that, first, the tissue viability numbers for the stasis zones of the experimental group were significantly increased compared with those of the control group. Second, RT-PCR revealed that the PPARβ mRNA expression first increased and then gradually declined in both groups. At all time-points, the expression level in the experimental group was increased compared with that in the control group and the highest expression levels were observed in both groups on the 3rd post-burn day. Third, western blot analysis revealed that the PPARβ protein expression in both groups increased after thermal damage and then gradually decreased. PPARβ protein expression in the experimental group was greater than that in the control group, and the highest expression quantities in both groups were observed on the 3rd post-burn day. In conclusion, rhGM-CSF hydrogel effectively promotes the expression of PPARβ, and the hydrogel had a specific protective effect for the stasis zone.

Recombinant prohibitin protein of Leishmania infantum acts as a vaccine candidate and diagnostic marker against visceral leishmaniasis.

Visceral leishmaniasis (VL) represents a serious public health problem, as Leishmania infantum is one of main disease causative agents in the Americas. In a previous immunoproteomic study, the prohibitin (PHB) protein was identified in L. infantum promastigote and amastigote extracts by antibodies in asymptomatic and symptomatic VL dog sera. This protein was found to be highly conserved between different Leishmania spp., but it presented a low identity with amino acid sequences of other organisms. The aim of the present study was to evaluate the cellular response induced by the recombinant PHB (rPHB) protein in BALB/c mice, as well as in PBMCs purified from untreated and treated VL patients, as well as to evaluate its protective efficacy against an infection by L. infantum promastigotes. Our data showed that there was a Th1 cellular response to rPHB, based on high levels of IFN-γ, IL-12, and GM-CSF in the immunized animals, as well as a proliferative response specific to the protein and higher IFN-γ levels induced in PBMCs from individuals who had recovered from the disease. The protection was represented by significant reductions in the parasite load in the animals' spleen, liver, bone marrow, and draining lymph nodes, as compared to results found in the control groups. In addition, an anti-rPHB serology, using a canine and human serological panel, showed a high performance of this protein when diagnosing VL based on high sensitivity and specificity values, as compared to results found for the rA2 antigen and the soluble Leishmania antigenic extract. Our data suggest that PHB has a potential application for the diagnosis of canine and human VL through antibody detection, as well as an application as a vaccine candidate to protect against disease.

Antigenicity, immunogenicity and protective efficacy of a conserved Leishmania hypothetical protein against visceral leishmaniasis.

In this study, a Leishmania hypothetical protein, LiHyS, was evaluated regarding its antigenicity, immunogenicity and protective efficacy against visceral leishmaniasis (VL). Regarding antigenicity, immunoblottings and an enzyme-linked immunosorbent assay using human and canine sera showed high sensitivity and specificity values for the recombinant protein (rLiHyS) in the diagnosis of VL. When evaluating the immunogenicity of LiHyS, which is possibly located in the parasite's flagellar pocket, proliferative assays using peripheral blood mononuclear cells from healthy subjects or VL patients showed a high proliferative index in both individuals, when compared to the results obtained using rA2 or unstimulated cultures. Later, rLiHyS/saponin was inoculated in BALB/c mice, which were then challenged with Leishmania infantum promastigotes. The vaccine induced an interferon-γ, interleukin (IL)-12 and granulocyte-macrophage colony-stimulating factor production, which was maintained after infection and which was associated with high nitrite and IgG2a antibody levels, as well as low IL-4 and IL-10 production. Significant reductions in the parasite load in liver, spleen, bone marrow and draining lymph nodes were found in these animals. In this context, the present study shows that the rLiHyS has the capacity to be evaluated as a diagnostic marker or vaccine candidate against VL.

Colony stimulating factors (CSFs): Complex roles in atherosclerosis.

Colony stimulating factors (CSFs) play a central role in the development and functional maturation of immune cells besides having pleiotropic effects on cells of the vascular wall. The production of CSFs is induced by multiple atherogenic and inflammatory stimuli and their expression levels are often correlated positively with advanced atherosclerotic plaques and adverse cardiovascular events in humans suggesting that CSFs play a critical role in the pathophysiology of atherosclerosis progression. Interestingly, recombinant CSFs as well as anti-CSFs are being increasingly used for diverse clinical indications. However, the effect of these novel therapeutics on atherosclerotic plaque progression is not well understood. Herein, we summarize the currently available literature on the complex role of CSFs in various stages of atherosclerosis and emphasize the necessity for conducting further mechanistic studies in animal models of atherosclerosis as well as the need for evaluating the cardiovascular safety of CSF-based therapies in humans.

Recombinant small glutamine-rich tetratricopeptide repeat-containing protein of Leishmania infantum: Potential vaccine and diagnostic application against visceral leishmaniasis.

Different Leishmania proteins have been evaluated in order to find a potential vaccine candidate or diagnostic marker capable of providing long lasting protection against infection or helping to identify infected mammalian hosts, respectively. However, just few molecules have fulfilled all the requirements to be evaluated. In the current study, we evaluated the prophylactic and diagnostic value against visceral leishmaniasis (VL) of a small glutamine-rich tetratricopeptide repeat-containing (SGT) protein from Leishmania infantum species. In a first step, the immune response elicited by the immunization using the recombinant protein (rSGT) plus saponin was evaluated in BALB/c mice. Immunized animals had a low parasitism in all evaluated organs. They developed a specific Th1 immune response, which was based on protein-specific production of IFN-γ, IL-12 and GM-CSF, and a humoral response dominated by antibodies of the IgG2a isotype. Both CD4and CD8T cells contributed to the IFN-γ production, showing that both T cell subtypes contribute to the resistance against infection. Regarding its value as a diagnostic marker, rSGT showed maximum sensitivity and specificity to serologically identify L. infantum-infected dog and human sera. No cross-reactivity with sera from humans or dogs that had other diseases was found. Although further studies are necessary to validate these findings, data showed here suggest immunogenicity of rSGT and its protective effect against murine VL, as well as its potential for the serodiagnosis of human and canine VL.

In vitro infectivity of oncolytic Newcastle Disease Virus: Correlation between plaque and fluorescent focus assays.

Newcastle Disease Virus (NDV) is an avian paramyxovirus that has no significant pathogenicity in humans. Cancer cells with impaired immune defense mechanisms are susceptible to infection and lysis by NDV. A recombinant construct of a lentogenic form of NDV (rNDV) containing an insertion of granulocyte macrophage colony stimulating factor (GMCSF) transgene was earlier reported and shown to have acceptably low avian pathogenicity as well as oncolytic potential. Reliable measurement of infectious titer is key to determining the effectiveness of virus preparations to infect and lyse cells. We report here a comparative evaluation of two infectious titer assays as applied to rNDV: plaque assay and fluorescent focus assay (FFA). Optimization of assay conditions for both titer methods has produced concordant results spanning several orders of magnitude. While plaque formation is the gold standard measure of virus titer, FFA provides higher throughput and faster turn-around. FFA has been further evaluated on two different instrument platforms, for automated versus manual foci recognition and counting, with equivalent results. These results point to amenability of FFA to transfer between different laboratories and analysts, without introducing significant subjectivity in data analysis.
