Project description:As a vector-borne disease, leishmaniasis is caused by a parasitic protozoans of leishmania genus and transmitted by female Phlebotomine sandflies. Depending on the body location where immotile form of the parasite namely amastigote is proliferated, three main clinical forms as cutaneous, muco-cutaneous and visceral leishmaniases are defined. While manifestation of cutaneous leishmaniasis is skin lesions on the exposed part of the body, enlarged lymph nodes, spleen or liver along with fever, fatigue and weight loss are the symptoms of visceral leishmaniasis. The most dangerous form is visceral leishmaniasis since it may end up with fatalities if patients are not treated. The purpose of this study was to investigate the difference between the protein expression profiles of leishmania isolates obtained from visceral and cutaneous leishmaniasis patients. To compare two sample groups to each other genetically, L.infantum was chosen since it causes both visceral and cutaneous leishmaniasis. Additionally, another sample group as cutaneous leishmaniasis caused by L.tropica was included to make the comparison both intra- and interspecies level. For protein profiling, both gel-based and gel-free proteomic approaches were carried out. In brief, a total of 15 samples, 5 from each group, were separated on pI 3-10 2D-PAGE gel. Additionally, 9 of those 15 samples, 3 from each group, were analyzed according to qualitative shotgun proteomics method and differential proteins were determined by drawing venn diagram.

Project description:We evaluated the trancriptome of primary cutaneous leisions caused by infection with Leishmania braziliensis. mRNA-seq technique was used to study the trancriptome of both host and parasite. A total of 10 samples was obtained from primary skin ulcers of two extreme clinical forms of American tegumentary leishmaniasis: (i) individuals that after antimonial treatment cured completely (localized cutaneous leishmaniasis - LCL, n=5) and (ii) individuals that developed mucosal lesions in naso and oropharynx areas long after initial healing of the cutaneous lesion (mucosal leishmaniasis - ML, n=5). The sequencing generated an average of 13+ 5 million reads per samples. The reads were aligned to Homo sapiens (USCS - hg19) and to Leishmania braziliensis (Wellcome Trust Sanger Institute - V2_29072008) genomes. Approximately, 15,000 human genes could be detected in the samples. Low amount of L. braziliensis reads did not allow the evaluation of parasite gene expression. LCL and ML samples showed different patterns of gene expression, indicating a more robust immune response in LCL individuals. In summary, this study demonstrated that next-generation sequencing can be used for identification of potentially important biological pathways and drug targets in the host-response to L. braziliensis infection and for characterization of a gene expression signature that could be used to predict the disease outcome. Moreover, we also showed the ability of this technique in, simultaneously, sequence host and pathogen mRNA. Examination of 10 fragments of cutaneous lesions: 5 from localized cutaneous leishmaniasis patients and 5 from mucosal leishmaniasis patients.

Project description:The present study deals with functional interactions of cutaneous and brain-metastasizing human melanoma cells with brain-derived molecules. In this study we employed the unique melanoma xenograft model developed by Izraely and described in Int J Cancer. 2011 Oct 25. doi: 10.1002/ijc.27324. The present study aims to determine if brain-derived soluble factors regulate malignancy-associated functions of cutaneous and brain-metastasizing melanoma cells and identify which functions are regulated by such factors. The working hypothesis of this study is that the interactions between the brain microenvironment and melanoma cells determine metastasis formation at this organ site. The aim of the study was to evaluate the contribution of such interactions to the formation of brain metastasis in nude mice xenografted with human melanoma cells. An insight into these interactions is an essential pre-requisite for the development of effective targeted therapy for melanoma brain metastasis. We assessed the effects of soluble factors present in supernatants of short-term cultures of normal mouse brain (referred here after as brain-derived soluble factors) on several characteristics linked to melanoma brain metastasis. It was found that brain-derived soluble factors affect differentially cutaneous and brain-metastasizing melanoma cells variants in-vitro. Such factors enhanced the viability of cutaneous melanoma cells but caused an S phase arrest followed by apoptosis of brain-metastasizing cells. Brain-derived soluble factors enhanced migration of melanoma cells metastasizing to the brain, but did not affect the migration of the cutaneous variants. Such factors up-regulated the expression of the chemokine receptor CCR4 in both cutaneous and brain metastasizing melanoma cells. It is not unlikely that CCR4 ligands expressed in the brain interact with the CCR4-expressing melanoma cells thereby directing them to the brain. Brain-derived soluble factors enhanced the transmigration, across human brain endothelial cells of cutaneous but not of brain metastasizing melanoma variants. This activity could promote the capacity of the cutaneous cells to metastasize to the brain. 4 Samples (arrays) were analyzed. There is 1 replicate for each variant and each treatment. We generated pairwise comparisons between cutaneous and brain metastatic variants of the same genetic background, using Partek Genomics Suite, in the three melanoma models. Genes with p≤5% and a fold-change difference of ≥2 or <-2 were selected.

Project description:To analyze the pathogenic mechanism of the autoinflammatory skin syndromes caused by an NLRP1 mutation, we sought to generate Nlrp1b mutation knock-in mice mice as a mouse model of cutaneous autoinflammatory lesions due to NLRP1 mutants, and examine the expression of proteins, such as cytokines, and the mRNA expression profile, including inflammasome-related genes in the model lesions.
