1. Dengue serotype-specific immune response in Aedes aegypti and Aedes albopictus
BACKGROUND Dengue viruses (DENV) are considered one of the most important emerging pathogens and dengue disease is a global health threat. The geographic expansion of dengue viruses has led to co-circulation of all four dengue serotypes making it imperative that new DENV control strategies be devised. OBJECTIVES Here we characterize dengue serotype-specifi

2. Feeding habits of mosquitoes (Diptera: Culicidae) in an area of sylvatic transmission of yellow fever in the state of São Paulo, Brazil
AbstractBackground The reintroduction of sylvatic yellow fever in the state of São Paulo after about six decades was confirmed in the Northwestern region in 2000, where in 2008 there also occurred an important epizootic. The purpose of this study was to investigate the feeding habits of culicids potentially involved in the sylvatic transmission of the virus

3. Desenvolvimento e avaliação imunológica de Nanotubos de Carbono funcionalizados com a proteína de envelope de Dengue virus 3
In terms of epidemiologic impact, Dengue (DENV) infections represent the most important infectious disease in Brazil. Consequently, the development of an efficient vaccine is considered a high priority. Due to this fact, many studies are being developed towards this goal, but no vaccine is currently available to the population. Carbon Nanotubes (CNT) have be

4. Identificação de um fator do hospedeiro, RPS5A, envolvido na interação com a proteína de movimento (MP) de geminivírus / Identification of movement protein MP-intaracting host facotrs
The movement protein MP from bipartite geminivirus (begomovirus) facilitates the cell-to-cell and long-distance transport of viral DNA in addition to affecting viral pathogenicity. To identify host factors that interact with MP, initially a cDNA library prepared from CaLCuV (Cabbage leaf curl virus)-infected Arabidopsis leaf mRNA was generated in a pEXPAD502

5. Detecção do vírus da leprose dos citros nos tecidos da planta infectada e do ácaro vetor Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae) / Detection of Citrus leprosis virus C (CiLV-C) in the tissues of infected plants and of mite vector Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae)
Citrus leprosis is one of the most important diseases in the Brazilian citrus production due to the wide occurrence in orchards and also to the high costs involved in the chemical control of the mite vector. The disease affects the plant production and longevity and it is characterized by localized chlorotic and/or necrotic spots on the leaves, stems and fru

6. Differentially expressed stress-related genes in the compatible citrus-Citrus leprosis virus interaction
Leprosis, caused by Citrus leprosis virus, cytoplasmic type (CiLV-C), is the main viral disease in the Brazilian citrus industry. This occurs because of the widespread source of inoculum and the year-round presence of the vector, the tenuipalpid mite Brevipalpus phoenicis, in citrus plants. In addition, while some Citrus species are resistant to CiLV-C, C. s

7. Aspectos moleculares da imunidade de Lutzomyia longipalpis (Díptera:Psychodidae). / Molecular aspects of immunity of Lutzomyia longipalpis (Díptera: Psychodidae).
Sandflies are known for the transmission of leishmaniasis but can also transmit viral and bacterial diseases. Also, sandflies get in contact with several insect pathogens like fungi and helminths. The strategies used by sandflies for defense against pathogens are mostly unknown. The main infection path is through blood feeding and the midgut is the first imm

8. The 42-kDa coat protein of Andean potato mottle virus acts as a transcriptional activator in yeast
Interactions of viral proteins play an important role in the virus life cycle, especially in capsid assembly. Andean potato mottle comovirus (APMoV) is a plant RNA virus with a virion formed by two coat proteins (CP42 and CP22). Both APMoV coat protein open reading frames were cloned into pGBT9 and pGAD10, two-hybrid system vectors. HF7c yeast cells transfor

9. Molecular and biological characterization of a begomovirus isolated from tomato, Lycopersicon esculentum Mill. in the state of Goiás and its interaction with the vector Bemisia argentifolii Bellows &Perring / Caracterização molecular e biológica de um begomovírus isolado de tomateiro, Lycopersicon esculentum Mill., no estado de Goiás e sua interação com o vetor Bemisia argentifolii Bellows &Perring
The whitefly-transmitted viruses from the family Geminiviridae, genus Begomovirus, have been reported as an economically important pathogen group that affect important crops in tropical and subtropical countries. Since the beginning of the 1980 decade, the occurrence of the whitefly associated to Begomovirus infection has drastically increased worldwide. In

10. Modulations of the in vitro translational efficiencies of Yellow Fever virus mRNAs: interactions between coding and noncoding regions.
As an approach to define the structural features within the 5' noncoding region of Yellow Fever virus (YFV) that modulate mRNA translational efficiency, we have studied how minor changes in this region affect the translational capacity in vitro of the corresponding mRNAs. A cDNA sequence coding for part of the YFV structural proteins was inserted into the ve

11. Characterization of a cis-Acting Sequence in the pol Region Required To Transfer Human Foamy Virus Vectors
To identify cis-acting elements in the foamy virus (FV) RNA pregenome, we developed a transient-vector-production system based on cotransfection of indicator gene-bearing vector and gag-pol and env expression plasmids. Two elements which were critical for vector transfer were found and mapped approximately. The first element was located in the RU5 leader and

12. In vivo model of adeno-associated virus vector persistence and rescue.
Gene therapy vectors based on human DNA viruses could be mobilized or rescued from individuals who are subsequently infected with the corresponding wild-type (wt) helper viruses. This phenomenon has been effectively modeled in vitro with both adenovirus (Ad) and adeno-associated virus (AAV) vectors but has not previously been studied in vivo. In the current
