T1/ST2 - an IL-1 receptor-like modulator of immune responses

Th2-associated factors such as IL-4 are involved in both the development of Th2 responses (via modulating Th2 cell differentiation) and in the effector phase of Th2 responses (via modulating macrophage activation). The IL-1 receptor-like protein ST2 (T1, Fit-1, or DER4) is expressed as a membrane-bound (ST2L) or secreted form (sST2), and has been clearly implicated as a regulator of both the development and effector phases of Th2-type responses. Here we analyze the mechanisms and therapeutic implications of the unique ability of ST2 to promote development and function of type 2 helper T cells through a positive feedback loop, as well as to act as a negative feedback modulator of macrophage pro-inflammatory function.

Identification of membrane-bound and secreted proteins from Echinococcus granulosus by signal sequence trap

The signal sequence trap technique was applied to identify genes coding for secreted and membrane bound proteins from Echinococcus granulosus, the etiologic agent of cystic hydatid disease. An E. granulosus protoscolex cDNA library was constructed in the AP-PST vector such that randomly primed cDNAs were fused with a placental alkaline phosphatase reporter gene lacking its endogenous signal peptide. E. granulosus cDNAs encoding a functional signal peptide were selected by their ability to rescue secretion of alkaline phosphatase by COS-7 cells that had been transfected with the cDNA library. Eighteen positive clones were identified and sequenced. Their deduced amino acid sequences showed significant similarity with amino acid transporters, Krebs cycle intermediates transporters, presenilins and vacuolar protein sorter proteins. Other cDNAs encoded secreted proteins without homologues. Three sequences were transcribed antisense to E. granulosus expressed sequence tags. All the mRNAs were expressed in protoscoleces and adult worms, but some of them were not found in oncospheres. The putative E. granulosus secreted and membrane bound proteins identified are likely to play important roles in the metabolism, development and survival in the host and represent potential targets for diagnosis, drugs and vaccines against E. granulosus.

Európai lepkeszúnyog fajok potenciális elterjedése a 21. században

Leishmaniasis is a typical vectorial disease transmitted by Psycodidae vectors (Lutzomyans, Phlebotomus species). The worldwide observed 1,5-2 million new cases and 60,000 death caused by Leishmania parasites per year make leishmaniasis is one of the most important vectorial disease in the tropicals and warm temperate areas of the World. In the human environment dogs and cats are the most important hosts of the different leishmania agents. The different leishmania species cause symptomatically cutan or visceral disease forms, but many other type of the disease has recognised. Phlebotomus species are sensitive to climatic patterns, they require hight relative air humidity, mild winters and long and warm vegetation period, but the environmental requirements of the species naturally is not the same. Due to climate change in the near future the climate of Western and Central Europe could allow the colonisation of these highly populated areas with also the vectors and the parasites. Our aim was to analyse the environmental patterns of the current distribution area of 8 important sand flies (P. ariasi, P. perniciosus, P. perfiliewi, P. papatasi, P. tobbi, P. neglectus, P. similis and P. sergenti) using the 1960-1990 period’s climate as reference. Using climate envelope modeling we determined these climatic characters and using the REMO climate projection we created the recent and the near-future (2011-2040 and 2041-2070) potential distribution area of the sand flies. The current known area of many Phlebotomus species restricted either to the western or to the eastern Mediterranean Basin. We found that their climatic requirements are could not explain their segregation, it is maybe the consequence of their evolutionary history (geographical barriers and paleoclimatic history). By the end of the 2060’s most parts of Western Europe can be colonized by sand flies, mostly by P. ariasi and P. pernicosus. P. ariasi showed the greatest potential northward expansion. Our model resulted 1 to 2 months prolongation of the potentially active period of P. neglectus P. papatasi and P. perniciosus for the 2070’s in Southern Hungary. As the climate becomes drier and warmer, sand flies will occupy more and more parts of Hungary. Our findings confirm the concerns that leishmanisais can become a real hazard for the major part of the European population to the end of the 21th century and the Carpathian Basin is a particularly vulnerable area.

Leishmaniasis Mimicking Lymphoma and/or Liver Cirrhosis

A 76-year-old man was admitted to hospital with fever, weight loss, pancytopenia, hepatosplenomegaly and a double monoclonal component IgM-IgG-k, suggesting a diagnosis of myeloma. Bone marrow and liver biopsies disclosed the presence of Donovan bodies, and the titre of anti-Leishmania antibodies was extremely high. After treatment with liposomal amphotericin B, the titre of antibodies fell considerably, while monoclonal components, pancytopenia and clinical symptoms slowly disappeared. Polyclonal γ-globulins are made of innumerable monoclonal components, one of which can appear as a recognizable band and be misdiagnosed as myeloma when representing the high titre of an antibody directed towards a specific antigen.

Resposta imune à saliva de flebotomíneos (diptera: psychodidae) em indivíduos residentes em áreas urbana e periurbana no nordeste do brasil

Visceral leishmaniasis (VL) has a wide geographical distribution in tropical and subtropical areas of the planet, which is a protozoan parasite of the genus Leishmania. This pathogen is transmitted to the host through the sandflies bite, with its saliva, the immune response that leads to both. In the state of Rio Grande do Norte, 85% of the sand flies captured is Lutzomyia longipalpis, but the second most abundant, Lutzomyia evandroi, it deserves emphasis because its wide distribution and eclectic behavior. The exposure of people living in endemic areas for the insect vector VL greatly increases the chances of infection. This study aimed to evaluate aspects of the epidemiological profile of VL in endemic areas of human and nonendemic in the metropolitan area of Natal, as well as verify the abundance and seasonal fluctuations of sandflies species in two counties endemic for VL. Were collected in the municipalities of Nísia Floresta, Parnamirim, São Gonçalo do Amarante and Macaíba, of which groups of females were separated for further dissection of the salivary glands and identification of species. The blood samples used were from individuals of two Natal s districts where it has never been reported cases of VL and neighborhoods of Parnamirim applicants who present cases of VL. In the municipality of Nísia Floresta, the most abundant species was L. evandroi with 38.39%, followed by L. longipalpis with 36.22%, L. walkeri 19.67% L. lenti 3.81%, L. wellcomei 1.39% and L. whitmani 0.52%. Already in Parnamirim the proportions were L. walkeri with 73.15%, L. evandroi with 10.55%, L. wellcomei 7.63%, L. longipalpis 6.37%, L. whitmani 1.46%, L. sordellii 0.52%, L. intermedia 0.21 and L. shanonni 0.1%. In both municipalities was observed higher abundance of species distributed in the initial months of the year, as February and March. The study showed that no difference in exposure to the vector of VL among individuals from endemic and non endemic area for this disease. But there are differences in exposure between individuals of L. longipalpis and L. evandroi, confirming the great powers of the first vector. It was also characterized as predominant phenotype in the population of endemic areas who had negative serologic responses to antigens of Leishmania and result in negative Montenegro skin test (DTH), indicating that much of the population hasn t been bitten by infected insects

Exploring the environmental diversity of kinetoplastid flagellates in the high-throughput DNA sequencing era

The class Kinetoplastea encompasses both free-living and parasitic species from a wide range of hosts. Several representatives of this group are responsible for severe human diseases and for economic losses in agriculture and livestock. While this group encompasses over 30 genera, most of the available information has been derived from the vertebrate pathogenic genera Leishmania and Trypanosoma. Recent studies of the previously neglected groups of Kinetoplastea indicated that the actual diversity is much higher than previously thought. This article discusses the known segment of kinetoplastid diversity and how gene-directed Sanger sequencing and next-generation sequencing methods can help to deepen our knowledge of these interesting protists.
