Die zellulären Immunantworten auf rekombinante und native Antigene von Schistosoma mansoni wurden in einer definierten Studienpopulation von 64 Personen in Ägypten untersucht, wobei Daten aus einer zweijährigen Beobachtung der Exposition, Infektion und Reinfektionsmuster verwendet wurden, um mutmaßlich resistente (R) und empfängliche (S) Personen kategorisch zu klassifizieren. Anhand von peripheren mononukleären Blutzellen (PBMCs) der an der Studie teilnehmenden Personen wurden die Lymphozytenproliferation und die Zytokinproduktion (IL-5, IL-10 und IFN-γ) in vitro als Reaktion auf definierte rekombinante und native Paramyosin-Antigene („R-Para' bzw. „N-Para') und native lösliche Präparate aus adulten Würmern (SAWA) gemessen. Darüber hinaus deuten die zellulären Reaktionen auf die Antigene „R-Para' und „SAWA' darauf hin, dass die Th1-Reaktion für die Vorhersage der Resistenz in dieser Population wichtig zu sein scheint. Von den getesteten rekombinanten Ag induzierte R-Para signifikante Mengen an IFN-γ. Die Produktion von IL-10, einem Zytokin vom Th2-Typ, war stark an der Immunregulation beteiligt. Von Bedeutung war der Nachweis einer durch „SAWA und R-Para' induzierten IFN-γ-Reaktion für die Vorhersage der Resistenz.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...
  • Advances in Flavivirus Research
    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

  • Brain Asymmetry of Structure and/or Function
    Lesley J. Rogers / Lesley JRogers
    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...

There has been progress in the treatment of acute m...
