Modeling fimbriae mediated parasite–host interactions

Journal of Theoretical Biology, 2010
Type 1 fimbriae are a known virulence factor in a number of pathogenic enterobacteriaceae, including Salmonella, Shigella and E. coli. Yet, they are also expressed by some commensal strains, notably of E. coli. One hypothesis of the role of fimbriae in commensals is that they evoke a small but tolerable host immune response in order to have the host ...

Helical structure of Bordetella pertussis fimbriae [PDF]

Journal of Bacteriology, 1986
The helical structures of Bordetella pertussis fimbriae of serotypes 2 and 6 were determined by optical diffraction analysis of electron micrographs of negatively stained paracrystalline bundles of purified fimbriae. The fimbrial structure is based on an axial repeat of 13 nm that contains five repeating units in two complete turns of a single-start ...

Plant‐produced encapsulin displays non‐typhoidal Salmonella enterica antigens and assembles into mosaic nanoparticles

The FEBS Journal, EarlyView.
This study investigates the potential of encapsulin as an antigen display platform for the development of a candidate Salmonella vaccine for poultry. Encapsulin constructs were transiently expressed in Nicotiana benthamiana where they accumulated to high levels.

Characterization of an Inherited Neurologic Syndrome in Toyger Cats with Forebrain Commissural Malformations, Ventriculomegaly and Interhemispheric Cysts. [PDF]

, 2016
BackgroundIn children, frequent congenital malformations with concomitant agenesis of the corpus callosum are diagnosed by neuroimaging in association with other cerebral malformations, including interhemispheric cysts and ventriculomegaly.

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

The dysregulation of innate immunity by Porphyromonas gingivalis in the etiology of Alzheimer's disease

Journal of Internal Medicine, EarlyView.
Abstract The etiology of Alzheimer's disease (AD) remains under active debate. In this perspective, we explore the hypothesis that a primarily infection‐caused chronic dysregulation and weakening of human innate immunity via the underexpression, degradation, and inactivation of innate immune proteins necessary for direct antimicrobial effects and ...
