Our study implicates both chromosomal and plasmid-encoded toxins as contributors to intestinal secretion caused by S. J Clin Invest 95 : — The overarching goal of this study was to validate mouse tissue as a useful model of intestinal secretion caused by exposure to secreted toxins. Acknowledgments The authors would like to thank Dr. Arun K. James P. Vaccine activation of the nutrient sensor GCN2 in dendritic cells enhances antigen presentation.

    Gut 40 : — Infections are caused by microbial pathogens from different domains of the tree of life—viruses, bacteria, or eukaryotes. Given the benefits of utilizing mouse tissue, we proceeded with mouse jejunum for the remainder of the experiments with T supernatants serving as the positive control.

    While this approach was important to demonstrate that toxin addition alone was sufficient to induce changes in Isc, the higher level of protein expressed and possible alterations from production in E.

    Interestingly, augmenting autophagy with rapamycin was found to enhance presentation of a BCG antigen by antigen-presenting cells and enhance protection against M. Although the invasion process has been thoroughly dissected, the mechanisms by which Shigella induces secretory diarrhea are less defined.

    In addition to their roles in infection, these same pathways may be involved in targeting damaged organelles in uninfected cells Huang and Brumell, ; Sorbara and Girardin, and in removing protein aggregates, for example, those associated with neurodegenerative diseases Rubinsztein et al.

    Deciphering the roles of cytoskeletal elements in autophagy regulation and the innate immune response should be an active area of future investigation. Finally, our understanding of signal transduction pathways and their contribution to diseases like cancer has also been heavily influenced by the study of viruses Martin, A second example highlights how the study of pathogens can reveal new pathways that influence autophagy, such as an emerging link between cytoskeletal elements and the autophagy machinery Mostowy,

    All efforts were made to minimize suffering during euthanasia of the mice.

    This study was carried out in strict accordance with the recommendations in the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health. In order to identify the toxins encoded on the chromosome, we first analyzed a deletion mutant of the previously implicated set1 A and set1 B genes, which encode ShET1 strain When a Partner Is Excluded.
