Expression of IL-10 receptors on epithelial cells from the murine small and large intestine (2000)

Denning, Timothy L., Campbell, Nicola A., Song, Fei, Garofalo, Roberto P., Klimpel, Gary R., Reyes, Victor E., ...

The appearance of chronic intestinal inflammation in IL-10 knockout mice suggests IL-10 may inhibit adverse responses to luminal antigen. Moreover, this inflammation is associated with an increase in...

Immunotoxicology of Regional Lymphoid Tissue: The Respiratory and Gastrointestinal Tracts and Skin (1995)

KAWABATA, THOMAS T., BURLESON, GARY R., ERNST, PETER B., ULLRICH, STEPHEN E.

The area of immunotoxicology has grown significantly over the past decade. Most of the research on methods development and validation and mechanisms of action have focused on the systemic immune...

Phenotypic and functional assessment of intraepithelial lymphocytes bearing a 'forbidden' {alpha}{beta} TCR (1994)

Croitori, Kenneth, Blenenstock, John, Ernst, Peter B.

Differences in the surface antigen phenotype, such as the expression CD8 as an αα homodimer or the lack of Thy-1, on Intestinal Intraepithelial lymphocytes (IEL) are related, In part, to...

Transforming growth factor-{beta}1 enhances IgG and IgA sheep red blood cell responses (1992)

Zettel, Lenore, Clark, David A., Ernst, Peter B.

Antibody responses to ingested antigens can be inhibited by a mechanism known as oral tolerance which acts to prevent excessive stimulation from luminal contents. Local IgA responses can be induced...

Helicobacter pylori Modulates Lymphoepithelial Cell Interactions Leading to Epithelial Cell Damage through Fas/Fas Ligand Interactions

Wang, Jide, Fan, Xuejun, Lindholm, Catharina, Bennett, Michael, O'Connoll, Joe, Shanahan, Fergus, ...

Helicobacter pylori causes a common chronic infection of humans that leads to epithelial cell damage. Studies have shown that apoptosis of the gastric epithelium is increased during infection and...

Helicobacter pylori Does Not Require Lewis X or Lewis Y Expression To Colonize C3H/HeJ mice

Takata, Tohru, El-Omar, Emad, Camorlinga, Margarita, Thompson, Stuart A., Minohara, Yutaka, Ernst, Peter B., ...

Helicobacter pylori strains frequently express Lewis X (Lex) and/or Ley on their cell surfaces as constituents of the O antigens of their lipopolysaccharide molecules. To assess the effect of Lex and...

IκB Kinase Is a Critical Regulator of Chemokine Expression and Lung Inflammation in Respiratory Syncytial Virus Infection

Haeberle, Helene A., Casola, Antonella, Gatalica, Zoran, Petronella, Sharon, Dieterich, Hans-Juergen, Ernst, Peter B., ...

Respiratory syncytial virus (RSV) is the major etiologic agent of severe epidemic lower respiratory tract infections in infancy. Airway mucosal inflammation plays a critical role in the pathogenesis...

Reactive Oxygen and Nitrogen Species Differentially Regulate Toll-Like Receptor 4-Mediated Activation of NF-κB and Interleukin-8 Expression

Ryan, Kieran A., Smith, Michael F., Sanders, Michael K., Ernst, Peter B.

Toll-like receptor 4 (TLR4) has been identified as a transmembrane protein involved in the host innate immune response to gram-negative bacterial lipopolysaccharide (LPS). Upon activation by LPS...

Expanded B cell population blocks regulatory T cells and exacerbates ileitis in a murine model of Crohn disease

Olson, Timothy S., Bamias, Giorgos, Naganuma, Makoto, Rivera-Nieves, Jesús, Burcin, Tracy L., Ross, William, ...

SAMP1/YitFc mice develop discontinuous, transmural inflammatory lesions in the terminal ileum, similar to what is found in human Crohn disease. Compared with the mesenteric lymph nodes (MLNs) of AKR...

B-Cell and T-Cell Immune Responses to Experimental Helicobacter pylori Infection in Humans

Nurgalieva, Zhannat Z., Conner, Margaret E., Opekun, Antone R., Zheng, Carl Q., Elliott, Susan N., Ernst, Peter B., ...

The acute antibody and T-cell immune response to Helicobacter pylori infection in humans has not been studied systematically. Serum from H. pylori-naive volunteers challenged with H. pylori and cured...

Antisense RNA Modulation of Alkyl Hydroperoxide Reductase Levels in Helicobacter pylori Correlates with Organic Peroxide Toxicity but Not Infectivity▿

Croxen, Matthew A., Ernst, Peter B., Hoffman, Paul S.

Much of the gene content of the human gastric pathogen Helicobacter pylori (∼1.7-Mb genome) is considered essential. This view is based on the completeness of metabolic pathways, infrequency of...
