Intercellular Spreading Of Porphyromonas Gingivalis Infection In Primary Gingival Epithelial Cells, Özlem Yilmaz, Philippe Verbeke, Richard J. Lamont, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

Porphyromonas gingivalis, an important periodontal pathogen, is an effective colonizer of oral tissues. The organism successfully invades, multiplies in, and survives for extended periods in primary gingival epithelial cells (GECs). It is unknown whether P. gingivalis resides in the cytoplasm of infected cells throughout the infection or can spread to adjacent cells over time. We developed a technique based on flow cytofluorometry and fluorescence microscopy to study propagation of the organism at different stages of infection of GECs. Results showed that P. gingivalis spreads cell to cell and that the amount of spreading increases gradually over time. There was a …

Here we report the results of an investigation into the possibility that one mechanism responsible for the establishment of persistent human immunodeficiency virus infection is an early regulatory T (Treg) cell response that blunts virus- specific responses. Using the simian immunodeficiency virus (SIV)–infected rhesus macaque model, we show that, indeed, viral replication and immune activation in lymphatic tissue drive a premature immunosuppressive response, with dramatic increases in the frequencies of CD4+CD25+FOXP3+ Treg cells, transforming growth factor–β1+ cells, interleukin–10+ cells, and indoleamine 2,3-dioxygenase+CD3+ cells.When we compared SIV infection with rhesus cytomegalovirus (RhCMV) …

Sl1 Rna Gene Recovery From Enterobius Vermicularis Ancient Dna In Pre-Columbian Human Coprolites, Alena M. Iñiguez, Karl Reinhard, Marcelo Luiz Carvalho Gonçalves, Luiz Fernando Ferreira, Adauto Araújo, Ana Carolina Paulo Vincente

Karl Reinhard Publications

Enterobius vermicularis, pinworm, is one of the most common helminths worldwide, infecting nearly a billion people at all socio-economic levels. In prehistoric populations the paleoparasitological findings show a pinworm homogeneous distribution among hunter-gatherers in North America, intensified with the advent of agriculture. This same increase also occurred in the transition from nomad hunter-gatherers to sedentary farmers in South America, although E. vermicularis infection encompasses only the ancient Andean peoples, with no record among the pre-Colombian populations in the South American lowlands. However, the outline of pinworm paleo epidemiology has been supported by microscopic finding of eggs recovered from coprolites. …

Tannerella Forsythia, A Periodontal Pathogen Entering The Genomic Era, Anne C. R. Tanner, Jacques Izard Jan 2006

Tannerella Forsythia, A Periodontal Pathogen Entering The Genomic Era, Anne C. R. Tanner, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Several questions need to be addressed to evaluate whether Tannerella forsythia is to be considered a periodontal pathogen. T. forsythia has been detected in periodontal health and disease, so could it be a pathogen? The species was not detected in many studies despite finding other putative pathogens, so could it be important in pathogenicity? The challenges of working with T. forsythia include its fastidious and anaerobic growth requirements for cultural detection. Thus, studies associating T. forsythia with periodontal and other oral infections have used noncultural approaches (immunoassays and DNA-based assays) in addition to cultural approaches. We feel …

The Use Of Genomewide Enu Mutagenesis Screens To Unravel Complex Mammalian Traits: Identifying Genes That Regulate Organ-Specific And Systemic Autoimmunity, Gerard F. Hoyne, Christopher C. Goodnow

Health Sciences Papers and Journal Articles

T-cell development is perhaps one of the best understood processes of mammalian cell differentiation, as many of the genes and pathways have been identified. By contrast, relatively little is known about the genes and pathways involved in immunological tolerance to self-antigens. Here, we describe the challenges associated with a genomewide screen designed at identifying new immune regulatory genes that uses a model of organ-specific autoimmunity leading to type 1 diabetes. The successful propagation and identification of the new gene variants will shed light on the various developmental checkpoints in lymphocyte development that are crucial for establishing tolerance to self-antigens.

Effects Of Dietary Fluoride Levels On Growth, Serum Indexes And Antioxidant Systems In Growing Pigs, Xin Tao, Zi Rong Xu, Yi Zhen Wang Jan 2006

Effects Of Dietary Fluoride Levels On Growth, Serum Indexes And Antioxidant Systems In Growing Pigs, Xin Tao, Zi Rong Xu, Yi Zhen Wang

Turkish Journal of Veterinary & Animal Sciences

Ninety-six growing pigs were used to evaluate the effects of fluoride levels on growth performance, serum indexes and antioxidant systems. Four dietary treatments were formulated by supplementing fluorine (as NaF) to provide the following added fluorine levels: 0, 50, 100 and 150 mg/kg. The results showed that pigs consuming diets with 100 and 150 mg/kg fluorine added had poor growth performance, and most serum biochemical indexes were significantly altered compared to the control (P < 0.05). On the other hand, serum and liver MDA concentration significantly increased due to the addition of 150 mg/kg fluorine (P < 0.05). T-AOC levels and the activities of SOD, GSH-PX, CAT and GST of serum and liver in fluoride added groups decreased, most of which altered significantly (P < 0.05). These results indicated that excessive fluoride ingestion had an adverse effect on animal health and performance.
