Molecular imaging of cyclooxygenase-2 (COX-2) and autotaxin (ATX) in cancer using positron emission tomography (PET)
DownloadFall 2020
Positron emission tomography (PET) relies on the use of β+-emitting radionuclide-bearing molecules congregating and decaying at a specific site of interest. Use of these molecules, called radiotracers, which target common tumor characteristics has become a pillar in the diagnosis of cancer and...

Macrophages are the primary cells of innate immunity that provide the first line of defence against any external stimuli. Their phagocytic properties enable them to engulf invading microbes or foreign particles. The phagocytic capability of macrophages plays a major role in interfering with drug...

Neutrophil elastase alters the murine gut mirobiota resulting in enhanced Salmonella colonization
Download2012
Hartmann, Martin, Sekirov, Inna, Finlay, B. Brett, Al-Zahrani, Fatimah, Willing, Benjamin P., Ferreira, Rosana B. R., Gill, Navkiran, Antunes, L. Caetano M.
The intestinal microbiota has been found to play a central role in the colonization of Salmonella enterica serovar Typhimurium in the gastrointestinal tract. In this study, we present a novel process through which Salmonella benefit from inflammatory induced changes in the microbiota in order to...

In this review article we present an overall summary of the role that high-grain/low forage diets have on rumen composition of microbiota and how changes in the diet affect the release of bacterial cell wall components that are toxic to the host. One of these toxic compounds is lipopolysaccharide...

The overarching idea of this thesis stemmed from previous work in our lab, where it was noticed that females and males exhibited different disease trajectories in a model of Multiple Sclerosis. Combined with our observation of different outcome metrics for peripheral nociception suggested that...

Pathologic Evaluation of Type 2 PorcineReproductive and Respiratory SyndromeVirus Infection at the Maternal-FetalInterface of Late Gestation Pregnant Gilts
Download2016-03-10
Novakovic, Predrag, Harding, John C. S., Al-Dissi, Ahmad, Ladinig, Andrea, Detmer, Susan E.
The pathogenesis of fetal death caused by porcine reproductive and respiratory syndromevirus (PRRSV) remains unclear. The objective of this study was to improve our understand-ing of the pathogenesis by assessing potential relationships between specific histopatho-logical lesions and PRRSV RNA...

Regulation of autotaxin expression and secretion by lysophosphatidate and sphingosine 1-phosphate
Download2015
Zhao, Yuan Y., McMullen,Todd P. W. , Brindley, David N., Curtis, Jonathan M., Benesch, Matthew G. K.
Autotaxin (ATX) is a secreted enzyme, which produces extracellular lysophosphatidate (LPA) from lysophosphatidylcholine (LPC). LPA activates six G protein-coupled receptors and this is essential for vasculogenesis during embryonic development. ATX is also involved in wound healing and...

Revisiting the antifibrinolytic effect of carboxypeptidase N: novel structure and regulation
DownloadFall 2010
Carboxypeptidase N (CPN) is a plasma carboxypeptidase that was discovered in the 1960s as a regulator of inflammation and vascular tone. Through the removal of carboxy-terminal basic residues, CPN alters the activity or binding specificity of inflammatory mediators and vasoactive peptides. CPN...

Role of Cytochrome P450 1B1 in Inflammation-induced Cardiac Hypertrophy
2023-05-17
ElKhatib, Mohammed, El-Kadi, Ayman
A great deal of research has demonstrated the involvement of cytochrome P450 (CYPs) enzymes and its metabolism of arachidonic acid (AA) in the modulation of cardiac hypertrophy (CH) pathogenesis. Multiple studies demonstrated that inflammation is a major contributor to CH and is known to...

12,13-dihydroxy-9z-octadecenoic acid (12,13-DiHOME) is a linoleic acid-derived cardiac metabolite produced in endotoxin-induced cardiomyopathy, correlating with myocardial dysfunction, inflammation, and mitochondrial damage. The contribution of 12,13-DiHOME to inflammation in the heart is...
