Analysis of goldfish innate immunity following exposure to oil sands process affected water
DownloadFall 2013
The acute and sub chronic effects of oil sands process affected water (OSPW) and its toxic component, naphthenic acids (NAs) were examined. I exposed goldfish for one (acute), or 12 (sub chronic) weeks and examined immune gene expression, macrophage function, the ability of exposed fish to...

Analysis of the acute phase response in goldfish (Carassius auratus L.) infected with Trypanosoma carassii
DownloadSpring 2016
The innate immune response is a fundamental defense mechanism in bony fishes and a crucial component of innate immunity is the acute phase response (APR). The APR is a systemic and/or local response to any injury, infection, or trauma and is characterized by a change in the blood composition of...

Teleosts rely on innate immunity to protect themselves from pathogens. Colony stimulating factor-1 (CSF-1) and its cognate receptor CSF-1R control survival, proliferation, differentiation and function of macrophages. Recently, a novel soluble form of CSF-1R (sCSF-1R) was identified in goldfish....

Fungal pathogens are recognized by Dectin-1, a pattern recognition receptor expressed on mammalian innate immune cells. Dectin-1 detects β-glucans, which are polymers of glucose that are a main component of the fungal cell wall. While purified, soluble β-glucans have been used in the clinic as...

Inflammatory Bowel Diseases (IBD) are a group of conditions characterized by chronic inflammation and a dysregulated immune response of the gastrointestinal tract. The etiology is unknown; however, research has indicated a complex relationship between environmental stimuli, genetic...

Development of imaging-based techniques to examine signalling properties of channel catfish (Ictalurus punctatus) leukocyte immune-type receptors (IpLITRs)
DownloadSpring 2017
Cells of the innate immune system have the ability to rapidly detect and eliminate pathogens using surface-expressed immunoregulatory receptors that translate extracellular binding into effector functions such as degranulation, cytokine secretion, cell-mediated cytotoxicity, and phagocytosis....

Effects of macrophages and noggin suppression on the BMP-2-induced osteogenesis of human bone marrow mesenchymal stem cells
DownloadSpring 2011
The osteogenic effects of bone morphogenetic protein-2 (BMP-2) on human mesenchymal stem cells (MSCs) are less profound than expected as compared with rodent cells, and supraphysiological dose of BMP-2 is required to achieve desired clinical outcome. The mechanism for this phenomenon is unclear....

Examination of channel catfish (Ictalurus punctatus) leukocyte immune-type receptor-mediated crosstalk regulation of phagocytosis
DownloadFall 2020
Across vertebrates, innate immune cells are capable of initiating a range of potent effector responses that are designed to destroy or contain foreign microbial invaders. The execution and regulation of various innate cellular responses is mediated by a dedicated repertoire of cell...

In response to pathogens, immune cells induce protective effector functions, such as degranulation, phagocytosis and cytokine secretion, which are initiated by stimulatory or inhibitory immunoregulatory receptors expressed on leukocytes. Using a fish immunological model system, the focus of my...
