Fishing For The Right Probiotic: Investigating The Mechanism Of Mucosal-Bacterial Interactions At The Interface Of Health And Productivity In Salmonid Aquaculture, Luana Langlois
Electronic Thesis and Dissertation Repository
Aquaculture is vital for the global food supply, but the high incidence of infectious diseases threatens the industry’s productivity. The intestinal mucosa is a key port of entry for pathogens and provides an extensive interface for host-microbe interactions. Tight junctions are at the core of gut barrier function and the mucosal health of finfish. Disruption of these complexes gives rise to sepsis, which leads to systemic inflammation and death. The present study employs a combinatorial approach that integrates in vitro and in vivo analyses to gain actionable insights into the mechanism of microbial-mediated modulation of host health. The experiments outlined …
Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, Shahab Meshkibaf
Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, Shahab Meshkibaf
Electronic Thesis and Dissertation Repository
The pleiotropic cytokine granulocyte-colony stimulatory factor (G-CSF) is mainly required for the generation of neutrophils, but its role in macrophage generation has also been reported. In addition, G-CSF is effective for the down-regulation of inflammatory cytokines and ameliorating gut disorders, such as colitis. However, the G-CSF function in macrophage generation and gut immunity remains unclear. The first focus of this thesis was to assess the role of G-CSF in macrophage generation and its contribution to gut immunity. G-CSF was found to promote the generation of Gr-1high/F4/80+ macrophages in macrophage (M)-CSF-treated bone marrow cells, most likely through suppressing cell death. Gr-1high …
Probiotic Therapy For Heart Failure: Investigating The Potential Anti-Hypertrophic Properties Of Probiotics, Grace L. Ettinger
Probiotic Therapy For Heart Failure: Investigating The Potential Anti-Hypertrophic Properties Of Probiotics, Grace L. Ettinger
Electronic Thesis and Dissertation Repository
Heart failure patients face a five-year 50% mortality rate, due to impaired cardiac function and hypertrophy of the heart. Probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. Considering the established cardiovascular benefits of some probiotics, including reduction of cholesterol and hypertension, it was hypothesized that probiotics can improve outcomes of heart failure. Probiotics or controls were administered orally to an animal model for heart failure. Those receiving probiotics showed a significant improvement in cardiac hypertrophy and an attenuation of heart failure compared to control. No changes in gut microbial composition occurred. …
