Cellular Adaptation Of Macrophages To Anthrax Lethal Toxin-Induced Pyroptosis Via Epigenetic Mechanisms, Chae Young Han
University of Western Ontario - Electronic Thesis and Dissertation Repository
Cellular adaptation to microbial stresses has been demonstrated in several cell types. Macrophages (MФ) are sentinel immune cells fending off invading microbes. Anthrax lethal toxin (LeTx) is a key virulence factor released by Bacillus anthracis that causes rapid cell death, pyroptosis. A small number of RAW246.7 macrophages (~4%) exposed to a non-lethal dose of LeTx become resistant to LeTx-induced pyroptosis for ~ 4 weeks, termed “toxin-induced resistance (TIR)”. Here, I showed that high levels of DNA methyl transferase1 (DNMT1) expression were maintained although global genomic methylation levels were not high in TIR. TIR cells treated with the DNMT inhibitor 5-azacitidine ...

Influenza is a highly contagious respiratory disease. Yearly epidemics and pandemics account for high morbidity and mortality worldwide. Lung immunopathology is a major factor causing death following influenza. In addition, secondary bacterial superinfections that occur after influenza further complicate the lung immunopathology and contribute to higher morbidity and mortality. The research presented in this thesis addressed important, understudied questions in the complicated field of tissue immunopathogenesis and host defense to influenza and pneumococcal infections. Firstly, in a model of acute respiratory influenza infection, we found that the classically proinflammatory cytokine TNF plays a dual and biphasic role at different times ...

Burkholderia cepacia complex (Bcc) is an opportunistic pathogen in cystic fibrosis patients which is inherently resistant to antimicrobial agents. The mechanisms of attachment and pathogenesis of Bcc, a group of 17 species, are poorly understood. The most commonly identified Bcc species in newly colonised patients, Burkholderia multivorans, continues to be acquired from the environment. Development of therapies which can prevent or reduce the risk of colonization on exposure to Bcc in the environment would be a better alternative to antimicrobial agents. Previously, it has been shown that Bcc strains bound to many glycolipid receptors on lung epithelia. Using a real-time ...
