Azithromycin Therapy Reduces Cardiac Inflammation And Mitigates Adverse Cardiac Remodeling After Myocardial Infarction, Ahmed Hamish Neamah Al-Darraji
Azithromycin Therapy Reduces Cardiac Inflammation And Mitigates Adverse Cardiac Remodeling After Myocardial Infarction, Ahmed Hamish Neamah Al-Darraji
Theses and Dissertations--Pharmacology and Nutritional Sciences
Introduction: Myocardial infarction (MI) remains the leading cause of morbidity and mortality worldwide. Induced by cardiomyocyte death, MI initiates a prolonged and uncontrolled inflammatory response which impairs the healing process. Immune cells, such as macrophages, play a central role in organizing the early post-MI inflammatory response and the subsequent repair phase. Two activation states of macrophages have been identified with distinct and complementary functions (inflammatory vs. reparatory). This bimodal pattern of macrophage activation is an attractive therapeutic target to favorably resolve post-MI inflammation and enhance recovery. It has been demonstrated that azithromycin (AZM), a commonly used antibiotic with immunomodulatory effects, …
Pyocyanin, A Virulence Factor Produced By Sepsis-Causing Pseudomonas Aeruginosa, Promotes Adipose Wasting And Cachexia, Nika Larian
Theses and Dissertations--Pharmacology and Nutritional Sciences
Sepsis is a leading cause of death among critically ill patients that results in metabolic alterations including hypercatabolism, lipoatrophy, and muscle wasting, contributing to the development of cachexia. Septic cachexia is associated with loss of body weight, fat mass, and lean mass and dysregulated immune function. There are currently no efficacious treatment strategies for septic cachexia, and nutritional interventions have limited success in preventing hypercatabolic wasting. Pyocyanin is a virulence factor produced by sepsis-causing Pseudomonas aeruginosa that has been shown to activate the aryl hydrocarbon receptor (AhR), increase inflammation, and produce reactive oxygen species. Thus, pyocyanin represents a novel mechanistic …
