Proteolytic Manipulation Of Neutrophil Responses And The Efferocytic Synapse By Porphyromonas Gingivalis., Kelley N. Cooper

Electronic Theses and Dissertations

Porphyromonas gingivalis (Pg) is etiologically associated with chronic periodontitis, a highly prevalent chronic inflammatory disease characterized by the destruction of hard and soft tissues of the periodontium. Pg is adapted to live in the human oral subgingival niche, a hostile environment dominated by excessive numbers of activated neutrophils and antimicrobial mediators. Its survival is contingent upon prompt and effective inactivation of neutrophil effector functions. In this dissertation, I uncover a novel pathogenic mechanism employed by Pg that disarms the antimicrobial capacity of live neutrophils and simultaneously sequesters them within macrophages. Mechanistically, RgpB, a cysteine protease produced by Pg …

Differential Responses Of Human Neutrophils To Legionella Species., Hannah E. Hanford

Electronic Theses and Dissertations

Legionella species are Gram-negative facultative intracellular bacterial pathogens commonly found in freshwater or soil environments where they survive and replicate within their natural protozoan hosts. Humans serve as an accidental host for Legionella species after inhalation of contaminated aerosolized water droplets or soil particles enabling the bacteria to enter the lungs, infect alveolar macrophages, and result in severe pneumonia. Evasion of degradation and proliferation within alveolar macrophages by Legionella species and manifestation of “Legionnaires’ disease” is dependent on the Dot/Icm type IV secretion system (T4SS). The T4SS apparatus is a needle-like channel for translocation of over ~350 effector proteins, depending …

Comparison Of The Effect Of Heavy Pulls Vs Light Powers On A Subsequent Clean In Trained Athletes, Luke Devirgiliis

Electronic Theses and Dissertations

The sport of weightlifting has been competed since the first modern Olympiad. Competition in weightlifting consists of 3 attempts the snatch and clean and jerk declared by the athlete and their coach prior to the starting of the lift. While waiting for the athlete’s lift, waiting periods can change and warm up attempts may need to be adjusted. Often, coaches prescribe either a complete “light power” or partial “heavy pull” repetition of the competed movement during a long wait. Previous literature indicates that a heavier stimulus may cause a “post-activation potentiation”, or “post-activation performance enhancement” effect on the subsequent lift. …
