Thermal Burn Injury Induced Microvesicle Particle Release, Katherine Erin Fahy

Browse all Theses and Dissertations

Microvesicle particles (MVP) are found to be important for cellular communication because they contain many bioactive proteins, lipids, cytokines, and nucleic acids. We have previously found that ultraviolet B radiation (UVB) and a Platelet-activating factor agonist (CPAF) can stimulate the release of MVP in keratinocytes. We hypothesized that there may also be an increase in MVP released after thermal burn and that could be involved in pathogenesis of the systemic effects found in some patients. In this thesis various keratinocyte cell lines, mice and human ex vivo skin were used as model systems to test our hypotheses. It was determined …
