Erythrocyte Aggregation And Neutrophil Function In An Aging Population, Rhys Christy, Oguz Baskurt, Gregory Gass, A. Gray, Sonya Marshall-Gradisnik
A. Bon Gray
There are limited investigations which have examined the relationship between neutrophil activation and erythrocyte aggregation in older persons. The purpose of the present study was to investigate the relationship between neutrophil activation and erythrocyte aggregation (EA) in an aging population. Twenty-eight male and female subjects were allocated into one of four groups with 7 participants in each group (group 1, 20–29 years; group 2, 30–39 years; group 3, 40–49 years; group 4, 50–59 years). EA was determined using the Myrenne aggregometer. Neutrophil function (respiratory burst and phagocytic activity) was assessed using flow cytometry. EA was found to increase with age. …

Host-Pathogen Interactions Of Secreted And Surface Staphylococcus Aureus Factors, Vanessa Vazquez
Dissertations & Theses (Open Access)
Staphylococcus aureus is an opportunistic bacterial pathogen that can infect humans and other species. It utilizes an arsenal of virulence factors to cause disease, including secreted and cell wall anchored factors. Secreted toxins attack host cells, and pore-forming toxins destroy target cells by causing cell lysis. S. aureus uses cell-surface adhesins to attach to host molecules thereby facilitating host colonization. The Microbial Surface Components Recognizing Adhesive Matrix Molecules (MSCRAMMs) are a family of cell-wall anchored proteins that target molecules like fibronectin and fibrinogen. The Serine-aspartate repeat (Sdr) proteins are a subset of staphylococcal MSCRAMMs that share similar domain organization. Interestingly, …
