project title:
the role of integrin receptors in pseudomonas aeruginosa infection of human lung epithelial cells.
rebecca's general area of study:
pseudomonas aeruginosa is a major pathogen involved with ventilator associated pneumonia and cystic fibrosis. we are interested in investigating the role of integrins receptors in pseudomonas aeruginosa adherence to and invasion of lung epithelial cells, and the cell signalling events initialized as a result of these interactions. to study the host-pathogen interactions, we have stably genomically labelled the bacterium pseudomonas aeruginosa strain pak with a green fluorescent protein gene (gfp) that allows for detection and visualization of the bacterium using fluorescence based readouts. the importance of integrins in adherence, internalization, and inflammatory signalling initiated by pakgfp can be measured by using various methods of inhibiting integrins and comparing the response of the epithelial cells.
