英文摘要
DESCRIPTION (provided by the applicant): Acute inflammation is necessary for
host defense but can also cause organ injury and dysfunction. The NF-kB
transcription factor complex is critical for regulation of acute inflammation
by controlling expression of a number of key cytokines, adhesion molecules and
enzymes. We have generated transgenic mice that express Photinus luciferase
under the control of an NF-kB dependent promoter. In this proposal, we
hypothesize that our transgenic luciferase reporter mice represent a powerful
tool for non-invasive in vivo measurements of NF-kB dependent inflammatory
responses and that these animals can be used as a tool for high-throughput
screening of anti-inflammatory compounds. We propose 2 specific aims: 1) to
optimize repetitive, non-invasive measurement of NF-kB activation using intact
transgenic luciferase reporter mice, and 2) to validate the utility of this
system for screening NF-kB inhibitors using a mouse model of bacterial
lipopolysaccharide-induced lung inflammation. Currently available methodologies
for screening anti-inflammatory compounds involve initial in vitro studies
followed by studies involving large numbers of animals. Our methodology
represents a marked improvement in this process by using each mouse as its own
control and allowing multiple measurements overtime. These improvements should
allow initial testing in mice, thus simplifying and accelerating the process of
anti-inflammatory drug development.
PROPOSED COMMERCIAL APPLICATION:
Identification of new agents with potential as anti-inflammatory therapeutics requires
screening in animal models, but current models are labor intensive and inefficiect as
screening tools. Since activation of NF-kB is common to pathogenesis of a host
of diseases characterized by neutrophilic inflammation, an in vivo method for rapid
determination of NF-kB would be a valuable screening tool. We propose to refine a
mouse model in which non-invasive, serial, quantitative, organ specific measurements
of NF-kB activation can be made. The model would be highly valuable to pharmaceutical
companies and other developing anti-inflammatory therapeutic agents as a high throughput
screening tool for identifying potentially efficacious agents and defining anti-inflammatory
pharmacockinetics.
