A College of Medicine researcher has received a prestigious U.S. National Science Foundation CAREER Award to support her research into the cellular causes of inflammation, discoveries that could be pivotal for treating conditions like Crohn\u2019s disease and arthritis.<\/p>\n
Justine Tigno-Aranjuez\u2019s lab has been researching lipid mediators \u2014 bioactive lipids the body produces in response to stimuli such as microorganisms or microbial products. Scientists have long known that lipid mediators can influence both the initiation and resolution of inflammation. However, the exact mechanisms by which this happens are still not completely understood.<\/p>\n
She will use her five-year grant of more than $1 million to study how a specific receptor and cellular signaling pathway, known as NOD2, influences the production of lipid mediators with the goal of better understanding its impact on inflammation.<\/p>\n
\u201cThe NOD2 pathway has been widely studied, in part, because of its well-known genetic links with inflammatory diseases like Crohn\u2019s Disease and Early Onset Sarcoidosis,” Tigno-Aranjuez says. “Most of the focus has been on the events which promote the production of inflammatory cytokines, another type of protein-based signaling molecule. There are very few studies looking into how exactly activation of the NOD2 pathway can lead to the production of lipid mediators. Our hope is that by understanding the molecular events important for the production of such lipid mediators, we can guide therapies in the future that either prevent inflammation or promote its resolution.\u201d<\/p>\n
Today, nearly 35% of US adults suffer from chronic inflammatory disease. Inflammation occurs as a part of the body\u2019s natural immune response. When a foreign substance like a virus or bacterium enters your body, it cues production of cytokines and lipid mediators that recruit inflammatory cells to control the infection. Later, the body produces other to promote healing and the clearance of dead cells.<\/p>\n
However, if the body incorrectly starts inflammation when no foreign object is present, or doesn\u2019t stop the inflammatory process once the danger is over, patients can develop chronic illness.<\/p>\n
\u201cIn the past, researchers believed that when something caused inflammation, let\u2019s say you get poked with something or infected with a microbe, when you take that away, everything will go back to normal,\u201d Tigno-Aranjuez says. \u201cBut what researchers have found out is there are\u00a0 a lot of factors that go into bringing us back to baseline, including the active production of certain classes of lipid mediators and that\u2019s why it\u2019s important that we understand how they are produced.\u201d<\/p>\n
Every year, hundreds of researchers apply for the NSF\u2019s CAREER Award which support early-career faculty who they see as potential role models in education and research. With only about 50 given out this year, Tigno-Aranjuez says she was honored and grateful for the award.<\/p>\n
\u201cThis was one of my long-standing pet projects. It wasn\u2019t the original focus of the lab when I started, but it was something that I was really interested in pursuing and taking further. So, to see it now funded and recognized is really important.\u201d she says.<\/p>\n
This grant will also offer UCF undergraduates a sustained research experience to prepare them for future careers in the sciences and in medicine.<\/p>\n
\u201cThe grant will support a Sustained Research Initiative, which I am hoping will open up a lot of opportunities for undergraduates to get hands-on research in a controlled setting.\u201d she says. \u201cStudents will be working both as individuals and as a team in research labs, and, if they do really well, will have the opportunity to serve as an instructor for future students.\u201d<\/p>\n
Tigno-Aranjuez immigrated to the United States from the Philippines to conduct her graduate and postdoctoral training at Case Western Reserve University in Cleveland. She joined UCF in 2015 and focuses her research on innate immune signaling pathways involved in chronic inflammatory diseases.<\/p>\n","protected":false},"excerpt":{"rendered":"
