For more than 15 years, the 麻豆传媒鈥檚 Center for Lung Biology has sought to advance the understanding of human health and disease while improving patient care and creating a state-of-the-art training environment for tomorrow鈥檚 clinicians and researchers.

Along the way, the center鈥檚 collaborative spirit has propelled it to the forefront of South鈥檚 translational research efforts to move research from bench to bedside.

From studying acute lung injury and pulmonary hypertension to airways, blood vessels, pulmonary endothelial cell and nano-scale respiratory cell biology, the center鈥檚 more than 40 faculty members and 25 postdoctoral fellows, clinical fellows and graduate students advance their respective fields and lend perspective and resources across program and department lines. To date, those efforts fuel everything from the search for definitive pulmonary hypertension biomarkers to aiding in the fight against antibiotic-resistant bacteria.

鈥淲e are fortunate to have some of the world鈥檚 leading pulmonary scientists and clinicians right here at 麻豆传媒. Our faculty and trainees are making great strides toward a better understanding of acute and chronic forms of lung disease and, based on this work, developing new biomarkers of disease and therapeutic options for the patients our clinicians serve,鈥� said Dr. Troy Stevens, professor and Lenoir Louise Locke Chair of Physiology and Cell Biology at the 麻豆传媒 College of Medicine and director of the 麻豆传媒 Center for Lung Biology.

The center鈥檚 work recently was bolstered by a $9.9 million five-year grant renewal from the National Institutes of Health.

Translational research in the simplest terms means applying laboratory- and preclinical study-discoveries to the development of clinical trials to engage community patient populations.

Consider, for instance, the work of Dr. Natalie Bauer, whose research represents the bench end of the translational research spectrum. Bauer, an associate professor of at the 麻豆传媒 College of Medicine, studies pulmonary hypertension, a progressive disease in which high blood pressure in the lungs leads to heart failure. She was recently awarded a four-year, $1.5 million grant from the National Institutes of Health to study how circulating factors contribute to pulmonary hypertension.

Through this new grant, Bauer is studying extracellular vesicles called microparticles that, despite their diminutive size, carry volumes of information about their source cells, such as the endothelial cells that line blood vessels.

鈥淲hat we found in the model of the disease is that these microparticles can induce an inflammatory response that is specific to the pulmonary circulation. We also found they don鈥檛 seem to interact as much with the rest of the body, so now we鈥檙e trying to translate that with blood samples,鈥� she said.

Enter Dr. Karen Fagan on the bedside end of the translational research spectrum with access to patients who are willing to contribute their blood samples to Bauer鈥檚 research. Fagan is the director of 麻豆传媒 Health鈥檚 pulmonary and critical care division and director of the Pulmonary Hypertension Center.

鈥淲e鈥檝e got the only pulmonary hypertension center on the northern Gulf Coast, so having this amazing collaboration with Natalie gives us an opportunity to learn about the disease, help predict who is going to do well or not, and ultimately better understand the biology of the disease,鈥� said Fagan, who also holds an appointment to the Center for Lung Biology.

Bauer said, 鈥淭he goal is to see if we see the same responses with human samples and lab samples. We鈥檙e trying to determine if microparticles from human cells do the same thing we鈥檝e seen them do in rat cells.鈥�

Moreover, Bauer is attempting to determine if the microparticles can ultimately serve as a biomarker for pulmonary hypertension, which remains difficult to diagnose.

鈥淚 couldn鈥檛 move my work forward in this way without collaborating the way I have with Dr. Fagan, and that鈥檚 why I think the 麻豆传媒 Center for Lung Biology provides an excellent environment for practicing translational medicine,鈥� Bauer said. 鈥淢aybe the physician scientist you work alongside inspires you to formulate an entirely different question that will truly help the patients. In the end, that鈥檚 everyone鈥檚 goal 鈥� figuring out what provides the best outcomes for the patients 鈥� and that鈥檚 why this approach works.鈥�

Fagan, a professor of medicine and pharmacology, said the potential long-term developments for pulmonary hypertension patients are promising.

The ultimate goal is to develop new treatment plans and therapies that benefit patients and improve outcomes; occasionally there is the added bonus of witnessing a lab-born theory play out in real time with real patients.

鈥淥n our side, we work with the basic science researchers to develop research protocols and plans to identify those opportunities,鈥� Fagan said.

In addition to advancing science and medicine, the Center for Lung Biology also supports the University鈥檚 education mission. Ph.D. candidate Sarah Voth called the working environment within the center 鈥渆xceptionally collegial鈥� and characterized collaboration as 鈥渋ntegral to our ethos.鈥�

鈥淏oth intra- and interdepartmental collaborations are quite common and highly encouraged. I believe this not only promotes rapport but greatly strengthens the quality of each individual investigator鈥檚 work through the incorporation of interdisciplinary perspectives and expertise,鈥� said Voth, a predoctoral fellow in the lung biology track of the Basic Medical Sciences program in the College of Medicine.

Voth studies host pathogen interactions in the context of hospital-acquired pneumonia. Her research is 鈥減roving readily translatable to the clinic鈥� in terms of pursuing development of broad-spectrum adjuvant therapies targeting hospital-acquired infections, as well as yielding 鈥渟everal readily available strategies for acute interventions for critically ill patients with nosocomial pneumonia.鈥�

She said her training within the Center for Lung Biology has been critical to her education and professional development, all made possible via a National Institutes of Health T32 Training Grant through the center that has financed her stipend, books, software, project materials and research-related travel.

鈥淭rainees in the Center for Lung Biology have the opportunity to learn from and interact with lead investigators and top medical scientists representing a wide variety of lung biology subspecialties,鈥� Voth said. 鈥淭his gives us a broad and rigorous background in the science, methods and perspectives relevant to the field that would not have been possible otherwise. The faculty truly are devoted to helping each student achieve their individual potential and career goals and readily make time to go above and beyond.鈥�
