LSU Health research laboratory.



Welcome to the Department of Pathology Division of Research, which consists of the laboratories of Dr. Guillermo Herrera, Dr. A. Wayne Orr, Dr. Chris Kevil, Dr. Shenuarin Bhuiyan, Dr. Jiamin Teng, and Dr. Xinggui Shen. From a basic science perspective, our combined research explores cell-matrix interactions, cell signaling, biochemical redox biology, and regulation of autophagy in chronic inflammation and in renal and cardiovascular remodeling. These basic science themes are translated to the study of the initiation and progression of complications resulting from long term diabetes mellitus, including atherosclerosis, nephropathy, cardiac failure, and ischemic vascular disease. Funding for our research programs comes from NIH (NIDDK, NHLBI), the American Diabetes Association, and the American Heart Association.

The Division of Research sponsors a weekly “Molecular Basis of Disease Journal Club” and a biweekly “Research in Progress” Division meeting. The Division also sponsors a monthly Seminar Series, which has rapidly become recognized throughout LSU Health-Shreveport for its excellence in recruiting “cutting edge” extramural speakers to participate in the Series. The Division provides research opportunities for Medical Students as well as Residents and Fellows from the Department of Pathology and other clinical departments. In addition, the Division provides research training for a number of Post-doctoral Fellows and for Graduate Students from the Departments of Cell Biology and Anatomy and Molecular and Cellular Physiology.
