Interests and Research Activities

Dr. Sabbadini was a Professor of Biology for 32 years at San Diego State University and is currently Emeritus Professor of Biology. He founded three biotechnology companies, including Lpath, Vaxiion and Mpex, incubated out of SDSU.  Dr. Sabbadini has been interested in the role of bioactive lipids in disease, including cancer, ocular disorders, neurotrauma, neuropathic pain, inflammation and heart disease.  Dr. Sabbadini’s research focused on developing novel antibody-based therapeutics against bioactive lipids such as the sphingolipid, S1P and LPA. The anti-S1P antibodies are in clinical trials for AMD and cancer. Sphingolipids multifunctional lipid mediators largely involved in signaling activities required for normal cellular function.  However, bioactive lipids can become dysfunctional and directly contribute to the pathophysiology of diseases.
