Research

Our laboratory's research focus is on exploring unique attributes of nanotechnology to find effective therapy for diseases that are difficult to treat, or for which there is no treatment. We investigate, design, develop, and evaluate potential new "nanomedicines," with the ultimate objective of translating our research from bench to bedside.

In our current research projects, we aim to: (a) understand the role of epigenetic changes in tumor drug resistance and metastasis and create nanotherapeutics to treat both primary and metastatic tumors; (b) explore effective therapies for stroke, particularly methods of preventing reperfusion injury and facilitating neurological repair mechanisms; (c) investigate novel neuroprotective and regenerative therapies for spinal cord injury and blast-associated traumatic brain injury; (d) develop a balloon-based delivery system for treating peripheral artery disease; and (e) find a treatment that can delay photoreceptor degeneration in retinitis pigmentosa.

We are innovative and active in developing new intellectual property, as well as in the patenting, licensing, and commercialization of our technologies to ultimately benefit patients. Our research is funded primarily by the National Institutes of Health and the Department of Defense.

Neuroprotective Nanoparticles for treating CNS injuries: We began investigating the efficacy of unique neuroprotective nanoparticles in CNS injuries, particularly in stroke and spinal cord injury. We recently expanded my research into the area of blast wave-associated traumatic brain injury (bTBI), a significant issue for the military. Our overall therapeutic strategy is to inhibit the progression of the secondary injury cascades of degenerative events that follow the primary injury and promote the endogenous brain-repair mechanisms. Our recent and ongoing studies have demonstrated that delivery of neuroprotective nanoparticles at the time of reperfusion in a stroke model is effective in minimizing the damage due to ischemia/reperfusion injury, leading to neuronal regeneration and functional recovery over time.  We are now expanding our research to other types of CNS injuries.

Epigenetic cancer nanotherapy and cancer drug resistance/metastasis: We have been studying nanoparticles for cancer nanomedicine, particularly as a drug-/gene-delivery system to overcome resistance to chemotherapy drugs. Our laboratory’s recent focus has been on understanding the role of epigenetic changes in cancer drug resistance and tumor metastasis. In this regard, we have been investigating epigenetic nanotherapy for treating resistant and metastatic breast tumors. We are also examining the role of epigenetics in breast cancer stem cells and testing the approach of reprogramming them with epigenetic drugs to make them more susceptible to conventional anticancer drugs.

Cellular uptake and intracellular trafficking of nanoparticles: My laboratory has extensively investigated the mechanism of cellular uptake of nanoparticles (NPs) and their intracellular trafficking.  We first discovered that poly lactic co-glycolic acid (PLGA) NPs rapidly escape endosomes following their cellular uptake, but in our subsequent studies, we found that only a small fraction of the internalized NPs escape endosomes and are retained by cells. A major fraction (85%) of these internalized NPs remains in recycling endosomes and undergoes exocytosis. This observation led us to further studies to understand the role of NP surface characteristics on cellular uptake, endosomal escape, and retention.

Role of biophysics of membrane lipids in drug delivery: We found that biophysical interactions of nanoparticles (NPs) depend on both biophysical (e.g., membrane fluidity) properties of membrane lipids and NP characteristics (interfacial properties). Recently, we determined that biomechanics (bending force) and thermodynamics (“Gibbs free energy”) of interactions of NPs with cell membrane lipids play an important role in endocytosis and escape of NPs from endosomes. We also found that selective biophysical interaction of NPs with the membrane lipids of cancer cells vs. normal cells could be developed as a new targeting approach for drug/gene delivery.
