RECENT RESEARCH ACTIVITIES
A 3D Vascular Tissue Model for Studying the Link Between Diabetes and Atherosclerosis
We are using a 3D human in vitro tissue model that recapitulates the interface between a blood vessel and the surrounding tissue to mimic an allergic inflammatory response. As an allergy sensor, the tissue model can be comprised of patient-specific cells and be used to predict a patient’s response to allergies, possibly better than existing clinical tests, such as the allergy skin test.
An Advanced Tissue-Equivalent Respiratory Model to Study Airway Reactivity to Infectious Agents
We are using a tissue-equivalent respiratory model that exhibits a normal immunological response against infectious agents, such as the influenza virus, to determine the mechanisms that lead to an excessive inflammatory response and ensuing complications.
A Novel Ophthalmic Drug Delivery System for the Treatment of Diabetic Retinopathy
To improve sustained delivery of drugs to the eye, we have designed a novel system that includes drug-loaded nanoparticles suspended within a thin membrane that can be attached to a standard commercial-grade contact lens for support. The lens system will provide constant contact with the eye’s surface and the particles will supply a continuous release of medication, resulting in more drug reaching the target.
