Research in Cellular Engineering

The research we do in our lab is in the area of cellular engineering. We use a variety of engineering tools to analyze reactions that occur on the surface of cells and/or within cells to try to understand the mechanism of various diseases. We then use that information to try to alter the selectivity of those reactions such that we prevent or slow the progression of disease. For example, some proteins, such as beta amyloid of Alzheimer's disease, interact with neurons. If the protein is in a normal or "healthy" conformation, the interaction is benign, while if the protein is in its amyloid or "pathogenic" conformation, the protein-cell interaction leads to cell death. We would like to understand the mechanism of the protein-cell interaction and be able to prevent it.

The following students have worked with me (either advised or co-advised) towards their graduate degrees: 

 I am always looking for independent, resourceful and creative people to join the lab to work on all aspects of challenging and important problems associated with human disease.  But there should also be time for enjoying all aspects of life in graduate school.Jennifer sailingIrina Ramos, SailingDhara Sailing

We have several ongoing research projects....
Engineering of Drug Delivery to T Cells

T cells are one of the cellular components of the immune system. Inappropriate stimulation of a T cell by a normal protein results in healthy tissue destruction. This mechanism is thought to be responsible for a number of diseases, including some forms of arthritis and diabetes. We are constructing  mathematical models of T cell response and using them to help in the design of antisense and photodynamic therapies to treat T cell diseases.

Exploration of the Role of Biomechanical Forces in Neurodegeneration

A number of diseases affecting central nervous system tissue, such as glaucoma, head injury, and hydrocephalus, are characterized by elevation of intraocular or intracranial pressure and/or local shear stress and strain. We propose that the neurodegeneration in these diseases is a direct result of the local shear stress and strain acting on neurons. My students are developing an in vitro model of shear stress and strain induced neurodegeneration which can be used to elucidate steps in the mechanism of shear stress and strain induced neurodegeneration and to test new compounds for the treatment of diseases such as glaucoma and head injury.

Protein Aggregation and Amyloid Diseases

At least 16 different human proteins can fold abnormally resulting in the formation of an amyloid fibril and some accompanying pathology. Two of the best known examples of these diseases are Alzheimer's disease and transmissible spongiform encephalopathies (such as Mad Cow disease). We are investigating the mechanism by which amyloid-forming proteins cause neurodegeneration and exploring the relationship between peptide structure and biolgoical activity. We are also developing biomimitic polymers as potential therapeutics for use in the prevention of amyloid toxicity.  Our research could lead to the development of cures for these otherwise fatal diseases.  In addition, we, along with Dr. Gerard Cote’ from Texas A&M University, are trying to exploit our knowledge of these disease causing proteins to develop novel sensors for various amyloid diseases.
