Cell & Developmental Pathology

Fundamental studies in the area of cell and developmental pathology focus on the development, morphogenesis and function of epithelial, hematopoietic and neuronal cell lineages as well as cells of the immune system.

Cell-to-cell adhesion molecules' integration of mechanical and signaling functions in skin and heart differentiation, disease and cancer.

Research Description

Dr. Green's research program focuses on how cell-cell adhesion molecules and their associated proteins integrate mechanical and chemical signaling pathways to contribute to the development and maintenance of multicellular tissues. In particular they are investigating how specialized intercellular junctions called desmosomes are assembled and function in ways that transcend their classic textbook definition as spot welds. The lab has shown that desmosomal cadherins help control the balance of proliferation and differentiation and even regulate the production of cytokines that participate in paracrine signaling. Loss of this “brake” results in increased allergic and inflammatory pathways that underlie pathogenesis in inherited disease and possibly cancer, including melanoma. Desmosomes also integrate the functions of other intercellular junctions including gap junctions and interfering mutations can cause lethal heart arrhythmias.

The lab uses a multi-faceted approach, including but not limited to collaborative atomic structure determinations, molecular genetics, live cell imaging, human tissue engineering and gene targeting approaches. Dr. Green serves as Associate Director for Basic Sciences in the R.H. Lurie Comprehensive Cancer Center.

 Yashpal Kanwar Lab

Principal Investigator: Yashpal Kanwar, MD, PhD
Research Interest: Pathology of diabetic nephropathy with an emphasis on tubulopathy

We study how the association of cells with the extracellular matrix-rich environment guides the morphogenesis of tissues and contributes to repair after injury, leading to the development of fibrosis in the kidneys in response to aging, gene mutations and changes in metabolism. 

Our lab is interested in how cytoskeletal signaling, motor proteins and adhesion systems are integrated with chemical signaling pathways to regulate cell behavior and tissue differentiation and disease.  Specifically, we are interested in the role of small G proteins and their regulatory GEFS and GAPs in kidney, skin and cardiac development and disease including diabetic nephropathy.

 Peng Ji Lab

Role of MDia1 in the pathogenesis of del(5q) myelodysplastic syndromes

Research Interests

Our lab is interested in how cytoskeletal signaling, motor proteins and adhesion systems are integrated with chemical signaling pathways to regulate cell behavior and tissue differentiation and disease. The Ji lab studies small G proteins and downstream actin regulatory effectors that participate in enucleation during red cell development.

At the level of the nucleus, the Ji laboratory studies genes involved in erythroid lineage commitment, chromatin condensation and enucleation towards understanding how congenital red cell disorders and leukemia develop.
