PROFESSOR SIAHAAN's research interests are in the utilization and modulation of cell adhesion molecules on the cell surface for targeted drug delivery to a specific cell type and for enhancing drug permeation through the intestinal mucosa and blood-brain barrier (BBB). Currently, his group is using peptides derived from cell adhesion molecules (i.e., ICAM-1 and LFA-1) to target drugs to leukocytes and vascular endothelial cells in inflammatory and autoimmune diseases (i.e., rheumatoid arthritis). Cell adhesion peptides are being used to target antigenic peptides (i.e., bi-functional peptide inhibitor (BPI)) to block the formation of the immunological synapse at the interface between T cells and antigen presenting cells (APC). BPI molecules have been shown to suppress autoimmune disease models such as type-1 diabetes and multiple sclerosis. Finally, Dr. Siahaan’s group is using E-cadherin peptides to enhance permeation of large hydrophilic molecules (i.e., peptides and proteins) through the intestinal mucosa and BBB. The hypothesis is that E-cadherin peptides modulate the E-cadherin interactions at the intercellular junctions to create larger openings that will allow paracellular permeation of large hydrophilic molecules (e.g., peptides and proteins).
