Show moreWith the use of combinatorial phage display, solid phase peptide synthesis and a multidiscipline of molecular and cellular assays in vascular biology, the research described in this thesis has resulted in the identification of two novel peptides targeting to SR-AI and CD40 respectively which hold promise as targeted contrast agents for the diagnosis of atherosclerosis symptom. In addition, a peptide named VIVIT and its derivatives had been discovered and synthesized which constitute a more selective and less toxic drug candidate than currently used immunosuppressant cyclosporine A or FK506, leading to new generation immunosuppressants and therapeutics for autoimmune diseases such as rheumatoid arthritis or allograft transplantation and cardiovascular disorders including atherosclerosis, restenosis and cardiac hypertrophy.
