Reading this enjoyable review by Anthony van den Pol about neuropeptides, wondering if you are investigating peptides too, and what fascinates you about them? For example, I am fascinated about the tonic release of certain peptides and wonder how there is sufficient receptor at the cell surface for continuous interaction. What is it about peptides that intrigues or interests you?
