The body consists of cells which communicate with each other via signaling molecules to govern and determine a variety of physiological functions in the body. The action and effect of these signaling molecules is mediated by ‘receptors’ which are located on the surface of (plasma membrane), or inside a cell. A molecule that ‘binds’ with a receptor is known as a ligand and can be protein such as a hormone or drug and the role of the ligand is to activate, or inactivate a particular biological activity.
In some ways receptors can be likened to switches with on and off positions, and which in turn affect the cell’s internal functioning. The action or inaction of receptors is determined by the type of ligand with which they bind, i.e. receptors are activated when an agonising ligand, an ‘agonist’ binds and left inactive when an ‘antagonist’ in some way prevents the agonist from binding. The specific biological action is dependent upon which particular ligand binds with a receptor.
As many of you may know, this week saw Clinuvel hold its Annual General Meeting in the Melbourne Town Hall. As managing director I welcome these opportunities where I am able to meet and talk to the people whom Clinuvel considers integral to the company and its existence; the Board of Directors sees Clinuvel’s investors as unique. In Clinuvel, an investor has to fundamentally believe in the premise of offering pharmaceutical photoprotection, a novel option, an innovative approach to skin disorders.
Those of you that follow pharmaceutical development and Clinuvel in particular will know that we recently presented at Rodman and Renshaw’s 11th Annual Healthcare Conference in New York. It’s serendipitous that the following week found another conference taking place in the same city, although involving a rather different topic. The coincidence draws attention to a connection that is of increasing urgency and importance.
