<<Disclaimer: Verify this information before applying it to your situation.>> I've just been reading the latest issue of Lab Business (a Canadian magazine targeting laboratories and lab suppliers) and there is a short note about a discovery by several collaborating groups in the Toronto area. They have discovered that a protein called CD45 acts as an "off switch for several disease signals, including cancer, heart disease and autoimmune diseases". The discovery, the note says, could "lead to a more targeted way to control diseases such as cancer, diabetes and heart disease by turning off the communications signals that order the immune system to go on the offensive". This research was headed by Dr. Josef Penninger and was apparently featured in a recent issue of Nature. Steve Schroeder email: [log in to unmask]
