I discovered 2 new white cells in the immune system. They are called M1 and M2 macrophages which are Killer or Repair cells, respectively. It is not M because I am Mills as I am sometimes kidded. Now, M1 and M2 are the terminology used worldwide. Because of this discovery, I was invited to be the Editor of a Research Topic at Frontiers in Immunology. I thought some might enjoy seeing a description of the Topic.
