Researchers have focused on white blood cells called T cells while looking for a cure. T cells are a part of the immune system the virus uses as a host. Recently researchers have discovered that this virus can be found not only in T cells but also in large white blood cells found in different tissues in the body called macrophages. This is a big discovery because it shows that T cells are not the only cells the virus can infect. For a cure to be found, researchers now have to look for therapeutic interventions that target two different cells. I think this is a big deal because finding a cure is now going to take longer since researches have to target multiple types of cells.
