Scientists discover how to change Leukemia cells into Immune cells

A team at Stanford's School of Medicine has reportedly uncovered a potent new treatment method for combating one of leukemia's most aggressive forms. While survival rates for B-cell acute lymphoblastic leukemia, a particularly nasty form of white blood cell cancer, have risen to about 85 percent over the past decade thanks to the advent of stem cell therapies, the prognosis for this disease in the presence of a Philadelphia chromosome mutation remains quite poor. Due to a chance observation by Dr. Scott McClellan, the Stanford team believes it's figured out way to neutralize the disease using its own cancerous cells against it.
Dr. McClellan noticed that a number of leukemic cells had transformed from cancerous cells into "mature" macrophages. These are a type of immune cell tasked with not only directly consuming cellular debris, pathogens and cancers but also with recruiting other immune cells for the fight. "B-cell leukemia cells are in many ways progenitor cells that are forced to stay in an immature state," Dr. Ravi Majeti, an assistant professor of medicine at Stanford, said in a statement. But with the addition of various transcription factors, proteins capable of latching onto and activating specific DNA sequences, Majeti and McClellan essentially forced these deadly cancer cells to "grow up" into fully formed macrophages.
What's more, the researchers discovered that this process didn't just neutralize that specific cancer cell. It also directed the newly made macrophage to begin digesting the cancerous plague and fire-up the rest of the immune system to fight the mutation. "Because the macrophage cells came from the cancer cells, they will already carry with them the chemical signals that will identify the cancer cells, making an immune attack against the cancer more likely," Majeti said.
