Explanation:
The immune system is an efficient and powerful biological machine. It protects us from millions of germs and fights off viruses and infections. So powerful are its responses that they may cause fevers, aches and pains, inflammation and swelling. "It's because your immune system is ramping up—it's doing what it's supposed to do," Dr. Lynch says. And what it does is more than fight off disease. Researchers at Northwestern University have concluded that immune cells known as macrophages stimulate cells in the heart muscle, helping to keep the heart pumping and maintain a steady beat. Swedish researchers have also found evidence that immune cells clear out dead brain cells after a stroke and secrete substances that may allow the brain to repair damage. At the same time, though, scientists are learning how cancer cells not only evade the immune system’s defenses, but actually use immune cells to facilitate their attack on the body.
Our immune cells are typically very good at recognizing altered or foreign cells and swiftly dispatching them. But in the case of a tumor, they seem to turn a blind eye.Unexpectedly, we found that the immune system could not destroy cells expressing even highly immunogenic neoantigens when they were found at low abundance,” says Ron Gejman, an MD/PhD student in the Scheinberg lab and the paper’s first author. “Somehow, these clearly altered cells are being missed.”
He says that the results help explain why cancer cells that the immune system theoretically could kill ultimately manage to escape destruction. The findings might even point to why tumors form in the first place.We know very little about which neoantigens are recognized by the immune system,” says Dr. Scheinberg, Chair of the Molecular Pharmacology Program in the Sloan Kettering Institute and Director of the Center for Experimental Therapeutics at MSK. “When we started this work, it was to learn what makes a good neoantigen when it comes to eliciting an immune response.”
