Curbing blood cancers by teaching immune cells to kill mutant stem cells
Blood stem cells, which give rise to all of our blood cell types, undergo a quality assurance process after they’re born. As the lab of Leonard Zon, MD, director of the Stem Cell Research program at Boston Children’s, has documented, immune cells known as macrophages interact with each newly born cell. They engulf and eat ... Read More about Curbing blood cancers by teaching immune cells to kill mutant stem cells
A new anti-cancer strategy: Overriding tumor edits
Cancers are clever and often find ways to dodge people’s immune systems, making them hard to eradicate. Immunotherapies such as CAR-T cells and checkpoint inhibitors can sharpen the immune system’s attack and cure the cancer. But they don’t work for most solid tumors. We now know that tumors can edit their genes to evade immune ... Read More about A new anti-cancer strategy: Overriding tumor edits
Immunotherapy for children with primary liver carcinomas: Research offers new hope
Pediatric hepatocellular carcinoma (HCC) and fibrolamellar carcinoma are rare, aggressive forms of liver cancer that typically affect adolescents and young adults. Although some immunotherapy drugs are approved by the Food and Drug Administration as first-line treatments for HCC in adults, less is known about their effectiveness in treating pediatric liver carcinomas. Now, new research led ... Read More about Immunotherapy for children with primary liver carcinomas: Research offers new hope
After surgery for a brain tumor, Jenny is moving ahead — and giving back
“It might sound weird,” says Jenny Eckert, “but I’m very grateful that I got hit in the face with a soccer ball.” A year and a half ago, Jenny, then 9, was playing soccer when she accidentally took a hit to the head — twice. Concerned about a possible concussion, her parents, Vanessa and Scott, brought ... Read More about After surgery for a brain tumor, Jenny is moving ahead — and giving back
Boosting vaccines for the elderly with ‘hyperactivators’
As we age our immune systems start to flag, leaving us more susceptible to cancer and infections — and less responsive to vaccines and cancer immunotherapies. Going to the heart of the problem, Jonathan Kagan, PhD, a researcher in immunology at Boston Children’s Hospital, has identified a way to rejuvenate the elderly immune system. His ...

Exposing a tumor’s antigens to enhance immunotherapy
Successful immunotherapy for cancer involves activating a person’s own T cells to attack the tumor. But some tumors have a trick: They hide themselves from the immune system by preventing their antigens from being displayed, a necessary step in activating T cells. In new work published in Science, researchers in the Program in Cellular and ... Read More about Exposing a tumor’s antigens to enhance immunotherapy
Combining CAR-T cells and inhibitor drugs for high-risk neuroblastoma
Chimeric antigen receptor (CAR)-T cell therapy is a potent emerging weapon against cancer, altering patients’ T cells so they can better find and destroy tumor cells. But CAR-T cell therapy doesn’t work well in every cancer — including many cases of neuroblastoma, a cancer that begins in young children’s nerve tissue and can metastasize to ...

Could a GI bug’s toxin curb hard-to-treat breast cancer?
Clostridium difficile can cause devastating inflammatory gastrointestinal infections, with much of the damage inflicted by a toxin the bug produces. But research from Boston Children’s Hospital suggests that the same toxin could also be a useful tool for curbing highly aggressive triple-negative breast cancers that don’t respond to chemotherapy. Min Dong, PhD, in the Department ... Read More about Could a GI bug’s toxin curb hard-to-treat breast cancer?
Making immunotherapy safe for AML
Acute myeloid leukemia (AML), the second most common leukemia in children, is hard to treat and has a five-year survival rate of just 65 to 70 percent, according to the American Cancer Society. While immunotherapies like monoclonal antibodies or CAR T-cell therapy are effective for certain blood cancers, they have not been possible in AML ...

All eyes on retinoblastoma: How Lyla and her mom are helping change lives
Meghan Landry firmly believes that art saved her daughter Lyla’s life. Now, she hopes to leverage the power of creativity to help support other kids like Lyla, who was diagnosed with retinoblastoma at 18 months old. Meghan, who lived in Florida at the time, was waiting with Lyla for a routine pediatrician appointment when she ...
