Gasdermin E: A new approach to cancer immunotherapy
Tumors have figured out various ways to prevent the immune system from attacking them. Medicine, for its part, has fought back with cancer immunotherapy. The major approach uses checkpoint inhibitors, drugs that help the immune system recognize cancer cells as foreign. Another method, CAR T-cell therapy, directly engineers peoples’ T cells to efficiently recognize cancer ... Read More
S1P and its receptor: New approaches to cancer?
In 1998, when Timothy Hla, PhD, and his colleagues identified and cloned the receptor for sphingosine-1-phosphate (S1P), it generated a lot of excitement. S1P, a lipid originally discovered in the 1960s, was known to play various roles in the body and in disease. But it wasn’t thought that lipids could have receptors, and it wasn’t ... Read More

Anna Arabia, the only child of Kathy and Joe Arabia of North Adams, Massachusetts, was 13 when she was diagnosed with gliomatosis cerebri, a rare, rapidly-growing brain cancer. Unlike other tumors, gliomatosis cerebri does not form into lumps; instead it is threadlike, invading multiple lobes of the brain, making it impossible to remove surgically. Anna ... Read More
Following blood stem cells in the body could yield better, safer treatments
Blood stem cells make all the different kinds of blood and immune cells in our body. Scientists have long been trying to make these cells in the lab and use them to make different blood cell types on demand. Mastering these feats could help make bone marrow transplants more efficient and less toxic, and could ... Read More
Anabella’s story: Hope for treating malignant rhabdoid tumors
Watching her deftly maneuver a playground with a huge smile on her face makes it hard to imagine that Anabella Trillo, 3, once faced challenges far greater than a jungle gym. In fact, she has already endured surgery, radiation, chemotherapy, and a stem cell transplant for one of the most aggressive pediatric cancers: a malignant rhabdoid ... Read More
Going into science: Women scientists at Boston Children’s offer advice to girls

Here is some of what they had to say. The scientists also offered their advice for girls interested in entering the field. ... Read More
Could leukemia be stopped before it starts?
Acute myeloid leukemia (AML), a blood cancer affecting both adults and children, requires more than one genetic “hit” to develop. As we age, many of us acquire a mutation that enables certain of our blood cells to multiply faster than others, forming their own distinct population. This first hit, known as “clonal hematopoiesis of indeterminate ... Read More
Eva rides out the side effects of aggressive Wilms tumor treatment
Eva Quiroz loves horses. The 10 year old takes riding lessons, and this activity puts a smile on her face. Anyone watching her contentedly guiding a horse around the ring would just assume she has always been a healthy child, says her mom Carla. They would see no hint of what Eva has been through ...
