Delving into the causes of attention deficits: Childhood adversity, lost sleep, and dopamine
New research on the effects of adversity in childhood ties together stress, sleep loss, and attention deficits later in life. It also uncovers some of the underlying brain biology and potential treatment approaches — while revealing a puzzling sex-specific effect. The lab of Takao Hensch, PhD, has long studied time windows during development — commonly ...

Shoring up heart muscle’s mini ‘managers’ to treat heart failure
Our heart muscle is studded with tiny dyads, intricately designed structures that manage incoming electrical signals and calcium release to coordinate our heartbeats. Could gene therapy help maintain dyads’ structure and boost the function of failing hearts? A new study suggests it can. “We know that in heart failure from many causes, dyads become disorganized,” says ... Read More about Shoring up heart muscle’s mini ‘managers’ to treat heart failure
Finding a possible genetic treatment for rare arrhythmias
Variants in a gene that plays a key role in heart function can cause potentially life-threatening arrhythmia syndromes known as calmodulinopathy. Calmodulinopathy is rare and causes arrhythmias that are poorly treated by current options. Boston Children’s cardiologist William Pu, MD, believes he has found a promising custom genetic treatment: antisense oligonucleotides that deplete the disease-causing gene product. ...

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
Humble cells in a little-known organ manage brain inflammation
Deep in the brain, sheets of tissue known as the choroid plexus produce cerebrospinal fluid (CSF) and act as a protective barrier between the brain and CSF. But the lab of Maria Lehtinen, PhD, at Boston Children’s Hospital has shown that the little-known choroid plexus does much more. For example, it secretes factors that promote ...
