The hope to improve people’s lives is what drives many members of industry and academia to bring new products and therapies to market. At the BIO International Convention last week in Boston, there was lots of discussion about how translational science intersects with patients’ needs and why the best therapeutic developmental pipelines are consistently putting patients first.
“Our mission is to de-risk entry of new therapies in the ASD drug discovery and development space,” said Sahin, who is also a professor of neurology at Harvard Medical School.
One big challenge, says Sahin, is knowing how well — or how poorly — autism therapies are actually affecting people with ASD. Externally, ASD is recognized by its core symptoms of repetitive behaviors and social deficits. …
This is the third year that Jacob Works has made the trip down to Boston Children’s Hospital from Maine. With research assistant Haley Medeiros, he looks at pictures, answers questions, manipulates blocks and mimes actions like knocking on a door. His father, Travis, and another research assistant look on through a window.
“At first, we had to practically bribe him with an iPad with every task,” Travis says. “This year he’s more excited, because he understands more and is more confident and able to share more.”
Jacob, 11, was diagnosed in 2011 with Phelan-McDermid Syndrome, a rare genetic condition that typically causes children to be born “floppy,” with low muscle tone, and to have little or no speech, developmental delay and, often, autism-like behaviors. At the time, Jacob was one of about 800 known cases. But through chromosomal microarray testing, introduced in just the past decade for children with autism symptoms, more cases are being picked up. …
How can we better understand and support people with autism? And how can we tell if an intervention is working? Those are among the questions being asked in the Faja Laboratory, where Susan Faja, PhD, and her team study social and cognitive development in children, teens and young adults with autism spectrum disorder (ASD), using a variety of tools.
Originally on Snapchat, this video walks through some of these studies, including:
Individual Development of Executive Attention (IDEA), looking at executive functioning in 2- to 6-year-olds with autism, developmental disability or no developmental concerns. Executive functions include the ability to plan, manage complex or conflicting information, problem-solve and shift between different rules in different situations. By observing young children while they play hands-on tabletop games, Faja’s team is trying to find out: do kids with autism have problems with executive functioning early on, or do problems emerge later as a result of autism itself? The study is an extension of the ongoing GAMES project for 7- to 11-year-olds, in which children play video games designed to boost their executive functions. Faja is also looking to teach parents to use the games with their children at home.
Autism Biomarkers Consortium for Clinical Trials (ABC-CT), a multi-institution study that’s seeking objective, reliable measurements of social function and communication in people with autism. “Language, IQ and social assessments are not so sensitive when you’re looking for changes in autism symptoms, especially subtle ones,” says Faja. So her team is using physiologic measures — like EEGs to measure brain activity and eye-tracking technology to measure visual attention — and correlating them with behavioral and cognitive assessments. The ultimate goal is to validate a set of tools that can be used in clinical trials — and in day-to-day practice — to objectively measure and predict how children with ASD will respond to treatment.
Competence in Romance and Understanding Sexual Health (CRUSH), a new study, will enroll young adults with autism and their parents. The goal is to develop curriculum around dating and sexual health that meets the needs of the ASD population, starting with interviews to determine their needs and interests. No evidence-based curricula currently exist for adults on the spectrum, says Faja.
Since we spoke with the founders of TriVox Health in 2014, their disease management program has taken off. The program began in Boston Children’s Hospital’s Division of Developmental Medicine as a way to more efficiently collect information on children’s ADHD symptoms from parents and teachers. It is now a user-friendly, web-based platform for tracking multiple conditions, incorporating medication confirmation, side effects reporting, disease symptom surveys and quality of life measures.
When 2015 MacArthur “genius” grant winner Beth Stevens, PhD, began studying the role of glia in the brain in the 1990s, these cells—“glue” from the Greek—weren’t given much thought. Traditionally, glia were thought to merely protect and support neurons, the brain’s real players.
But Stevens, from the Department of Neurology and the F.M. Kirby Neurobiology Center at Boston Children’s Hospital, has made the case that glia are key actors in the brain, not just caretakers. Her work—at the interface between the nervous and immune systems—is helping transform how neurologic disorders like autism, amyotrophic lateral sclerosis (ALS), Alzheimer’s disease and schizophrenia are viewed. …
Funding drives biomedical research, and research drives treatment innovation. Access to funds, particularly National Institute of Health (NIH) awards, is critical to move research forward. The 21st Century Cures Act, which passed the U.S. House on July 10, could give the NIH $8.75 billion more in new grants to disperse over the next five years, the largest increase since the Recovery Act of 2009.
How would those funds be used? Can research find a better way to treat patients? Prevent disease? Disseminate advances in medicine?
In 2014, Boston Children’s led the U.S. in NIH awards. Here’s a look at how a few research teams are leveraging NIH funding to improve care for both children and adults.

Second in a two-part series on circadian biology and disease. Read part 1.
We are oscillating beings. Life itself arose among the oscillations of the waves and the oscillations between darkness and light. The oscillations are carried in our heartbeats and in our circadian sleep patterns.
A new study in Cell shows how these oscillations reach all the way down into our cells and help mastermind the timing of protein production. …
Last week was a good week for neuroscience. Boston Children’s Hospital received nearly $2.2 million from the Massachusetts Life Sciences Center (MLSC) to create a Human Neuron Core. The facility will allow researchers at Boston Children’s and beyond to study neurodevelopmental, psychiatric and neurological disorders directly in living, functioning neurons made from patients with these disorders.
“Nobody’s tried to make human neurons available in a core facility like this before,” says Robin Kleiman, PhD, Director of Preclinical Research for Boston Children’s Translational Neuroscience Center (TNC), who will oversee the Core along with neurologist and TNC director Mustafa Sahin, MD, PhD, and Clifford Woolf, PhD, of Boston Children’s F.M. Kirby Neurobiology Center. “Neurons are really complicated, and there are many different subtypes. Coming up with standard operating procedures for making each type of neuron reproducibly is labor-intensive and expensive.”
Patient-derived neurons are ideal for modeling disease and for preclinical screening of potential drug candidates, including existing, FDA-approved drugs. Created from induced pluripotent stem cells (iPSCs) made from a small skin sample, the lab-created human neurons capture disease physiology at the cellular level in a way that neurons from rats or mice cannot. …
The sad experience of abandoned children in Romanian orphanages continues to provide stark lessons about the effects of neglect and deprivation of social and emotional interactions. The long-running Bucharest Early Intervention Project (BEIP) has been able to transfer some of these institutionalized children, selected at random, into quality foster care homes—and documented the benefits.
In a review article in the January 29 Lancet, BEIP investigator Charles A. Nelson, PhD, and medical student Anna Berens, MsC, both of Boston Children’s Hospital, make a strong case for global deinstitutionalization—as early in a child’s life as possible. Currently, it’s estimated that at least 8 million children worldwide are growing up in institutional settings.
The BEIP studies have documented a series of problems in institutionalized children, especially those who aren’t placed in foster care or are placed when they are older: …
It’s become clear that our DNA is far from identical from cell to cell and that disease-causing mutations can happen in some of our cells and not others, arising at some point after we’re conceived. These so-called somatic mutations—affecting just a percentage of cells—are subtle and easy to overlook, even with next-generation genomic sequencing. And they could be more important in neurologic and psychiatric disorders than we thought.
“There are two kinds of somatic mutations that get missed,” says Christopher Walsh, MD, PhD, chief of Genetics and Genomics at Boston Children’s Hospital. “One is mutations that are limited to specific tissues: If we do a blood test, but the mutation is only in the brain, we won’t find it. Other mutations may be in all tissues but in only a fraction of the cells—a mosaic pattern. These could be detectable through a blood test in the clinic but aren’t common enough to be easily detectable.”
That’s where deep sequencing comes in. Reporting last month in The New England Journal of Medicine, Walsh and postdoctoral fellow Saumya Jamuar, MD, used the technique in 158 patients with brain malformations of unknown genetic cause, some from Walsh’s clinic, who had symptoms such as seizures, intellectual disability and speech and language impairments. …
