New technique yields potential treatment for a common cause of autism
Since 2008, we have known that the 16p11.2 chromosomal region is linked with autism spectrum disorder (ASD). Now, researchers from Boston Children’s have developed a new way to study the effects of 16p11.2 deletion in human neurons. In the process, they also found a potential treatment, possibly expanding the therapeutic options for this specific cause ...

When worlds collide: Glycosylated RNAs upend cell biology as we know it
Cells in our body bristle with sugars known as glycans that other cells can recognize via specialized receptors. Glycans attach to and modify proteins and fats, thereby influencing how proteins fold, how cues are trafficked between cells, and other cell-to-cell interactions. As just one example of glycans’ importance, our blood types (A, B, O) depend ... Read More about When worlds collide: Glycosylated RNAs upend cell biology as we know it
Piecing together the preterm infant microbiome
The human microbiome — the collection of microbes living in the gut — is now recognized as an important contributor to health and disease. The environment, the host, and microbe-microbe interactions are all likely to shape the microbiome’s dynamics, but the unique roles of each are not well understood. Now, a Boston Children’s Hospital infectious ... Read More about Piecing together the preterm infant microbiome
Diversifying therapeutic antibodies: From one, come many with potential different uses
A new method for producing antibodies against disease could result in a wider variety of drugs for infectious diseases, immune disease, and even cancer. The immune system naturally produces enormous varieties of antibodies to fight diseases. Therapeutic antibodies — antibodies created against specific therapeutic targets — have been used for decades to either rev up ...

Sturdier spikes may explain SARS-CoV-2 variants’ faster spread
The fast-spreading U.K., South Africa, and Brazil variants are raising concerns and questions about whether current COVID-19 vaccines will protect against them. A structural biology study led by Bing Chen, PhD, at Boston Children’s Hospital now reveals how the D614G mutation — carried by all three variants — makes SARS-CoV-2 spread faster. Key takeaways: The main ... Read More about Sturdier spikes may explain SARS-CoV-2 variants’ faster spread
Looking for cancer’s Achilles heel: The Pediatric Cancer Dependency Map
Thanks to developments in precision medicine, some adult cancers are now treated with designer drugs that target the genetic mutations that caused them. But most children with cancer have not reaped the same benefits. Unlike adult cancers, childhood cancers carry few genetic mutations. And the mutations these tumors do have are typically harder to make ... Read More about Looking for cancer’s Achilles heel: The Pediatric Cancer Dependency Map
How do patients with cystic fibrosis respond to COVID-19? An ‘airway in a dish’ may give answers
So far, based on clinical data, patients with cystic fibrosis (CF) don’t appear to be especially susceptible to COVID-19. And when they do get infected, they don’t seem to get sicker. But Ruobing (Ruby) Wang, MD, who cares for patients with CF in the Division of Pulmonary Medicine at Boston Children’s Hospital, thinks there is ...

Specialized T cells protect against the deadliest form of malaria
Each year, there are about 230 million cases of malaria globally. Children under the age of 5 are at highest risk of serious illness and death, accounting for about 265,000 deaths, or nearly 70 percent of all malaria deaths worldwide. Despite significant time and money poured into efforts to develop an effective malaria vaccine, the ... Read More about Specialized T cells protect against the deadliest form of malaria
‘Mosaic’ gene mutations could explain some cases of autism
The causes of autism remain mysterious. Scientists have linked autism spectrum disorder to a long list of genes, but most children with autism have no known explanation. Two new studies add to the picture, implicating mutations that affect only a fraction of a child’s cells. Called mosaic mutations, they open a new avenue for research ...

Therapy developed at Boston Children’s stops preeclampsia before it starts
Preeclampsia occurs in about 3 to 5 percent of all pregnancies. Characterized by very high maternal blood pressure, it can lead to serious, sometimes fatal, complications in both mother and baby. In severe cases, early delivery is often the only effective treatment, usually before the baby’s lungs are fully developed. Researchers within the Division of ...
