New leads for spinal cord injury: Mapping spinal-projecting neurons in the brain
Only a fraction of people who sustain a spinal cord injury fully regain their motor function. While rehabilitation can help, scientists have long looked for ways to regenerate injured nerve fibers — including, at Boston Children’s Hospital, Zhigang He, PhD, BM. As part of a collaborative effort by the BRAIN Initiative Cell Census Network, which ... Read More about New leads for spinal cord injury: Mapping spinal-projecting neurons in the brain
Timing is everything: How circadian rhythms influence our brains
Why are we mentally sharper at certain times of day? A study led by Jonathan Lipton MD, PhD, at Boston Children’s Hospital spells out the relationship between circadian rhythms — the body’s natural day/night cycles — and the brain connections known as synapses. The work is the first to provide a cellular and molecular explanation ... Read More about Timing is everything: How circadian rhythms influence our brains
Naloxone on demand: Shining a light to reverse opioid overdose
Overdose deaths from fentanyl and other opioids are at record highs in the U.S. Naloxone, if delivered soon after an overdose, is proven to be life-saving. It binds to the same brain receptors that opioids use, thereby blocking opioids’ effects. A naloxone nasal spray (Narcan) is now available over the counter, but there are still problems ...

A new approach to C. diff? Targeting the inflammation, not the bacteria
Clostridium difficile (C. diff) intestinal infections can cause severe, debilitating diarrhea in patients who are hospitalized or on immunosuppressive therapies. The infections can be very hard to eradicate, roaring back when patients try to taper their antibiotics. Many people wind up on antibiotics for months and can become resistant to three or more of them. ... Read More about A new approach to C. diff? Targeting the inflammation, not the bacteria
Could we intervene in Huntington’s disease before symptoms appear?
Huntington’s disease is the most common single-gene neurodegenerative disorder and is characterized by motor and cognitive deficits and psychiatric symptoms. Work led by Beth Stevens, PhD, and Dan Wilton, PhD, in the Department of Neurology at Boston Children’s Hospital, now shows that the disease process begins well before symptoms appear. That raises the possibility of ... Read More about Could we intervene in Huntington’s disease before symptoms appear?
Research aims to pinpoint genetic connection between autism and heart disease
Cardiology and neurodevelopmental researchers have more questions than answers about the possible genetic links between congenital heart disease (CHD) and autism spectrum disorder (ASD). A study that’s underway at Boston Children’s aims to pin down those elusive answers by taking a close look at the genetics of children with neurodevelopment and cardiovascular conditions. The researchers want to see ... Read More about Research aims to pinpoint genetic connection between autism and heart disease
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 ...

Could the right dietary fat help boost platelet counts?
Aside from transfusions, there currently is no way to boost people’s platelet counts, leaving them at risk for uncontrolled bleeding. Could something as simple as a dietary change raise platelet counts in people with low levels, such as cancer patients receiving chemotherapy? New science out of the lab suggests that the answer might be yes. ... Read More about Could the right dietary fat help boost platelet counts?
Nanobodies from alpacas could steer immune attacks on influenza
While conventional flu vaccines are designed to anticipate the influenza strains projected to dominate in the next flu season, they’re only partially effective. And while antiviral drugs are available to treat active flu cases, the body quickly clears them, requiring high, frequent doses. Coupling one existing flu drug with a special ingredient from alpacas, the ... Read More about Nanobodies from alpacas could steer immune attacks on influenza
Zika study reveals how infection can cause microcephaly
Prenatal exposure to viruses capable of infecting the fetal brain, particularly in the first trimester, can cause a range of developmental defects in the baby. The Zika epidemic in Brazil during 2015-2016 posed an extreme case, causing hundreds of babies to be born with microcephaly, or an abnormally small head. Although cases have waned significantly, ...
