Could a GI bug’s toxin curb hard-to-treat breast cancer?
Clostridium difficile can cause devastating inflammatory gastrointestinal infections, with much of the damage inflicted by a toxin the bug produces. But research from Boston Children’s Hospital suggests that the same toxin could also be a useful tool for curbing highly aggressive triple-negative breast cancers that don’t respond to chemotherapy. Min Dong, PhD, in the Department ... Read More about Could a GI bug’s toxin curb hard-to-treat breast cancer?

Infantile spasms: Speeding referrals for all infants
Infantile epileptic spasms syndrome (IESS), often called infantile spasms, is the most common form of epilepsy seen during infancy. Prompt diagnosis and referral to a neurologist are essential. Infantile spasms can present subtly, and research indicates that diagnosis is often delayed. Additionally, infants are especially likely to experience delays in referral to a neurologist if ...

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

Sickle cell gene therapy and boosting fetal hemoglobin: A 75-year history
Ed. Note: This post updates an earlier post from 2018. In a landmark decision today, the Food and Drug Administration (FDA) approved two gene therapies for sickle cell disease. One of them, Casgevy, has deep scientific roots at Boston Children’s Hospital — and is also the first therapy using CRISPR gene editing to gain FDA ...

Could ADHD be diagnosed genetically?
Despite it being very common, ADHD is often missed until a child reaches age 7 or older. By that time, they have likely been struggling socially and in school. Could early genetic testing be part of the solution? Anne Arnett, PhD, in partnership with Ryan Doan, PhD, at Boston Children’s Hospital, set out to see ...

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 ...

Gold particles and light could melt venous malformations away
Venous malformations — tissues made up largely of abnormally shaped veins — are often difficult to treat, especially when located in sensitive areas like the eyes, face, and genitourinary organs. In the worst cases, the lesions are disfiguring and can crush or obstruct surrounding tissues, cause bleeding and clotting, interfere with breathing or vision, or ...

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?
