‘A lot better now’: Andrew’s recovery from Rocky Mountain spotted fever and a stroke
When Andrew was bitten by a tick in 2021, he and his parents could hardly have imagined that just a month later, he would be coping with a series of health problems that would culminate in a stroke. Andrew, then 7, didn’t even realize he’d been bitten until he began to feel sick with a ... Read More about ‘A lot better now’: Andrew’s recovery from Rocky Mountain spotted fever and a stroke
After a severe case of myelitis, ‘rockstar’ Maxwell is on the move
When Maxwell Lazarz’s mother, Jennifer, tells him he’s a rockstar, he just laughs and asks her what that means. But as this joyful almost-3-year-old zips around in his motorized wheelchair, cracking jokes and blowing bubbles, it’s clear that his mom is right. In fact, Maxwell has been defying expectations ever since he was diagnosed with ... Read More about After a severe case of myelitis, ‘rockstar’ Maxwell is on the move
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 ...

A deeper understanding of inflammatory pain could reveal new solutions
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are the main go-to for inflammatory pain caused by wounds, infection, sunburn, arthritis, and other triggers. NSAIDs work pretty well, but chronic use can cause side effects, and they aren’t equally effective for all sources of pain. Could we identify a more effective, safer analgesic that doesn’t involve ... Read More about A deeper understanding of inflammatory pain could reveal new solutions
Could SIDS be caused by unrecognized brain infections?
Some infants who pass away from sudden infant death syndrome (SIDS) are known to have had acute minor infections. Could these have played a role in their death? Using next-generation molecular tools, a new study provides evidence that undiagnosed inflammation and occult infection can contribute to SIDS and the brainstem pathology seen in some infants. ...

A promising target for ALS and other neurodegenerative disorders: Curbing inflammation
When cells recognize a danger, such as an infection, they activate the innate immune system. Sentinel molecules sound an alarm, recruiting immune cells to take down the threat. In 2016, Judy Lieberman, MD, PhD and her colleagues at Boston Children’s Hospital showed that a protein called gasdermin D initiates a final, decisive step: pyroptosis, a ...

A new angle on the cause of Alzheimer’s disease: Accumulating brain mutations
Alzheimer’s disease is marked by a loss of functional neurons in the brain. But what causes this loss? A new study reveals that people with Alzheimer’s have an abundance of newly acquired mutations in their neurons — more than people of the same age without Alzheimer’s, and enough to disable genes important to brain function. ...

The tiny choroid plexus protects the prenatal brain — but may also pass on inflammation from the mother
Floating in fluid deep in the brain are small, little-understood fronds of tissue. Two new studies reveal that these miniature organs are a hotbed of immune system activity. This activity may protect the developing brain from infections and other insults — but may also contribute to neurodevelopmental disorders like autism. Key takeaway This pioneering work ...

Pain neurons activate immune cells, opening new treatment possibilities
For a long time, pain and inflammation were thought to be two separate biological responses. But new research by Boston Children’s Hospital and international collaborators suggests that the same sensory neurons that produce pain also trigger inflammation. And they do so by activating cells of the immune system, a relationship never described before. This interaction ...

Targeting a rogue T cell prevents and reverses multiple sclerosis in mice
Multiple sclerosis is an autoimmune disease affecting both adults and children. It’s driven by “helper” T cells, white blood cells that mount an inflammatory attack on the brain and spinal cord, degrading the protective myelin sheath that covers nerve fibers. But there are many different kinds of T helper cells, and up until now, no ... Read More about Targeting a rogue T cell prevents and reverses multiple sclerosis in mice
