CHLA Researcher Probes Immune Mechanisms Behind Rare Pediatric Neuroinflammatory Diseases
She saw an invention change her life and wanted to build something that helps
Mark
Why does a profile like this matter beyond one researcher's story?
Mimi
Because it describes a specific scientific bet. Levine is studying rare childhood brain and nerve inflammation, where diagnosis and treatment are still imprecise, and she's starting with the immune mechanisms underneath.
Mark
What is the concrete work right now?
Mimi
A multi-omics pipeline aimed at neuromyelitis optica spectrum disorder, which affects the brain, spinal cord, and optic nerves. A few patients had monogenic causes, and their variants pointed to type 1 interferon signaling.
Luke
How strong is that interferon link, though? She says a few patients.
Mimi
Right, it's a small number, and she describes it as something she's looking into as a component of the disease, not a settled cause.
Luke
So nothing here shows it explains NMOSD generally.
Mimi
Correct. The piece reports no outcomes, no trial, no data on how many patients or how it generalizes.
Mark
And the longer-term goal?
Mimi
Using the pipeline across many pediatric neuroinflammatory conditions to guide treatment decisions.
Luke
That's an intention, not a result. Worth keeping separate from anything already achieved.
Mark
What's the human thread?
Mimi
Her own childhood with a pacemaker. She saw an invention change her life and wanted to build something that helps people too.
The Pulse
- Rare pediatric neuroinflammatory diseases can strike the brain, spinal cord, and optic nerves while leaving families and clinicians with few clear answers.
- Immune dysregulation in neuromyelitis optica spectrum disorder is being mapped through a multi-omics pipeline built to trace where the immune system goes astray.
- A handful of patients with monogenic forms of the disease have pointed investigators toward type 1 interferon signaling as a possible driver.
- The team is working to extend the same pipeline to other pediatric conditions, aiming to guide treatment decisions with more precision.
- No outcomes have been reported yet, so the interferon link remains a promising lead still awaiting confirmation across larger groups.
A young physician whose own childhood was shaped by a medical device now spends her days at Children's Hospital Los Angeles trying to understand why the immune system sometimes turns against the nervous system in children. Jesse M. Levine, leading work within the hospital's Neuroimmunology Program, is pursuing the hidden molecular mechanisms behind rare pediatric neuroinflammatory diseases, where much about diagnosis and treatment remains unknown. Her current effort, a multi-omics pipeline aimed at neuromyelitis optica spectrum disorder, has begun to point toward a particular immune signaling pathway as a thread worth following. The larger hope is quieter than a breakthrough: that understanding these mysteries more deeply will one day let children be diagnosed and treated with greater precision.
Jesse M. Levine, MD, PhD, traces her interest in medicine back to a pacemaker implanted when she was two years old. Those early years in hospitals left her with a conviction that clever ideas could change lives, and she carried that into college, where her attention settled on the brain and the nervous system.
During her training she kept being drawn to neuroimmunology, a field where illnesses can touch thinking, movement, feeling, and sight, yet where diagnosis and treatment still hold many open questions. She describes herself as someone who loves solving mysteries, and that appetite led her to Children's Hospital Los Angeles, first during a medical school rotation and later as an attending physician and investigator in the Neuroimmunology Program.
Her central work is uncovering the molecular roots of rare pediatric neuroinflammatory diseases, with the goal of more precise tests and therapies. One current project is a multi-omics pipeline examining how immune dysregulation unfolds in neuromyelitis optica spectrum disorder. In a few patients whose disease has a monogenic cause, the genetic variants pointed to type 1 interferon signaling, which she is now studying as part of how the disease develops.
Her plan is to apply this approach across other pediatric conditions. No results have been reported yet, and the interferon findings in that small group of patients will need to hold up as the work expands.
Jesse M. Levine, MD, PhD, had a pacemaker implanted when she was two years old. That early stretch in hospitals, she says, shaped the direction of her career. As a child she thought it remarkable that someone with an interesting idea had been able to invent a device that directly changed her life. She knew from then on that she wanted to create or innovate in a way that helped people.
In college, her attention turned to the brain, neurology, and neuroscience. During medical training she kept finding herself drawn to neuroimmunology patients. Their illnesses can bring psychiatric, cognitive, motor, and sensory effects, she explains, yet much remains unknown about how to diagnose and treat them. She describes herself as someone who likes solving mysteries, and she carried her interest in medical innovation into that field.
Her path led to Children's Hospital Los Angeles (CHLA). While in medical school she did an away rotation there and worked with Jonathan D. Santoro, MD. The experience prompted her to return later. She now works at CHLA as an attending physician and investigator in the Neuroimmunology Program, part of the Neurological Institute.
Her focus is the underlying molecular mechanisms of rare pediatric neuroinflammatory diseases. The ultimate aim, she says, is more precise diagnostics and therapeutics for these conditions. Getting there, in her view, requires a solid grasp of fundamental immunology and of how the immune system interacts with the nervous system in these diseases.
One of her current projects is building a multi-omics pipeline to evaluate the pathways of immune dysregulation in neuromyelitis optica spectrum disorder. The autoimmune condition affects the brain, spinal cord, and optic nerves. Her team has identified a few patients whose disease has a monogenic cause. The genetic variants in those patients implicated a particular immune signaling pathway, type 1 interferon, and she is now examining it as a component of how the disease develops.
Her longer-term plan is to apply the same pipeline to a range of pediatric neuroinflammatory conditions and use it to help guide treatment decisions. No results from that work have been reported yet. She says CHLA lets her strike an ideal balance between clinical work and research as a physician scientist.
Outside the hospital, Levine reads, explores thrift stores, antique stores, and restaurants around Los Angeles, and walks her dog, Cooper. What to watch is whether the interferon findings in the small group of patients with monogenic disease hold up as the pipeline is extended to other conditions.
