The Announcement of the Brain Prize 2026: A Milestone in Neuroscience
On March 5, 2026, the Lundbeck Foundation announced the winners of the Brain Prize 2026, recognizing groundbreaking work in brain research. Professors David Ginty from Harvard Medical School in the United States and Patrik Ernfors from Karolinska Institutet in Sweden were awarded this prestigious honor for their pioneering discoveries on how the nervous system senses touch and pain. Valued at €1.3 million (approximately DKK 10 million), the Brain Prize stands as the world's largest award dedicated to neuroscience, underscoring the global significance of their contributions to the somatosensory system—the network responsible for detecting mechanical, thermal, and painful stimuli.
The somatosensory system, often called the body's sensory map, translates physical interactions into neural signals that inform our sense of self and environment. Disruptions here lead to conditions like chronic pain or sensory hypersensitivities seen in neurodevelopmental disorders. This award highlights a transformative shift in understanding these processes, with direct relevance to European research institutions like Karolinska Institutet, a hub for molecular neurobiology.
Profiles of the Laureates: From Academia to Global Impact
David Ginty, the Edward R. and Anne G. Lefler Professor of Neurobiology and chair of Harvard's Department of Neurobiology, has dedicated decades to unraveling touch sensation. His career trajectory—from a PhD in physiology at East Carolina University to leading the Ginty Lab—has produced genetic toolkits that label and manipulate specific touch neuron subtypes in mice. These tools have revealed how low-threshold mechanoreceptors (LTMRs) in the skin detect gentle strokes, vibrations, and textures, transmitting signals via dedicated spinal pathways to the brain.
Patrik Ernfors, Professor of Tissue Biology and head of the Division of Molecular Neurobiology at Karolinska Institutet, complements this with expertise in pain-sensing nociceptors. His group's work on neurotrophins and genetic labeling has classified nociceptive neurons, linking them to joint pain in rheumatoid arthritis. Collaborating with immune cells, these neurons become hypersensitive through intracellular signaling cascades, paving the way for targeted therapies. Ernfors' research at one of Europe's premier medical universities exemplifies Sweden's leadership in neuroscience.
Together, their labs have synergized US-Swedish efforts, fostering transatlantic collaborations that accelerate somatosensory neuroscience.
David Ginty's Contributions: Decoding the Touch Landscape
Ginty's research began with neurotrophins like nerve growth factor (NGF), essential for sensory neuron survival. By the 2000s, his team shifted to touch, engineering mice expressing fluorescent reporters in Merkel cell-afferent complexes for gentle touch and Pacinian corpuscles for vibration. They discovered that LTMR subtypes project to distinct spinal cord layers, forming labeled lines—direct pathways avoiding crossover—for precise discrimination of textures and forces.
Recent advances link these circuits to autism spectrum disorders (ASD), where mutations heighten touch sensitivity, causing sensory overload. Ginty's lab at Harvard has modeled this, identifying therapeutic targets to dampen overactive neurons. His work, spanning molecular genetics to behavioral assays, has rewritten somatosensory textbooks, influencing curricula at leading neurobiology programs worldwide.
Patrik Ernfors' Innovations: Unraveling Pain at the Cellular Level
At Karolinska Institutet, Ernfors pioneered transcriptomic profiling of sensory neurons, classifying over a dozen nociceptor subtypes based on genetic markers. His discoveries revealed how these cells form end-organs in skin and joints, responding to inflammatory mediators. In arthritis models, nociceptors interact with immune cells via cytokines, amplifying pain through pathways like TRP channels (transient receptor potential ion channels, first identified in pain sensing).
A key breakthrough: intracellular signaling in nociceptors drives hyperexcitability. Blocking these—via antisense oligonucleotides—has entered Phase I trials by 4E Therapeutics, targeting rheumatoid arthritis pain. Ernfors' tools, shared openly, empower European labs studying neuropathic pain.
The Cellular Blueprint: Integrating Touch and Pain Pathways
Collectively, Ginty and Ernfors provided a somatosensory atlas: 15+ neuron classes, each wired to specific effectors (e.g., Meissner corpuscles for flutter, C-fibers for burning pain). Genetic fate-mapping showed conserved organization from periphery to brainstem, with spinal interneurons relaying modality-specific info.
- Touch: Rapidly adapting LTMRs for dynamic stimuli.
- Pain: Polymodal nociceptors integrating heat, chemicals, mechanics.
- Itch/Temperature: Dedicated pruriceptors and thermoreceptors.
This modularity explains disorders: chronic pain from nociceptor sprouting, touch aversion in ASD from LTMR hyperactivity.
Therapeutic Horizons: From Research to Pain Relief
These insights fuel precision medicine. Ernfors' arthritis drug targets hypersensitive nociceptors; Ginty's autism models suggest LTMR modulators. Europe leads trials: EU-funded projects at Karolinska test gene therapies silencing pain genes.Brain Prize site highlights clinician hope for non-opioid analgesics amid Europe's opioid crisis.
Phase II trials loom for 4E Therapeutics' candidate, potentially revolutionizing chronic pain management.
Chronic Pain Burden in Europe: A Public Health Imperative
Chronic pain affects 20% of Europeans (one in five adults), with high-impact cases (limiting daily life) at 15%. In Sweden, 20% report moderate-severe pain; EU-wide, it costs €500 billion yearly in lost productivity. Women, elderly, and low-SES groups suffer most.
Post-COVID, prevalence rose 10-15%, straining healthcare. Ginty-Ernfors work informs EU Pain Federation strategies for better diagnostics.
