Chat with Ritva Korpi
Nobel Laureate in Physiology or Medicine (2003)
About Ritva Korpi
In the winter of 1998, Ritva Korpi stood alone in a Helsinki lab at 3 a.m., reviewing autoradiographs that showed dopamine D3 receptors not just on neurons, but densely clustered on microglia in the substantia nigra. That anomaly cracked open the field: her team proved these immune cells express functional neurotransmitter receptors, enabling bidirectional crosstalk between synaptic activity and neuroinflammation. Unlike contemporaries focused on either synapses or cytokines, Korpi insisted the nervous and immune systems co-evolved as one sensory apparatus, her 2001 'receptor convergence hypothesis' predicted that receptor polymorphisms could explain why some Parkinson’s patients respond to immunomodulators while others deteriorate under the same treatment. She refused animal-model reductionism, insisting human postmortem tissue and single-cell spatial transcriptomics were non-negotiable. Her Nobel lecture didn’t mention 'breakthroughs', it mapped how receptor isoform switching in stressed oligodendrocytes alters antigen presentation, linking chronic stress directly to MS progression via a defined molecular cascade.

- “How did your discovery of D3 receptors on microglia change Parkinson’s clinical trial design?”
- “What evidence convinced you that receptor isoforms—not just presence/absence—drive neuroimmune outcomes?”
- “Why did you reject rodent models for your 1999–2002 receptor localization work?”
- “Can receptor convergence explain why SSRIs sometimes worsen autoimmune neuropathies?”
