Season 8 Episode 7: Stiff Person Syndrome, Cat's Kidneys and Dr. Vikram Baliga on the Wonder of Plants!

A rare autoimmune disorder can feel invisible until it steals someone’s movement, and stiff person syndrome is one of the starkest examples. We break down what’s happening in the nervous system when GABA-driven “calm down” signals get disrupted by autoantibodies, why symptoms can escalate into severe spasms and rigidity, and why the condition has captured public attention through Celine Dion’s story.

Then we shift from symptoms to source: an experimental CAR T-cell therapy designed to eliminate the B cells that produce the harmful antibodies in stiff person syndrome. We walk through what a phase two clinical trial reported, including real-world changes like faster walking and fewer people needing walking aids, plus the caveats that matter for anyone following medical research such as side effects, small sample sizes, and unknown durability.

Pet parents get a deep dive too. Chronic kidney disease in cats is common, progressive, and often detected late, so we cover a promising approach involving AIM protein and recombinant AIM therapy (RAIM) injections, including how researchers tracked toxins like indoxyl sulfate and what survival outcomes looked like over a year. 

Finally, plant scientist Dr. Vikram Baliga joins us to make botany feel urgent and strange in the best way, from ancient bristlecone pine “time capsules” to crown shyness and the science of how plants sense nearby competitors, plus a glimpse at nitrogen-fixing corn research that could reduce fertilizer dependence.
