What if sudden OCD, tics, and food restriction after an infection aren’t “all in the head,” but start with immune cells carrying a biochemical message to the brain? We sit down with Dr. Fulvio d'Acquisto—immunologist, psychotherapist, and founder of affective immunology—to trace the language between emotions, living conditions, and the immune system, and why that conversation can erupt into neuropsychiatric symptoms in PANDAS and PANS.

Fulvio introduces Immuno-moodulin (iMood), a small protein produced by T cells, found in higher levels in people with OCD and elevated in PANDAS/PANS. He explains how iMood behaves like an intrinsically disordered protein: it can cluster in blood, cross into the brain, and temporarily disrupt neural communication—then disassemble as triggers fade. That dynamic process mirrors real life: flares during infections, relief during remission, and stubborn persistence in complex cases. We unpack why peripheral therapies—antibiotics, IVIG, and plasmapheresis—can reshape central symptoms, and why response varies based on disease staging rather than a one-size-fits-all pathway.

We also explore the bigger map: proteomics that can distinguish PANDAS from controls with striking accuracy, autoimmune conditions that cluster with specific psychiatric diagnoses, and a cautionary tale where “schizophrenia” resolved after immune therapy revealed underlying lupus. Along the way, Fulvio reframes inflammation as a repair system gone repetitive, not an enemy to be extinguished at all costs. And beyond the lab, we talk belonging—how shared meals, genuine dialogue, and community aren’t soft add-ons but active inputs that steady immunity and help people reclaim identity, empathy, and meaning.

If you’re curious about immune-brain crosstalk, novel protein targets, and why conversation can be medicine, this deep dive offers science you can hold and stories you’ll remember. Subscribe, share with someone who needs hope, and leave a review to help more families and clinicians find this work.
