S2E24 The Tick, the Table, and the Timeline: How a Tick Bite Rewrites Dinner
In this episode of Infectious Dose, Heather explores one of the strangest allergic conditions modern medicine has ever identified: a syndrome in which a tick bite can trigger an allergy to mammalian meat weeks, months, or even years later.
Why do symptoms often appear in the middle of the night instead of immediately after a meal? How did a cancer drug help scientists solve the mystery? Where does the alpha-gal molecule come from, and why do ticks seem uniquely capable of triggering this unusual immune response?
Join us as we follow the trail from the woods to the dinner table and unravel the science behind alpha-gal syndrome.
In this episode:
• What alpha-gal syndrome is and how it develops
• The surprising role of the Lone Star tick
• The cancer drug clue that helped solve the mystery
• Why reactions are delayed for hours after eating
• Diagnosis, testing, and common misconceptions
• Living with AGS and preventing future tick bites
• Separating evidence from conspiracy theories
Part of our June series, Stories of Summer Rain, this episode explores how warm, wet environments shape the ecosystems around us—and how those ecosystems can unexpectedly shape our health.
