Evolving brain-immunity: From Ramón y Cajal’s mysterious butterflies to a garden sustained by immune cells as their nectar
Over the last three decades, dogma-breaking studies have refuted the brain’s assumed immune isolation. Echoing Ramón y Cajal metaphor of neurons as “butterflies,” Schwartz proposes viewing the brain a...

New work from the lab on how sickness reduces appetite. Turns out, it’s complicated :) We focused on a single inflammatory cytokine, IL-1b, and even that reduces appetite via multiple mechanism. Thanks to Nik Hayes for leading and sticking with this project and to everyone else who contributed!

China is waging war on Alzheimer’s. What can its approach teach the rest of the world?
The country is facing a coming wave of dementia for its ageing population, and is investing in research into drugs, diagnostics and even surgery to prepare itself.
