Sex-specific APOE4-dependent innate immunity regulates meningeal lymphatics, brain lipids, neuroinflammation, and cognition
Delivanoglou et al. show that expression of APOE4, a risk factor for Alzheimer’s disease, leads to sexually dimorphic lymphatic and inflammatory responses in mice and humans alike. Suppressing APOE4-induced innate immunity had contrasting effects on cognition in females and males, highlighting the need for immunotherapies tailored to each sex.

🚨 Our study is online @cp-neuron.bsky.social! A fun read for all you neuroimmunology aficionados! This study proposes that targeting innate immunity/lymphatics in female & male E4 carriers might lead to different cognitive outcomes, highlighting the need for immunotherapies tailored to each sex. 👇

Most assume implants fail slowly over months. The moment an electrode enters the brain, microglia rush toward it within seconds, like fingers reaching for a splinter. Blood vessels leak. The BBB breaks. Inflammation starts instantly. #BCI #NeuralEngineering #Neurotech
