Very excited to share a new review with Dr. Ian Maze born out of my PhD work! 🧠🧬 We dive into how early life experiences shape the epigenetic landscape of the developing brain—and how these lasting changes may contribute to risk for affective disorders.

For #FluorescenceFriday✨ Exploring the beauty of the locus Coeruleus using IF staining: neurons🔵 surrounded by glowing astrocytes🟢 embracing delicate blood vessels🔴, alongside striking pTau signals💗. A vivid reminder of the cellular complexity shaping brain health and disease. #LC #Neuroscience
Here’s my Fluorescence Friday highlight: just got this beautiful shot from the locus coeruleus in our latest tissue section! You can see astrocytes (in green) glowing and wrapping around tiny blood vessels (in red), with pTau staining (in magenta) lighting up the scene. It’s wild how much is going on in just one microscopic field—so cool to see these markers all together and think about what they mean for brain health and Alzheimer’s research.
