Pre-ChorusMaps of genes like constellations, markers in the skin,Antigen doors and the keys they hide — a tug beneath the din,A fragile balance tipping where the immune story begins. ChorusWe found the locks and the keys in the language of our cells,MHC class II showing the pieces, the tale the body tells,A pulse becomes a beacon, turning mystery into light,Population voices rising — from shadow into sight. Verse 2Hundreds of signposts scattered, missense whispers in the chain,Heritability written in the places memory remains,Linked to breath and joint and mind, small echoes that persist,A pattern in the crowd, an invisible fist. BridgeTwenty-two lighthouses marked along a genome shore,Immune programs waking in B cells and the doors they wore,Stronger presentation, less lingering song — a mechanistic core. Final ChorusSo raise the strings and light the sky, let the chorus swell and hold,Population-scale searching turns the quiet into gold,From masked repeats to open maps, the hidden becomes known,Echoes in the blood now answer — we are not alone.
