6/6 🧵
The killifish compresses decades of human immune aging into weeks, with conserved biology across vertebrates. This model could accelerate the search for therapies targeting immune decline — potentially improving healthspan by stopping "inflammaging" before it cascades.

5/6 🧵
The team built KIAMO, an open multi-omics platform with single-cell transcriptomics, proteomics, and imaging data. This resource lets the global research community study immune aging mechanisms in fast-forward and test interventions that could work in humans.
4/6 🧵
Functional proof: immune cells from old fish barely responded to bacterial threats compared to young fish. But here's the twist — treating cells with a senolytic drug partially restored youthful immune function in vitro. The damage isn't entirely locked in.
3/6 🧵
Their immune stem cells accumulated DNA double-strand breaks and stopped repairing themselves properly. These cells entered senescence — stuck in a zombie state, unable to differentiate into functional immune cells. The immune factory was breaking down.
2/6 🧵
The killer finding: "inflammaging" — chronic inflammation that accelerates with age. Old killifish showed spiking acute-phase proteins and metabolic chaos in their blood, mirroring the exact inflammatory signatures linked to age-related diseases in mammals and humans.
1/6 🧵
Scientists just cracked immune aging using a fish that lives 4 months. The turquoise killifish ages so fast, researchers watched the entire immune decline process in weeks — revealing the same inflammatory breakdown, DNA damage, and immune failure seen in humans.
