    7/7 🧵

    Bottom line: immune aging follows deep evolutionary patterns conserved across vertebrates. The killifish gives us a compressed timeline to test what actually works—not just theory, but interventions we can validate in weeks, not decades.

    Researchers launched KIAMO (Killifish Immune Aging Multi-Omics)—a public platform with single-cell transcriptomics, proteomics, and imaging data. Open-source aging research at scale.

    The functional test: Immune cells from old killifish barely respond to bacterial threats compared to young fish. But here's the twist—pre-treating cells with a senolytic drug partially restored youthful immune responses in vitro.

    The kidney marrow (fish equivalent of bone marrow) shows dramatic age-related damage: fibrosis, tissue remodeling, and immune stem cells accumulating DNA damage faster than replication alone can explain. Classic cellular senescence.

    Key finding: "Inflammaging" is real. Older killifish show the same chronic inflammation seen in aging humans—elevated acute-phase proteins, metabolic imbalance, and systemic inflammatory markers tied to age-related diseases.

    The turquoise killifish (Nothobranchius furzeri) lives just a few months, letting researchers watch immune aging in fast-forward. What takes decades in humans happens in weeks—making it a game-changer for testing interventions.

    Tiny fish that live only months are unlocking secrets of human immune aging—and they're showing us that getting old might not be as inevitable as we thought.
