What did studies of old blood exposure find?

1

Studies of old blood exposure measured one outcome, core microglia activation signature.

Core microglia activation signature

1 study
  1. Old blood exposure increases core microglia activation signature across reactive microglial populations in all brain regions tested.

    “we identified a core microglia activation signature including 13 genes ( Fth1, B2m, Cd9, Fcer1g, Selplg etc.) that were upregulated in aging, old blood exposure”
