Innate immunity was long thought to be devoid of immunological memory until a landmark study a decade ago introduced the concept of #TrainedImmunity.
Today, we invite research to a new Focus Issue on Trained Immunity. Find out more and spread the word. #Immunology

Nice papers that #neutrophils can also be epigenetically reprogrammed by infection - stemming from effects on stem cells.
Both use #zebrafish as model

Fascinating to see #trainedimmunity used to condition immunomodulatory responses.
I guess it's about inducing the right #epigenetic programme, and then the functional effect can be anything.

In addition to Liver, Aorta (#SmoothMuscleCell/#Pericyte/Fibroblast/Mɸ?) may
also oxidize #GutMicrobiota-derived trimethylamine/TMA into Trimethylamine N-oxide/TMAO
What is the local/Aortic vs circulating TMAO level?
