Leibniz-HKIHow does the gut stay healthy during worm infections? 🛡️🪱 A new Canadian-German study in #Cell shows #interferons help protect tissue. Not by killing worms, but by boosting gut resilience!

The EMBO JournalMICa/b-dependent activation of natural killer cells by CD64+ inflammatory type 2 dendritic cells contributes to #autoimmunity
Pathology of primary Sjögren's syndrome is known to involve #interferons, but Enrique Martin-Gayo et al @UAM_Medicina show additional roles also for #innateimmune cells like natural killer and #dendritic cells

@chfloudas It also brings up the question, what type of #ImmuneResponse delivers the best impact against the tumor bulk...suggestive of non-canonical responses beyond #interferons or synergistic #innateimmunity activation #immunology
