Blockade1

  • A microbial protease may limit skin inflammation through a nerve-to-immune signal

    Where this hypothesis actsSensory neurons innervating skin after scratching has been prevented

    What is proposedSelectively switch off PAR1 in neurons to test its role

    With whatNot stated in the record

    HowSelective receptor shutdown in neurons in an experimental model; the technique is not stated

    Possible resultExpected disappearance of the beneficial effect of V8
