How- ever , a growing line of evidence indicates the immune system That in insects , crustaceans and molluscs can recognize and remember Specifically infection with Certain Pathogens . Involvement of multiple isoforms of pattern recognition receptors containing variable Ig domains , eg . Dscam insect and snail FREPs is implicated in specific recognition of different Pathogens and in selection of Immune Competent fagocytes .
