Source sentences:
text: The innate response is usually triggered when microbes are identified by pattern recognition receptors, which recognize components that are conserved among broad groups of microorganisms, or when damaged, injured or stressed cells send out alarm signals, many of which (but not all) are recognized by the same receptors as those that recognize pathogens.

text: The acquired immune response is triggered by recognizing foreign antigen in the cellular context of an activated dendritic cell.
text: Adaptive immunity also creates “immunological memory” once an initial response to a specific pathogen has been triggered, which can enhance future responses to that specific pathogen and act more efficiently.
text: If a pathogen gets past all these defences and manages to infect tissue cells, an immune response is triggered.
