Function preservation2

  • Rapid killing delays immune protection when cells cannot meet before antigen display ends

    Where this hypothesis actsAfter accelerated killing shortens antigen display below the time needed for all required responders to be primed

    What is proposedExtend the duration of usable antigen display

    With whatNot stated in the record

    HowPreserve nonreplicating antigen to extend the window available for productive priming contacts

    Possible resultPossible recruitment of previously unprimed responders and rescue of adaptive-response onset

  • Immune regulation hides target peptides, containing self-attack but weakening surveillance

    Where this hypothesis actsTarget cells under compensating regulation after infection interrupts central self-antigen sampling

    What is proposedRetain protective peptide presentation while removing pathogenic self-peptide presentation

    With whatProtein or peptide as the agent

    HowPerturb implicated antigen-processing enzymes and use calibrated peptide loading to test selective restoration of peptide presentation

    Possible resultPossible containment of autoreactivity while retaining antiviral and abnormal-cell surveillance
